中药药渣堆肥应用于苏打盐碱土改良的可行性研究
Feasibility of Using Traditional Chinese Medicine Residue Compost for Soda Saline-alkali Soil Improvement
摘要
Abstract
Using soda saline-alkali soil in Songyuan City,Jilin province,as the test soil,two com-monly used traditional Chinese medicine residue compost products for heat clearing and detoxifying were applied to soda saline-alkali soil to explore the feasibility of applying the residue compost to im-prove soda saline-alkali soil.The results showed that under laboratory conditions,when the applica-tion rate of compost reached 3%,soil pH decreased to 8.55,conductivity decreased to 538 μS/cm,ESP decreased to 32.59%,total salt content decreased by 12.50%,and contents of available N,P,and K increased by 91.90%,44.29%,and 55.22%,respectively.Content of organic matter increased significantly,and it could effectively improve permeability of soda saline-alkali soil,promote aggre-gation and transformation between different particle sizes of aggregates,increase content of aggre-gates with particle sizes>0.25 mm,and improve water stability of soil aggregates.The application of heat clearing and detoxifying traditional Chinese medicine residue compost products can improve the physicochemical properties of soda saline-alkali soil.关键词
