一、发展微积水节灌所必备的条件微积水节灌是通过管道把地表水(或泉水)引向水池(水窖、水室、水塘)等,然后再由管道通向田间配水的灌溉形式,是把小量的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。发展微积水节灌工程必须具备以下条件:水源较为可靠,平时集蓄,旱时灌溉;水源较高,一般以高出下游地面10~30m为宜,保证能够自压喷灌;具备一定的植被条件,使工程不致因淤塞而报废。
First, the development of the necessary conditions for hydrocephalus irrigation Hydrocephalus irrigation is through the pipeline to the surface water (or spring) to the pool (cellar, water chamber, reservoir), and then from the pipeline leading to the field Irrigation water distribution, is a small amount of water collection and use of water-saving irrigation and organic combination. In recent years, this form is also widely used in drinking water projects. The development of hydrophylic irrigation project must have the following conditions: water is more reliable, usually set savings, drought irrigation; high water, generally higher than the downstream 10 ~ 30m is appropriate to ensure that pressure irrigation; have a certain vegetation Conditions so that the project will not be scrapped and discarded.
