为了明确微生物α多样指数与土壤理化性质的关系，对α多样指数和土壤理化性

In order to clarify the relationship between microbial alpha diversity index and soil physical and chemical properties, correlation analysis was conducted on alpha diversity index and soil physical and chemical properties indexes (pH, organic matter, total nitrogen, total carbon, total phosphorus, total potassium) (Table 4). Bacterial Chao1 index was significantly negatively correlated with total potassium content in soil; bacterial ACE index, Shannon index, Simpson index was significantly negatively correlated with total potassium content in soil; Coverage index was significantly positively correlated with pH value, and was related to total phosphorus and organic matter in soil The content was significantly negatively correlated with the total nitrogen content. The fungal Chao1 index was significantly negatively correlated with total potassium content in the soil; the Simpson index was significantly negatively correlated with pH and positively correlated with total nitrogen. Overall, the effects of total potassium, pH, and total nitrogen content in soil on soil community richness are more significant

In order to clarify the relationship between microbial alpha diversity index and soil physical and chemical properties, the correlation analysis of alpha diversity index and soil physical and chemical properties index (pH, organic matter, whole nitrogen, total carbon, whole phosphorus, full potassium) was carried out (Table 4). The bacterial Chao1 index was significantly negatively correlated with the total potassium content in the soil, the bacterial ACE index, the Shannon index, the Simpson index were significantly negatively correlated with the whole potassium content in the soil, and the Coverage index was significantly positively correlated with the pH, and the total phosphorus and organic matter content in the soil was significantly negatively negative. The fungal Chao1 index was significantly negatively correlated with total potassium content in the soil, and the Simpson index was significantly negatively correlated with pH and significantly positively correlated with whole nitrogen. In general, the content of whole potassium, pH and total nitrogen in soil had a significant effect on the richness of soil communities.

In order to clarify the relationship between the α diversity index of microorganisms and the physical and chemical properties of soil, correlation analysis was conducted on the α diversity index and the physical and chemical properties of soil (pH, organic matter, total nitrogen, total carbon, total phosphorus, and total potassium) (Table 4). There was a significant negative correlation between bacterial Chao1 index and total potassium content in the soil; there was a significant negative correlation between bacterial ace index, Shannon index and Simpson index and total potassium content in the soil; there was a significant positive correlation between coverage index and pH value, a significant negative correlation between coverage index and total phosphorus and organic matter content in the soil, and a significant negative correlation between coverage index and total nitrogen content. There was a significant negative correlation between the Chao1 index of fungi and the total potassium content in soil, and a significant negative correlation between the Simpson index and the pH value, and a significant positive correlation between the Simpson index and the total nitrogen. In general, total potassium, pH value and total nitrogen content in soil have significant effects on the richness of soil community<br>
