玉米产量与收获期有很大关系,如能在最佳期收获,可增产5—10％,反之,收获过早、过晚都会影响产量。近些年,不少单位作过玉米收获期试验,结论是“玉米适当晚收能增产”。所谓晚收是针对目前有些地方在玉米刚刚进入成熟期的9月下旬就开始收获而言。试验证明,玉米在完熟期虽着霜冻,但籽仍可以不断增重, Corn yield and harvest have a lot to do, such as in the best harvest, can increase 5-10%, on the contrary, the harvest is too early, too late will affect the yield. In recent years, many units made corn harvest test, the conclusion is that “Corn late harvest to increase production.” The so-called late harvest is aimed at some areas in the corn just entering the maturity of the beginning of late September began to harvest.
