Abstract:: Taking watermelon→watermelon，watermelon→mung bean，watermelon→pumpkin，watermelon→oil sunflower for example，the soil physical and chemical properties of gravel mulched field in Xiangshan area，Zhongwei City，Ningxia Hui Autonomous Region were studied.Its relationship with soil microbial traits was explored using canonical correlation analysis.The results showed that：Watermelon→pumpkin soil nutrient content was higher than the other five rotation modes，watermelon→pumpkin will slow down the gravel mulched field soil nutrient depletion in these six modes，thereby slowing the aging of the gravel mulched field，to extend the use of gravel mulched field life.Combination of the six rotation modes of soil physical and chemical properties and traits of microbial 14 indicators，canonical correlation analysis showed that soil physical and chemical properties that affect the microbial groups mainly actinomycetes in the soil microbial groups，the number of nitrifying bacteria and cellulose decomposing bacteria soil physical and chemical properties that affect the density of microbial population in soil physical and chemical properties of nitrogen，available phosphorus and total salt content.
