Ubuhinzi: Imisemburo yo gukura kw'ibimera bya "chemical" Paclobutrazol 15% WP 20% WP 25% WP
Paclobutrazol(PBZ) niIbipimo by'Imikurire y'Ibimerana triazoleUdukoko two mu bwoko bwa fungiNi ikintu kizwiho kurwanya imisemburo y’ibimera yitwa gibberellin. Ikora mu kubuza imikorere ya gibberellin, ikagabanya gukura kw’amanodi kugira ngo itange amashami maremare, yongera imikurire y’imizi, igatera imbuto zitangira gukwirakwira no kwiyongera kw’imbuto mu bimera nk’inyanya n’urusenda.
Imikoreshereze
1. Guhinga ingemwe zikomeye mu muceri: Igihe cyiza cyo kuvura umuceri ni ikibabi kimwe, igihe cy'umutima umwe, ni iminsi 5-7 nyuma yo gutera. Igipimo gikwiye cya 15% by'ifu ya paclobutrazol itose ni ibiro 3 kuri hegitari hamwe na kilogarama 1500 z'amazi yongewemo (ni ukuvuga garama 200 za paclobutrazol kuri hegitari hamwe na kilogarama 100 z'amazi yongewemo). Amazi ari mu murima w'ingemwe yumye, kandi ingemwe ziterwa ku buryo bungana. Igipimo cya 15%paklobutrazoleni inshuro 500 z'amazi (300ppm). Nyuma yo kuvurwa, igipimo cyo kurekura kw'ibimera kiragabanuka, bigatanga ingaruka zo kugenzura imikurire, guteza imbere guhinga, gukumira kwangirika kw'ibimera, no gukomeza ingemwe.
2. Hinga ingemwe zikomeye mu cyiciro cy'amababi atatu y'ingemwe za rape, koresha garama 600-1200 z'ifu ya paclobutrazole 15% kuri hegitari, wongereho 900kg z'amazi (100-200Chemicalbookppm) kugira ngo utere amashami n'amababi y'ingemwe za rape, uteze imbere imikorere ya chlorophyll, wongere umuvuduko wa photosynthesis, ugabanye indwara ya sclerotinia, wongere ubushobozi bwo kurwanya, wongere ibishishwa n'umusaruro.
3. Kugira ngo hirindwe ko soya idakura vuba kurusha uko yabanje kurabya, garama 600-1200 z'ifu ya paclobutrazole 15% kuri hegitari, kg 900 z'amazi (100-200 ppm), hanyuma ushyiremo amazi ku giti n'ikibabi cy'imbuto za soya kugira ngo ugenzure uburebure, wongere ibishishwa n'umusaruro.
4. Kugenzura imikurire y'ingano no gutunganya imbuto hamwe n'ubujyakuzimu bukwiye bwaPaclobutrazolIfite ingemwe zikomeye, ihinga neza, uburebure buke, kandi umusaruro wiyongera ku ngano. Vanga garama 20 z'ifu y'ingano ya paclobutrazole ya 15% hamwe na kilogarama 50 z'imbuto z'ingano (ni ukuvuga 60ppm), hamwe n'igipimo cyo kugabanya uburebure bw'ibimera cya 5% muri Chemicalbook. Ikwiriye mu mirima y'ingano iterwa hakiri kare ifite ubujyakuzimu bwa santimetero 2-3, kandi igomba gukoreshwa iyo ubwiza bw'imbuto, itegurwa ry'ubutaka, n'ubushuhe ari byiza. Muri iki gihe, gutera imashini bikoreshwa cyane mu musaruro, kandi bishobora kugira ingaruka ku gipimo cyo kumera iyo uburebure bw'imbuto bugoye kugenzura, bityo ntibikwiriye kuyikoresha.
