将痕量灌溉、微润灌溉与常规滴灌进行试验对比,目的是掌握这些新型节水灌溉设备的节水效果,摸索其工作时适合的技术参数(工作压力、埋带深度和出水量),了解其综合性能(耐用性、省力程度和能耗),为以后节水灌溉设备的更新运用以及根据农作物的不同要求建立不同的节水灌溉模式提供基础性材料,便于农业技术推广和相关技术的改进。
Comparison of trace irrigation, micro-irrigation and conventional drip irrigation experiments, the purpose is to master the water-saving effect of these new water-saving irrigation equipment to explore the appropriate technical parameters of their work (working pressure, buried with the depth and the amount of water) to understand Its comprehensive performance (durability, labor-saving and energy consumption) provides the basic materials for the later application of water-saving irrigation equipment and establishment of different water-saving irrigation modes according to the different requirements of crops, so as to facilitate the popularization of agricultural technology and the improvement of related technologies .
