Akuve kumnandi ukubabaza imibala ekhanyayo ye-dahlia engadini! Izinhlobonhlobo bobunjwa nemibala yalezi zifudumele nezinye izitshalo ezifuywayo kakhulu ziyamangaza futhi ziyathandeka. Igama lokuqala lanikezwa ama-dahlia ama-Aztec, alibiza ngokuthi "aktil". Zenziwe ngama-Aztec namaMayan asendulo, kwakhula izimbali ukuhlobisa amathempeli eLanga nemicikilisho yokukhulekelwa kwelanga. Bathi iziqu zabo eziyize zazisetshenziswa ngalezozinsuku njengamapayipi amanzi. Namuhla, ama-dahlias angatholakala cishe kuyo yonke ingadi. Ngemuva kwakho konke, ngaphezu kokuhlobisa okuphezulu, banenzuzo eyodwa enkulu - ukungabekezeleli ekuhambeni. Imininingwane iku-athikili.
Dahlias engadini
Incazelo yeBotanical Dahlia
Izitshalo zisetshenziswa ezinezimpande ezinamanzi, izimpande ze-tuberoid-thickened, ziqonde ziqonde, ziqhekekile, zibushelelezi noma ziqinile, ziyize, zifinyelela ku-250 cm ubude. Amaqabunga ancwebile, kwesinye isikhathi kabili noma kathathu, maningi amaba, ubude bawo buyi-10-40 cm, okuhlukahluka okuhlukahlukene, okuluhlaza okotshani noma onsomi.
I-inflorescences dahlia - obhasikidi, isiketi esenziwe sendebe, siqukethe imigqa emi-2 amaqabunga aluhlaza, efafazwe phansi. Izimbali ezinqabile zingumhlanga, zinkulu, ngemibala ehlukahlukene nobukhulu; eziphakathi nendawo zibomvu, ziphuzi zegolide noma zibomvu onsundu, izithelo ziyi-achene.
I-genus dahlia ihlanganisa, ngokusho kwemithombo ehlukahlukene, kusukela ezinhlotsheni ezine kuya kwezingama-24, ezisakazwa ikakhulu ezindaweni zezintaba zaseMexico, Guatemala, naseColombia.
Ukukhetha indawo engadini nokutshala i-dahlia
Ngokukhula kwe-dahlias, udinga ukukhetha ilanga, elivikelwe ezindaweni ezinomoya obandayo futhi onamandla ngokujikeleza komoya okuhle. Awukwazi ukubatshala ezindaweni eziphansi nezinamanzi. Ibanga ngesikhathi sokutshala lincike ekuphakameni nasekwenzeni kwesihlahla solunye uhlobo noma kwesinye. Indawo ekhethwe i-dahlia kufanele ikhanyiswe okungenani amahora ayisithupha ntambama.
Esifundeni esiphakathi, ama-dahlias atshalwe emhlabathini ovulekile ekupheleni kweminyaka eyishumi yokuqala kaJuni, lapho ingozi yokudlulela ngasekupheleni kukaJuni idlula. Bemba umgodi osebeni lomfosholo, beshayela isigxobo esingu-130-150 cm ubude ukuhlanganisa "isihlahla" esizayo, bafakwe emgodini, uma inhlabathi idinga lokho, umquba ojikelezayo, u-20-30 g we-superphosphate, uhlanganise konke kahle, amanzi amaningi bese utshala ishubhu ngenhlama yomhlaba , pre-ukhule ekhaya kufasitela noma ku-greenhouse.
Lapho itshalwe kahle, intamo yomsuka we-dahlia kufanele ibe ngu-2-3 cm ngaphansi kwezinga lomhlabathi. Isitshalo ngemuva kokutshala siboshwe esigxotsheni. Ngemuva kwalokho i-garter iyenziwa njengoba isisindo semvelo sesihlahla sikhuphuka. Ukunakekelwa okwengeziwe kubandakanya ukunisela okuvamile, ukhula, ukukhulula, ukugqoka okuphezulu.
