Abstract:
Taking corncob and rice husk as test materials,setting rice husk (G),corncob (Y) and the mixed organic materials of rice husk (G)+corncob (Y) as treatments.The effects of different organic material treatments on soil nutrients, particle size distribution and enzyme activities in mushroom-vegetable rotation were studied,in order to provide a reference for the efficient utilization of agricultural resources and the improvement of soil quality.The results showed that the content of TN,TP,AN,AK and organic matter were 16.87%-45.23%,30.95%-44.76%,29.41%-33.33%,35.14%-63.64% and 22.61%-53.87% higher than those of the control,respectively.According to the classification of soil particle size,the range of particle size detected in this study was 0-200 μm.The content of clay increased significantly after G+Y treatment.The content of clay,coarse clay and fine silt in Y treatment decreased significantly,and accounted for a large proportion,while the content of coarse silt,fine sand and coarse sand increased significantly.All treatments could significantly increase soil urease activity.G and G+Y treatments decreased sucrase activity,and G+Y treatment decreased acid phosphatase activity,but catalase had little effect.There was a significant or extremely significant positive correlation between TN,TP,AN,AK,organic matter and urease.There was a significant positive correlation between TN and TP,AK,respectively.There was a significant correlation between TN and AN.TP was significantly positive correlation with AN,significantly positive correlation with organic matter.AN was significantly correlation with AK,organic matter and urease.AK was significantly correlated with organic mechanism and urease.There was significant correlation between organic matter and urease.Different organic materials could significantly improve soil nutrients and enhance soil enzyme activities.Generally speaking,single organic material was better than mixed materials in improving soil nutrients and enzyme activities,but mixed materials have greater impact on soil aggregate structure than single materials.
