摘　　要： 选用不同颜色地膜,在大田条件下,采用全膜覆盖垄上侧播栽培方式,研究了不同覆膜颜色对旱地土壤水热效应和马铃薯产量的影响。结果表明,土壤含水率变化受覆膜、降雨量和马铃薯生长的影响,膜色对土壤温度影响较大。绿膜增产效果最显著,较白膜和黑膜分别增加了7.2%和3.5%。为了增加土壤保温保墒能力,提高马铃薯产量,推荐陇中旱作马铃薯生产中采用绿色全膜垄作侧播栽培模式。 From field experiments, the different colors of plastic films were selected to study the effects of differ- ent mulch colors on dry land soil water, temperature and yield of potato using the full film overlay on the side of the ridge sowing cultivation methods. The results showed that the change of soil moisture content was affected by film covering, rainfall and potato growth. Green film was the most contribute to the yield, and the yield increased by 7.2% and 3.5% compared to white and black film, respectively. In order to increase soil water content and the yield of potato, it is suggested to use green film ridge side planting cultivation mode in the middle of Gansu prov- ince dry land potato yield.
