Method for promoting culture of cyclobalanopsis glauca (Thunb.) Oerst. seedlings

Abstract

The invention discloses a method for promoting the culture of cyclobalanopsis glauca (Thunb.) Oerst. seedlings. Mixed medium of long lasting controlled release fertilizer is adopted, main roots and lateral root systems do not adopt air root cutting, the main roots and longer lateral root systems can pass through the bottom parts of a container and a seedling nursery plate to penetrate through thenursery ground for growth, well developed fibrous root systems are formed by manual cutting for many times, few lateral root systems can make series flow growth between containers, and the seedling success of the cyclobalanopsis glauca (Thunb.) Oerst. is greatly improved by the technical measures of seed wet sand stratification, disinfection, reasonable fertilizer, water, light irradiation, seedbed management and the like. The invention has the technical advantages of developed seedling fibrous root systems, prosperous growth vigor and convenient management, and has obvious difference from the conventional outdoor seedling culture and the like. The seedlings cultured by adopting the technology has high afforestation survival rate and transplanting survival rate and short transplant recovering period; and the invention effectively improves the quality of seedling afforestation and transplanting, has obvious benefits, and can be widely popularized and applied in production; and meanwhile the method also can be applied to the forcing culture of seedling of other tree species of fagaceae.

Description

technical field [0001] The invention relates to the technology of raising seedlings of woody plants, in particular to a method for promoting the cultivation of seedlings of P. Background technique [0002] The Fagaceae tree species are mostly evergreen or deciduous trees, and a few are shrubs. There are more than 900 species in 8 genera in the world, which are widely distributed in temperate, subtropical and tropical regions. In my country, there are 7 genera and more than 300 species, which are distributed several times throughout the country. Most species of Fagaceae play an important role in forestry production and are the main tree species in subtropical forests in my country. Its material is heavy and durable; the bark and funnel contain tannin, which can be used to extract gum; the fruit is rich in starch, which can also be used for wine making and industrial starch; Fagaceae species have well-developed taproot system, luxuriant branches and leaves, and have a good wat...

AI Technical Summary

Problems solved by technology

However, because the Fagaceae tree species are taproot tree species, the main root of the seedlings is well developed, and the lateral root system is few and weak. The seedlings cultivated by conventional open field sowing grow slowly, and the survival rate of transplanting and afforestation is extremely low, which seriously restricts the development and utilization of this family tree species.
