Study on the Technical Parameters of Micro-moist Irrigation

ZHANG Zhaohui;ZHANG Jiangui;XU Baoshan;Gansu Shule River Basin Water Authority;  
With the micro-moist pipe for the test material,the exposed and buried treatments were designed to study laying reasonable length,the average flow and the soil moisture distribution under different soil textures and pressures.The results showed that,under different soil textures,there was a linear relationship between the flow and micro-moist pipe pressure,both the flow per unit length and laying reasonable length increased with the increase of micro-moist pipe pressure.Under the experimental conditions,the steady soil water content was 18%~21% around micro-moist pipe in buried treatment,which was 70%~90% of field capacity,indicating that the spacing of 60 cm was the more reasonable layout.
