苗木类型对油茶造林效果的影响

Effect of different seedlings types on afforestation of Camellia oleifera

针对油茶造林成活率不高的问题,调查了不同油茶苗木类型对造林效果的影响。结果表明:容器苗的造林成活率及造林后幼林长势明显优于裸根苗,以无纺布轻基质苗最好,造林成活率达90.6%。苗龄对容器苗造林成活率有较大影响,其中以3年生容器杯大苗的造林成活率最高,造林成活率达98.3%。容器杯实生苗的造林成活率及造林后幼林前期生长要优于容器杯嫁接苗,但花芽出现的时间较容器杯嫁接苗要晚。

Aiming at the low survival rate of afforestation of Camellia oleifera,the effect of different seedlings types on afforestation were investigated.The results showed that,the survival rate of afforestation of the container seedlings and its growth after afforestation were obviously better than those of bare-root seedlings,and the light matrix seedling had the highest survival rate of afforestation,which reached 90.6%.The survival rate of afforestation of container seedling was greatly affected by seedling age,and the big container seedling with three-year-old had the highest survival rate of afforestation,which reached 98.3%.The survival rate of afforestation and early growth of container family seedlings were superior to those of container grafting seedlings,but the flower bud appeared later.
