Efficient magnolia grandiflora culture method

Abstract

The invention discloses an efficient magnolia grandiflora culture method. According to the method, the close planting enhancement is carried out during the seedling culture, when seedlings grow to a state that the trunk diameter is greater than 5cm, the local seedlings are subjected to additional fertilization, short cutting measures are taken for seedlings which are not subjected to additional fertilization, after the trunk diameter of the seedlings subjected to the additional fertilization reaches 10 to 12cm, the seedlings subjected to the additional fertilization are transplanted and are supplied to the market, and the rest seedlings are subjected to additional fertilization. The efficient magnolia grandiflora culture method provided by the invention solves the problems of slow benefit obtaining and low integral benefits in the traditional magnolia grandiflora culture technology. The cultured seedlings are sturdy, the crown shape and the trunk shape are very good, the pest and disease damage is little, the seedling root system is well developed, the seedling yield is high, the transplanting survival rate of greening seedlings is high, and the adaptability is high. The magnolia grandiflora culture mode has the advantages that on the basis of sufficiently utilizing the photosynthesis theoretical knowledge of trees and the forest ecological structure theory, the seedlings are creatively configured, various culture measures are flexibly utilized, the operation is simple, convenient and feasible, in addition, the cost is low, and the popularization and the application are easy.

Description

technical field [0001] The invention belongs to a seedling planting method, and in particular relates to a high-efficiency cultivation method of Magnolia magnolia. Background technique [0002] Guangyulan likes sunshine, and is also resistant to semi-shade conditions. It likes warm and humid climates. It also has a certain degree of cold resistance, and can withstand short-term low temperatures of 10 degrees without damage to the leaves. However, under long-term low temperatures of 12 degrees, the leaves will be damaged. freeze. Magnolia magnolia has a well-developed root system, and is most suitable for deep soil, fertile, moist, and well-drained soil. Avoid dry and calcareous soil, and it also grows poorly on poorly drained and alkaline soils. Magnolia magnolia has a beautiful tree shape, large and fragrant flowers, high ornamental value, strong ability to resist smoke, dust and poisonous gas, few pests and diseases, and medium growth rate. It is an excellent tree species...

Problems solved by technology

[0003] During the growth process, due to its own growth characteristics, after the seedlings are planted, the growth of the seedlings is slow in the early stage, and the growth of the tree vigor is always unsatisfactory due to improper control of the seedling density in the middle and later stages. In the process of growth and management, the competition between seedlings is fierce, competing for water, sunlight, and nutrient space. Magnolia magnolia itself is a tree with a large crown, large leaves, and lush branches. Strong positive tree species and fat-loving tree species, due to the competition between each body, and the demand cannot be met, resulting in the general growth of Magnolia magnolia in nurseries is not fast, and the benefits are not high
