本文针对我国北方旱农区降水资源不足,造成的产量低而不稳状况,在研究作物产量与降水关系基础上,设计并较系统研究了提高降水利用效率的有效措施——沟植垄盖(膜)。多年、多点试验及示范结果表明:该措施使传统的间作套种与现代地膜覆盖技术相结合,改变了局部地形,形成了有利于作物生育的生态环境,增产及经济效益明显,是农业增产的一项先进种植技术。 In this paper, based on the study of the relationship between crop yield and precipitation, aiming at the lack of precipitation in the northern arid region of China, the effective measures to improve the efficiency of precipitation utilization are designed and systematically studied - membrane). The results of multi-year, multi-point experiment and demonstration show that this measure makes the traditional intercropping intercropping with the modern plastic film mulching technology, changes the local topography and forms the ecological environment conducive to crop growth with obvious yield increase and economic benefit, An advanced planting technique.
