在宁夏干旱地区的中卫市沙漠日光温室乳瓜滴灌条件下,对膨润土、防渗沙、土工布、防渗板、苯板、塑膜+透气孔、底层黏土+侧膜、表层黏土和海绵9种不同耕作土壤防渗措施进行了对比试验。通过对株高、茎粗、叶面积指数、叶片数、含水率和产量的综合分析,得出较好的防渗措施是塑膜+透气孔、土工布和底层黏土+侧膜。
n the Conditions of cucumber drip irrigation desert greenhouse in Zhongwei of the arid region in Ningxia,the contrast experiment is taken on the nine different cultivated soil seepage measures such as bentonite,seepage control sand,geotextiles,watertight facing,polystyrene board,plastic film+ventilation holes,botton clay+side membrane,surface clay and sponge.This paper draws the conclusion that the best seepage control measures is plastic film+ventilation holes,geotextiles and bottom clay+side membrane through to the comprehensive analysis of plant height,stem diameter,leaf area index,leaf number,moisture content and yield.
