一、试验目的和意义 节水型农业是灌溉科学发展的方向。开发大西北研究节水技术比开发水资源有更大意义。喷滴灌节水技术开始在密植作物和园林生产中发挥作用,中耕作物和瓜菜正广泛运用塑料薄膜栽培。本试验的目的是在地膜栽培的基础上,进一步利用地膜输水防渗并通过放苗孔渗水实现节水灌溉,探索其节水程度和地膜灌水技术,以及由此引起的生态环境变化和对投入产出的影响,以期开发出一种适合中耕作物,投资少、见效快、易推广、效益高的节水新技术。
First, the purpose and significance of experiments Water-saving agriculture is the direction of scientific development of irrigation. It is more significant to develop water-saving technologies in Northwest China than to develop water resources. Spray drip irrigation and water-saving technology began to play a role in the dense planting of crops and garden production, cultivating crops and vegetables are widely used plastic film cultivation. The purpose of this experiment is based on the cultivation of plastic film, the further use of plastic film impermeable water seepage and water seepage through the Fangmiao hole to achieve water-saving irrigation to explore the degree of water-saving and plastic film irrigation technology, and the resulting changes in the ecological environment and Input and output impact, in order to develop a suitable for cultivating crops, less investment, quick, easy to promote, high efficiency of water-saving new technology.
