当前我省不少地区对水的利用率还不高,一般尚达不到30％。一个水仅浇地4—5万亩。分析原因,主要是没有充分利用水源。灌溉渠道不系统,工程不成套,组织不健全,浇地制度不严,渠道渗漏严重等也是重要原因。这样不仅浪费了水量,而且抬高了地下水位,招致土壤盐碱化,对农业生产很不利。因此必须改变这种现象,提高水的利用率,扩大灌溉效益。根据翼城利民渠、汾阳峪道河、繁峙茂河等灌区一个水现已浇地10万至11万亩的灌溉经验,主要有以下几点:一、日夜不停浇地。峪道河灌区不论冬、春,刮风、下小雨,白天、黑夜,决不让水白流。下小雨时低地不浇,高地浇,在冬、春灌溉时,冬至前先浇小麦,上冻后再浇秋地。在夏收复播时,还采取了边收割、边灌溉、边复播的办法。使水全年点滴入田。达到了充分利用水源,提高了水的利用率。
At present, the utilization rate of water in many areas of our province is not high, generally less than 30%. A water only irrigated 4-5 acres. Analysis of the reasons, mainly did not make full use of water. Irrigation channels are not systematic, project is not complete, the organization is not perfect, lax irrigation system, serious channel leakage is also an important reason. This not only wastes the water quantity, but also raises the underground water level, causes the soil salinization, is very unfavorable to the agricultural production. Therefore, we must change this phenomenon, improve water utilization and increase irrigation efficiency. According to the Yicheng Limin canal, Fenyangyu Road, Fanzhi Mao River and other irrigation areas have now been irrigated to 100,000 to 11 acres of irrigation experience, mainly in the following points: a day and night irrigated. Yu Road Irrigation regardless of winter, spring, windy, light rain, day and night, never let the water flow. In the light of the lowlands are not irrigated, high ground water, in winter and spring irrigation, before the winter solstice pouring wheat, frozen and then poured autumn. In the summer harvest, it also took the side of the harvest, while irrigation, while the method of replay. Make the water drip into the field throughout the year. Reached the full use of water, improve water utilization.
