| 摘 要： | 田间试验地表覆膜和覆草对夏玉米生长、物质分配和养分吸收利用的影响.结果表明:在夏玉米全生育期降雨量大(但玉米生育初期降雨量相对小)的年份,采用秸秆覆盖、地膜覆盖措施能提高夏玉米各时期干物质累积量,具有显著的增产效果,氮肥利用率明显提高.氮携出量比常规对照增加,但叶片氮素残留量较大,覆盖措施对夏玉米干物质的分配和收获指数无显著影响.

| Abstract: | Field experiment was used to investigate the effects of plastic film mulching and straw mulching on the growth,dry matter distribution and nutrient uptakes of maize.In the test year,there was plenty of rainfall during the maize growth period but only a little at the early stage.Biomass and yield of maize were improved due to straw mulching or plastic film mulching.Maize NUE was improved as well.The nitrogen uptake of maize with mulching treatments was higher than that without mulching(CK),while nitrogen rem... |
