对湖北省蚕桑主产区罗田、麻城、英山、远安、南漳、蕲春及武汉等县市的 90个有代表性的桑园土壤养分进行了测试分析 ,在此基础上对桑园土壤养分含量进行丰缺分级。结果表明 ,全省桑园土壤肥力水平不高 ,有机质质量分数普遍偏低 ,平均只有 0 95 % ,速效N、P、K平均含量分别为 80 4、9 71和87 3mg·kg-1,有效Ca和Mg平均含量分别为 85 5 0和 15 8 0mg·kg-1,有效Cu和有效Zn平均含量分别为 0 80和 0 97mg·kg-1;鄂东部分桑园土壤阳离子代换量平均只有 8 81cmol·kg-1,土壤有效S、有效B、有效Mo和有效Cl含量大多处于缺乏状态 ;主产区桑园土壤有机质含量普遍偏低 ,土壤缺乏速效养分氮、磷、钾、钙、镁程度严重 ,微量元素养分铁、锰、铜均存在缺乏和过量情况 ,有一半桑园土壤缺锌。结果还表明 ,不同种植区域桑园的土壤养分失调的种类及程度有较大的变化 90 representative mulberry fields in Luotian, Macheng, Yingshan, Yuan’an, Nanzhang, Hunchun and Wuhan counties in Hubei province were tested and analyzed. Based on this, Soil nutrient content of the garden abundance and lack of grading. The results showed that the soil fertility of mulberry fields in the province was not high, and the mass fraction of organic matter was generally low, with an average of only 0 95%. The average contents of available N, P and K were 80 4, 9 71 and 87 3 mg · kg -1, respectively The average contents of Ca and Mg were 85 5 0 and 15 80 mg · kg -1, respectively. The average contents of available Cu and available Zn were 0 80 and 0 97 mg · kg -1, respectively. On the average, 8 81cmol · kg-1, soil available S, available B, available Mo and available Cl were mostly in the deficient state. The content of organic matter in the mulberry field in the main producing areas was generally low, and the soil lack of available nutrients such as nitrogen, phosphorus, potassium, calcium and magnesium The degree of seriousness, the trace elements of nutrient iron, manganese, copper, there is a lack of and over the situation, there are half of zinc deficiency of mulberry fields. The results also showed that different types of mulberry fields in the cultivation of soil nutrient imbalance in the type and extent of major changes
