[0024] A kind of cultivation method of Chinese tallow tree, the specific cultivation steps are as follows:

[0025] (1) Breeding: Take some seeds, soak them in tap water at 0-4°C for 16 hours, rinse with deionized water 4 times, add deionized water and potassium dihydrogen phosphate solution, shake well; put in a fume hood and add Sodium azide mutagenesis solution, this solution uses deionized water as solvent, mixes well, after standing for a period of time, take out the seeds and dry them with paper towels in a fume hood, plant them in 0.4% salt ponds, natural selection and Artificial selection, screening out salt-tolerant mutants, the selected salt-tolerant mutant materials are planted in rows in drought-salt seed selection gardens, screened and selected under salt adversity stress and propagate seeds;

[0026] (2) Seedling cultivation: through uniform irrigation and fertilization until the seeds grow naturally for 2 years;

[0027] (3) The first selection of seedlings: se...

Abstract

The invention relates to a cultivation method of cluster Chinese tallow trees, the cultivation method comprises the steps that a sodium azide mutagenesis solution is added into Chinese tallow tree seeds, then the seeds are planted in a salt pond, salt-tolerant mutants are screened out, irrigation and fertilization are conducted on seedlings in the mode of leaning one sides, and root systems of theseedlings are distributed in oval shapes with sparse ends and flourishing ends in soil balls; and a plurality of seedlings are circumferentially arranged in sequence and spliced and clustered again,large roots at the sparse ends of the soil balls are crossed and spliced, and then clustered Chinese tallow trees with good conditions are obtained through clustered shaping, supporting and fixing, pruning and shaping and regular maintenance. According to the cultivation method, sodium azide is selected as a salt-tolerant clustered Chinese tallow tree breeding mutagenic agent, damage to mutagenicseeds is small, salt-tolerant genes of Chinese tallow trees can be fully expressed, and drought resistance and dry hot air resistance can also be fully expressed; then irrigation and fertilization areconducted on the seedlings in the mode of leaning one sides, so that the sparse ends and the flourishing ends are generated at the roots of the Chinese tallow tree seedlings; and then, soil ball digging and cutting are carried out on the Chinese tallow tree seedlings, and splicing planting is carried out with dense seams, so that the spacing among the seedlings is effectively reduced, bending andcompressive death of the seedlings are avoided, and the ornamental effect of round crowns of the clustered Chinese tallow trees is guaranteed.

Description

technical field [0001] The invention relates to the technical field of plant cluster cultivation, in particular to a cultivation method of cluster Chinese tallow tree. Background technique [0002] Chinese tallow tree is a deciduous tree. Chinese tallow tree is a kind of tree species with colored leaves. It is a unique economic tree species in China with a cultivation history of more than 1400 years. Chinese tallow tree has strong adaptability to soil. It can be used in red soil, yellow soil, yellow-brown soil, purple soil, brown soil and other soils, soils with different textures from sand to clay, and acidic, neutral or slightly alkaline soils. It is one of the arbor species with strong salt resistance. [0003] The individual tallow tree is small. If it is planted in saline-alkali land, Northwest China with a lot of wind and sand, or used in urban landscapes, it needs to use clustered tallow tree. At present, the cultivation of clustered tallow tree is usually based on ...
