Method for cutting orchard construction and cuttage of Castanopsis hystrix

Abstract

The invention belongs to the technical fields of cutting orchards and cuttage of Castanopsis hystrix, and discloses a method for cutting orchard construction and cuttage of the Castanopsis hystrix. The method adopts a series of cutting orchard construction and cuttage breeding technologies like nursery land selection and soil preparation, stock plant height control in a cutting orchard, nutrient control and cutting scion selection, seedbed substrate requirements, cuttage treatment and cuttage management. The method provided by the invention solves current situations like large variation of Castanopsis hystrix seeds and seedlings, unstable sources and uneven quality of seeds, large differentiation and low yield of afforestation stands and difficulty in meeting the demands of production forhigh-quality seedlings of an improved Castanopsis hystrix variety, basically achieves the technical level of rapid breeding of the improved Castanopsis hystrix variety, has significant economic benefits, provides an effective way for asexual breeding of the improved Castanopsis hystrix variety, breaks through a plurality of disadvantages caused by pure dependence on seed sowing for seedling raising of the Castanopsis hystrix for a long time, forms simultaneous development of sexual and asexual breeding from improved variety breeding of the Castanopsis hystrix, and exerts good promotion and acceleration effects on research and development of selective breeding and breeding of the improved Castanopsis hystrix variety.

Description

technical field [0001] The invention belongs to the technical field of red cone picking garden and cuttings, and in particular relates to a construction and cutting method of red cone picking garden. Background technique [0002] Castanopsis hystrix Miq. is an evergreen tree belonging to the family Fagaceae. It is an important and precious native broad-leaved timber tree species in southern my country. It has strong adaptability, fast growth and excellent material quality. One of the preferred afforestation tree species for construction. However, there are long-term differences in good and bad seedlings, unstable sources of seedlings, and large differentiation of afforestation stands, which restricts the improvement of red cone planting benefits. Therefore, through the research and development of improved seed selection and breeding technology, the construction of ear picking nurseries, and the propagation of superior seedlings of clones through cuttings are the primary task...

AI Technical Summary

Problems solved by technology

However, the existing red cone cuttings have low efficiency and low cutting survival rate.

Existing red cones seldom have regular construction ear picking gardens, basically all are to gather the fringes of saplings (2-4 year-old trees, with few side branches, and the height of the tree is about 2-5 meters, and it is difficult to take the branches on the top periphery of the tree canopy. Large) to cuttage, the number of effective branches is difficult to source, the survival rate of cuttings is low, the number of seedlings is small, the position effect of cutting seedlings is obvious, and the economic benefit is poor

[0004] In summary, the existing problems in the prior art are: the basic source of cuttings for cuttings is saplings, which have few effective cuttings, are difficult to collect, and are difficult to take root without larvae. supply

Solve the current situation of large variation of red cone seed seedlings, unstable seed sources and uneven quality, large differentiation and low yield of afforestation stands, and difficulty in meeting the demand for good seedlings of red cone seeds in production.

[0005] In summary, the problems in the prior art are: the existing red cone cuttings have low efficiency and low survival rate of cuttings

However, at present, the cuttings of red cones are seldom using the spikes in the ear-picking nursery, and the second is that the cutting technology in the existing literature has low practicability and low cutting rooting rate, which cannot meet the requirements of the asexual rapid propagation technology in the actual sense.
