When planting grapes, we must pay attention to changes in soil moisture, soil moisture meter can help us easily and quickly manage the changes in vineyard soil moisture. The soil moisture at all depths of the vineyard is subject to normal distribution. The average soil moisture at each level increases with depth; the soil moisture at different levels has a medium variation intensity, and the soil moisture coefficient of variation appears with depth. The trend of increased first and then decreased. The soil moisture in the root zone is affected by the growth and evaporation of the grape, so the variation intensity is greater. The geostatistical analysis shows that the theoretical models of the optimal variability of soil moisture in each layer of the study area are the exponential model and the spherical model. The soil moisture at each level has a strong spatial correlation, and presents a simple patch distribution, illustrating the soil The spatial variability caused by intrinsic factors such as spatial structure and climate plays a major role. The effective ranges of soil moisture variability at each level are 117.04, 167.92, and 174.81 m, respectively. Spatial autocorrelation of soil moisture exists within the effective range of variation. After this range, the spatial autocorrelation disappears. The value of soil moisture in the experimental area showed a tendency of high in the southwest and northeast, lower in the middle and southeast. According to the spatial distribution of soil moisture in the root zone, the soil moisture in the study area was partitioned, and then irrigation was developed according to the soil moisture in each area. Can achieve a reasonable distribution of water and precision irrigation. Classical statistics can determine the number of soil moisture samples, but in the design, we must also consider the spatial structure of soil moisture, combined with geostatistical methods to reasonably design the spatial location of the sampling point, and draw up a reasonable sampling program.
