In this paper,solid natural minerals-mineral humus(generally present on the surface of coal mines)and natural plant waste-deciduous leaves are used as raw materials,by mixing the selected inorganic and organic matter in a certain proportion,with the help of external impact force to achieve microscopic blending of two substances with different properties,to improve the surface imperfection and fusion degree of the two substances,a mixture with more microsurface activation energy than a single component can be obtained.Through soil cultivation and pot planting experiments,to study the effect of inorganic-organic mixtures in different proportions in soil improvement.Through the determination of soil microbial community structure,soil physicochemical properties,soil enzyme activity,and the impact on the growth of tomato plants,to optimize the optimal ratio of the inorganic-organic mixture and its application amount.And on this basis,the mixture was used for the cultivation of edible mushrooms pleurotus eryngii and camellia sinensis.The research results are as follows:1.Using mixed powder to cultivate soil can increase the content of soil organic matter and humic acid,as well as increase the number of microorganisms and the abundance of microbial communities.Compared with the blank control T,the organic matter content of T2(the mass ratio of ginkgo biloba powder and lignite powder was 10:1),T3(100:1)and T4(1000:1)were significantly increased by 57.22%,45.44% and 22.86%,respectively(P <0.05),the content of humic acid increased by 179.55%,142.16% and 118.77% respectively(P<0.05);In terms of soil microorganisms,A2(the mass ratio of ginkgo biloba powder and lignite powder is 10:1),A3(100:1),and A4(1000:1)increased the number of bacterial species compared with the blank control A1,among them,A2,A3 and A4 increased the relative abundance of Proteobacteria andα-Proteobacteria;A2 increased the number of fungi species in soil compared with A1.This indicates that the application of the mixture is beneficial to increase the content of organic matter and humic acid in the soil,and can also increase the species abundance of microorganisms.2.In the pot experiment,T1(the mass ratio of ginkgo biloba powder and lignite powder is 10:1),T2(100:1),and T3(1000:1)compared with the blank control T,the soil total nitrogen content was significantly increased by 28.22%,30.69% and 33.17% respectively(P<0.05),the available phosphorus content increased significantly by 11.72%,5.14%,and 4.75%,respectively(P<0.05);Compared with T invertase activity,T1,T2 and T3 increased by 134.67%,109.71% and 29.82% respectively(P<0.05);Urease activity increased by 186.55%,111.07% and 50.85%respectively(P<0.05);The catalase activity increased by 194.50%,112.31% and 90.88% respectively(P<0.05).T1,T2,T3 were 13.35%,5.11%,and 8.27% higher than T tomato plants,respectively.Select T1 to be applied to the soil for the second planting,and apply 60 g of T1 mixed powder to the soil of 2600 g dry weight,which is the most suitable for plant growth.3.With the mass ratio of ginkgo biloba powder and lignite powder as10:1,in the cultivation of king oyster mushroom,the raw material sawdust is completely replaced,which can increase the average yield per package,,compared with CK,YX1 increased by 17.67%;In tea tree mushroom cultivation,complete replacement of sawdust with mixed flour can increase the average yield per bag,compared with YCK,YC1 increased by 7.85%.
