摘要
通过对丝绵木不同种子处理播种育苗和不同苗龄苗木无灌溉荒山造林试验,初步解决丝绵木在本地苗木生产和荒山造林适宜苗龄问题。试验表明,5年生生长健壮苗木可作为采种母树;室内沙藏应覆沙5 cm以上抑制种子过早发芽;秋季和春季均可进行播种育苗,去除假种皮可促进苗木破土;苗圃气候干旱,播种后要加强灌溉措施,否则导致育苗失败。1~5年生苗木均可用于荒山造林,考虑造林成本和其他因素,荒山造林建议使用2年生裸根苗;容器苗当年可直接用于造林。
Through the experiment of planting seedlings with different seed treatment and planting seedlings with different seedling ages in non-irrigated barren hills,the problem of suitable seedling ages of Euonymus bungeanus in local seedling production and barren hills was preliminarily solved.Experiments show that 5 years growth robust seedlings can be used as seed trees;Indoor sand storage should be covered with sand more than 5 cm to inhibit the early germination of seeds;Seeding can be carried out in autumn and spring,and removing the false seed cover can promote the breaking of the soil.Nursery climate is dry,after sowing to strengthen irrigation measures,otherwise lead to seedling failure.1~5 year’s old seedlings can be used for afforestation of barren mountains.Considering afforestation cost and other factors,it is recommended to use 2 years old bare root seedlings for afforestation of barren hills.Container seedlings can be directly used for afforestation.
