试验采用春季黄连木播种塑膜容器育苗与秋冬季黄连木播种塑膜容器育苗的造林对比试验,为缩短黄连木育苗生产周期,提高黄连木育苗造林成效,加快黄连木生态能源林建设提供科学依据。试验结果表明,在3月采用黄连木种子直播13cm×20cm塑膜容器(配制营养基质)培育苗木135d后,于7月出圃,苗木个体差异不大,生产周期可缩短120d,造林成活率97.8%以上,逐年保存率达95.3%,不仅可有效节约育苗生产土地占用时间,降低生产成本,提高单位土地面积新增效益,且造林成效显著。
Experiments using Pistacia chinensis sowing plastic film container seedlings and the autumn and winter Pistacia sylvestris plastic film container seedling afforestation comparative trials to shorten the Pistacia chinense seedlings production cycle and improve the effectiveness of Pistacia chinensis nursery afforestation and accelerate the construction of Pistacia chinensis ecological energy forest provide a scientific basis . The test results showed that in March, seedlings of P. chinensis planted in 13cm × 20cm 13 cm × 20cm were incubated for 135 days in July. There was no significant difference in seedling production between July and April. The production cycle could be shortened by 120 days and the survival rate of afforestation was 97.8% , The annual preservation rate of 95.3%, not only can effectively save seedling production land occupation time, reduce production costs and increase the unit area of land new benefits, and afforestation achieved remarkable results.
