作者所提出的夏玉米栽培上的几个问题,可供读者参考。但文中未提出玉米螟的防治问题,是一缺憾。又文中介绍的用绳拉法进行人工辅助授粉,还有待进一步研究,因为绳拉法容易折断雄穗,同时不能做到有意识的辅助授粉和选择授粉。目前仍以利用授粉器,及时采粉授粉,比较有把握。 The author put forward several issues on the summer corn cultivation, for readers reference. However, the article did not put forward the prevention and control of corn borer is a regret. Artificial pollination by rope pull method, which is described in the text, is yet to be further studied because the rope pull method easily breaks the tassel and at the same time can not achieve conscious secondary pollination and selection of pollination. At present, the use of pollinators is still available, and timely pollination of pollination is more certain.
