山西东南部复播玉米高产模式研究
High Yield Model of Multiple Cropping Corn in the Southeast of Shanxi
摘要
Abstract
[Objective] High yield model of multiple cropping corn in the Southeast of Shanxi was studied .[ Method] The experiments of maize variety, density and sowing time were carried out, the design of random area was used to compare the yield and its component and the main agronomic traits.[Result]Quanyu 2, Demeiya 1, Kxw116, Kezaoyu 3 had great potential to increase their production capacity and good fertili-ty, which were more suitable for the cultivation of wheat interplanting corn.The optimum planting density was 82.5 thousand plants/hm2 , the yield was 7670.5 kg/hm2 .With the delay of planting time, the grain weight and yield of corn showed a decreasing trend,the best sowing time was from May 25 to June 5.[Conclusion]This study provided scientific theoretical basis for corn production and promoted the sustainable de-velopment of corn production.关键词
