摘要
[目的]研究不同行距配置对玉米干物质积累和产量的影响.[方法]选用耐密、高产、适宜机械化收获的玉米新品种大丰30作为试验材料,在67 500株/hm2的种植密度下,设置60.0、70.0、76.0、86.0 cm 4个行距处理,研究其对玉米干物质积累和产量的影响.[结果]在行距为70.0 cm处理时,玉米单株干物质积累量最大,产量最高.[结论]采用70.0 cm行距种植大丰30号,经济产量最高.该行距配置合理,便于在农业生产中进行玉米机械化和简约化操作.
Abstract
[Objective] To research the effects of row spacing on dry matter accumulation and yield of spring maize.[Method] New variety Dafeng 30 was used as test material,which had the characteristics of high yield,dense resistance,and suitable for mechanized harvesting.Under the planting density of 67 500 plants/hm2,four levels of row spacing were designed,which were 60.0,70.0,76.0 and 86.0 cm.Their effects on the yield and dry matter accumulation of maize were researched.[Result] When the row spacing was 70.0 cm,dry matter accumulation of maize per plant was the maximum,and the yield reached the highest.[Conclusion] 70.0 cm row spacing is adopted for Dafeng 30,which is reasonable and the economic yield is the highest.This method is suitable for the mechanized and simplified operation of maize in agricultural production.
