| 摘 要： | 2005～2007年以中层黑土土壤为研究对象,研究免耕和秋翻处理对黑土农田土壤温湿效应的影响.结果表明:不同耕作处理对春季播种期土壤含水量影响较大,玉米田和大豆田免耕处理分别显著高于秋翻6.2％和6.6％.在玉米抽雄期,玉米田和大豆田2种耕作处理条件下土壤含水量均没有显著差异,但与秋翻相比,免耕保持了较好的耕层土壤水分...

| Abstract: | The impact of no tillage(NT)and mouldboard plow(MP)on black soil temperature and humidity in northeast China were studied from 2005 to 2007.The result showed that tillage methods greatly affected soil moisture content in spring sowing stage.In the corn and soybean farmland,the soil moisture of NT was significantly higher than MP for 6.2% and 6.6%,respectively.In corn tasseling stage,there was no significant difference between two tillage methods in different crop farmland.Compared with MP,NT maintained a be... |
