小麦垄套夏玉米生长期较短,再加上麦田套种,不能进行整地、施基肥、生长条件较差;与小麦共生期夏玉米幼苗生长又受到一定的影响.麦收后必须加大措施,以促为主,精心管理,才能获得较高的产量.我市推广小麦垄套夏玉米已有近30年的历史,目前全市小麦垄套夏玉米达31万亩,占玉米总面积的90%以上,1996年全市玉米总面积35万亩,平均亩产556kg,最高亩产达700kg以上,多年的大面积实践经验,要夺取小麦垄套夏玉米高产,在田间管理上必须抓好“四促一保”管理技术.
Wheat ridge sets of summer maize growth period is short, together with the wheat field interplanting, can not be site preparation, base fertilizer, poor growth conditions; and corn symbiotic summer corn seedling growth is affected to some extent. Promote the main, well-managed in order to obtain higher yields .Town to promote wheat maize summer maize nearly 30 years of history, the city’s summer maize up to 310000 acres of corn, accounting for more than 90% of the total area of corn In 1996, the total area of maize in the whole city was 350,000 mu with an average yield of 556kg per mu and the highest mu yield reached more than 700kg. After years of extensive practical experience, it was necessary to seize the high output of summer maize with wheat ridge cover, Paul "management technology.
