随着工农业生产的发展和城市生活用水的不断增加,水资源的供需矛后日益突出。特别是在连续干旱的情况下,地下水大幅度下降,给机井灌溉带来了水源不足、能源紧张的困难。因此,研究推广节水节能的输水灌溉技术,改进灌溉渠系,提高灌溉水利用率是灌溉工作的当务之急。为此,我们在汶上、东平县四口单井(控制灌溉面积300亩),采用了半固定管道输水灌溉,进行了观测试验。机井地区的输水灌溉渠系,一般分为干 With the development of industrial and agricultural production and the increasing use of urban domestic water, the supply and demand of water resources have become increasingly prominent. Especially in the case of successive droughts, the groundwater drastically dropped, which brought about the shortage of water resources and the energy shortage caused by irrigation. Therefore, it is imperative to study and promote water-saving and water-saving irrigation technology, improve irrigation canal system and improve irrigation water utilization rate. To this end, we have conducted a series of observation and experiments in a single well (controlled irrigated area of ​​300 mu) in Wenshang and Dongping counties using semi-fixed pipelines. Grouting irrigation canal system, generally divided into dry
