微生物土壤改良剂对东北地区风沙土改良效果研究

Study of the Effect of Microbial Soil Ameliorant on Aeolian Sandy Soil Improvement in Northeast China

在阜新风沙地区进行长期土壤定位改良试验,设计三个处理:传统种植(CK),有机肥处理(T1),微生物土壤改良剂处理(T2)。通过对比试验研究了微生物土壤改良剂对东北风沙土的改良效果。试验结果表明,和传统有机肥改良相比,微生物土壤改良剂对风沙土的改良效果更好,改良后的土壤保水保肥能力更强。

Long-term soil orientation improvement experiment in Fuxin Aeolian Sandy Soil area,and three treatments were designed：traditional planting （CK）,organic fertilizer treatment （T1）,and microbial soil im- prover treatment （T2）.The effect of microbial soil amendment on the northeastern aeolian sandy soil was stud- ied by contrast experiment.The results showed that compared with the improvement of traditional organic ma- nure ,the effect of microbial soil improver on aeolian sand was better,and the soil improved ,which water and fertility retention was better.
