生物炭对沙化土壤理化性质及绿豆幼苗生长的影响

摘要

通过对吉林省西部大安市沙化土壤理化性质和绿豆生长影响的研究,分析了生物炭施加对沙化土壤理化性质及植物的影响,从而探讨施加生物炭后沙土的改良作用.研究结果表明:施加生物炭对土壤速效N、速效P、速效K和有机质的含量以及pH值都有明显的影响.同时,生物炭不但能提高绿豆幼苗的含水量,而且能促进绿豆幼苗的生长.研究结果将为了解生物炭对植物生长的影响作用、沙化土壤的可持续利用,以及生物炭在土壤改良等方面提供一定的科学依据.%Through desertification of soil research on physical and chemical properties and mung beans grow Da′an in the west of Jilin province, the influence of the biochar on desertification soil physical and chemical properties and plant was analyzed, and the amelioration of biochar on desertification soil was also discussed.The results showed that biochar had obvious influence on desertification of soil organic matter content, pH value and available nitrogen, phosphorus and potassium content.At the same time, it could improve the water content of mung bean seedlings and promote the growth of its seedlings.
