Abstract: 【Objective】 To study the degree of spatial variation and distribution of soil nutrients in Shihezi field of the eighth division of Xinjiang Production and Construction Corps with a view of providing the basis for scientific and rational fertilization. 【Methods】 Soil moisture monitoring system, GIS and geostatistics were used to study the variation of soil moisture content and temperature, spatial distribution and variation of soil nutrients in cotton fields. 【Results】 (1) According to the monitoring data analysis, with the increase of irrigation amount and cotton growth period, the change trend of soil water content in the upper layer of 0-30 cm was obvious than that in the lower layer of 40-60 cm soil, the compensation water in 20 cm soil layer was relatively sufficient, and the soil water content at each monitoring point was basically maintained in a more suitable range. The temperature of each layer of soil was affected by the atmospheric temperature and weakened with the depth of soil layer, and the lag time was prolonged with the depth of soil layer. (2) Soil total nitrogen, available phosphorus and available potassium all showed moderate variation; (3) Soil available potassium between 25%-75% (0.497) showed moderate spatial autocorrelation, soil total nitrogen, available phosphorus index of less than 25% showed strong spatial autocorrelation. 【Conclusion】 Using the real-time monitoring system of soil moisture to guide the irrigation of cotton field, the irrigation of cotton decreased by 1-3 times during the whole growing period and saved about 20% of water resources. The variation of soil total nitrogen, available phosphorus and available potassium in the study area showed moderate variation characteristics, total nitrogen and available phosphorus showed strong spatial autocorrelation, and available potassium showed moderate spatial autocorrelation.
