采用7、10、11和16个月生的湿加松无性系扦插苗造林,对造林成活率及5年生时的保存率和生长量调查分析结果显示:湿加松的成活和保存率比湿地松略低,但生长量明显大于湿地松,说明湿加松生长优势明显,有较大的推广价值;4种苗龄的湿加松无性系苗造林效果比较,10、11和16个月苗龄的湿加松苗造林后的成活率、保存率和生长量均显著优于7个月苗龄的湿加松苗。综合考虑育苗成本和造林效果,认为采用10或11个月苗龄的扦插苗造林效果好。
Using 7, 10, 11 and 16 month wet-plant cloning clonal afforestation, afforestation survival rate and 5-year survival rate and growth of the survey analysis showed that: survival and preservation rate of wet pine than wetlands But the growth was obviously greater than that of Pinus elliotis, which showed that the growth of Pinus tabulaeformis was obvious and had great popularization value. The afforestation effect of 4 wet seedlings of Pinus elliottii seedlings was 10, 11 and 16 months The survival rate, preservation rate and growth rate of wet-plus pine seedlings were significantly better than those of 7-month-old seedlings. Taking into account the cost of seedling and afforestation effect, it is considered that afforestation with 10 or 11-month seedling afforestation effect is good.
