Embodiment 1

[0025] (1) Establish a garden: select Xiashu loess with fertile soil, good drainage, and a pH value of 6.5, plow 30cm deep in autumn, plow 25cm shallowly in early spring, and apply base fertilizer, which is livestock manure such as cattle, pigs, sheep, chickens, etc. After half a year to one year of fermentation and maturity, mix with 1 times the garden soil, and the fertilization rate is 60000kg / ha 2 .

[0026] (2) Planting density: Before buds germinate in early spring, select 3-year-old Metasequoia cutting seedlings with strong seedlings and no pests and diseases, cut off old roots and sick and weak branches, and plant them at a row spacing of 4×4m; vertically plant on both sides of Metasequoia to grow robustly The cutting seedlings of Photinia fragrans of 3 years old are planted at a distance of 1m, and the distance between them and metasequoia is 1.5m, and the planting height is 1.2m.

[0027] (3) Plastic pruning: Leave 6-7 leaves for each new plant in late July of the y...

Embodiment 2

[0031] (1) Establish a garden: choose hilly Huanggang soil with flat terrain, loose soil, sufficient light, and a pH value of 6.3, plow 35 cm deep in autumn, plow 20 cm shallowly in early spring, and apply base fertilizer, where the base fertilizer is cattle, pigs, sheep, chickens and other livestock. The poultry manure is fermented and decomposed for half a year to one year, then mixed with 1 times the garden soil, and the fertilization rate is 75000kg / ha 2 .

[0032] (2) Density of colonization: Before the buds germinate in early spring, select the cutting seedlings of Metasequoia 4-year-old with strong seedlings and no pests and diseases, cut off the old roots and sick and weak branches, and plant them according to the row spacing of 3×5m. Cutting seedlings of 2-year-old Photinia fragrans, the distance between plants is 1m, and the distance between beech trees and zelkova is 1.8m, and the planting height is 1m, and the main trunk of the branches is topped; the flowers and l...

Embodiment 3

[0037] (1) Establish a garden: choose a garden with flat terrain, fertile soil, and good drainage, plow 30cm deep in autumn and winter, and plow 25cm shallowly in early spring, and apply base fertilizer, where the base fertilizer is cattle, pigs, sheep, chickens and other livestock and poultry manure after half a year After one year of fermentation and decomposing, mix with 1 times the garden soil, and the fertilization rate is 37500kg / ha 2 .

[0038] (2) Density of colonization: Before the buds germinate in early spring, select the cutting seedlings of metasequoia 4-year-old with no diseases and insect pests, cut off the old roots and weak branches, and plant them according to the row spacing of 4×5m. Cutting seedlings of 3-year-old Photinia fragrans, with a plant spacing of 1m, and a distance of 2m from the golden-leaf metasequoia, and a planting height of 1.4m, topping the trunk of the branches; planting Ophiopogon japonicus in the space between the two trees.

Abstract

The invention discloses a stereoscopic cultivation method of metasequoia glyptostroboides goldrush, photinia fraseri and ophiopogon japonicas and belongs to the field of seedling cultivation. The method mainly includes the following steps of garden plot building; field planting; pruning; field management and harvesting and garden delivery. The metasequoia glyptostroboides goldrush, photinia fraseri and ophiopogon japonicas with different ecological habits are selected for stereoscopic cultivation, the habits of the plants are complementary, the problem that the land utilization rate and economic benefits are low when the metasequoia glyptostroboides goldrush is planted singly is solved, forest weeds are reduced, and the method is convenient to operate, low in cost and easy to apply and popularize.

Description

technical field [0001] The invention relates to a seedling cultivation technology, in particular to a three-dimensional cultivation method of metasequoia aureus + Photinia fruticosa + Ophiopogon japonicus. Background technique [0002] Metasequoia (Metasequia glyptostroboides) is a special product in my country and a world-renowned rare relic species. It is a deciduous tree with a height of 40m. . Golden leaf metasequoia (Metasequia glyptostroboides'GoldRush') is an excellent color-leaved tree species selected from metasequoia. It not only has strong upright trunk, pagoda-shaped tree crown, fast growth, golden yellow leaves, but also is light-loving and cold-resistant. It is widely used in garden landscapes. The demand is high. Red leaf Photinia (Photinia×fraseri) is an evergreen shrub formed by crossing the parents of Photinia serrulata and Photinia glabra. Because of its bright red color of new leaves, it has the characteristics of beautiful posture, seasonal appearance a...
