Problems solved by technology

The cultivation cycle of this method is long, the process is complicated, the cutting seedlings are easy to rot, and the survival rate is low; the second is to use the semi-lignified new shoot cuttings in summer, this method needs the help of corresponding agricultural facilities and electronic spraying facilities Cutting propagation can be completed, cutting seedlings are prone to lack of water due to poor management, and the survival rate is not high
[0004] It can be seen that the existing crape myrtle cutting propagation technology has complex cultivation methods, many equipment needed for management, low survival rate, and slow cultivation speed.

Abstract

The invention relates to a lagerstroemia indica cutting breeding method, which belongs to the technical field of plant cuttage. The method comprises the following steps: I, preparing a cutting matrix, sterilizing perlite, coco coir, peat and red earth, uniformly mixing with growth liquid, and spraying chitosan gel; II, cutting: selecting epicormic branches of the lagerstroemia indica for cutting; III, cutting managing: managing the sunlight, temperature, humidity, nutrition and sterilization; IV, transplanting to a plant nursery: transplanting the lagerstroemia indica to the plant nursery after the roots of the cut epicormic branches of the lagerstroemia indica are fully developed. The lagerstroemia indica cutting breeding method has the advantages of high survival rate and high growth speed.

Description

technical field [0001] The invention relates to a method for raising seedlings, in particular to a method for cultivating crape myrtle cuttings. Background technique [0002] Lagerstroemia crape myrtle is a plant of the genus Lagerstroemia genus in the genus Lagerstroemia. It is distributed in South China and Central my country, and is a commonly cultivated ornamental plant. In hot summer, when the group of flowers converges, only Lagerstroemia inflorescence blooms, and the flowering period is as long as 120 days. It is the most commonly used tree species in landscaping and has high cultivation value. [0003] There are two main methods for the current cutting propagation of Lagerstroemia crape myrtle: one is to collect annual branches before the branches sprout in spring, and insert them into loose, well-drained sandy loam seedbeds. The cultivation cycle of this method is long, the process is complicated, the cutting seedlings are easy to rot, and the survival rate is low;...
