Kushandiswa

1. Kurima mbesa dzakasimba mumupunga: Nguva yakanakisisa yemupunga ishizha rimwe chete, nguva yemwoyo mumwe, inova mazuva mashanu kusvika manomwe mushure mekudyara. Chiyero chakakodzera chekushandisa i15% paclobutrazol wettable powder, ine makirogiramu matatu pahekita uye makirogiramu zana nemazana mashanu emvura anowedzerwa.

Kudzivirira mupunga kuti usapinda mupunga: Munguva yekusangana kwemupunga (mazuva makumi matatu usati watanga kukanda mupunga), shandisa makirogiramu 1.8 e15% paclobutrazol wettable powder pahekita imwe neimwe uye makirogiramu 900 emvura.

2. Kurima mbesa dzakasimba dzerapeseed panguva yemashizha matatu, uchishandisa magiramu 600-1200 e15% paclobutrazol wettable powder pahekita imwe neimwe uye makirogiramu 900 emvura.

3. Kuti soyabhinzi dzisakure zvakanyanya panguva yekutanga kutumbuka, shandisa magiramu 600-1200 e15% paclobutrazol wettable powder pahekita imwe neimwe wobva wawedzera makirogiramu 900 emvura.

4. Kudzora kukura kwegorosi uye kudiridza mbeu nepaclobutrazol yakadzika zvakakwana zvine mhodzi yakasimba, kurima kwakawedzera, kureba kwakaderera, uye goho rakawanda pagorosi.

Kutariswa

1. Paclobutrazol inodzivirira kukura kwezvirimwa zvine hafu yehupenyu hwemakore 0.5-1.0 muvhu mumamiriro ezvinhu akajairwa, uye nguva yakareba yekusashanda kwayo. Mushure mekupfapfaidza mumunda kana muchikamu chekumera kwembeu yemuriwo, inowanzo kukanganisa kukura kwezvirimwa zvinotevera.

2. Kunyatso tarisa huwandu hwemushonga. Kunyangwe huwandu hwemushonga hwakakwira, simba rekutonga kureba rinosimbawo, asi kukura kunodererawo. Kana kukura kwacho kuchinonoka mushure mekudzora zvakanyanya, uye simba rekutonga kureba risingakwanise kuwanikwa nechiyero chidiki, huwandu hwakakodzera hwemushonga hunofanira kuiswa zvakaenzana.

3. Kudzora kureba uye kurima kunoderera nekuwedzera kwehuwandu hwekudyara, uye huwandu hwekudyara hwemupunga wehybrid late haupfuure 450 kg/hectare. Kushandisa matiller kutsiva mbesa kunobva pakudyara kushoma. Dzivisa kuzara kwemvura uye kushandisa fetereza yenitrogen zvakanyanya mushure mekushandisa.

4. Kukura kwepaclobutrazol, gibberellin, uye indoleacetic acid kunobatsira pakukura kwezvirimwa. Kana mbesa dzacho dzakanyanya kudziviswa uye dzisisadiwi zvakanyanya, nitrogen fertilizer kana gibberellin zvinogona kuwedzerwa kuti zvisapararire.

5. Kukanganisa kwepaclobutrazol pamhando dzakasiyana dzemupunga negorosi kunosiyana. Pakushandisa, zvakakosha kuwedzera kana kuderedza dose nenzira yakakodzera, uye nzira yekurapa ivhu haifanirwe kushandiswa.
