摘　　要：通过大田试验,采用相同的灌溉制度,研究了滴灌和微喷两种灌溉方式对成龄核桃树耗水量、产量及坚果品质的影响。试验结果表明:①滴灌条件下核桃树在萌芽及开花期、果实膨大期、硬核期及成熟期的平均日耗水强度分别为2.9 mm、3.97 mm5、.55 mm及3.39 mm,微喷核桃树的耗水规律与滴灌略有不同,果实膨大期及成熟期稍大;两者的累积耗水量相同。②滴灌的平均水分利用效率比微喷高,滴灌的产量比微喷高15%。③两种灌溉方式下,滴灌核桃蛋白质含量、出仁率均较微喷高,其他指标无明显差异。Field experiment was conducted to study the effect of drip irrigation and micro-sprinkler irrigation on Water Consumption,Yields and Quality of aged Walnut trees,which used the same irrigation schedule.The experiment results showed：①Under the condition of drip irrigation,the average of daily water consumption in blooming stage,fruit accelerated growth stage crust stage and maturity stage were 2.9mm,3.97mm,5.55mm and 3.39mm respectively.Water consumption of micro-sprinkler irrigation was different from drip irrigation,but in fruit accelerated growth stage and maturity stage the cumulation of water consumption of Both irrigations had no difference.②The water use efficiency of drip irrigation was about 15% higher than micro-sprinkler irrigation.The yield of drip irrigation was higher than that of sprinkler irrigation.③Under the condition of two Irrigation methods,the content of protein of drip irrigation was higher than micro-sprinkler irrigation and as same as the ratio of bared kernel.Other indexes made no difference.
