菌糠改良土壤孔隙度效果的研究

摘要

以香菇菌糠为底肥,以种植玉米的土壤为研究对象,研究了菌糠不同施用量（0、2 500、5 000、7 500和10 000 kg/hm2）对土壤孔隙度的改良效果。结果表明：施用菌糠改良土壤孔隙度效果良好,随着菌糠施用量由0增加到10 000 kg/hm2,土壤孔隙度由40.0%增加到54.8%,处理间差异达到了极显著水平。在该土壤上种植的玉米产量和品质均有所提高,施用香菇菌糠改良粘黄土土壤孔隙度是可行的。%Taking maize soil as researching material,the effect of different mushroom waste amounts（0,2 500,5 000,7 500 and 10 000 kg/hm2）on improving soil porosity was examined.The results showed that the effect of mushroom waste on improving soil porosity was good;soil porosity increased from 40.0% to 54.8%,when applied amount of mushroom waste increased from 0 to 10 000 kg/hm2;the differences among treatments were significant.Mushroom waste could ameliorate the porosity of sticky loess,and then enhance the yield and improve the quality of maize.
