摘要
通过开展沙地地下灌溉实验研究,提出了在灌水器下方铺设35 cm×35 cm不透水膜的灌溉方法,将地下灌溉技术应用于沙地,研制开发的新型灌水器,具有所需水头低、低成本的特点,突破了灌水器孔径小于0.7mm的堵塞敏感尺寸,有效减低了灌水器堵塞问题,为治理利用沙地资源提供了灌溉保证。
A new type of douche was developed, having the characteristic of low flow peak and low cost, which broke blockade sensitive size of douche bore diameter less than 0.7 mm, and reduced douche blockade problem efficaciously. Through developing the research of sands underground irrigation experiment, irrigation method of paving 35 cm × 35 cm water proof membrane under the douche was put forward, also underground irrigation technique was applied in sands, which provided guarantee to harness and utilize sands resources.
