摘　　要：利用水量平衡原理,对肥城市潮泉镇苹果园春季典型月份果园水分的收入与支出情况进行分析,确定其果园水分的亏缺与盈余状况,从而制定相应的灌溉措施。通过典型月份和花期2个时间段的水分平衡状况进行研究,试验结果表明,在不进行任何形式灌溉的情况下,典型月份果园水分总体上处于亏缺状态,水分的亏缺量为19mm。典型月份日均蒸腾量为1.86mm;花期日均蒸腾量为1.97mm,花期内水分消耗量要更明显一些。Using the water balance principle,analyze the situation of income and outcome of soil moisture on the Apple orchard in Chaoquan of Feicheng,4 month,and determine the situation of soil moisture deficit and surplus,then formulate the corresponding irrigation measures.From the experiment,we can see the soil moisture is in the lack of state in general without any form of irrigation,in the April the number of moisture deficit are almost 19 mm.And compared with other stage,the key period of fruit trees is lack of water more obvious.

关 键 词：果园 水量平衡 水分收入 水分支出
