Field plot experiments were employed to investigate soil water and soil temperature effects of ridge furrow of peanut under film mulching,liquid film mulching,and straw mulching. Remarkably reduced evaporation was found under the three mulching techniques. Compared to 0—30 cm soil layer,the soil moisture contents after irrigation under the three kinds of plant cover and bare ground were increased by 67.35%,35.44%,and 5.1%,respectively. Film mulching significantly increased soil temperature of peanut root zone. Straw mulch cover material hindered the sun's direct radiation on the surface. Compared to bare land,soil temperature in 0—25 cm root zone was reduced by 1.3 ℃～5.5 ℃. Mulching increased product as high as 167.07%.
