我场现有林地面积11万亩,其中人工林7万亩。建场初期造林树种比较单一,绝大部分是落叶松和油松(Pinus tabulaeformis),而红松(P.koraiensis sieb ec zucc)比重甚小。其原因是认识不足,认为红松虽然材质优良,用途广,但生长慢,对立地条件要求严,而且成材晚,收益慢。红松生长是否缓慢,对立地条件要求如何?我们就这个问题于1965年开始进行了试验。通过试验已取得了成效,并逐年扩大了红松造林范围。现已营造红松林2.5万亩,目前已郁闭成林, My field of existing 11 million mu of forest land, of which 70000 acres of plantations. In the early stage of afforestation, afforestation species were relatively simple, mostly larch and Pinus tabulaeformis, and P. koraiensis sieb ec zucc had a small proportion. The reason is lack of understanding, that although the material is good, widely used, but slow growth, strict conditions on the opposition, and become late, income slow. Whether the growth of Korean pine is slow or not depends on the condition of the site. We started the experiment on this issue in 1965. The results have been achieved through experiments and the area of ​​Korean pine plantation has been expanded year by year. Has now created 25000 acres of Korean pine, now closed forest,
