目前安徽濉溪县全县有效灌溉面积已达56万亩,接近耕地面积30％,随着工农业生产水平的提高,水源日趋紧缺。我们从1975年起,开始研究试验节水型灌溉。由点到面,逐步推广,从1985年开始,共使用喷灌贴息贷款52万元,发展喷灌面积4.2万亩,目前全县有节水型灌溉面积27万亩,其中喷灌26.2万亩,管灌0.8万亩。
At present, the effective irrigated area of Taixi County in Anhui Province has reached 56 million mu, which is close to 30% of the cultivated land area. With the improvement of industrial and agricultural production level, water sources are increasingly scarce. Since 1975, we started to study and experiment on water-saving irrigation. From point to surface, and gradually promote, from 1985 onwards, a total of 520,000 yuan to use sprinkler interest-subsidy loans, the development of sprinkler area of 42,000 mu, the county has a water-saving irrigation area of 27 mu, of which irrigation 262,000 mu, pipe irrigation 0.8 million mu.
