| 摘 要： | 研究了玉黄金、烯世宝、玉米壮丰灵、玉米健壮素4种玉米生长调节剂在金海5号玉米上的使用效果,结果表明几种植物生长调节剂对玉米的株高和穗位高都有不同程度的降低作用,同时降低玉米空秆率和倒伏株率.玉米主要经济产量性状穗长、穗粗、秃尖长及百粒质量都有一定的改善,产量水平均有较大幅度的提高,其中玉黄金300 ml/hm2处理比对照增产达17.43％.

| Abstract: | The reseamh reviewed use effects of Yuhuangjin,Xishibao,Zhuangfengling and Jianzhuangsu on Jinhai No.5.The results showed plant height and ear height declined in varying degrees,as well as empty-stalk rate and lodging rate,with the plant growth regulators applied.Economic characters all improved,including ear length and diameter,barren-tip length and hundred-seed weight,and com yield went up significantly on average.For example,the increased yield can be as high as 17.43％ when Yuhuangjin was applied at 30 ml/hm2. |
