在农业生产中,水的问题应该包括发展水利和合理用水两个方面。可是水利部门责在发展水利,把水放到农田里就算基本上完成了任务,而剩下的合理用水问题,究应由谁承担下来?又如何才算合理的用水等一系列的问题,值得讨论研究。 就以新疆水利部门计算渠系有效利用系数平均为0.35来说,其意是说水从放水口经渠道进入农田,平均有35％的水被农业利用,一般也就认为这35％的水在农业上起到作用了,而实际上这35％的水真正被利用的还要打上几个折扣。因为农业生产中水分真正利用的效率,应该是指单位面积土地上,灌入的毛灌溉定额所实际获得到的作物产量
In agricultural production, water issues should include the development of water conservancy and rational use of water two aspects. However, the water conservancy department is responsible for the development of water conservancy, the water into the farmland even if basically completed the task, and the remaining reasonable water problems, who should bear down? And how to calculate a series of issues such as water, it is worth Discuss research. In terms of calculating the effective utilization coefficient of canal system in Xinjiang’s water resources department, the mean is 0.35, which means that water enters the farmland through the channel from the water outlet, with an average of 35% of the water being used by agriculture. Generally speaking, 35% Agriculture has played a role, but in fact this 35% of the water really have to use a few discounts. Because the efficiency of the true utilization of water in agricultural production should refer to the actual crop yield that can be obtained from gross irrigation quotas per unit area of land
