Urutonde rw'ibiciro bihendutse rw'igenzura ry'imiti ikomoka ku buhinzi Auxin 6-Ba 98% Tc

Paclobutrazol (PBZ) ni ubwoko bwaIbipimo by'Imikurire y'IbimeranaUdukoko two mu bwoko bwa fungi.Ni ikintu kizwiho kuba gibberellin, imisemburo y'ibimera.Bibuza gukora gibberellin, bigabanya gukura kw'amanodi kugira ngo ibiti bibe birebire, byongera imikurire y'imizi, bigatera imbuto zitangira gukwirakwira no kwiyongera kw'imbuto mu bimera nk'inyanya na puwavuro. PBZ ikoreshwa n'abahanga mu by'ibiti mu kugabanya imikurire y'ibiti kandi byagaragaye ko igira ingaruka nziza ku biti n'ibihuru.Muri ibyo harimo kwiyongera k’ubudahangarwa bw’amapfa, amababi y’icyatsi kibisi cyijimye, kwiyongera k’ubudahangarwa bw’ibihumyo na bagiteri, ndetse no kwiyongera k’imizi.Gukura kwa Cambial, kimwe n'ikura ry'imishishwa, byagaragaye ko bigabanuka mu moko amwe n'amwe y'ibiti. Byagize ingaruka Nta burozi ku nyamaswa z'inyamabere.

Imikoreshereze

1. Guhinga ingemwe zikomeye mu muceri: Igihe cyiza cyo kuvura umuceri ni ikibabi kimwe, igihe cy'umutima umwe, kikaba nyuma y'iminsi 5-7 nyuma yo kubiba. Igipimo gikwiye cyo gukoresha ni 15% by'ifu ya paclobutrazol, hamwe na kilogarama 3 kuri hegitari n'ibiro 1500 by'amazi byongewemo.

Kurinda ko umuceri ukomeza gukwirakwira: Mu gihe cyo guteranya umuceri (iminsi 30 mbere yo gutera umuceri), koresha ibiro 1.8 by'ifu ya paclobutrazole 15% kuri hegitari imwe na kilo 900 z'amazi.

2. Hinga imbuto zikomeye z'imbuto za rapeseed mu gihe cy'amababi atatu, ukoresheje garama 600-1200 z'ifu ya paclobutrazole 15% kuri hegitari imwe na kilogarama 900 z'amazi.

3. Kugira ngo wirinde ko soya ikura cyane mu gihe cyo gutangira kurabya, koresha garama 600-1200 z'ifu ya paclobutrazole 15% kuri hegitari imwe hanyuma wongeremo ibiro 900 by'amazi.

4. Kugenzura imikurire y'ingano no kuziba imbuto hamwe n'ubujyakuzimu bukwiye bwa paclobutrazol bitera imbuto zikomeye, zitera neza, uburebure buke, kandi umusaruro wiyongera ku ngano.

Ibitekerezo

1. Paclobutrazol ni umuti ukomeye ubuza gukura, umara igihe kingana n'imyaka 0.5-1.0 mu butaka mu bihe bisanzwe, kandi ukaba umara igihe kirekire utera ingaruka. Nyuma yo gutera mu murima cyangwa mu gihe cy'imbuto z'imboga, akenshi bigira ingaruka ku mikurire y'ibihingwa bikurikira.

2. Genzura neza urugero rw'umuti. Nubwo urugero rw'umuti rurushaho kuba rwinshi, niko ingaruka zo kugenzura uburebure zirushaho gukomera, ariko no gukura kuragabanuka. Iyo gukura gutinze nyuma yo kugenzura cyane, kandi ingaruka zo kugenzura uburebure zidashobora kugerwaho ku rugero ruto, hagomba gushyirwaho ingano ikwiye y'umuti ku buryo bungana.

3. Kugenzura uburebure n'ingano y'umuceri bigabanuka uko ingano y'umuceri wo mu bwoko bwa hybride late river izamuka, kandi ingano y'umuceri wo mu bwoko bwa hybride late river ntirenga ibiro 450 kuri hegitari. Gukoresha ingano y'umuceri mu gusimbuza imbuto bishingiye ku gutera bike. Irinde kuzura no gukoresha ifumbire ya azote cyane nyuma yo kuyikoresha.

4. Ingaruka zo gukura za paclobutrazol, gibberellin, na aside indoleacetic zigira ingaruka zo gukumira. Iyo ingano ari nyinshi cyane kandi ingemwe zikabuzwa cyane, ifumbire ya azote cyangwa gibberellin ishobora kongerwamo kugira ngo itabarwe.

5. Ingaruka za paclobutrazol ku moko atandukanye y'umuceri n'ingano ziratandukanye. Mu kuyikoresha, ni ngombwa kongera cyangwa kugabanya urugero rw'umuti mu buryo bworoshye, kandi uburyo bwo kuvura ubutaka ntibugomba gukoreshwa.