Ungayinakekela kanjani i-dahlias?
Ukunakekelwa kukaDahlia kufaka phakathi ukwelusa, i-garter yesikhathi esithile kuya kwezikhonkwane, ukuchelela njalo nokugqoka okuphezulu okufika ngesikhathi. Phambilini, akufuneki kushiywe ama-buds amabili ku-tuber ngayinye, ngokuzayo, amahlumela asele aqhekekile ukuze anganciphisi ukukhula kwabakhulu. Izikhonkwane ze-garter dahlia drive ngaphambi kokufika. Ukuphakama kufanele kube ngu-40 cm ngaphansi kokuphakama okulinganiselwe kwesitshalo uqobo.Iziqu ziqala ukuboshwa lapho zifika ku-30 cm futhi ziqhubeke nokwenza lokhu njengoba zikhula ukuze zivikeleke ukuba zingaphumi.
Izitshalo zokutshala zinenhloso efanayo. Ukuze uthole izimbali ngaphambili, kubalulekile ukususa njalo izithombo ezikhula kancane - amahlumela akamuva akhula kuma-axils amaqabunga, futhi lokhu kufanele kwenziwe ngokushesha ngangokunokwenzeka ukuze kulimaze isitshalo kancane. Kusukela kulesibili lamahlamvu, amahlumela aseceleni asele ukuze akhe isihlahla. Amabanga aphansi we-dahlia awazali.
Ukuthola ama-inflorescence amaningi alungele ukusikwa, cindezela ihlumela eliyinhloko ngaphezulu kwesibili kwamaqabunga, amahlumela asohlangothini olungaphezulu abunjwe ngaphezulu kwesibili. Isigaxa esiphakathi siyasuswa, okuholela ekwandiseni nasekuqiniseni i-peduncle, ukwanda ngosayizi wama-inflorescence. Lokhu kubalulekile ikakhulukazi lapho kukhula imibukiso ye-dahlias. Uma ama-inflorescence engazange asikwe, khona-ke ayasuswa lapho nje eqala ukuqhakaza. Ngaphandle kwalokho, ukubukeka kokuphangwa kwezitshalo nokukhula kwamahlamvu amasha kuyabambezeleka.
UDahlia unqamula uMelody Mambo
Ukondla i-dahlia kwenziwa ngemuva kokuthi izitshalo sezinezimpande ngemuva kokutshala (hhayi ngaphambi kwezinsuku ezingama-5-7), ngokuphumula kwezinsuku eziyi-10 emva kokunisela isitshalo. Eduze kwesihlahla yenza umgodi ngokujula kuka-10-12 cm, okuphakelayo, bese unika umgodi ngokushesha. Okondla (izikhathi ezi-3-4) sebenzisa ukumiliselwa kwe-mullein (1: 10), engeza umanyolo we-superphosphate ne-nitrogen (20 g nge-10 l lamanzi) kuyo. Kuhle futhi ukufeza ukudla kwe-3-4 nge-superphosphate (50 g nge-10 l lamanzi) ngokufakwa kwezandla ezi-3-4 zomlotha wokhuni.
Ngalokhu kunakekelwa, izimbali eziningi ze-dahlia ziyafinyeleleka nosayizi wama-inflorescence akhudlwana. Ukugqoka okuphezulu kwenziwa ngoJuni nengxenye yokuqala kaJulayi, futhi ngo-Agasti, ukugqokwa okukodwa phezulu kwenziwa nge-potassium sulfate yokuvuthwa okungcono kwezilimo eziyizigaxa (30 g ngesihlahla ngasinye). Akufanele uthande kakhulu umanyolo we-nitrogenous, ngoba lokhu kunciphisa ukuqhakaza okuqhakaza izimbali, ihlathi lithola kuphela isisindo esikhulu semifino, ukuqhuma okubuthakathaka kanye namafomu ama-tubers agcinwe kahle. Kusukela ngoSepthemba, yeka ukuthambisa nokondla.
