1发展集雨节灌所必备的条件集雨节灌是通过管道(或明渠)把地表水(或泉水)引向水池(水窖、水窑、水塘)等,然后再由管道向田间配水的灌溉形式,是雨水集蓄利用与节水灌溉的有机结合。近年来,这种形式也普遍应用于人畜饮水工程。发展集雨节灌工程必须具备以下条件:①水源较为可靠,平时集蓄,旱时灌溉。②水源较高。一般以高出下游地面10～30m为宜,保证能够自压灌溉。③具备一定的植被条件,及时清淤确保不致因淤塞而报废。
1 The necessary conditions for the development of rainwater harvesting Rainwater harvesting is the introduction of surface water (or spring water) to the ponds (cellars, water kilns, reservoirs) through pipes (or open channels), etc., and then to the fields The form of irrigation with water is an organic combination of rainwater harvesting and water saving irrigation. In recent years, this form is also widely used in drinking water projects. Rainwater harvesting and irrigation project must have the following conditions: ① water is more reliable, usually set savings, drought irrigation. ② higher water. Generally higher than the downstream ground 10 ~ 30m is appropriate to ensure self-pressure irrigation. ③ have certain vegetation conditions, timely dredging to ensure that will not be scrapped and scrapped.
