Abstract

The invention relates to a measurement and calculation method for a soil infiltration parameter of a field scale. The method comprises the steps of performing a K-S normality test on soil infiltrationparameter actual measurement data of each test point; obtaining soil infiltration parameter theoretical data obeying normal distribution; calculating a test variation function of the soil infiltration parameter theoretical data, and performing fitting on the test variation function by using a theoretical variation function model to obtain a theoretical semivariance function of the soil infiltration parameter; according to the theoretical semivariance function and a statistical eigenvalue, calculating a non-conditional simulation value Z*s of the soil infiltration parameter and a non-conditional simulation value Zs of the soil infiltration parameter of an untested position of a to-be-tested region; performing Kriging interpolation on the soil infiltration parameter actual measurement dataand the non-conditional simulation value Z*s of the soil infiltration parameter to obtain data Z*ok and Z*sok; and according to the non-conditional simulation value Zs and the data Z*ok and Z*sok, calculating a soil infiltration parameter value of the untested position of the to-be-tested region. According to the method, the technical support can be provided for optimizing ground irrigation systemdesign and improving field irrigation management level.

Description

technical field [0001] The invention relates to the technical field of irrigation, in particular to a method for measuring and calculating soil infiltration parameters at the field scale. Background technique [0002] The spatial variation of soil infiltration exists objectively in the irrigation system and has a great influence on the irrigation process and irrigation performance. And when the accuracy of field surface leveling is higher, the impact of infiltration space variation on border irrigation performance is more significant. In order to meet the needs of agricultural scale and modernization, the precision of land leveling is getting higher and higher. Therefore, the influence of spatial variation of soil infiltration on irrigation performance should be considered in the design of surface irrigation system and field irrigation management. However, in related studies, it is necessary to describe the spatial variability of soil infiltration with the help of soil infi...
