Cultivation and cultivation method of a crape myrtle landscape art tree that shrinks in three years and becomes a tube in five years

Abstract

The invention discloses breeding and cultivating methods for Lagerstroemia indica landscape trees capable of shrinking holes in three years and forming cylinders in five years. The breeding method comprises the steps of selecting single nursery-grown plants, carrying out composition shaping, carrying out burying, carrying out reshaping, carrying out pruning and carrying out sizing. Lagerstroemia indica bred according to the breeding method disclosed by the invention has the advantages of stable genetic characters and consistent growth nature, the growth process of the Lagerstroemia indica is the same as that of a nursery-grown plant, and the Lagerstroemia indica absorbs nutrients from underground like the nursery-grown plant, so that the vulnerable point that each single nursery-grown plant is low in shaping speed is overcome, the Lagerstroemia indica can meet indexes, and thus the Lagerstroemia indica can be planted as soon as possible and be applied to greening quickly. After the Lagerstroemia indica is subjected to transplanting by using the cultivating method disclosed by the invention, the Lagerstroemia indica can completely adapt to living environment for single plants, so that greening and beautifying of cities and towns are achieved. Furthermore, the Lagerstroemia indica grows into a relatively-thick tree, and then, the commodity value is relatively high, so that the economic benefit is increased.

Description

technical field

[0001] The invention relates to the technical field of landscape art trees, in particular to a method for cultivating and cultivating crape myrtle landscape art trees with shrinkage cavities in three years and five years in tubes. Background technique

[0002] The prospect of the International Federation of Architects for the new century is: to build the city in green. my country's ecological city construction is developing rapidly, and the current urban construction has reached the sixth stage, the main task of this stage is to develop green. While greening, we must also beautify the environment and create an ecological oasis. There are many tree species suitable for urban greening and beautification, but the number of them that meets the requirements of each city's natural environment is limited, especially large landscape art trees are in short supply. With the requirements of ecological security, it is impossible for big trees to enter the city. [000...
