针对密植林果园机具通过性差,以及表层施肥的肥料利用率较低的难题,提出了将颗粒肥定量挖坑深施的施肥方法,围绕该方法,设计了一种小型果园肥料深施机,并对整机进行了挖坑性能验证试验。结果表明：挖坑深度在300、350、400 mm时的坑穴上口平均直径为207.7、207.1、209.9 mm,坑穴下口平均直径为206.3、204.3、206.1 mm;挖坑深度平均值为296.7、345.9、395.4 mm,坑穴直径误差5 mm以内,深度误差在5 mm以内;挖坑效率分别为34.5、39.6、44.1 s,能够满足挖坑要求;试验数据给果园肥料深施机的产业化提供了技术参考。

Fertilizer machinery cannot easily pass through a close planting orchard, and the fertilizer utilizationrate is low when using surface fertilizing. To solve this problem, quantitatively deep- fertilization methodthrough placing granular fertilizer into dug holes was proposed. To put the method into practice, a small sizefertilizer deep-applicator for orchards was designed, and its hole-digging performance was tested as well. Theresults showed that when the holes＇ depth were 300, 350 and 400 mm respectively, the average diameter of thetop of th...
