摘要
为了揭示番木瓜-柱花草间种模式对土壤养分的影响,对不同种植模式的土壤养分进行采样和养分分析。结果表明:间种和覆盖柱花草可以提高土壤中有机质和碱解氮的含量,覆盖可以增加土壤中速效磷和速效钾的含量,番木瓜-柱花草间种模式土壤速效磷与速效钾含量减少,土壤微生物及生物数量增加。
In order to reveal the mode of papaya-stylosanthes on soil nutrients, sampling and nutrient analysis of soil nutrients in different planting patterns were carried out. The results showed that intercropping and cover stylosanthes could increase the content of soil organic matter and available nitrogen, cover could increase the content of soil available P and K. In papaya-stylosanthes mode, available P and K content decreased, the number of soil microorganism and organisms increased.
