容器育苗是一种新的育苗方式,在现代的林业发展中得到广泛的应用。通过利用容器育苗技术可以极大地节省种子的投资成本、育苗期也较短、成活率以及提高苗本生长速度和质量好等特点,同时,也方便于运输、延长造林时间等优势。因此。通过利用容器育苗技术可以很好地加快造林的进程,有效地实现林业的快速发展。阐述如何从这个角度进行林业育苗及苗期管理以保证育苗的成活率。
Container seedling breeding is a new way, in the modern development of forestry has been widely used. Through the use of container seedling technology can greatly save the cost of seed investment, seedling stage is also short, survival rate and improve the growth rate of the seedlings and good quality characteristics, but also facilitate the transport, extend the advantages of afforestation time. therefore. Through the use of container seedling technology can speed up the process of afforestation, effectively achieve the rapid development of forestry. Describe how forestry nursery and seedling management from this perspective to ensure the survival rate of nursery.
