Large-scale cutting propagation method of ligustrum japonicum 'howardii'

Abstract

The invention discloses a large-scale cutting propagation method of ligustrum japonicum 'howardii'. The large-scale cutting propagation method includes: preparing a mist irrigation system, cultivating seedlings on trays, evenly mixing vermiculite, peat, perlite and river sand according to the proportion, by mass, of 5:3:1:1 to prepare a base material, sterilizing, adding slow-release fertilizer prior to mixing, cutting every branch section into a spike strip, keeping opposite leaves with halves reserved, reserving two lateral buds, emphasizing on management of shading and moisture preserving, and transplanting when cutting seedlings grow to 4-6cm. According to the large-scale cutting propagation method, the seedlings are cultivated on the trays, the base material of the trays is prepared with high moisture content, no sterilization residue exists, management is needless for a long time due to the addition of the slow-release fertilizer, and the problems that conventional fertilizer application is uneven and large-scale propagated cutting seedlings are hard to manage are solved. The opposite leaves are half cut and the 2 lateral buds are reserved, so that sprout tillering of branches is improved, and branch shapes of the grown ligustrum japonicum 'howardii' are nice-looking.

Description

technical field [0001] The invention relates to the field of seedling propagation, in particular to a method for large-scale cutting propagation of Ligustrum jinsen. Background technique [0002] Jinsen Ligustrum is an evergreen shrub or small tree of the genus Ligustrum in Oleaceae, with opposite phyllotaxy. Jinsen Ligustrum grows vigorously, has strong germination ability, high resistance to diseases and insect pests, thick leaves, and good texture. In horticultural applications, Jinsen Ligustrum The color of privet is bright, and the leaves are golden in winter and spring. It is very beautiful to match with other colored preparations. Since Ligustrum jinsen is a variety imported from Japan, the cultivation and production in my country is still in the stage of exploration and research, and the large-scale planting of privet jinsen is not effective. [0003] The traditional cuttings of Jinsen Ligustrum are pruned with one leaf and one bud, and they are bred at a suitable t...

Problems solved by technology

Since Jinsen Ligustrum is a variety imported from Japan, the cultivation and production in my country is still in the stage of exploration and research, and the large-scale planting of Jinsen Ligustrum is not effective.

[0003] The traditional cuttings of Jinsen Ligustrum are pruned with one leaf and one bud, and they are bred at a suitable temperature with high humidity. However, under large-scale production, the seedlings are closely arranged, and the initial fertilization may be uneven. In order to ensure that the cuttings do not lose water, they are covered with film. , which leads to the inability to carry out effective management, and the traditional cutting method produces Jinsen Ligustrum, which has a high trunk, slow growth of lower branches, and unsightly branch shape, which reduces the performance of the product.
