改革耕作制度推广间作套种三种三收后,玉米由过去的平作改为套作,种在埂上,播种时间也和春玉米、夏玉米不同。条件变了,怎么管才能高产,特别是水分管理是以抗旱为主还是防涝为主,什么时期以抗旱为主,什么时期以防涝为主,达是当前生产中迫切需要解决的问题。达方面近年来郊区广大群众已积累了一些经验,我们试图从农业气候角度对中茬玉米的灌溉问题作一初步分析,供参考。 Reform farming system to promote intercropping intercropping three kinds of three after the harvest, the conversion of corn from the past to the intercropping planted in the mound, sowing time and spring corn, summer corn is different. Conditions have changed, how to control the high yield, especially water management is mainly drought-based or waterlogging-based, when to drought-based, what time to prevent flood-based, up to the current production is an urgent need to be addressed. In recent years, the suburban masses have accumulated some experience. We try to make a preliminary analysis on the irrigation of stubble corn from the agricultural climate perspective for reference.
