@@@@通过2年对果树环绕滴灌施肥与畦田灌冲施肥的效果研究表明，苹果采用环绕滴灌施肥技术具有很大的节水增产潜力，在比畦灌对照节约灌水37%、节约纯养分7%～15%的条件下，产量增加34.1%～45.1%，水分利用效率增加1.2～1.5 kg/m3，滴施“圣诞树”水溶肥处理的果实品质明显提高。因此，在果树生产中推荐采用环绕滴灌施肥，萌芽期滴施水溶肥(20-20-20)11 kg/667 m2、果实膨大前期滴施(19-8-27)20 kg/667 m2、膨大后期滴施(16-8-34)20 kg/667 m2，每次灌水30～35 m3/667 m2，可获较高的产量和水分利用效率。

Effects of surround drip fertigation with two different water-soluble fertilizers (“Batian”, and“Christmas tree”) on yield and quality of apple compared with CK (conventional border irrigation) was studied for two years. The results indicated surround drip irrigation has many priority compared with CK. It saved 37%of water and 4~15%of nutrient, while increased yield by 34.1~45.1%, and increased water use efficiency by 1.2~1.5 kg/m3.”Christmas tree”fertilizer increased the quality of apple too.So we suggested surround drip irrigation with soluble fertilizer in apple production. At the stages of germination, the early and late days of fruit expansion period, the soluble fertilizer of 11 kg/667 m2, 20 kg/667 m2 , 20 kg/667 m2 can be applied with drip irrigation of 30 ~ 35 m3/667 m2 respectively. Then high yield and high water use efficiency can be got.
