Description

A kind of cultivation method of dwarf liquidambar bonsai

technical field

The invention relates to the technical field of planting garden trees, in particular to a cultivation method of dwarf liquidambar bonsai.

Background technique

Liquidambar tree, deciduous tree, up to 30 meters, diameter at breast height up to 1 meter, bark taupe. It likes warm and humid climate, sexually likes light, and is resistant to drought and barrenness. It is produced in the provinces south of the Qinling Mountains and the Huaihe River in China, and is also found in northern Vietnam, Laos and southern Korea. It likes warm and humid climate, sex likes light, young trees are slightly shade tolerant, resistant to drought and poor soil, and not waterlogging. It mostly grows in flatlands, near villages, and secondary forests in low mountains. It grows well on moist, fertile and deep red-yellow loam soil. Deep-rooted, thick and long taproot, strong wind resistance, not resistant to transplanting and pruning. The seeds have the habit of germinating every other year, are not cold-resistant, and cannot survive the winter in the open in the north of the Yellow River, and are not tolerant to salinity and drought. In Hainan Island, it often forms the dominant species of secondary forest. It is resistant to fire and has strong germination ability.

Due to its unique ornamental value, people are often not satisfied with viewing the garden, and want to put it in the office or in their own yard for viewing. Therefore, the cultivation of dwarf sweetgum bonsai is gradually favored by people. At present, other maple varieties such as triangular maple, red maple, etc. are used as bonsai for viewing and viewing, but liquidambar bonsai often brings problems to people because of its low survival rate and difficult control of plant type. Therefore, need a kind of new cultivation technology scheme to solve the above problems.

Contents of the invention

The object of the present invention is to provide a cultivation method of dwarf liquidambar bonsai, the cultivated liquidambar bonsai has distinct layers, well-proportioned layout, beautiful tree posture, good ornamental value, and high survival rate of liquidambar bonsai.

To achieve the above object, the present invention is achieved through the following technical solutions:

A kind of cultivation method of dwarf liquidambar bonsai, comprises the following steps:

(1) Select seedlings: select healthy and disease-free sweetgum seedlings, with a tree height of 25 to 45 cm;

(2) Making bonsai cultivation soil: There is a through hole at the bottom of the selected pot container, first lay a layer of pebbles on the bottom of the pot container, then lay a layer of river sand on the pebbles, and lay a layer of decomposed pebbles on the river sand. A layer of mixed soil containing paddy field soil, straw biomass carbon, fermented and decomposed mushroom slag organic fertilizer, chlormequat/attapulgite mixture, and 0.2% ferrous sulfate liquid is laid on the decomposed bean cake, and then mixed with Lay a layer of humus on the soil;

(3) Upper pot treatment: plant liquidambar seedlings in bonsai cultivation soil, the planting time is 2-3 months, pruning the branches and roots of transplanted seedlings before planting, and watering to the humus layer after planting wet;

(4) Dwarfing plastic pruning: Cut off the branches and buds that are not required in appearance in time, thin out old branches and dead stems at any time, and keep the bottom short; when the branches grow more than 10 cm, use 1400-2000 mg Paclobutrazol per kilogram is sprayed;

(5) Fertilizer and water management:

Watering: During the growing season, water frequently; when the weather is hot, sprinkle water on the ground to keep the air moist; enter a dormant climate, water less, and keep the pot soil moist;

Fertilization: When sweetgum is spreading leaves in spring, apply a decomposed and thin organic liquid fertilizer once, and apply a decomposed and thin organic liquid fertilizer once in August to September, and do not apply fertilizer during the winter dormant period.

Preferably, in the step (2), the cobblestone, river sand, decomposed bean cake, mixed soil and humus soil are all disinfected before use.

Preferably, in the step (2), the pot container is a white marble pot or a marble pot.

Preferably, in the step (2), the thickness ratio of the cobblestone layer, river sand layer, bean cake layer, mixed soil layer, and humus layer is 1:0.5～1:0.2～0.5:3～8:0.3 ~1.

Preferably, in the step (2), the preparation method of the chlormequat/attapulgite mixture is as follows: dissolve 1 part of chlormequat in 100 parts of water, spray it into 800-1200 parts of attapulgite, and stir it evenly Serve dry.

Preferably, in the step (2), the mass ratio of paddy field soil, straw biomass carbon, fermented and decomposed mushroom dregs organic fertilizer, chlormequat/attapulgite mixture, and 0.2% ferrous sulfate solution is 1:0.1 ~0.3: 0.1~0.3: 0.05~0.15: 0.005~0.01.

Preferably, in the step (4), when the branches grow more than 10 centimeters, 1600 mg/kg of paclobutrazol is selected for spraying.

The beneficial effect of the present invention is: the cultivation method of dwarf liquidambar bonsai of the present invention, the cobblestone layer and the river sand layer are laid once at the bottom of the pot container, can keep the air permeability of the soil, and the decomposed bean cake layer on the river sand layer can To provide continuous nutrient supply for red maple, the mix of various substances in the mixed soil is reasonable, the nutrients are balanced, the pH of the soil is suitable, suitable for the growth of sweetgum trees, and the survival rate of sweetgum trees is significantly improved. The mixture slowly releases chlormequat during the growth of the red maple, which can inhibit the growth of the sweetgum tree, inhibit the vigorous growth of branches and leaves, and dwarf the tree shape. After appropriate dwarfing pruning and fertilizer and water management in the later stage, the appearance of the liquidambar tree can be effectively controlled, so that the liquidambar bonsai has distinct layers, well-arranged layout, beautiful tree posture, and has good ornamental value.
