Method for cultivating clustered sapium sebiferum seedlings

Abstract

The invention discloses a method for cultivating clustered sapium sebiferum seedlings, which comprises the following steps of: selecting seedlings, namely selecting a plurality of sapium sebiferum seedlings with the same color system or different color systems to be planted together; auxin spraying, wherein auxin spraying is conducted in May to July in the growing season; trimming, namely performing stumping treatment in the dormant season of the first year of planting the sapium sebiferum seedlings; thinning and shearing the peripheral branches in May to July in the growing season of the second year so as to control the number and length of the first-stage branches and the second-stage branches, and meanwhile, cleaning the inner bore branches; water and fertilizer management: performing water and fertilizer management in a growing season and a dormant season respectively. According to the method, growth of nursery stock branches can be promoted by timely spraying auxin, and first-layer branches are cultured early; proper pruning is carried out by combining the pseudo-binary branch characteristic of the sapium sebiferum, so that a full crown shape can be quickly obtained; water andfertilizer management in the growing period is matched to promote seedling growth; sapium sebiferum seedlings of different color series varieties are selected for cultivation, and multi-color clustered sapium sebiferum seedlings can be obtained.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a method for cultivating clustered Chinese tallow tree seedlings. Background technique [0002] Chinese tallow tree is a tall deciduous tree with fast growth, long life, and few pests and diseases. It is not only resistant to drought and barrenness, but also resistant to water and humidity and mild to moderate salinity. In autumn, the color of the leaves is rich in variation, including red, yellow, purple and other colors. It is colorful, and the treetops are covered with white seeds in winter, like a little plum blossom, which lasts for a long time. It is an excellent ecological greening and garden landscape tree species. Clumping seedlings mean that the branching point of the tree is at the unearthed position or the branching point is lower. Compared with tall stem seedlings, clumping seedlings have the advantage of rapid formation and easy formation of a ...

Problems solved by technology

[0003] With the improvement of people's living standards, the aesthetic requirements for the surrounding environment are also gradually increasing, and the supply of garden trees with special ornamental value is in short supply. At present, the mainstream seedlings in the Chinese tallow tree market are still cultivated alone, and some clustered Chinese tallow tree seedlings are supplied, but most of them are Use low-quality Chinese tallow tree seedlings to simply piece together and cultivate, because they are all seedlings, without breeding, the color rendering effect in autumn is very unstable, and the overall color is not beautiful enough, it is difficult to meet the aesthetic needs of the public; The remaining low-quality seedlings in the nursery are patched together and bundled for natural planting. Without scientific pruning, germination promotion, and guided cultivation, it is difficult to form a perfect spherical crown, which seriously affects the application effect of gardens.
