红松果材兼用林混交模式的试验研究

Experiments on mixed models of seed-timber stands of Pinus koraiensis

对红松果材兼用林造林混交模式的试验研究结果表明,采取红松与日本落叶松隔行混交造林,当日本落叶松达到工艺商品市场价值时,一次性采伐后,可收回投资成本,并获取较好利润,从而缩短投资周期,解决了营林生产中存在的红松结实前期无产出效益的实际问题。

Experiments on mixed models of seed-timber stands of Pinus koraiensis was conducted in this paper. The results indicated that: Planting Pinus koraiensis and Larix Kaempferii mixed stands by line and when Larix Kaempferii reached technical commercial values and was cut over, investment could be got back and better profits be obtained. Thus, investment cycle was shortened, and the existing issues in production, namely, no benefit was obtained before Pinus koraiensis bore seeds was resolved.
