河北省水资源严重不足,已成为工农业生产发展的制约因素,农业是用水大户,麦田灌溉又是农业用水的大户。因此,研究冬小麦的节水灌溉措施,对缓和水资源供需矛盾,提高灌溉效益,有着十分重要的意义。过去冬小麦的灌溉制度,多在正常灌溉条件下,通过总结群众经验、结合灌溉试验来确定。对水资源短缺,非正常灌溉条件下如何进行节水灌溉研究较少。近年来,临西、藁城灌溉试验站进行了不同灌水次数和水量的对比试验,为调整不同类型地区的冬小麦灌溉制度,提供了依据。现根据藁城、临西两灌溉试验站多年试验结果,对冬小麦节水灌溉制度提出以下意见。
A serious shortage of water resources in Hebei Province, has become a factor in the development of industrial and agricultural production constraints, agriculture is a large household water, wheat irrigation is a large agricultural water. Therefore, studying the water-saving irrigation measures of winter wheat is very important for alleviating the contradiction between supply and demand of water resources and increasing irrigation benefits. The past winter wheat irrigation system, mostly in normal irrigation conditions, by summing up the masses experience, combined with irrigation experiments to determine. There are few researches on how to carry out water saving irrigation under the condition of water shortage and non-normal irrigation. In recent years, the Provisional West and Yuncheng Irrigation Experimental Station carried out comparative tests of different irrigation times and water volumes, which provided the basis for adjusting the irrigation system of winter wheat in different types of areas. Now based on Tancheng, Linxi two irrigation stations for many years test results, the winter wheat water-saving irrigation system, the following comments.
