Embodiment

[0032] A method of early dwarfing of the green money willow seed garden, as shown in the scene photos Figure 1-Figure 4 , which mainly includes the following steps:

[0033] 1. Selection of grafted mother trees and collection of spikes

[0034] The natural distribution area of Qingqian willow was inspected, and the adult tree with straight trunk was selected as the grafted and ear-picking mother tree (of which the fruiting amount of the excellent tree was used as the mother and the unsound youshu was used as the father), and the annual young branches without disease and insect pests were taken before the germination of the new shoots from February to March, wrapped with a wet towel and placed in ice packs to bring back to the nursery, placed in a 4 °C refrigerator, and waited for grafting. In the process of collecting, transporting and grafting the spikes, do a good job of moisturizing and cooling, and try to shorten the storage time of the scion.

[0035] It is necessary to do a ...

Abstract

The invention discloses a method for constructing an early-fruiting dwarf cyclocarya paliurus seed orchard. The method comprises the following steps: firstly, collecting current-year twigs of superior adult cyclocarya paliurus trees or ancient trees with solid main branches and side branches as scions; 1-3-year-old cyclocarya paliurus non-woven fabric container seedlings are selected as stocks to be grafted, and grafted seedlings are obtained; then selecting 1-2-year-old cyclocarya paliurus grafted seedlings for clone configuration planting; after the vigorous growth period of the cyclocarya paliurus is finished, top tips, vigorous branches and upper alternate side branches of the cyclocarya paliurus are trimmed, and fertilization management is conducted. According to the method, current-year twigs of superior trees are collected as scions for grafting, the obtained grafted seedlings are used for building the seed orchard, the early-fruiting dwarf cyclocarya paliurus seed orchard is obtained through tree body management, the requirement for use of good seeds in daily production is met, the problem that good germplasm resources of cyclocarya paliurus are deficient is solved, the cyclocarya paliurus seedling breeding and industrialization process is accelerated, and the economic benefit is increased. The method is of great significance to protection of endangered species and wood strategic reserve.

Description

Technical field [0001] The present invention belongs to the field of forestry technology, in particular to a method of construction of a green money willow seed garden. Background [0002] Cypriacaryapaliurus is a plant of the walnut family Cypria spp., a single species of plant unique to China, an important precious native tree species in our province, and one of the endangered plants under key protection. Qingqianliu integrates medicinal, material, health care and ornamental in one, because of its good effect on the prevention and treatment of cardiovascular diseases and diabetes, it is known as the "third tree" in the medical field, with high protection and development value. At present, most of the green money willow trees grow in the deep mountains and old forests, the tree shape is tall, the tree is as high as 20 meters, it is difficult to collect seeds, and the seeds of green money willow have deep dormant characteristics, and it takes every other year to germinate after ...
