湖北省垦区多属低洼平原湖区 ,灌排矛盾相当突出 ,灌溉建设亦呈现多样化趋势 ,针对这一实际情况 ,各农场作了长时间的探索。随着近十年来国家农业综合开发的项目实施 ,从砖砌预制块、混凝土衬砌 ,发展到低压涵管灌渠 ,这种低压涵管灌渠越来越显现出其优越性。为此 ,对湖北垦区这种灌溉输水方式进行了实例分析计算。 Most of the reclamation areas in Hubei Province belong to the low lying plain plain lake area, and the contradiction between irrigation and drainage is quite prominent. The irrigated construction also shows a diversified trend. In view of this actual situation, the farms have made long-term exploration. With the implementation of the project of comprehensive national agricultural development in the recent ten years, such low-pressure culvert ditches have shown their advantages more and more from prefabricated blocks and concrete linings to low-pressure culvert ditches. To this end, Hubei Irrigation District of this irrigation water for example analysis.
