Mafotokozedwe Akatundu

Paclobutrazol (PBZ) ndi mankhwala oletsa kutupa.Chowongolera Kukula kwa Zomerandi triazole Fungicide. Ndi mankhwala odziwika bwino otsutsana ndimahomoni a zomeragibberellin. Imagwira ntchito poletsa kupanga kwa gibberellin, kuchepetsa kukula kwa ma nodial kuti apereke tsinde lolimba, kukulitsa kukula kwa mizu, kuyambitsa zipatso zoyambirira komanso kuwonjezera kukula kwa mbewu m'zomera monga phwetekere ndi tsabola.

Kagwiritsidwe Ntchito

1. Kulima mbande zolimba mu mpunga: Nthawi yabwino kwambiri yopangira mankhwala a mpunga ndi tsamba limodzi, nthawi imodzi ya mtima, yomwe ndi masiku 5-7 mutabzala. Mlingo woyenera wa 15% paclobutrazol wonyowa ndi ma kilogalamu atatu pa hekitala ndi ma kilogalamu 1500 a madzi owonjezeredwa (monga magalamu 200 a paclobutrazol pa hekitala ndi ma kilogalamu 100 a madzi owonjezeredwa). Madzi m'munda wa mbande amauma, ndipo mbande zimapopedwa mofanana. Kuchuluka kwa 15% paclobutrazol ndi madzi ochulukirapo ka 500 (300ppm). Pambuyo pochiza, kuchuluka kwa mbewu kumachepa, zomwe zimapangitsa kuti kukula kukhale koyenera, kulimbikitsa kuphuka kwa mbande, kupewa kulephera kwa mbande, komanso kulimbitsa mbande.

2. Lima mbande zolimba m'magawo atatu a masamba a mbande za rape, gwiritsani ntchito 600-1200g ya ufa wonyowa wa paclobutrazol wa 15% pa hekitala, ndikuwonjezera 900kg ya madzi (100-200Chemicalbookppm) kuti mupopere tsinde ndi masamba a mbande za rape, kuti mulimbikitse kupanga chlorophyll, kupititsa patsogolo photosynthesis, kuchepetsa matenda a sclerotinia, kulimbitsa kukana, kuwonjezera nyemba ndi zipatso.

3. Pofuna kupewa kuti soya isakule mofulumira kuposa momwe imachitira poyamba, onjezerani magalamu 600-1200 a ufa wonyowa wa paclobutrazol wa 15% pa hekitala, 900 kg ya madzi (100-200 ppm), ndipo thirani madziwo pa tsinde ndi tsamba la mbande za soya kuti muwongolere kutalika kwake, kuwonjezera nyemba ndi zipatso.

4. Kuwongolera kukula kwa tirigu ndi kubzala mbewu ndi kuya koyenera kwa paclobutrazol kumakhala ndi mbande yamphamvu, kukulitsa kubzala, kuchepa kutalika, komanso kuchuluka kwa zokolola pa tirigu. Sakanizani magalamu 20 a ufa wonyowa wa paclobutrazol wa 15% ndi makilogalamu 50 a mbewu za tirigu (monga 60ppm), ndi kuchepetsa kutalika kwa chomera pafupifupi 5% mu Chemicalbook. Ndi yoyenera kubzala tirigu koyambirira ndi kuya kwa masentimita 2-3, ndipo iyenera kugwiritsidwa ntchito pamene ubwino wa mbewu, kukonzekera nthaka, ndi chinyezi zili bwino. Pakadali pano, kubzala pogwiritsa ntchito makina kumagwiritsidwa ntchito kwambiri popanga, ndipo kungakhudze kuchuluka kwa kumera pamene kuzama kwa kubzala kuli kovuta kuwongolera, kotero sikoyenera kuigwiritsa ntchito.
