近几年来,造林经验证明,油松雨季造林是辽宁西部干旱地区的一种成功的造林方法,只要掌握天气有利时机和造林各项技术环节,可以获得稳定而较好的造林成果。如锦州虹螺山林场油松雨季造林(不灌水),1961年造林平均成活率为70.1%,1962年为78.2%(1963年5月调查),春季造林(灌水)仅49.5%。
In recent years, afforestation experience proves that afforestation of Pinus tabulaeformis rainy season is a successful afforestation method in the arid region of western Liaoning. Only by grasping weather favorable opportunity and afforestation techniques can obtain stable and good afforestation results. For instance, the afforestation afforestation (irrigated) of Pinus tabulaeformis forests in Hongluoshan Forest Farm, Jinzhou, achieved an average survival rate of 70.1% in 1961, 78.2% in 1962 (May 1963 survey) and only 49.5% in afforestation (irrigation) in spring.
