摘　　要：玉米“四两”高产栽培技术，旨在鄂西北北亚热带与暖温带之间进行熟制改革，改旱地两熟制为三熟制。创建两苗（春、夏玉米营养钵育苗）、两膜（春玉米钵苗塑膜覆盖、中高山玉米地膜栽培）、两定（定产定肥）、两保（保土保水）（即“四两”）的农业系统工程措施，实现年产粮食１８１３４ｋｇ／ｈｍ２，利润５４９５元／ｈｍ２。与两熟制比，粮食增产１０４０９ｋｇ／ｈｍ２，净增１５４％。The fourtwos highyield corn cultivation technology is intended to reform the ripe cycle in the northwestern part of Hubei province, which is a transitional area between the north subtropical zone and the warm zone. More specifically, the technology is intended to change the tworipe cycle into a three ripe cycle in dry land in order to obtain an average yield of 18134 kg/hm 2, a profit of 5495 yuan/hm 2 . Compared with the tworipe cycle, the yield increases 11604 kg/hm 2 with a 178% increase. 
