I-Brassinolide ibonwa njenge-hormone yesikhashana yesithupha kunazo zonke emhlabeni. Inemisebenzi yokukhuthaza ukukhula, ukukhuthaza izimpande endaweni yokutshala, ngcono ukumelana nokucindezela, ukwandisa isivuno kanye nekhwalithi, umphumela we-synergistic futhi uqede i-phytotoxicity. Kusetshenziswa kabanzi emafutheni nakunhlamvu. Izilimo, izihlahla zezithelo, imifino kanye nezinye izilimo eziningi ezinkulu.
I-24-hybrid epibrassinolide (cishe i-60% -70% ingama-22, 23, ama-epibrassinolide angama-30, ama-epibrassinolide angama-24-epibrassinolide, ama-28-epihrassinolide, ama-28-homobrassiwolide, 14-hydroxybrassinoltel.
Njengamanje, yi-14-hydroxy brassinostellol kuphela, i-compact ebizwa nge-rapeed brassinolide, kepha abacwaningi abavela eMnyangweni Wezolimo Abahlangene bachitha iminyaka engu-225kg yokukhishwa ngo-10 mg kuphela amasampula akhishwe empondweni. Ngokwesibalo esinengqondo, cishe ama-100,000 mu wezimbali ze-rapseed angakhipha kuphela ama-27 mg (ie 0.027 g) we-brassinolide yemvelo emsulwa.
Yize i-Brassinolide inezinhlobonhlobo zezicelo, cishe zonke izilimo zingasetshenziswa; kusuka imbewu efakwe ekubuyiselweni kombuso wesihlahla ngemuva kokuvunwa, yonke inqubo yokukhula kwezitshalo ingasetshenziswa; Izindlela ezahlukahlukene zokusebenzisa, njengokugqoka kwembewu, imbewu yokufaka, ukuchelela ukudonsa, ukufafaza izimpande, isifutho seqabunga, ukufafaza amaqabunga ukuze u-navigation Spray, njll; Ukusebenza kahle okuphelele, ukuxubana okulula, uhla lokuhlushwa kwesicelo olubanzi, olwaziwa ngokuthi "Panacea".
Kodwa-ke, kulezi zimo, i- "Panacea" Brassin kumele ikhutshazwe
1. Kwenqatshelwe ukuxuba nama-alkaline ama-pesticides kanye nomanyolo
I-Brassin lactone akufanele ihlanganiswe nomanyolo we-alkaline: Umanyolo we-calcium magnesium phosphate, i-ammonium bicarbobonate, i-amonium nittarate, i-amordeaux, njll. Ingxube linda, ngaphandle kwalokho kungahle kube nomonakalo wezidakamizwa.
2. Ungahlanganisi nama-herbicides
I-Brassin ingadambisa i-phytotoxicity of herbicides. Uma ukhula lumunca i-Brassin, umphumela we-herbicidal uzoncishiswa. Kunconywa ukusebenzisa lezi ezimbili ngesikhathi sokuphumula kwezinsuku ezingaphezu kuka-7.
3. Ungafaki i-Brassun kwiziza eziphumelelayo
I-Brassin ingakhuthaza ukwahlukaniswa kwamangqamuzana esitshalweni futhi inomphumela wokukhuthaza ukukhula. Kodwa-ke, lapho kunesakhiwo esichumayo, kuyadingeka ukulawula ukuchuma ngokushesha okukhulu, kunokuba kufafaze i-Brassin.
I-4. Ungafaki i-Brassin ngezinsuku zemvula noma lapho kunemvula kungakapheli amahora ayi-6
Ngemuva kokuthi i-Brassin ifafazwe emaqabungeni ezilimo, izothatha isikhathi esithile ukudonswa yizilimo. Uma lina lina, imvula izogeza uketshezi lwezokwelapha, ngasikhathi sinye, luzophinda ilunciphise ukugxila okuthile, okuphumela emphumeleni omkhulu we-brassin. Phansi, ngakho-ke bukela isimo sezulu kusenesikhathi lapho ufafaza i-Brassin.
I-5. I-Brassinolide ayikwazi ukusetshenziswa ekushiseni okuphezulu
Ukufafaza kwe-Brassin akufanele kwenziwe ntambama, okungukuthi, lapho izinga lokushisa liphezulu kakhulu. Ngalesi sikhathi, indawo yamaqabunga ivele ngokushesha. Okokuqala, akulula ngezilimo ukuze zizithobe. Ngasikhathi sinye, ukuvikela ukuhwamuka ngokushesha kwamanzi ngamazinga aphezulu futhi kwandise ukugcwala kwesixazululo sase-Brassin.
I-6. Ungasebenzisi ekugxilweni okuphezulu
I-Brassinolide yinto yamakhemikhali enesakhiwo se-biomimetic sterol. Inokuhlushwa okuthile okulungele ukusetshenziswa. Uma ukugxila kuphezulu kakhulu, ngeke kudale imfucuza, kepha kungavimba nezilimo ngamazinga ahlukahlukene.
7. I-Brassinolide akuyona umanyolo we-foliar
I-Brassinolide inguMlawuli Wokukhula Kwesitshalo, osesigabeni sama-pesticides, hhayi umanyolo wefoliya. I-Brassinolide ngokwayo ayinawo umsoco. Ilawula ngokungaqondile ukukhula kwezilimo ngokulawula uhlelo lwe-hormone ephelele yesitshalo, elifana kakhulu nomanyolo wefoliya. Ukuhambisana okuhle, kepha i-Brassinolide uqobo ayinazo izakhamzimba, ngakho-ke kuyadingeka ukuqinisekisa ukunikezwa kwezakhi zomzimba, kanye nokuhlanganiswa kwe- "amanzi, umanyolo kanye nokulungiswa", ukuze i-Brassinololide ngidlale indima engcono esitshalweni.
