Cuttage method for crape myrtle twigs with low cost and high survival rate

Abstract

The invention discloses a cuttage method for crape myrtle twigs with a low cost and a high survival rate, and belongs to the field of plantation. The method specifically comprises the steps of selection of cutting slips; preparation of treating fluid for roots; treatment of the cutting slips; preparation of cutting medium; cuttage of the cutting slips; management after the cuttage. According to the cuttage method, all the operational steps are reasonable in matching, and the survival rate of the cultivated cutting slips reaches 97% or above; due to the fact that the physical performance of the cutting slips is improved, the management cost is reduced in the cuttage process, the cost of the finally cultivated cutting seedlings is reduced by about 30% compared with a traditional method, and thus economic benefits are increased greatly.

Description

technical field [0001] The invention belongs to the field of planting, and in particular relates to a cutting method of crape myrtle twigs with low cost and high survival rate. Background technique [0002] Lagerstroemia indica, also known as hundred day red, full house red. It is a dicotyledonous plant of the genus Lagerstroemia in the genus Lagerstroemia. Native to southern Asia and northern Australia. It is distributed in East China, Central China, South China and Southwest China, and is widely cultivated in various places. The crape myrtle tree is beautiful, the trunk is smooth and clean, and the flowers are gorgeous; when it blooms, it is the season of few flowers in summer and autumn, and the flowering period is extremely long, from June to September, so it is called "hundred-day red" and "midsummer green cover eyes". , This bounty is full of praise" is a good bonsai material for viewing flowers, viewing stems, and viewing roots. It likes light, slightly shade-tole...

Problems solved by technology

[0003] Lagerstroemia crape myrtle can usually be propagated by sowing, cutting or branching. At present, seed propagation is the main method. However, this method of propagation is not good for seedling emergence, the damage to overwintering is large, and the traits are easily mutated; Pay attention to the shaping and pruning of crape myrtle

Cutting propagation is a convenient way to maintain the excellent traits of the female parent. Cuttings can be divided into tender branch cuttings and hard branch cuttings. The meristems of young branches are active and relatively easier to survive, but they are poor in weather resistance and require strict management. , hard branches are just the opposite. The existing cutting technology is not systematic for the cutting research of the above two methods, resulting in low rooting rate, easy to get sick, low seedling rate, complicated management, and high breeding costs.
