试验表明,小麦起身期喷施多效唑,具有降低株高、增加茎粗、提高成穗率、增加穗粒数,减少不孕小穗,增高产量等效果,并且有增强小麦抗病性,抑制穗发芽之功能。喷施浓度以600—800mg/kg 最好。对群体偏大,生长过旺的麦田每亩可用15%可湿性粉剂45—60g,兑水75kg 叶面喷施。能有效的防止倒状,增加产量。但亩用量不宜超过100g,否则会导致贪青晚熟,降低千粒重。 The results showed that spraying paclobutrazol during wheat get up had the effects of reducing the plant height, increasing the stem diameter, increasing the percentage of ear to ear, increasing the number of spikelets per plant, decreasing the number of spikelets and increasing the yield of wheat. Germination of the function. Spraying at a concentration of 600-800mg / kg is best. On the group is too large, over-growing wheat available per acre 15% WP 45-60g, watered 75kg foliar spray. Can effectively prevent inverted shape, increase production. However, the amount of mu should not exceed 100g, otherwise it will lead to greyish late maturity, reduce 1000 grain weight.
