Research on Micro-irrigation Method for Grown Red Jujube in Drought Area

The experiment was conducted to apply the most effective method of micro-irrigation such as drip irrigation,gush-spring irrigation and micro jet were field test according to the development demand of micro irrigation method for grown red jujube in drought area.From the yield,quality,physiological characters,root distribution and soil moisture etc regression analysis,it showed that micro jet was the optimum method of micro-irrigation for grown red jujube,and then drip irrigation,the worst was gush-spring irrigation.Compared with surface irrigation,the micro jet,three-drip irrigation and two-drip irrigation increased yield over ten percent and decreased irrigation quota over forty percent.And it was preliminarily identified that the optimal wet ratio irrigation of grown red jujube was forty to seventy percent,and the ratio of micro-irrigation was seventy percent and forty to fifty percent for drip irrigation.
