| 摘 要： | 以夏玉米品种郑单958、浚单20和先玉335为试验材料,从不同收获时期的籽粒含水量、千粒重及产量方面,分析了夏玉米适时晚收的增产效应。结果表明：玉米适时晚收具有明显的增产效果。目前黄淮海地区生产上主推的玉米品种达到完全成熟,收获期在10月10号左右为宜,籽粒含水量下降到28%以下可作为收获期的标准。

| Abstract: | The harvesting time on the grain moisture,1 000-grain weight and yield of summer maize varieties Zhengdan 958,Xundan 20 and Xianyu 335 were studied.The results showed that timely harvest had obvious effect on increasing yield.The most suitable harvest time of summer maize in Huanghuaihai Region was October 10 or so.When the grain moisture dropped to below 28%,the maize could be harvested. |
