在毛主席革命路线指引下,我省平原沙荒的造林工作取得了显著成效,从而在一定程度上控制了风、沙灾害,保证了农业生产的稳产高产。但是,有的沙荒虽然造了林,至今却长不成材,如何改造这批“小老树”,成了我省林业战线上的一个大课题。据1970年统计,我省尚有宜林沙荒70余万亩,在这样大面积的沙荒上造林,树种的组成是值得重视的问题。 遵照毛主席关于“要认真总结经验”的教导,我们先后三次对平原沙荒造林问题进行了调查研究。结果表明,在沙荒条件下,营造混交林有很多好处:

The results show that there are many benefits to creating a mixed forest under desertification conditions:
