Embodiment 1

[0018] (1) Seed collection: In the first ten days of October, choose a healthy 20-year-old tree with a strong and strong mother plant, and it is mature when the shell is dark brown. Store in sand at 0-5°C for later use;

[0019] (2) Seed pretreatment: 3 days before sowing, prepare a mixture of concentrated sulfuric acid and water with a volume ratio of 1:3. When the temperature of the mixture drops to 45°C, place the seeds of Castanopsis chinensis in the mixture. Stir clockwise at a speed of 30 min, soak for 2 hours, take out and air-dry, the treatment of concentrated sulfuric acid can effectively improve the germination rate of seeds;

[0020] (3) Sowing and raising seedlings: in early spring, choose sandy loam soil that is sheltered from the wind, has light, and is relatively humid, plows 25cm deep, sprinkles 20kg of calcium phosphate evenly per mu, applies 40kg of farmyard manure, and covers the soil; Sow 20 grains in 1m sowing ditch, the seeding rate is 60kg / mu, and cover...

Embodiment 2

[0025] (1) Seed collection: In late October, choose 30-year-old healthy, strong and strong mother plants of Castanopsis chinensis. When the shell is tea-brown, it is mature. Select nuts with large and full grains, bright seed shells, and no pests and diseases as seeds. Store in sand at 0-5°C for later use;

[0026] (2) Seed pretreatment: 5 days before sowing, prepare a mixture of concentrated sulfuric acid and water with a volume ratio of 1:5. When the temperature of the mixture drops to 60°C, place the seeds of C. Stir clockwise at a speed of 20 min, soak for 4 hours, take it out and air-dry, the treatment of concentrated sulfuric acid can effectively improve the germination rate of seeds;

[0027] (3) Sowing and raising seedlings: In early spring, choose sandy loam soil that is sheltered from the wind, has light, and is relatively humid, plows 40cm deep, sprinkles 30kg of calcium phosphate evenly per mu, applies 60kg of farmyard manure, and covers the soil; Sow 30 grains in...

Abstract

The invention discloses a seedling growing and forest planting method for castanopsis sclerophylla trees, and provides a whole set of seedling growing and forest planting method for the castanopsis sclerophylla trees in detail, wherein the seedling growing and forest planting method comprises the following steps of seed collecting, pretreatment of seeds, sowing and seedling raising, transplanting, forest planting, and soil, nutrient and water management in a later period. The seedling growing and forest planting method for the castanopsis sclerophylla trees effectively improves the germination rate of castanopsis sclerophylla seeds; a sowing and seedling raising method ensures the growth quality of plantlets; a reasonable transplanting method, a plantation density design and the soil, nutrient and water management at different stages in the later period also improve the transplanting survival rate of the castanopsis sclerophylla trees and increase the speed of forest establishment; grown trees have dense branches and leaves, perfectly round, tall and big crowns, high resistance to diseases, and high ornamental value; therefore, the seedling growing and forest planting method for the castanopsis sclerophylla trees plays a powerful role in boosting utilization and popularization of good varieties of trees in urban gardens and forestry ecological construction.

Description

technical field [0001] The invention relates to arboriculture technology, in particular to a method for growing seedlings and afforestation of Chinese oak trees. Background technique [0002] Castanopsis is an evergreen tall tree of the Fagaceae Castanopsis genus. It is naturally distributed in deciduous and broad-leaved mixed forests in the north subtropical, mid-subtropical and southern subtropical regions south of the Yangtze River. It has strong cold resistance, evergreen in four seasons, and dense branches and leaves. The crown is round and tall, quite beautiful, suitable for planting in patches on slopes, and is an excellent landscape tree species for landscape forests based on evergreen broad-leaved trees or as background trees for flowering shrubs. Due to its own characteristics, Castanopsis is a very good fire-resistant tree species, with high ignition point and strong germination ability. It can be used to build fire-resistant forest belts and create fire-resistant...
