Ⅰ. Imifuno
U-Epreli lixesha lentwasahlobo, kwaye ikwalixesha lokukhula kwezityalo ezininzi. Nangona kunjalo, intwasahlobo ikwalixesha lezinambuzane eziyingozi. Ngoko ke, izityalo ezininzi kufuneka zisebenzise izitshabalalisi ukulawula izinambuzane. Ngokomzekelo, imifuno efana nekhukhamba, ivatala, i-eggplant, kunye nepepile zisengozini kwizinambuzane ezifana ne-borers, i-leafhoppers enemibala kunye neempukane ezimhlophe ngexesha lokukhula. Ukukhusela ezi zityalo, ii-pesticides eziqulethe ulawulo oluchasene nezi zinambuzane, ezifana ne-cypermethrin, imidacloprid, njl.
Ngo-Epreli, izifo zemifuno kunye nezitshabalalisi ekumele kugxilwe kuzo ziquka ukungunda okungwevu, ukungunda okungwevu, intwala, i-diamondback moth, kunye nezinye izifo kunye nezinambuzane ezitshabalalisayo ziquka i-sclerotia, i-leaf miner, kunye ne-yellow stripe jump. Ngokubhekiselele kuthintelo kunye nolawulo, kufuneka sinikele ingqalelo ekuthinteleni izifo, kwaye sijonge kwangexesha kwaye siphathe izinambuzane zezinambuzane ukuqinisekisa ukukhula okuqhelekileyo kwemifuno kwintsimi entwasahlobo.
Ukwenzeka kwezifo eziphambili kunye nezinambuzane kunye neengcebiso zokulawula amayeza.
(1) Ukungunda okungwevu: Esi sifo sesona sifo siphambili kwiitumato zasekuhlaleni yaye siya kungena encotsheni yenqanaba phakathi kuAprili. Ngaphambi kokuqala kwekhukhamba, i-manganese zinc (M-45) ingasetyenziselwa ukuthintela ikhukhamba, kwaye kwinqanaba elilandelayo, i-graft (ukukhawuleza), i-anisoclurea (buhein), i-pyrimethamycin, i-diacilamide, i-pyritocycloisocourea, kunye nezinye ii-agent zingasetyenziswa. .
(2) Isifo se-Downy mildew: Esi sifo sisifo esiqhelekileyo kwi-lettuce yasentwasahlobo yasekuhlaleni, isipinatshi, ivatala. I-melon yokutyala kwangethuba (ikhukhamba) iya kungena kwixesha eliphakamileyo lokukhula ngasekupheleni kuka-Epreli. Inokukhetha i-cream, i-manganese zinc, i-frost urea, i-manganese zinc, i-zinc ye-frost manganese engendawo, i-enolymorpholine, i-frost mildew, kunye nezinye ii-arhente.
(3) Iintwala ziyingozi kakhulu kwiimbotyi, icruciferous, isolanum, ivatala kunye neminye imifuno. Ngolawulo lwakutsha nje, iintwala ziphantsi kolawulo olusebenzayo. Inokukhetha i-amidine, imidacloprid, i-amine, kunye nezinye ii-agent, kwaye iphathe imifuno yeziqhamo i-lacia tabaci.
(4) Inundu le-Diamondback: Ngokohlolisiso, i-cauliflower kumasimi ali-13 yayinomlinganiselo wezityalo ezili-12.6 ukuya kwezili-100, ezinoluhlu lweentloko eziyi-0-100, ingakumbi imibungu eselula entsimini. I-Abamectin, iivithamini, i-acitral, i-ethyl polybiocidin, i-thuringiensis, kunye namanye ama-agent anokukhethwa.
(5) Ezinye izifo nezinambuzane: Isifo seFusarium wilt sinokunyangwa ngeRotmilben, isobacterium urea, acinamide, methylsulfur bacterium agent. Abavukuzi bamagqabi banokunyangwa nge-avermectin, i-phoxim, kunye nezinye ii-agent. Unyango lomhlaba lokutsiba kwemigca etyheli lunokusetyenziswa ukulawula imibungu. Kwinqanaba lezithole, linokusetyenziswa, kwinqanaba lokugqibela lokukhula, i-fluoride ephezulu (i-arica), i-fluoride ephezulu (i-fuqi), i-benzamide, kunye nezinye i-agent zingasetyenziselwa ukulawula. Kwimeko yeziganeko ezixubileyo zezifo ezahlukahlukeneyo kunye nezinambuzane zezinambuzane, ii-agent ezijoliswe kuzo zingasetyenziswa kunye.
Imiba kunye neengqalelo
Ukusetyenziswa ngokuqhubekayo kwe-arhente efanayo; musa ukwandisa ukusetyenziswa kwezibulali zinambuzane; yeka amayeza kwiintsuku ezisi-7 ukuya kwezi-10 phambi kokuvuna ukuthintela iintsalela zezibulali-zinambuzane ezigqithisileyo.
Ixesha lokuposa: Mar-30-2023
