CAS 76738-62-0 Zowongolera Kukula kwa Zomera Paclobutrazol
Paclobutrazol ndi wa azolechomeraZowongolera Kukula.Ndi mtundu wa biosynthetic inhibitors wa endogenous gibberellin.Imakhala ndi zotsatira zolepheretsakukula kwa zomerandi kufupikitsa mawu.Amagwiritsidwa ntchito mu mpunga kuti apititse patsogolo ntchito ya indoleAcetic Acidoxidase, kuchepetsa mlingo wa amkati IAA mu mbande mpunga, kwambiri kulamulira mlingo wa kukula pamwamba pa mbande mpunga, kulimbikitsa tsamba, kupanga masamba mdima wobiriwira, mizu anayamba, kuchepetsa malo ogona ndi kuonjezera kupanga kuchuluka.
Kugwiritsa ntchito
1. Kulima mbande zolimba mumpunga: Nthawi yabwino ya mankhwala a mpunga ndi tsamba limodzi, nthawi ya mtima umodzi, yomwe ndi masiku 5-7 mutabzala.Mlingo woyenera wogwiritsira ntchito ndi 15% paclobutrazol wettable ufa, ndi 3 kilogalamu pa hekitala ndi 1500 kilogalamu ya madzi anawonjezera.
Kupewa malo ogona mpunga: Pa nthawi yophatikizira mpunga (masiku 30 musanafike), gwiritsani ntchito ma kilogalamu 1.8 a 15% paclobutrazol ufa wonyowa pa hekitala ndi ma kilogalamu 900 amadzi.
2. Limani mbande zolimba za rapeseed pamasamba atatu, pogwiritsa ntchito 600-1200 magalamu a 15% paclobutrazol ufa wonyowa pa hekitala ndi ma kilogalamu 900 a madzi.
3. Pofuna kupewa soya kuti asakule mopambanitsa pa nthawi ya maluwa oyamba, gwiritsani ntchito magalamu 600-1200 a 15% paclobutrazol ufa wonyowa pa hekitala ndikuwonjezera ma kilogalamu 900 a madzi.
4. Kuwongolera kakulidwe ka tirigu ndi kuvala kwa mbeu zokhala ndi kuya koyenera kwa paclobutrazol zimakhala ndi mbande zolimba, zolima mochulukira, kuchepa kutalika, komanso kuchuluka kwa zokolola za tirigu.
Kusamala
1. Paclobutrazol ndi cholepheretsa kukula kwamphamvu ndi theka la moyo wa zaka 0.5-1.0 m'nthaka pansi pazikhalidwe zabwino, komanso nthawi yayitali yotsalira.Pambuyo kupopera mbewu mankhwalawa m'munda kapena mbande zamasamba, nthawi zambiri zimakhudza kukula kwa mbewu.
2. Yang'anirani kwambiri mlingo wa mankhwala.Ngakhale apamwamba ndende ya mankhwala, mphamvu zotsatira za ulamuliro kutalika ndi, koma kukula amachepetsa.Ngati kukula kuli pang'onopang'ono pambuyo pa kulamulira mopitirira muyeso, ndipo zotsatira za kuwongolera kutalika sizingatheke pa mlingo wochepa, mlingo woyenera wa kupopera uyenera kuikidwa mofanana.
3. Kuwongolera kutalika ndi kulima kumachepa ndi kuchuluka kwa kubzala, ndipo kufesa kwa mpunga wochedwa wosakanizidwa sikudutsa ma kilogalamu 450 pa hekitala.Kugwiritsa ntchito tiller m'malo mwa mbande kumatengera kufesa pang'ono.Pewani kusefukira kwa madzi ndi kuthira feteleza wa nayitrogeni mopitirira muyeso mutatha kugwiritsa ntchito.
4. Kukula kolimbikitsa mphamvu ya paclobutrazol, gibberellin, ndi indoleacetic acid kumakhala ndi kutsekereza kotsutsa.Ngati mlingo uli wochuluka kwambiri ndipo mbande zaletsedwa kwambiri, feteleza wa nayitrogeni kapena gibberellin akhoza kuwonjezeredwa kuti apulumutse.
5. The dwarfing zotsatira za paclobutrazol pa zosiyanasiyana mpunga ndi tirigu zimasiyanasiyana.Mukamagwiritsa ntchito, ndikofunikira kuti muwonjezere kapena kuchepetsa mlingo moyenera, ndipo njira yamankhwala ya dothi sayenera kugwiritsidwa ntchito.
