1980年从黑龙江省东部的密山引进兴凯湖松(Pinusussuriensis)种子,在错海林场播种育苗,1982年春造林。14年的弓1种实践证明,兴凯湖松在黑龙江省西部干旱、半干旱、土质瘠薄、岩石裸露的山地上造林表现出较强的适应性和旺盛的生长力;10年生时开始结实;14年生时其平均树高、胸径、单株材积和公顷蓄积量分别达到4.77m、8.02cm、0.0140m ̄3和32.9m ̄3,比同龄的子松分别大22.9%、33.4%、72.8%和74.1%;经分析,两树种各因子差异均达极显著水平;经预测,在18年生时,兴凯湖松的公顷蓄积量将是樟子松的2倍以上;为我省西部地区增添了一个新的造林适生树种。
In 1980, Pinusussuriensis seeds were introduced from Mishan in the eastern part of Heilongjiang Province, nursery plants were planted in the wrong sea forest and reforested in the spring of 1982. A practice of 14 years shows that Xingkaihu pine shows strong adaptability and vigorous growth force in the arid, semi-arid, infertile soil and rock-bare mountain in western Heilongjiang Province. At 14 years of age, the average tree height, DBH, stand volume and hectare reached 4.77m, 8.02cm, 0.0140m ~ 3 and 32.9m ~ 3 respectively, which were 22.9% , 33.4%, 72.8% and 74.1% respectively. After analysis, the difference of each factor between the two species reached extremely significant level. It is predicted that the stock volume of hectare of Xingkaihu pine would be Pinus sylvestris Pine more than 2 times; for the western region of our province added a new afforestation tree species.
