摘要
为了探讨我国辽西半干旱地区油松造林适宜的立地条件,开展了不同的坡位、坡向、坡度、土层厚度下油松造林比较试验,结果表明,不同的立地条件可不同程度地影响油松造林后的成活及生长情况,整体来说以坡位为中上坡以上、坡度为20°～30°、土层深厚的阳坡上实施油松造林可取得较好的效果。
In order to explore the suitable site conditions for afforestation of Pinus tabuliformis in the semi-arid areas of western Liaoning Province,a comparative experiment on the growth of Pinus tabuliformis under different slope position,slope direction,thickness of soil layer and thickness of soil layer is arranged in 2017.Result shows that different site conditions can affect the survival rate and growth of Pinus tabuliformis after different afforestation.In general,afforestation of Pinus tabuliformis which were planted on the sunny slope +slope position being above the upper slopes + the slope being 20-30° can achieve optimal efficiency.
