宁河县稻田灌溉分为三种类型:(1)靠国家灌溉管理处及农场电力扬水站代水。(2)农业社用小型动力机提水。(3)畜力铁盘提水。一般情况下,电力扬水浪费大,每亩用水1,476立方;小型动力扬水次之,800—900立方;畜力铁盘最省,每亩仅用700—800立方。为了合理用水,提出如下的一些灌溉办法。一、在电力扬水灌溉区,主要是改变过去无计划、无限量给水,实行定时定量,轮流灌溉计划配水
There are three types of irrigation in paddy fields in Ninghe County: (1) Replacing water with the State Irrigation Management Office and farm electric pumping stations. (2) agricultural society with a small power machine to raise water. (3) animal iron plate to lift water. Under normal circumstances, a large waste of electricity pumped water, 1,476 cubic meters of water per mu; followed by small power plow, 800-900 cubic meters; animal power iron plate most provinces, only 700-800 cubic meters per mu. In order to use water rationally, some of the following irrigation methods are proposed. First, in the electric pumping irrigation area, mainly to change the past without plans, unlimited water supply, the implementation of regular quantitative, irrigation schedule irrigation
