Njira yoyendetsera mankhwala pogwiritsa ntchito Mepiquat chloride idapangidwa kuti ikhale pachimake chamaluwa cha thonje, cholinga chake ndikuchotsa masamba osabala, kukulitsa kulemera, komanso kulimbikitsa kukhwima koyambirira.
1. Core Mepiquat Chloride Application Protocol
Ikani 12-16 ml ya 25% Mepiquat chloride amadzimadzi njira (kapena 3-4 g wa luso kalasi Mepiquat kolorayidi) pa mu, kuchepetsedwa mu 40-50 makilogalamu madzi. Uza mbewu yonse mofanana, molunjika pa tsinde lalikulu ndi nsonga za nthambi za fruiting. Kwa minda ya thonje yokhala ndi kukula kwakukulu, mlingo ukhoza kuwonjezeka kufika 18 ml/mu; M'minda yomwe ili ndi kukula kochepa, iyenera kuchepetsedwa mpaka 10 ml /ekala.
2. Ntchito Zofunikira za Mepiquat Chloride
Kugwiritsiridwa ntchito kumalepheretsa kukula kwa nthambi za nyengo yochedwa, masamba, ndi mphukira za zomera zosabereka, motero zimachepetsa zinyalala za michere ndikulimbikitsa kusamutsidwa kwa photosynthate kupita ku thonje. Izi zimabweretsa kuwonjezeka kwa kulemera kwa botolo limodzi la 0.2-0.9 g, kufupikitsa nthawi ya kukula kwa boll ndi masiku 1-2, kufulumira komanso kutsekedwa kwa boll, ndi kuwonjezeka kwakukulu kwa chiwerengero cha "thonje isanayambe chisanu" ( thonje lapamwamba lomwe limakololedwa chisanu choyamba chisanayambe).
3. Zowonjezera Zowonjezera
Utsi masana dzuwa; ngati mvula igwa mkati mwa maola 4 ogwiritsidwa ntchito, kupoperanso kumafunika. Mankhwalawa amatha kuphatikizidwa ndi kutsitsi kwa foliar kwa 0.2% -0.3% potaziyamu dihydrogen phosphate kuti apititse patsogolo zotsatira zokulitsa kulemera kwa boll ndikulimbikitsa kukhwima koyambirira.
