| 摘 要： | 采用盆栽试验,通过对紫云英翻压后不同时期的水稻播秧和不播秧土壤样品进行测定,研究了紫云英翻压后土壤养分的变化规律.结果表明:紫云英翻压第1年能提高土壤中速效氮、速效磷、速效钾含量、增加土壤有机质含量,但增加幅度不大.水稻生长前期紫云英腐熟,养分没有释放出来,所以翻压紫云英田块前期应该施足氮肥,水稻进入旺盛生长期仅仅依靠...

| Abstract: | Soil nutrents change was tested by ploughing down Astragalus sinicus in pot experiment.The result showed that ploughing down Astragalus sinicus could increase content of soil organic matter,available N,P and K in the first year,but the range of increase was not obvious.and the content of N nutrient was not enough for rice grow in the early stage while available P and K was not sufficient for rice grow in the late stage depend on ploughing down Astragalus sinicus only.So it should be apply N,available P and ... |
