在造林中,一些精耕细作的方法(需要很多的时间和费用)不一定都有优越性,特别是在结构良好的土壤上这种方法根本没有优越性。相反,一些简单易作而又能兼顾经济和生物学特点的造林方法如莱辛格尔角形植树法却是完全合乎要求的。否定这些方法,就会妨碍技术的进步。这种简易方法有两个优点:一个优点是由于提高了劳动生产率,可以缓和早春造林时劳动力紧张的现象;另一个优点是由于进行局部的 In afforestation, some methods of intensive farming (which require a lot of time and money) do not necessarily have advantages, especially in well-soiled soils that there is no advantage at all. On the contrary, some afforestation methods that are simple and easy to work with both economic and biological characteristics, such as the Lesotho angle tree planting method, are perfectly satisfactory. Denying these methods will hinder the progress of technology. This simple method has two advantages. One advantage is that due to the increased labor productivity, it can alleviate the labor shortage in early spring afforestation. Another advantage is that due to the local
