为期４年的研究结果表明，采用套种晚熟玉米－晚播独秆小麦的一年二作技术体系是实现亩产吨半粮的较好途径。这一体系的推行，将给传统种植方式带来一些重要的变革。即改小麦适期早播为适当晚播；改玉米不等行套种为等行套种；改早套玉米为晚套玉米，并改变了玉米砍青腾茬早种麦的错误认识和做 The results of the four-year study show that using the two-year technical system of intercropping late-maturing corn-late sowing single-stalk wheat is a good way to realize the half-grain yield per mu. The implementation of this system will bring some important changes to the traditional planting methods. That is, to change the wheat early sowing suitable late sowing; change maize unequal intercropping for intercropping; early maize sets of late corn, and change the maize stubble stubble early wheat misunderstanding and do
