In view of the shortage of irrigation water resources and soil salinization in Ningxia Yinhuang irrigation area, the present study was conducted from August 2018 to March 2019, to study the effects of film mulching and straw burying on soil moisture, nutrient, soil salt and tomato yield. Four treatments were settled: T1(film mulching and straw burying), T2(no film mulching but straw burying), T3(film mulching but no straw burying), T4(no film mulching and no straw burying). Results indicated that, the soil moisture of 0—20 cm layer during tomato growth period followed T1>T2>T3>T4, both the film mulching and straw burying contributed to the improvement of soil water storage capacity in 0—40 cm layer and the restraining of salt accumulation in topsoil. Especially, combination measures of film mulching and straw burying had significant influence on moisture conservation and salinity control in 0—40 cm layer, taking T4 treatment as comparison, the capacity of salinity controlling for T1 treatment increased by 27.94%; straw burying can improve the soil nutrient in 0—40 cm layer effectively; comparing the measure of no film mulching and no straw burying, the irrigation water use efficiency and tomato yield were improved for the combination measure of film mulching and straw burying. Considering the moisture conservation, soil salinity control and tomato yield, the combination of film mulching and straw burying was suggested for tomato cultivation in Ningxia Yanghuang irrigation area, the tomato yield increased by 13.65% and irrigation water saved by 23.08%, compared to the measure of no film mulching and no straw burying.
