北方地区农田水利新技术探讨

Discussion on new technic in water conservancy of agriculture land in the North of China

针对我国北方地区水资源短缺、传统灌溉方法不相适应的状况,本文对农田灌溉技术的发展进行了分析后认为:加强正常年降水规律的研究、进行总水资源调控、推广雾层覆盖技术、增加田间林网、改善作物种植结构、推广多功能灌溉管道等是该地区农田灌溉技术发展的有效途径。

After analyzing the development of new technic in water conservancy of agriculture land in the North of China, where the traditional irrigation menthods has beeen unsuitable due to absence of water resource, it is pointed that to study law of rainfall in normal years, regulate and utilize the total water recource, develop fine spray irrigation, expend the forest belts in farmland areas, change the kinds of crops planted and applicate the multi-purpose irrigating pipe etc. should be the effective measures for saving water and increasing output of crops in the area.
