| 摘 要： | 在不同密度下,研究了施用氮肥对玉米新组合同玉1号和同玉386号产量的影响,结果表明,高寒区春玉米在常规的栽培密度和氮肥施用量的范围内,密度和氮肥施用量对玉米产量构成因素的影响是单独起作用的。在具体生产实践中要把握好群体和个体以及密度与土壤肥力、施肥水平、田间管理水平的相互关系,高水肥地块种植密度为55 500～57 000株/hm2、施氮量(折合纯氮)为375 kg/hm2时可以获得最佳产量。

| Abstract: | With new maize combination of Tongyu 1 and Tongyu 386 planted at different densities and under application of nitrogen fertilizer,density and nitrogen effects to yield was studied.The results showed that in high latitude and cold climate areas,maize within the conventional planting density and range of nitrogen fertilizer,density and nitrogen on yield components of maize works alone.In production practice,we should have a good control of the relationship between groups and individuals;density and soil ferti... |
