Abstract:
      This study aimes to investigate the effect of drip discharge on the characteristic value of wetting soil in Jujube demonstration base of Xinjiang Academy of Forestry Sciences, and elucidate the fruit industry in daily management of drip flow. The result shows that the size of wetting soil increased with increasing of drip flow, the wetting front distance in direction of horizontal and vertical increased as well; wetting front migration rate, infiltration distance and water infiltration time followed power function relationship; the wetting front migration rate in horizontal is larger than vertical while migration time is shorter than that in vertical; soil moisture content increased with increasing of drip flow, drip distance influenced moisture content, the moisture content reached maximum below drip 40 cm and q≥8 L·h-1.