Maphakathi no-Agasti, kunconyelwa ukuthi ama-dahlias ambozwe ngo-8-12 cm ukuze avikele intamo yezimpande ekulimaleni kwesithwathwa. Kusukela ngoSepthemba, yeka ukuthambisa nokondla.
Ukuzala dahlia
Ukusakazwa kwembewu I-Dahlia isetshenziswa kakhulu eqenjini lezinhlobo ezingezona eziphindwe kabili nomsebenzi wokukhetha. Ukulungiselela izithombo, ukutshala imbewu kwenziwa ngoMashi-Ephreli emabhokisini anengxube ye-peat nesihlabathi (3: 1). Ukugwema izifo, imbewu ifakwa imizuzu emi-5 ukuya kwe-10 endaweni yesisombululo se-formalin (10 ml ka-40% wezidakamizwa nge-1 litre lamanzi), yomiswe ephepheni lokuhlunga. I-dahlia izithombo iyantshontshela, imvamisa ezitini ze-peat noma emabhodweni amancane obumba. Kutshalwe emhlabathini ovulekile ngemuva kokuqandeka kwentwasahlobo.
Okokusika Ekupheleni kukaFebhuwari kanye ekuqaleni kukaMashi, izimpande zezilimo eziyizigaxa zibekwa (ngemuva kokwelashwa ngesisombululo se-potanganum permanganate semizuzu eyi-15), emashalofini noma emabhokisini, ambozwe 1/3 wokuphakama ngenhlabathi ekhanyayo enempilo. Izinga lokushisa elisendlini ligcinwa cishe ngo-20-25 ° C. Lapho ama-buds eqala ukukhula, ukuthambisa kuyanda, futhi izinga lokushisa liyancipha libe ngu-15-18 ° C. Ukusika kuthathwa ngemuva kwamasonto angama-3-4, kusuka ngasekupheleni kukaMashi kuya maphakathi noMeyi.
Ukwenza ngcono ukwakheka kwezimpande, izithasiselo ziyasetshenziswa, engisebenzisa kuzo usawoti we-potassium we-heteroauxin oncibilikisiwe emanzini. Ibola ngokushesha ekukhanyeni, ngakho-ke yonke imisebenzi yenziwa ngokukhanyiswa okuncane nasezitsheni ze-opaque.
Okokuqala, ama-200 g wefulawa yamalahle ayalungiswa futhi avinjelwe ngesihlungo esihle (0.5 mm). Ngemuva kwalokho ihlanganiswa nekhambi le-heteroauxin (1 g kasawoti we-potassium ngama-200 ml wamanzi eqhwa). I-100 g ye-potassium noma i-sodium humate, isixazululo se-ammonium molybdenum acid (5 g nge-100 ml yamanzi) no-50 g we-talc afakiwe kule ngxube. Zonke hlanganisa kahle. Ingxube ephumayo yomiswa ngaphandle kokufudumeza ebumnyameni futhi ichotshozwe ibe yimpuphu. Leli nani le-stimulator lanele ukucubungula izinkulungwane eziyishumi nanhlanu. I-Powder ithululelwa embizeni enesendlalelo esifinyelela ku-5 mm, ukuze isiqu sihlangane naso kuphela.
Njengoba ukusikeka kwe-dahlia kukhula hhayi kuphela entanjeni yezimpande, kodwa nakwi-tuber yezimpande, balungiselela ithuluzi lokusika elibukhali ngensimbi eqondile futhi egobile (kungenziwa ngama-halves of scissors curved kanye nama-tweezers). Ithuluzi elixegayo lizosonga izicubu zezitshalo, okuholele ekubolweni. Sika ukusikwa ngesithende. Lapho likhulu, yilapho ngempumelelo isitshalo siqala khona. Kodwa-ke, ngakolunye uhlangothi, ukwanda kwesithende kuholela ekunciphiseni kwenani lokusikwa okuvunwe, ngoba ama-buds okulala asikiwe kusuka kubhagi yezimpande, lapho amahlumela amasha azoqala ukukhula khona. Ngomsebenzi wokucophelela kusuka ku-tuber eyodwa yezimpande, ungavuka ukusikeka okungu-50. Ithuluzi kufanele lihlaselwe ngotshwala ngemuva kokuhlinzwa ngakunye.
