内蒙古翁牛特旗西高东低,海拔2000～3000m,该旗中、西部丘陵山区宜耕缓坡地占全旗总耕地的70％,过去靠高境方渠道灌溉,费水效益低。1987年进行爬坡管道输水灌溉试验成功。爬坡管灌,即“高压输水,低压灌溉”。整个系统由水源工程、输水系统、配水装置、保护装置几部份组成,具有节水、省地、增产、增收的特点,是山丘区脱贫致富的重要途径,深受群众欢迎,已推广25处4500亩。 以山咀子乡北山工程为例:水泵选用4B54A型,聚乙烯主管596m,7个出水口,灌地400亩;总投
Inner Mongolia Wenguiteqi West high East low, elevation 2000 ~ 3000m, the flag, the western hilly mountainous area of gentle slope accounted for 70% of the total cultivated land, in the past rely on high-level channel irrigation, water fee low benefit. 1987 Hill climbing pipeline water irrigation test successfully. Hill climbing irrigation, that is, “high-pressure water, low-pressure irrigation.” The whole system is composed of water source project, water delivery system, water distribution device and protection device. It has the characteristics of saving water, saving land, increasing production and increasing income. It is an important way to get rid of poverty in the hills and get rich. It is widely welcomed by the masses and promoted 25 at 4500 acres. To mountain Tsui Township Kitayama project as an example: pump selection 4B54A type, polyethylene supervisor 596m, 7 outlets, 400 acres of irrigated; total investment
