| 摘 要： | 为了弄清黑膜在马铃薯覆盖栽培中的温度动态、水分动态变化和对马铃薯产量形成的影响，对黑色膜及不同覆盖方式对马铃薯产量效应进行了研究。结果表明，马铃薯块茎形成期黑膜比白膜0-20cm地温降低1—2℃，增产22．17％，降水利用率提高了8％。为大面积应用提供科学依据。

| Abstract: | To detect dynamic variation of temperature, moisture and influence on potato yield of black film covering on potato yield, effect on black film and different covering ways on potato yield was studied. The study showed that 0-20 cm ground temperature of black membrane reduced 1-2 ℃ than white membrane, and the production increased by 22.17% and precipitation utilization ratio increased by 8%. The study provided a scientific basis for the widespread application. |
