Ibanga Lobuchwepheshe: 98%TC

Izidingo zobuchwepheshe zokusetshenziswa:

1. Lawula ngokuqinile isikhathi sokufaka isicelo kanye nomthamo.Esigabeni sokuhlakula ukolweni, akufanele kusetshenziswe ngaphambi kwesikhathi (ngaphambi kwamaqabunga ama-4) noma sekwephuzile (ngemuva kokuhlanganisa).Ukhula olukhulu olunamaqabunga abanzi (3-5) ensimini kufanele lusetshenziswe esigabeni samaqabunga, ukugwema izinga lokushisa eliphansi kanye nezinsuku ezomile.Qaphela ukuzwela kwezinhlobonhlobo zikakolweni.

2. Lo mkhiqizo uzwela kakhulu ezitshalweni ezinamahlamvu abanzi njengokotini, ubhontshisi wesoya, i-rapeseed, ubhekilanga kanye nekhabe.Lapho ufutha, kufanele kwenziwe esimweni sezulu esingenamoya noma esinomoya.Ungafafazi noma ukhukhuleke ezitshalweni ezizwelayo ukuze ugweme i-phytotoxicity.Le ejenti akufanele isetshenziswe emasimini anezitshalo ezinamahlamvu abanzi.

3. Ungasifaki isicelo ngezinsuku ezinomoya noma lapho kulindeleke ukuthi line.

4. Izitshalo kufanele zisetshenziswe kakhulu kanye ngesizini, futhi isicelo kufanele sihambisane ngokuqinile nezinqubo zokusebenza.Isicelo akufanele sisheshe kakhulu noma sephuze kakhulu;izinga lokushisa akufanele libe liphansi kakhulu noma libe phezulu kakhulu ngesikhathi sokufakwa (izinga lokushisa elilungile liyi-15℃～28℃).

Imiyalelo:

1.Ukuhlakula emasimini kakolweni wasebusika kanye namasimu ebhali asebusika: kusukela ekupheleni kokulinywa kuze kufike esigabeni sokuhlanganisa ukolweni noma ibhali, esigabeni samaqabunga ama-3-5 okhula, sebenzisa u-72% SL 750-900 ml ihektha ngalinye, 40-50 kg wamanzi, kanye no-40-50 kg wamanzi ehektheleni.Isifutho seqabunga lesiqu sotshani.

2.Ukukhipha ukhula emasimini ommbila: esigabeni samaqabunga angu-4-6 we-Wang Mi, sebenzisa u-600-750 ml we-72% SL ngehektha, u-30-40 kg wamanzi, bese ufafaza iziqu namaqabunga okhula.

3. Ukuhlakula emasimini amabele: esigabeni samahlamvu angu-5-6, sebenzisa u-750-900 ml ka-72% SL ngehektha, 30-40 kg wamanzi, bese ufafaza iziqu namaqabunga okhula.

4.Ukukhula kwensimu yamabele: esigabeni samaqabunga ama-4-6 ezithombo zokusanhlamvu, sebenzisa u-6000-750 ml ka-72% SL ehektheleni, u-20-30 kg wamanzi, bese ufafaza iziqu namaqabunga okhula.

5.Ukulawula ukhula emasimini e-paddy: ekupheleni kokulinywa kwerayisi, sebenzisa u-525-1000 ml we-72% SL ngehektha, bese ufafaza u-50-70 kg wamanzi.

6.Ukukhipha utshani: sebenzisa u-72% SL1500-2250 ml ihektha ngalinye lotshani, bese ufafaza u-30-40 kg wamanzi.
