通过田间试验研究了双垄全膜覆盖沟灌、条膜平铺覆盖和露地栽培马铃薯的土壤温度、水分的变化。结果表明:双垄全膜覆盖沟灌模式较条膜平铺覆盖栽培增产38.66%,较露地栽培增产99.02%;水分利用效率较二者提高了45.91%和124.48%;马铃薯苗期0~20cm土层地温垄上部位较地膜平铺增加0.25℃~0.7℃,较露地栽培增加5.4℃~8.3℃;沟内地温较地膜平铺降低1.2℃~2.1℃,较露地栽培增加3.0℃~5.9℃。
Field experiments were conducted to study the changes of soil temperature and water content in double-ridge full-film mulching, strip-tiling and open-field cultivation of potatoes. The results showed that the double-ridge mulch film mulching irrigation mode increased the yield by 38.66% compared with the film mulching cultivation, and increased the yield by 99.02% compared with the open field cultivation. The water use efficiency increased by 45.91% and 124.48% The top of the ground temperature ridge increased 0.25 ℃ ~ 0.7 ℃ compared with the film tiling, increased 5.4 ℃ ~ 8.3 ℃ compared with the open field cultivation. The ground temperature in the trench decreased 1.2 ℃ ~ 2.1 ℃, 3.0 ℃ ~ 5.9 ℃ higher than the open field cultivation.
