| 摘 要： | 通过黑钙土的培养试验，研究了作物根茬施入土壤后不同分解时期对土壤有效微量元素的影响。在整个培养过程中，根茬处理的土壤有效微量元素的含量均高于对照。施用玉米根茬土壤有效锌，锰，铁，铜提高幅度分别为０．２１－０．６４ｍｇ／ｋｇ，２．３０－３．。７２ｍｇ／ｋｇ，３．９６－６．６３ｍｇ／ｋｇ，０．２１－０．６８ｍｇ／ｋｇ；施用大豆根茬土壤有效锌，锰，铁，铜提高幅度分别为０．２８－０．５０ｍｇ／ｋｇ，０．３

| Abstract: | The Effectof crop stabbles put in soil in different decomposition phase on effective trace elements of soil by cultural experiment of churnozem were stuied. During cultural course, the soil effective trace elemenmts content of treatment with crop stubble was higher than control grops, and increased extent of the effective Zn, Mn, Fe, Cu was 0.210.64mg/kg, 2.303.72mg/kg, 3.966.63mg/kg, 0.210.68mg/kg in maize stubbles, respectively. The maize stubbles was better than soybean stubbles. |
