套种宽窄行对夏玉米生长发育及产量的影响
Effect of Different Wide-narrow Row Spacing Mode on Growth and Yield of Summer Maize
摘要
Abstract
With the equal row spacing of flat planting corn as CK, the growth and yield of summer maize were studied on thewide-narrow row spacing mode in west Henan Province. The results showed that compared with the equal row spacing, the grainfilling rate of the wide-narrow row spacing mode increased significantly in favor of summer corn growth, dry matter accumulationand stem length. Besides, the former of leaf area index increased rapidly early, the kernel weight, grain traits significantly hasimproved, compared with equal's, the average yield of wide-narrow row spacing mode was 6660.2kg-hm-2, the rate increased by16.7%.关键词
