Abstract
Drip irrigation is one of the efficient method, that, in recent years, it is widely used in Iran agriculture. But the use of low quality waters caused problems in this system. Physical clogging of emitters is the most important of these problems. Emitters clogging reduce Irrigation efficiency and drip irrigation system lifetime. Entry of Suspended and physical particles into the emitter is the most important factor of emitters clogging and reducing the discharge rate of there. On the other hand, various factors such as water temperature affect the discharge rate and clogging of emitters. The objective of this study was to investigate the effect of temperature on the anti-clogging performance of the long path emitters. For this purpose by constructing an Experimental physical model and the use of sand grain with different sizes and concentrations, the anti-clogging performance of seamed and seamless irrigation tapes and Emitting pipe was studied at temperatures of 13, 23, 33, and 43 °C. The results show that raising the temperature has a positive effect on reducing of the clogging emitters. The results also showed that the Emitting pipe and seamed irrigation tape have the minimum and maximum clogging rate , respectively. Also, the uniformity coefficient of emitting pipe and seamless irrigation tape was greater than 90 percent in all circumstances. . Statistical analysis showed that the effect of temperature on the clogging rate of emitters is significant at one percent level.
