高架式与地插式组合微喷灌效益的影响因子对比试验

The Comparison Experiment of the Benefit Effect Factors for the Combination of Frame Supported and Land Inserted Micro-sprinkler Irrigation

高架式与地插式组合微喷灌比较试验表明:喷头设置离地面高度2.5 m,不但给机械化耕作和生产作业营造了便利的操作空间,各项生产作业效率提高,而且不用埋铺管道,不破坏耕作层,检修方便。每667m2节省用工费52.5元,减少投资15.5元。

The result of comparison experiment using frame supported and land inserted micro-sprinkler irrigation shows that the perfect height of the sprinkler head is 2.5 m. It can provide easier space for the mechanized farming and the operation, and can improve the efficiency. There is no need to install the pipes to destroy the tillage layer in the soil, and the pipes are easier to repair. It can save 52.5 yuan of labor fees and reduce 15.5 yuan of cost per 667mz with this kind of method.
