蔗糖基聚合物对夏玉米增产效果的试验研究

Study on Effect of Sucrose-based Polymers on the Yield of Summer Maize

在夏玉米不同生长期用2%浓度的蔗糖基聚合物作叶面喷施处理。结果表明,蔗糖基聚合物能够提高子粒千粒重,增加玉米产量,尤以拔节期+抽穗期+灌浆期共喷施3次的处理效果最好,比对照增产27.8%。

The effects of 2% solution of sucrose-based polymers in different treatments on the growth of summer maize were ：reported. The results showed that the 1 000-grain weight and the yield of summer maize could be raised by using sucrose-based polymers. The treatment of spraying three times separately on elongation, heading and grain-filing stages was found to be the best. The yield was 27.8% higher than that of comparison.
