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 the nursery 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 a seedling-raising technology for woody plants, in particular to a method for promoting the cultivation of C. chinensis seedlings. Background technique [0002] Fagaceae Fagaceae are mostly evergreen or deciduous trees, and a few are shrubs. There are 8 genera and more than 900 species 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 species of subtropical forests in my country. Its material is strong and durable; the bark and bucket contain tannins, which can be extracted and glued; the fruit is rich in starch, and can be used for winemaking and industrial starch; Fagaceae species have developed taproots, lush branches and leaves, and have good water conservation It is a veritabl...

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.
