土壤有机质与氮素供应的相关关系

Relations Between the Manure and Nitrogen Supply in the Soil

土壤的氮素供应状况,对林木生长至关重要,该文就土壤有机质与氮素供应的相关关系进行了研究,结果表明,土壤全氮和速效氮的含量均与土壤有机质含量呈紧密的正相关关系。土壤中有机质含量的高低直接影响土壤氮素供应水平。

The supply of nitrogen in the soil is an important factor for tree growth.Relations between the manure and nitrogen supply were studied in the paper.The results were that there was a closely positive relation between contents of whole nitrogen and quick-acting nitrogen and manure in the soil.The content of manure directly affected the level of manure supply.