Kumele kukhunjulwe ukuthi ukusetshenziswa kwama-hormone nobuchwepheshe obuqondile bokususa izisiki ngeke kulethe imiphumela elindelekile uma ngabe lolu hlobo olunamakhono aphansi lokwenza izimpande.
Ukuze kube nokubuna, ukusikwa kuthathwa isiqu saso singekho ngaphansi kwamamilimitha amathathu nobude obuyi-8-10 cm.Kusuka ezitshalweni ezincanyana kutholakala ukuthi ukuqhakaza sekwephuze kakhulu noma akunasikhathi sokuqhakaza. Eluhlaza okotshani, kungcono ukuthi ususe izihlahla ezisikiwe ekuseni kakhulu noma kusihlwa. Amahlumela kaDahlia anqunywa phakathi nesikhathi sasemini esivamile avame ukufa lapho umile. Lokhu kungachazwa iqiniso lokuthi ngaleso sikhathi abamba ukushisa kufudumeza kakhulu, umswakama womoya uyancipha, ukuhanjiswa kwamanzi ngamaqabunga kuyanda, kanti amahlumela asesimweni sokucindezelwa. (Kungasebenza okufanayo nokusika izimbali.) Imizuzu engu-15 ukuya kwengama-20 ngaphambi kokuba ukusikwa kusikwe, ama-tubers izimpande kufanele afafazwe ngamanzi, mhlawumbe iqhwa noma imvula, ukwandisa i-turgor kumaseli ezitshalo.
Ama-dahlia cuttings atshalwe emabhokisini athelwa kakhulu ngamanzi afudumele avela kumsele wokunisela ongashisi. Ebhokisini faka umaki nosuku lokusika. Izinsuku ezimbili ukusikeka kufanele kube sendaweni enomthunzi, khona-ke izinsuku ezingama-5 - ngaphansi kokukhanya okungahambi kahle. Futhi kuphela emva kwalokho bangakwazi ukuthola ukukhanya kwelanga, kepha hhayi amahora angaphezu kwama-8 ngosuku. Ngesikhathi sokukhula kwe-rooting, i-substrate kufanele ifudunyezwe.
Ukunisela ukusika kufanele kwenziwe ngesifutho sakusasa ekuseni nakusihlwa. Uma izinga lokushisa ku-greenhouse likhuphuka ngaphezu kwe-30 °, izitshalo zidinga ukufafazwa njalo. Ama-cutways anonile nganoma yisiphi isizathu kufanele asuswe ngokushesha.
I-midzi ye-dahlia ivela, ngokwesilinganiso, ngemuva kwezinsuku eziyi-10-15. Ukusuka emabhokisini, ukusikwa kutshalwe emabhodweni, kusuka kwizithombo zokugcina izithombo - emhlabathini ovulekile. Ngaphambi kokutshala, izitshalo kumele zenziwe lukhuni. Izithombo ezisikiwe ekuqaleni kukaJuni zitshalwe ngamaqembu noma imigqa kude ne-60-80 cm.
Root dahlia ekwindla ngemuva kwezimbali
Ama-mizizi we-dahlia izimpande zihlukaniswe maduzane ngaphambi kokutshala, zisika izingxenye ezimbili noma ezintathu ngommese obukhali ukuze uqhekeko ngalunye luqukethe ibhagi yezimpande nocezu lwentambo yempande enamehlo amabili noma amathathu. Konke ukusikeka kufafazwe ngamalahle ochotshoziwe ngesibabule (1: 1). Ukutshala endaweni kwenziwa ngasekupheleni kukaMeyi - ekuqaleni kukaJuni, ukujulisa intamo yezimpande ngo-3-5 cm (ukusika okugxilelwe ekhasini lokuqala lamaqabunga).
