Container nursery method
The cultivation of seedlings in containers filled with nutrient soil is called container seedlings, and it is suitable for bare-rooted seedlings in areas and tree species that are not easy to survive; it is also suitable for the cultivation of rare tree species. Seedlings grown in this way are called container seedlings. Afforestation with container seedlings is an important means to improve the quality of afforestation. It is a pity that Zhejiang Province ranks second in the number of cases in this country, second only to Tibet, and it is not in line with the status of economic development. Therefore, it is necessary to strengthen the work in this area. Container seedlings have the following advantages: 1. Not subject to the limitation of the planting season: The container seedlings can be planted in all four seasons, which facilitates the rational arrangement of labor and can be planted in stages. 2. Saving seeds: 2~3 seeds are sowed per seed, the utilization rate of seeds is quite high, and 2/3~3/4 seeds are often saved than nursery seedlings. 3, can shorten the nursery life, is conducive to the realization of mechanization of nursery: General seedling nursery takes 8 to 12 months to plant out of the nursery, but the use of container nursery, only 3 to 4 months or less time can be out of the garden. When container seedlings are moved out of the nursery, the functions of lifting seedlings, planting and the like are omitted. The entire process of nursery can be implemented mechanical operation. It has created conditions for planting seedlings. Great savings in time, land and labor. 4, is conducive to the cultivation of high-quality seedlings: container seedlings can be sowed in advance to extend the growth period of seedlings, combined with easy management, can meet the humidity, temperature and light requirements of seedlings, and promote the rapid growth of seedlings, is conducive to the cultivation of strong seedlings. 5, can improve the survival rate of planting: container planting is the whole root whole seedlings, the roots are not damaged, can greatly improve the survival rate of planting. 6, is conducive to play in advance benefits: nutrient soil used in container seedlings high fertility, is conducive to the growth of seedlings; root development is good, strong resistance to adverse environmental ability, post-planting seedling period is short, or even slow seedlings, is conducive to early play afforestation benefits. Of course, container seedlings also have their shortcomings, mainly due to the low yield per unit area, complicated nursery techniques, and higher nursery costs than bare-rooted seedlings.
