Abstract

The invention belongs to the field of landscape greening plant cultivation, and particularly relates to a cultivation method for bunch-type gmelina-arborea-roxb big seedlings. The cultivation method for the bunch-type gmelina-arborea-roxb big seedlings includes the steps that cultivation is carried out with the seed clustering direct sowing method, seeds collected from fifteen-year-old robust gmelina-arborea-roxb seed trees are evenly sowed in seedling cultivating bags, self-made compound fertilizers are applied, and cultivating is carried out for 12 months, then the obtained seeds are transplanted into planting holes with the depth and the width of 40 cm, and from a second year after transplanting, inner-side branches are thinned from bases in winter every year, self-made compound fertilizers are applied, cultivating is carried out for 5 years, and seedlings can be transplanted to gardens. The bunch-type gmelina-arborea-roxb big seedlings cultivated with the method have the advantagesthat all primary branches of bunch seedlings are even in thickness and space distribution, complete and attractive in crown and high in transplanting survival rate, large-scale popularization and application can be achieved, and the cultivation method is an ideal cultivation method for the bunch-type gmelina-arborea-roxb big seedlings.

Description

technical field [0001] The invention belongs to the field of landscaping nursery stock cultivation, and in particular relates to a method for cultivating clustered Yunnan stone catalpa seedlings. Background technique [0002] Trees can generally be divided into trees and shrubs according to the attainable height of the tree body, the height of the branch point, and the thickness of the main branch and side branches. Trees are usually tall, with high branch points, and the thickness of main branches and side branches is significantly different. Shrubs are not more than 3 meters high, branch points are close to the ground, and the thickness of main branches and side branches is basically equal. Due to the high branch points of trees, they are often used to construct middle and upper garden space, but the space enclosure effect is not as good as that of shrubs. Cultivating the arbor into a shrub type, that is, a cluster-type arbor, can realize the enclosure function and create...
