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 effect of Papaya-Stylosanthes intercropping on soil nutrients, soil nutrients in different cropping patterns were sampled and analyzed. The results showed that intercropping and covering with column flower could increase the content of soil organic matter and alkalized nitrogen, and the coverage could increase the content of available and available potassium in soil. The contents of available phosphorus and available potassium in the intercropped papaya - , Soil microorganisms and organisms increased.
