摘要:
为探究南疆枣树花期适宜的灌溉量，以近几年品质退化较为严重的骏枣为对象，分析了开花坐果期不同处理对土壤水分动态变化及光合作用的影响。结果表明：滴灌条件下骏枣园土壤深度40~60 cm的含水量恒定控制在田间最大持水量的65%左右是保证根系富集区土壤水分供应能力的关键，此时叶片的净光合效率和水分利用效率最高，是适宜南疆地区骏枣盛花期叶片进行光合作用的水分管理措施，可实现骏枣营养生长向生殖生长的快速有效转换，提早坐果时间，延长果实生育期，提升品质的目标。
Abstract:
In order to study the appropriate irrigation volume on jujube tree under drip irrigation in South Xinjiang,this paper analyzed different water index lower limit on influence of soil moisture dynamic change and photosynthesis in blossoming and bearing fruits stage of Jun jujube,which the quality degradation is more serious in recent years.The results showed that it was the key to ensure deliverability of soil moisture near the radication descending axis enrichment region,when it was controlled for the constant volume water content between 40 cm and 60 cm in soil depth at about 65% of the maximum field water capacity in Jun jujube garden under the condition of drip irrigation.By this time,it was found that the leaves had the highest Pn and WUE,it was suitable water management measures for photosynthesis in leaves of Jun jujube in southern Xinjiang,it was realized aim of the rapid and effective transformation from vegetative growth to reproductive growth,antedated fruit setting time,prolonged fruit growth period and improved fruit quality.
