适时适量灌溉丰收高产苹果树根部吸收养分时需要水分把肥料溶化,供其吸收;在树体内部的二氧化碳形成光合作用时也需要水分;果树在空气中生长时也需要水分蒸发来调整树体温度;树叶中有60—80%的水分,果实内就有95%的水分。一棵树结一斤果实,就必须供给它十斤的水,保证苹果达到高额稳定的产量,就得进行合理灌溉。张家管理区利用龙口水库水进行灌溉,战胜了去年特有的大旱灾,实践证明灌溉次数多的,比灌溉少的长的好,产量高,由于适时灌溉密切结合其他农业措施,获得了高额的产量。灌溉方法是沟灌,就是在树行中间开引纵横引水渠道,水沿沟渠分布水流,以毛细管作用由沟的侧向渗入土壤,因而使大部土壤保持疏松,结构良好,地面湿润均匀,省工省水
Appropriate amount of irrigation High yield bumper Apple tree roots absorb nutrients need water to dissolve the fertilizer for its absorption; in the tree body of carbon dioxide to form photosynthesis when the need for water; fruit trees in the air also need water evaporation to adjust the temperature of the tree There are 60-80% moisture in the leaves and 95% moisture in the fruits. A tree a pound of fruit, it must supply it ten pounds of water, to ensure that Apple reached a high and stable yield, you have to be a reasonable irrigation. Zhangjiakou management area using Longkou reservoir water for irrigation, defeated last year’s unique drought, proved that irrigation more frequently than irrigation less long, high yield, due to timely irrigation in combination with other agricultural measures, access to high Production. Irrigation method is furrow irrigation, that is, in the middle of the tree line to open vertical and horizontal water diversion channels, water distribution along the ditch water flow to capillary the role of lateral infiltration of soil through the trench, so most of the soil remain loose, good structure, the ground moist and uniform, Save water
