摘要
在旱砂地造林中,为了提高造林效果,降低成本,采用了机械化挖穴。由于旱砂地的结构特殊,挖穴易造成砂土混合,降低砂田蓄水保墒性能,影响造林效果。因此,对挖穴规格进行了观察和分析,结果表明:规格为0.4 m×0.4 m×0.4 m的定植穴,效益高,成本低,工效高,造林成活率、保存率、3年生新梢生长量分别可达89.5%、88.0%、37.8 cm,宜在旱砂地造林中推广应用。
In order to improve the effect of afforestation and reduce cost, mechanized excavation was often adopted in drought sandyland. Because of the structural features of sandyland, the sand is easy to mix in the excavation process, sand field water storage is poor, and then affecting afforestation. So we observed and analyzed the excavation specifications, the results showed： The hole which is 0.4 m×0.4 m×0.4 m has high efficiency, low cost and high efficiency, and the survival rate, the retention rate and the growth of the new shoots in 3 years can reach 89.5% , 88.0% and 37.8 cm respectively. It is advisable to promote the application in the drought sandyland afforestation.