Izifo Nezinambuzane Dahlia
Ukwelashwa kokuvinjwa kwezilimo eziyizigaxa dahlia ezifweni nasezinambuzaneni
Ngemuva kwayo yonke imisebenzi, sekuyisikhathi sokwelapha ama-tubers ngama-fungicides (noma iyiphi i-fungic e-systemic noma isibabule ifanelekile). Ungafafaza amathiphu ama-tubers we-dahlia ngomuthi, noma ungawafafaza emanzini bese ucwilisa ngokuphelele zonke izimpande kwikhambi. Akekho oveze ukukhathazeka ukuthi ngesikhathi sokucwilisa ngokuphelele ukulandelana okugcwele kwama-tubers of dahlias esitsheni esifanayo, amagciwane angabhebhetheka.
Lapho ukhetha indlela ye-ukhunta ewuketshezi, gcina nezilimo eziyizigaxa kusisombululo cishe imizuzu eyi-15. Ngemuva kwale nqubo, udinga ukuwasula ngokuwabeka esisekelweni sokhuni, amakhadibhodi noma izingqimba eziningana zamaphephandaba (yenza le nqubo ngokulandelana, ngokusho kwamaqembu anhlobonhlobo ama-tubers, ukuze kube khona ithuba elincane lokudideka kwezinhlobo).
Musa ukomisa ama-tubers we-dahlia ezindaweni ezisetshenziswa ukhonkolo, njengoba basiza ukwelula umswakama kanye nezilimo eziyizigaxa ngaphambi kwesikhathi. Njalo ngelebuli enamagama ezinhlobonhlobo zaleli qembu lama-tubers eseseduze. Uma iziqukathi eziningana ezinesixazululo sezilungisiwe, beka ezizweni ngasinye zebanga elifanayo bese kuthi ukuma imizuzu eyi-15. Abanye abalimi bangeza izinambuzane ezihlelekile kusisombululo esilungiselelwe se-fungicide.
Ithiphu ebalulekile: lahla zonke izithombo zezilimo eziyizigaxa ze-dahlia, okuthi, lapho ucwiliswa, ungashisi, kepha zintantize ebusweni besixazululo - azisazukuhlala kuze kube yisizini ezayo.
Khumbula ukuthi zonke izinqubo ezinezilimo eziyizigaxa ezimanzi ngalesi sigaba somsebenzi ngamakhemikhali kumele zenziwe ngamagilavu enjoloba!
Ababhali abahlukahlukene batusa ukusuka kumizuzu eyi-15 kuye kwengama-30 yokucubungula ama-dahlia nezilimo eziyizigaxa. Futhi ochwepheshe abaningi ababoni ukuthi kungenzeka ukusebenzisa i-fungicides nhlobo. Mhlawumbe isimo sezulu sidlala indima ebusayo lapha: esimweni sezulu esimanzi sokukhula kwe-dahlias, amathuba okuba nezifo zokukhunta kuzo akhuphuke kunokuba omile.
Sucking futhi gnawing izinambuzane dahlia
Iqembu lokuqala lifaka izibuko zesicabucabu, ama-aphid, ama-greenhouse thrips, ama-penbies we-slobbery. Eminyakeni eyomile, ayingozi kakhulu. Ngaphezu kwalokho, ezinye izinambuzane zingabathwali be-dahlia mosaic mosaic, ngakho-ke ukusetshenziswa okufika ngesikhathi kwazo zonke izindlela zokuvimbela nokubhubhisa kuyisimo esidingekayo sesiko eliphumelelayo.
