低压下加肥对迷宫滴头流量及灌水均匀度的影响
Influence of injected fertilization under low pressure on dripper discharge and uniformity coefficient
摘要
Abstract
To address the concerns about dripper discharge , uniformity coefficient , and blockage of flanking labyrinth drip tape ,a series of experiments were carried out to test the effects of clear water and fertilizer water on the u-niformity coefficient and blockage of the dripper discharge .The results showed that dripper discharge became less with the injection of fertilizer water than clear water ,as well as the uniformity coefficient ,which was reduced by 5% ~9% in four drippers with different structures .With the increases of irrigation time intervals and frequencies ,the blockage degree of drip irrigation will increase due to the crystallization of chemicals in water .Different structures of the drip irrigation tape had different effects on the degree of blockage .关键词
