摘要
以京农科728和金农738为试验材料,研究3个不同种植密度下化控剂玉黄金(主要成分胺鲜酯和乙烯利)对春玉米抗倒伏性状及产量的影响。结果表明,施用玉黄金后,能够降低株高和穗位高,缩短节间,提高穿刺强度和压碎强度,从而提高抗倒伏性能。与清水对照相比,玉黄金处理后,随密度升高,京农科728产量分别提高12.54%、11.24%和8.81%,金农738产量分别提高4.39%、4.05%和7.00%。为春玉米高产及实现全程机械化提供参考。
The effect of the chemical regulator of Yuhuangjin on the lodging resistance traits and yield of spring maize(Jingnongke 728 and Jinnong 738)under three planting densities were examined.The results indicated that Yuhuangjin could shorten plant height,ear height and internodal length,improve puncture strength and compressive strength to improve stability than controls treated with clear water.Compared with the clear water treatment,with the increasing of planting density,the yields of Jingnongke 728 were increased by 12.54%,11.24%,and 8.81%,respectively,the yields of Jinnong 738 were increased by 4.39%,4.05%and 7.00%,respectively.This provided the references for realizing high yields and mechanization of spring maize.
