去年,我省果树滴灌面积已发展到1.5万亩,主要滴灌苹果、梨、桃、葡萄,核桃等;取得了显著的节水增产效果.实践证明,要使滴灌系统充分发挥效益,首先应搞好滴灌区的规划设计.根据我省具体情况,果树固定式滴灌系统规划设计,应掌握以下原则:1.经济合理设计干、支管径,随着管路所需流量递减的规律,干、支管采取根据流量分段设计,形成由粗变细的变径管路系统,以降低管材的投资.
Last year, the province’s drip irrigation area of fruit trees has been developed to 15,000 mu, the main drip irrigation apples, pears, peaches, grapes, walnuts, etc .; achieved significant water yield and increase efficiency. Practice has proved that to make full use of drip irrigation system benefits, we must first engage Good drip irrigation district planning and design.According to the specific situation in our province, the fixed tree drip irrigation system planning and design, should have the following principles: 1. Economically rational design of dry, branch diameter, with the flow of the pipeline diminishing law, dry, Branch pipe according to the flow segment design, the formation of the thickening of the pipe system to reduce the pipe to reduce investment.
