摘要
通过测定土壤水溶性磷、速效性磷，研究了木质素对土壤残余磷的释放作用。结果表明：木质素对土壤残余磷具有明显的释放作用。木质素用量越大，土壤粘粒越多，残余磷含量越高，木质素释放残余磷的数量越多。
The effects of lignin on the liberation of residual phosphate in soil were studied by determining water-soluble phosphate and rapidly available phosphorus. The results showed that lignin could help liberate the residual phosphate in soil. The released quantity of residual phosphate was opositively related to the content of clay and residual phosphate in soil, and the concentration of lignin in the extracting solution.
