Straight bar type individual plant cultivation method for lagerstroemia plant of lythraceae

Abstract

The invention belongs to the technical field of plant cultivation and relates to a straight bar type individual plant cultivation method for a lagerstroemia plant of lythraceae. The method comprises the following steps: 1, adopting a cutting propagation seedling culture method to culture seedlings; 2, mounting a stem cultivating and modeling formwork; 3, conducting fertilization and soil preparation; 4, planting nursery stocks; 5, cultivating stems; 6, managing and protecting the nursery stocks; 7, conducting seedling root diminution. According to the straight bar type individual plant cultivation method for the lagerstroemia plant of the lythraceae, lagerstroemia indica seedlings are cultured to individual plant nursery stocks to achieve cultivation of 2-5m and even higher straight bar type individual plant nursery stocks, a basic material is provided for cultivating large single-stem lagerstroemia indica wood and culture of different combination modeling by implementing multi-stem inarching culture, multi-stem inarching heating growth can be fast achieved to form a large tree, combined modeling of multiple forms can be conducted, commercial value and the enjoy effect of the nursery stocks are remarkably improved.

Description

technical field [0001] The invention relates to a method for cultivating a straight rod-type single plant of Lagerstroemia genus Lagerstroemia, belonging to the technical field of plant cultivation. Background technique [0002] For the production and standards of crape myrtle seedlings, see: "Landscape Seedling Production and Standards", edited by Shen Lianmin and Chen Xiangqiang, Zhejiang Science and Technology Press, October 2005, first edition, pages 105-106. This document discloses the production and standards of crape myrtle seedlings: (1) Seedlings are propagated by sowing, cuttings, and tillers; (2) Tree shape: single-stemmed seedlings: upright and obvious trunks, evenly branched; clustered seedlings: ornamental varieties and potted plants, It is often cultivated into clusters by manual pruning and fixed stems. Disadvantages: The single stem seedlings are generally upright trunks below 1-1.5 meters. The above-mentioned branches are selected and the height and direc...

AI Technical Summary

Problems solved by technology

Disadvantages: The single stem seedlings are generally upright trunks below 1-1.5 meters. The above-mentioned branches are selected and the height and direction of the branches are reasonably controlled. Due to the limited height, the cultivation method cannot meet the requirements of a single plant for the shape of a straight trunk of crape myrtle. production and requirements

Defects: Although the trunk of the seedlings can be well-proportioned and relatively soft, the seedlings can be used for modeling after the height of the seedlings reaches 150-200 cm and the dry diameter reaches 0.6-1.2 cm. -500 cm, because of high density, it is easy to cause lodging and change the dry type, it is difficult to control diseases and insect pests, resulting in loss of seedlings, and the root growth of individual seedlings is weak, which is not conducive to transplanting and survival. production and requirements