Isikhala sesicabucabu (Tetranychus urticae) ihlala ngaphansi kweqabunga, lapho yakha khona i-cobweb. Imikhaza yabantu abadala iphuzi elula noma eluhlaza okotshani, ubude obungu-0.3-0,5 mm. Ama-dahlias alimala akhombisa amaqabunga awayo noma amabala amhlophe qwa. Ukuhlobisa kwesitshalo kuyancishiswa, futhi esimweni sokutheleleka kanzima, kuyafa.
I-Aphids (Aphis fabae, Myzode Persicae) - izinambuzane ziyi-1.4-2.5 mm ubude, zimnyama (bean aphid) noma ngombala oluhlaza okotshani (greenhouse aphid). Yakha amakoloni amakhulu, abangele ukuvela kwamaqabunga, ukukhula okumangalisa nokuqhakaza, ukulahleka kokuhlobisa. Amaqabunga ambozwe ama-noshukela, lapho ukhula lwesikhunta lukhula khona.
I-Greenhouse thrips (Neliothrips haemorrhoidalis) nsundu omnyama, ubude obungu-1-1,5 mm, mncane ngomzimba, amaphiko angaphambili nemilenze iphuzi. Izibungu zimhlophe; zihlukile ezinambuzaneni ezindala ngosayizi omncane nokuntuleka kwamaphiko. Ama-safari ahlala ezinhlangothini zombili zamaqabunga amaqabunga, adla ngojusi weseli. Amaqabunga athola umchezeli wobisi, aphenduke ophuzi bese afa.
Amapeni we-Slobbering (Philaenus spumarius) uhlala kuma-axils amaqabunga kanye namahlumela. Izibungu zaso eziphuzi, ezakha amagwebu obuhlalu, ziyingozi. Kusukela ngasekupheleni kukaMeyi noJuni, balimaza amaqabunga angaphansi. Amahlamvu amaqabunga ancibilikile, embozwe amabala aphuzi; izikejana azivuthiwe.
Izinyathelo zokulawula ukunambitha izinambuzane: ukuqoqwa kanye nokubhujiswa kwemfucumfucu yezitshalo nokhula, ukumba ekwindla kwenhlabathi; ukufafaza ngolunye lwamalungiselelo - u-anti (0.1-0.2%), trichloromethaphosome-3, fosalone (0.2%), ikarbofos (0.2-0.3%), insipho eluhlaza (2%) noma ukumunca ugwayi (2%), yarrow (8%), ama-anyanisi husks (1/2 ibhakede layo ligcwele amanzi usuku).
Dahlias
Ngokuphikisana nethikhi, ungasebenzisa futhi i-celtan, uphondo (u-0,2%), ukumnika ugalikhi (2%), iziqalo zamazambane (10%), izitshalo zepovlinate ezinomkhuhlane wefiva. Ukusebenza kwezindlela zokwelapha kukhuphuka ngokufakwa kukamanyolo we-phosphorus ne-potassium (50 g we-potassium chloride noma i-sulfate no-100 g we-superphosphate nge-10 l yamanzi).
Ezinambuzaneni eziququda ze-dahlias, eziyingozi kakhulu ama-scoops - ilac, ipea, ingadi, kanye AmaNutcrackers kanye neKhrushchev.
Isikuni se-Purple (IHydroecia micacea) ilimaza isiqu - isibungu sayo esingu-30- 40 mm ubude sidla umongo okuso. Ngasikhathi sinye, amahlumela ayaphela, kuvame ukugqashuka. Ama-Butterflies abeka amaqanda ngeziqu zezitshalo.
Ingadi kanye nepea scoops (I-Polia oleracea, P. pisi) idla amaqabunga nezimbali ezinsundu. Pupae ubusika enhlabathini. Izimvemvane zindiza ngoJuni-Julayi, izinsikazi zibekela amaqanda izinqwaba ngezinqwaba.
Izinyathelo ezibhekiswe kuma-scoops: lapho kuvela amacimbi, izitshalo zifafazwa ngama-chlorophos, i-rotor, trichloromethaphos-3 (0.2%), carbophos (0.2-0.3%) noma i-entobacterin-3 (0.1-0.5%). Ukuze unamathele kangcono ubuthi, ukunamathisela kufakwa engxenyeni ngesilinganiso se-10 g ilitha elilodwa.
