摘要
针对干旱区红枣微灌技术发展需求，采用目前最常用的滴灌、涌泉灌、微喷灌三种微灌技术进行田间试验，从产量、品质、生理性状、根系分布及土壤水分状况分析表明，微喷是成龄红枣最适宜的微灌技术形式，其次为滴灌，涌泉灌的效益最差，其中微喷、滴灌三管、滴灌双管处理与地面灌相比，均能增产10％以上，减少灌溉定额40％以上。同时初步确定成龄红枣微灌适宜湿润比为40％～70％。微喷灌采用70％的湿润比，滴灌采用40％-50％的湿润比效果较佳。
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.
