Agriculture Chemical Plant Growth Hormone Paclobutrazol

Paclobutrazol(PBZ) ndiWowongolera Kukula kwa Zomerandi triazoleFungicide. Ndiwotsutsa wodziwika wa hormone ya zomera gibberellin. Zimagwira ntchito poletsa gibberellin biosynthesis, kuchepetsa kukula kwa internodial kuti apereke tsinde, kuwonjezera kukula kwa mizu, kuchititsa zipatso zoyamba komanso kukula kwa mbewu muzomera monga phwetekere ndi tsabola.

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 wa 15% paclobutrazol ufa wonyowa ndi 3 kilogalamu pa hekitala ndi 1500 kilogalamu ya madzi owonjezera (ie 200 magalamu a paclobutrazol pa hekitala ndi 100 kilogalamu ya madzi owonjezera). Madzi a m’munda wa mbande amauma, ndipo mbande zimathiridwa mofanana. Chiwerengero cha 15%paclobutrazolndi 500 nthawi zamadzimadzi (300ppm). Pambuyo pa chithandizo, kukula kwa mbewu kumachepa, kumabweretsa zotsatira zowongolera kukula, kulimbikitsa kulima, kupewa kulephera kwa mbande, ndikulimbitsa mbande.

2. Limani mbande zolimba pamasamba atatu a mbande zogwiriridwa, gwiritsani ntchito 600-1200g ya 15% paclobutrazol wettable ufa pa hekitala, ndi kuwonjezera 900kg madzi (100-200Chemicalbookppm) kupopera mbewuzo ndi masamba a mbande zogwiririra, kulimbikitsa mbande zogwiririra, kuchepetsa kugwiririra mbande, kupititsa patsogolo kugwiririra mbande. sclerotinia, onjezerani kukana, kuonjezera makoko ndi zokolola.

3. Pofuna kupewa soya kukula msanga kusiyana ndi nthawi yoyamba maluwa, 600-1200 magalamu a 15% paclobutrazol wettable ufa pa hekitala, 900 kg ya madzi (100-200 ppm), ndi madzi kupopera tsinde ndi tsamba la soya mbande kulamulira kutalika ndi zokolola.

4. Kukula kwa tirigu ndi kuthirira mbewu mozama moyenereraPaclobutrazolkukhala ndi mbande yolimba, kukulitsa kulima, kuchepetsa kutalika, komanso kuchulukitsa zokolola za tirigu. Sakanizani 20 magalamu a 15% paclobutrazol ufa wonyowa ndi ma kilogalamu 50 ambewu ya tirigu (ie 60ppm), ndi kuchepetsa kutalika kwa mbewu pafupifupi 5% mu Chemicalbook. Ndioyenera kufesa msanga m'minda ya tirigu ndi kuya kwa 2-3 centimita, ndipo iyenera kugwiritsidwa ntchito pamene ubwino wa mbewu, kukonza nthaka, ndi chinyezi zili bwino. Pakalipano, kufesa kwa makina kumagwiritsidwa ntchito kwambiri popanga, ndipo kungakhudze momwe zimamera pamene kuya kwake kumakhala kovuta kulamulira, kotero sikuli koyenera kuzigwiritsa ntchito.
