Paclobutrazol muri rusange ni ifu, ishobora kwinjizwa mu giti binyuze mu mizi, ibiti n'amababi y'ibiti by'imbuto bitewe n'amazi, kandi bigomba gukoreshwa mu gihe cy'ihinga. Mubusanzwe hariho uburyo bubiri: gukwirakwiza ubutaka no gutera amababi.
1. Yashyinguwe paclobutrazol
Igihe cyiza nigihe isasu rya kabiri rirasa kuri cm 3-5 (iyo umuhondo uhindutse icyatsi cyangwa mbere yicyatsi kibisi). Ukurikije ingano yikamba, ubwoko butandukanye, nubutaka butandukanye, hakoreshwa urugero rutandukanye rwa paclobutrazol.
Muri rusange, ibicuruzwa bya paclobutrazol bikoreshwa kuri metero kare yikamba ya 6-9 g, umwobo cyangwa umwobo wimpeta ufungurwa cm 30-40 mumurongo wigitonyanga cyangwa cm 60-70 uvuye kumutwe wigiti, hanyuma ugatwikirwa nubutaka. nyuma yo kuvomera. Niba ikirere cyumye, Gupfuka ubutaka nyuma yo kuvomera neza.
Gukoresha paclobutrazol ntibigomba kuba kare cyane cyangwa bitinze. Igihe cyihariye kijyanye nubwoko butandukanye. Kera cyane bizagushikana byoroshye kurasa no guhinduka; bitinze cyane, amafuti ya kabiri azoherezwa mbere yuko ishoti rya gatatu rihinduka icyatsi. .
Ubutaka butandukanye nabwo buzagira ingaruka kumikoreshereze ya paclobutrazol. Muri rusange, ubutaka bwumucanga bugira ingaruka nziza zo gushyingura kuruta ubutaka bwibumba. Birasabwa gukoresha paclobutrazol mumirima imwe n'imwe ifite ubutaka bwinshi.
2. Gutera amababi ya paclobutrazol kugirango ugenzure imishitsi
Imiti ya paclobutrazol foliar igira ingaruka yoroshye kurusha iyindi miti, kandi irashobora kugabanya neza ibyangiritse ku giti mugihe cyo kugenzura kurasa. Mubisanzwe, iyo amababi ahindutse icyatsi kandi akaba adakuze bihagije, koresha paclobutrazol 15% yifu ya wettable kunshuro yambere inshuro zigera kuri 600, hanyuma wongere buhoro buhoro ingano ya paclobutrazol 15% yifu ya kabiri. Igenzura kurasa rimwe muminsi -10. Nyuma yo kugenzura imishitsi inshuro 1-2, imishitsi itangira gukura. Menya ko amashami adakuze neza, mubisanzwe ntukongereho ethephon, naho ubundi biroroshye gutera amababi kugwa.
Iyo amababi ahindutse icyatsi, abahinzi b'imbuto bamwe bakoresha paclobutrazol kugirango babanze bagenzure neza. Igipimo ni garama 1400 hamwe na kg 450 y'amazi. Igenzura rya kabiri ryamasasu mubyukuri ni kimwe nicyambere. Igipimo kizagabanuka nyuma kugeza kigeze kuri 400. Hamwe na ml 250 ya ethephon. Iyo ubanza kugenzura imishitsi, ibintu bisanzwe ni ukugenzura rimwe muminsi irindwi, ariko imvugo yizuba cyangwa izindi mpamvu zigomba gusuzumwa. Nyuma yo gushikama kugenzurwa, irashobora kugenzurwa rimwe muminsi icumi.
