Description
Technical Field
The invention relates to the field of flower and leaf (leaf-changing) planting, in particular to a cutting method of flowering leaf (leaf-changing) begonia.
Background
Malus spectabilis (academic name:Malus transitoria(batilin) c.k. Schneid.) is a shrub to small tree, up to 8 meters in height; the small branches are slender and cylindrical. Oval to broad oval shape of leaves, usually 3-5 irregular deep fissures, long oval to oblong shape of lobe, lobar matter, ovoid-like needles-like shape, full margin. The inflorescence is nearly umbrella-shaped, and has 3-6 flowers, bract membranous substance, linear shape coated with needles, sepal bell shape, sepal triangular egg shape, petal egg shape, pink color and white color; 20-25 parts of stamens. The fruit is nearly spherical. The flowering period is 5 months, and the fruit period is 9 months. Elevation 1500-3900 meters in jungles on mountain slopes or on loess hills. Distributed in Mongolia, Gansu, Qinghai, Shaanxi and Sichuan.
Malus toringoides (academic name:Malusthe twingudes is of the genus Malus of Rosaceae (Rosaceae) ((R))Malus) The plant of (2) is a specific plant of China. Rehd described him as a variant of malus spectabilis in 1915, followed by the american botanist Hughes, standing as an independent species. The malus toringoides has rich diversity in the aspects of living environment adaptation, morphological characteristics and stress resistance. It is mainly distributed in Gansu, Tibet, Sichuan and other places in continental China, grows in areas with elevation of 2,000-3,000 meters, mostly grows in hillside jungles, and is introduced and cultivated manually at present.
Cutting propagation refers to a propagation method of using the habit that plant vegetative organs have regeneration capacity and can generate adventitious buds or adventitious roots, cutting a part of stems, leaves and roots of the plant vegetative organs, and inserting the cut part into soil or other matrixes to enable the roots or buds to become new plants. The plant used as the cutting parent needs to have the conditions of good variety, vigorous growth, no pest damage and the like, and the aged plant is not selected as the cutting parent. On the same plant, the middle-upper part of the cutting is selected to be branches which are sunny and full, the internodes are short, the bud heads are full, and the branches and leaves are thick. On the same branch, the middle lower part of the branch is selected for hard branch cutting because the middle lower part stores more nutrients and the tip tissue is often not full, but the coniferous trees with regular tree shapes, such as dragon juniper, cedar and the like, take the tip with a top bud as the best, the later grown cutting trunk is straight, the shape is beautiful, the butted cutting is carried out, the top which is too tender is cut off, and chrysanthemum and the like are just tender heads when in cutting.
The cuttage advantage: (1) the excellent genetic characters of the parents can be well preserved through cutting propagation, and character separation generated by sowing propagation is avoided. And aiming at finding out valuable bud mutation, excellent lines can be cultivated through cuttage. (2) The cutting propagation can cultivate seedling in a short time and can also cultivate seedlings with certain specifications in a planned period according to the size of the cutting.
The defects of cuttage are as follows: (1) the cuttage rooting rate is low. (2) The cutting seedlings have no main root, and the root system is weaker than that of the seeding seedlings, and is usually shallow root. (3) The cuttage is easy to invade by germs in soil or matrix, and the survival rate is low.
Disclosure of Invention

In summary, due to the adoption of the technical scheme, the invention has the beneficial effects that:
1. the film-forming agent enables the cuttage agent to form a film layer with air permeability on the surface of the cut, so that the cutting slips can be separated from a matrix, invasion of germs can be effectively prevented, and meanwhile, water loss can be prevented; the cuttage rooting requires certain humidity, and the humectant in the cuttage agent can keep the humidity of the wound surface, so that the rooting rate of the cutting slips can be effectively improved.
2. The rooting powder can promote the rooting rate of the cuttings, and the bacteriostatic agent can further prevent the invasion of germs and improve the rooting rate.
3. The invention is suitable for different cutting modes, and meanwhile, as the film is formed on the surface of the wound, the management of the cutting slips can be convenient, the cutting slips can be directly hung on the bracket without being inserted into soil or water, the use space is reduced, and the convenience of cutting is improved.
