试验采用黄连木塑膜容器培育135d苗木与1年生大田裸根苗的造林对比试验,为缩短黄连木育苗生产周期,降低生产成本,提高造林成效,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月出圃造林技术,较培育1年生大田裸根苗生产周期缩短了225d,降低造林成本25.26%,造林成活率97.8%以上,逐年保存率达95.3%。具有生产成本低,育苗占地时间短,造林成效显著特点,还可进一步提高单位土地新增效益。
In this experiment, the experiment of afforestation comparing the 135 days nursery stock with the one-year nursery root nursery stock was conducted in this experiment. This study provides a scientific basis for shortening the production cycle of P. nucifera nursery stock, reducing the production cost, improving the afforestation effectiveness and accelerating the ecological energy forest construction. The results showed that in March, planting seedlings of P. chinensis seedlings in 13 cm × 20 cm were filled by 135 cm plastic seedlings (nutrient matrix), and the afforestation technology in July was shorter than that of one-year bare nursery for 225 days in afforestation The cost of 25.26%, afforestation survival rate of 97.8% or more, the annual saving rate of 95.3%. With low production costs, seedling covers a short time, afforestation remarkable characteristics, but also to further improve the unit of land new benefits.
