1.穴贮肥水: 在特别瘠薄干旱的山地果园,为保持土壤水分和增加土壤肥力,可采用穴贮肥水的栽培技术。此技术无地膜覆盖的根系上浮和肥力损失较快的弊端,为根系创造了一个水分充足,养分富集,透气良好的局部环境,穴的周围新根密集,活动旺盛。穴贮肥水可提高土壤含水量40％以上,基本满足地上部梢、叶、花、果生长的需要。此方法节约肥水,一般可增产30％以上,在干旱瘠薄的果园有推广价值。
1. Hole storage fertilizer: In particularly infertile mountainous orchards, in order to maintain soil moisture and increase soil fertility, can be used hole storage fertilizer cultivation techniques. This technique has the disadvantages of floating and losing fertility in the root system with no mulching and creating a local environment rich in water, rich in nutrients and good in air permeability. Storage of potable water can increase the soil moisture content of 40% or more, basically meet the aboveground shoots, leaves, flowers, fruit growth needs. This method saves fertilizer and water, generally increase yield by more than 30%, and promote the value in arid orchards.
