中文摘要: 旱作地膜小麦-玉米带田一膜两用技术热效应显著,可提高地温2—6℃,保证了小麦安全越冬,促进了作物早发;热资源利用率高达0.977,比单作提高了25%-40%;变作物一年一熟为一年两熟,亩产可达到440—610kg,比单作增产20%-80%.

Abstract:The heat efficiency of one film in dry farming fields of wheat and corn is studied. It suggests that with the application of this plastic film,the soiltemperature could increase about 2-6℃ thus provided a favorable condition to the growth of winter-wheat .with a heat efficiency of 0. 997.Compared with that of single croping the heat efficiency has been raised by 24%-40%. And therefore one crop a year became two crOP a year. Per mu yield is about 440-610kg and compared with that of single croping it increased by 20%-80%.
