根据近几年来在我区各地调查和群众的经验,林粮间作的好处确实很多,但其中以间种豆类作物为最好。首先,造林当年就有直接的经济收益。例如凉城县三苏木人氏公社集一管理区1957年在面积约300亩黄土斜坡幼林地内间种农作物,当年就有价值250元的收入;1958年继续在800亩幼林地内间种农作物,又收入1,000元。现在林粮间作已成为当地农民对林业生产的习惯了。
According to the surveys conducted in various parts of our region in recent years and the experience of the masses, there are indeed many benefits of intercropping of forest and grain crops, but among them, the best is the inter-species legumes. First of all, there is a direct economic gain in the afforestation year. For example, the collective management area of the Sanmu Muzi Commune in Liangcheng County started to plant crops in the young forest with an area of about 300 mu on a loess slope in 1957, with a total annual income of 250 yuan. In 1958, 800 acres of young forest land continued to grow crops, Revenue of 1,000 yuan. Now intercropping has become a habit of local farmers for forestry production.
