| Abstract: |
| 【Objective】In order to determine the effect of circular multi-point source drip irrigation in rhizosphere,【Method】we studied the vertical distribution range of soil wetting front, soil moisture and yield of wolfberry under different irrigation method with surface drip irrigation, bubble irrigation and circular multi-point source root drip irrigation using soil core method in Shenmu county located in north Shaanxi province.【Result】The results showed that 69 % of soil wetting zone distributed in 0-20 cm soil layer in surface irrigation, 72.2 % distributed in main root layers in bubble irrigation, while the whole soil wetting zone distributed in main root layers in circular multi-point source root drip irrigation, respectively. The wolfberry yield had increased by 2075 kg/hm2, 3145 kg/hm2 and 4150 kg/hm2, water use efficiency had increased by 22.4 %, 41.9 % and 60.2 %, net income had increased by 81.2 %, 126.3 % and 193.1 %, water economic benefits had reached 11.5 RMB Y/m3,13.3 RMB Y/m3 and 15.0 RMB Y/m3 in surface drip irrigation, bubble irrigation and circular multi-point source root drip irrigation compared to without irrigation.【Conclusion】The soil moisture wetting volume of circular multi-point source root drip irrigation is more suitable for economic forest in sandy soil, it is an effective technical measure to reduce surface evaporation and deep percolation, and it could be applied widely in economic forest in sandy soil. |
