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

Embodiment 1

[0056] Experimental situation of red cone cutting

[0057] In the spring (March 12) and autumn (October 28) of 2013, at the Fujian Provincial Forestry Science and Technology Experimental Center, the super seedling spikes bred in 2012 were used to try cuttings, cutting 320 plants; on October 10, 2015 in Xianyou Seedling breeding point of Xikou Forest Farm - Xianyou County Manguang Flower and Tree Nursery Professional Cooperative has carried out cutting experiments again, cutting 200 plants, and the spikes come from 3-year-old red cone plants in Hua'an, Pingxiang, Guangxi, and Anxi.

[0058] 1. The purpose of the cutting experiment: to try the feasibility of cutting, and lay the foundation for the next step of systematic cutting and propagation.

[0059] 2. Cutting time: 2013.3.12 and 2013.10.28 in the test center; 2015.10.10 in the Xianyou breeding base

[0060] 3. Source of cuttings: The cuttings of the experimental center come from semi-lignified cuttings of 1-1.5a super see...

Embodiment 2

[0071] Example 2: Experimental situation of controlling different heights of the mother plant in the red cone picking nursery

[0072] At the beginning of April 2016, at the Manguang Flower and Tree Nursery Professional Cooperative in Xianyou County, Fujian Province, it was bred with the seeds of excellent trees (20a) collected from the excellent provenance areas of Fujian Huaan, Anxi, Nanjing, Pingxiang, and Bobai in Guangxi. The 1-year-old super seedlings are used for the construction of ear gardens. In the process of implementation, different mother plant height control experiments were carried out. The survey measured the yield of spikes in the same year. The results showed that the height of the mother plant was controlled at 40cm to produce the most effective spikes (semi-lignified and with a bud eye). Take more than 20 effective spikes. And mother plant height is only 8-12 effective spikes of 20cm and 60cm.

[0073] Purpose of the experiment: to explore the best contr...

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...