Ubulongwe obusha akufanele buthulwe ngaphansi kwe-dahlias; ezindaweni ezinjalo, izitshalo zonakaliswa kakhulu; lapho unciphisa umhlabathi, izitshalo mancane amathuba okutheleleka ngaleli gciwane.
I-earwig ejwayelekile (I-Forficula auricularia) i-resinous brown, umzimba ubude (kufika ku-20 mm). Kulimaza izitshalo ebusuku, kugaye izimbobo zamaqabunga, kudle amacembe ezimbali kanye namahlumela akhulayo. Isilonda esidonswa ngamehlo sitholakala ngoJulayi kuya kuSepthemba.
Izindlela zokulawula: ukumba okujulile kwenhlabathi ekwindla, kufafaza izitshalo nge-infusions kagalikhi nesikali sika-anyanisi. Ebusuku, ukuheha izinambuzane, beka izingidi zokudla otshanini, ngamapulangwe. Ntambama bayabhekelwa ngaphezulu kanti namawashi okugcina avikelekile ayabhujiswa.
Ama-tubers we-Dahlia nezimpande zivame ukonakala. izibungu zama-nutcrackers (ama-wireworms) namagilebhisi. Ngasikhathi sinye, izitshalo ezincane ziyafa, nabantu abadala basalele ekukhuleni; nezilimo eziyizigaxa zokubola.
I-nutcracker emnyama (i-Agriotes obscurus), i-nutcracker enemigqa (A. lineatus), i-nutcracker (A. sputator), i-nutcracker ebanzi (i-Selatosomus latus) ne-black nutcracker (i-Athous niger) zivame kakhulu. Umzimba wezibungu mncane, mude, uphuzi, noma onsundu; imilenze ye-pectoral imfushane, yobude obulingana. Amabhungane amnyama noma ansundu ngombala onsundu, abusika emhlabathini, kuthi ngoMeyi afike phezulu masinyane abeke amaqanda awo - ngamaqembu amancane angaphezulu kwenhlabathi. Izibungu zikhula iminyaka engama-3-4. Bancamela inhlabathi enomswakama, lapho kuqala isimo sezulu esomile bathuthela ezingxenyeni ezijulile.
I-Eastern May Khrushchev (Melolontha hippocastani) no NgoJuni khrushch (Amphimallon solstitialis) - izinambuzane eziyingozi i-dahlia. Izidwaba ezingama-40-45 mm ubude, zinomzimba ophuzi, zinekhanda elinsundu kanye nezinto zokusebenza zomlomo wokugedla ezakhiwe kahle. Zikhula kungakapheli iminyaka engama-3-5 - kuya ngohlobo lwe-cartilage, terrain kanye nezimo zezulu zonyaka.
Izindlela zokulawula ngokumelene ne-wireworms ne-khrushchev: ngokunisela inhlabathi nge-chlorophos engu-0,2 ngoMeyi-Juni, ekwindla ejulile ngokumba nge-12% uthuli lwe-HCCH (8 g / m2). Ukwenza imithamo emincane ye-HCH (1.5 kg / ha) engxenyeni ene-granular superphosphate, ukukhululwa okuvamisile, ukukhethwa kwebhukwana kanye nokubhujiswa kwezibungu kuyasebenza.
Ugogo wami ubesebenzelana nalezi zimbali isikhathi eside kakhulu. Lapho ufika kuye, izinhlobo eziningi zezimbali, izimbali, ukwakheka kwalesi sitshalo kungabonakala engadini yakhe ukuthi amehlo akhe ahlanekezelwe. Futhi ezindabeni zikamkhulu wami, ngibonile ukuthi lezi zimbali azithobeki neze, futhi uma ziqhakaza, khona-ke ngeke uthokoze ngale ngubo ekhanyayo yezimbali!
