| 摘 要： | 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。

| Abstract: | Fertilizer machinery cannot easily pass through a close planting orchard, and the fertilizer utilization rate is low when using surface fertilizing. To solve this problem, quantitatively deep-fertilization method through placing granular fertilizer into dug holes was proposed. To put the method into practice, a small size fertilizer deep-applicator for orchards was designed, and its hole-digging performance was tested as well. The results showed that when the holes’ depth were 300, 350 and 400 mm respectively, the average diameter of the top of the holes were 207.7, 207.1 and 209.9 mm, the average diameter of the bottom of the holes were 206.3, 204.3 and 206.1 mm, and the average depth of the holes were 296.7, 345.9 and 395.4 mm, respectively. The errors of the holes’ diameter and depth were within 5 mm. And the digging efficiency was 34.5, 39.6 and 44.1 s, respectively, which could meet the requirements of hole-digging. The testing data provide a technical reference for the industrialization of fertilizer deep-applicator for orchards. |
