一、平整土地。根据试验，耕地不平的，每亩每次需灌水80立方；耕地平整的，每亩每次只需灌水30立方。二、修好渠道。修好渠可减少渠道渗漏，保持渠道畅通，一般可节约灌溉用水30％－50％。三、薄膜防法。如采取圆筒形塑料膜铺渠，水的利用率可达到90％以上c四、小畦灌溉。短畦 First, the formation of land. According to the test, uneven arable land needs 80 cubic meters of irrigation water per acre; for arable land, 30 cubic meters of water per acre need to be poured. Second, repair channels. Drainage canal can be reduced to reduce channel leakage, keep the channel open, the general savings of irrigation water 30% -50%. Third, anti-film law. Such as the cylindrical plastic film pavement, water utilization rate can reach 90% c four small 畦 irrigation. Short 畦
