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.

Embodiment 1

[0039] Select one red Chinese tallow tree seedling, one purple Chinese tallow tree seedling, one yellow Chinese tallow tree seedling and one orange Chinese tallow tree seedling with a ground diameter of 2 cm for mosaic planting;

[0040] Spray auxin with a concentration of 100mg / L from May to July in the growing season, once a month;

[0041] In the dormant season of the first year of Chinese tallow tree seedlings, the stubble treatment is carried out; in May of the second growing season, the peripheral branches are thinned and pruned, and 5 evenly distributed first-level branches and 20 second-level branches are retained. The length of the branch is controlled at 20cm, the length of the secondary branch is controlled at 60cm, and the inner chamber branch is cleaned;

[0042] From May to July in the growing season, apply 1 kg of compound fertilizer containing phosphorus and potassium to each tallow tree seedling; from December to January in the dormant season, apply 5 kg of de...

Embodiment 2

[0044] Select 2 red Chinese tallow tree seedlings and 2 yellow Chinese tallow tree seedlings with a ground diameter of 2 cm for mosaic planting;

[0045] Spray auxin with a concentration of 500mg / L from June to July in the growing season, once a month;

[0046] In the dormant season of the first year of Chinese tallow tree seedlings, the stubble treatment is carried out; in May of the second growing season, the peripheral branches are thinned and pruned, and 8 evenly distributed first-level branches and 25 second-level branches are retained. The length of the branch is controlled at 40cm, the length of the secondary branch is controlled at 80cm, and the inner chamber branch is cleaned;

[0047] From June to July in the growing season, apply 2kg of compound fertilizer containing phosphorus and potassium to each tallow tree seedling; from December to January in the dormant season, apply 8kg of decomposed organic fertilizer.

Embodiment 3

[0049] Select 4 red tallow tree seedlings with a ground diameter of 2cm to carry out mosaic planting;

[0050] Spray auxin with a concentration of 1000mg / L once in June in the growing season;

[0051] In the dormant season of the first year of Chinese tallow tree seedlings, the stubble treatment was carried out; in May of the second growing season, the peripheral branches were thinned and pruned, and 10 evenly distributed first-level branches and 30 second-level branches were retained. The length of the branch is controlled at 60cm, the length of the secondary branch is controlled at 100cm, and the inner chamber branch is cleaned;

[0052] In June in the growing season, apply 3kg of compound fertilizer containing phosphorus and potassium to each tallow tree seedling; in December to January in the dormant season, apply 10kg of decomposed organic fertilizer.

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 ...
