Problems solved by technology

However, since the roof of a building has a certain load-bearing range, the thickness of the roof planting soil cannot be increased without limit, and most trees and shrubs have deep root systems and cannot be directly planted in the thinner soil on the roof, which greatly reduces the effect of roof greening landscape.

Abstract

The invention discloses a root guiding and seedling raising method of arbor species for roof greening. The method includes eight steps: manufacturing root resistance plates; screening seedlings; marking; cutting off bottom roots; placing the root resistance plates; cutting off side roots; fixing the seedlings; and lifting the seedlings and planting to finally obtain the arbor species with the soil ball diameter ranging from 40cm to 60cm for roof greening. The special seedlings suitable for roof greening are cultivated by guiding the seedling roots of the arbor species to extend along the horizontal direction during seedling raising, the seedlings are used for roof greening after transplanted, the method solves the problem of difficulty in plating large arbor species due to roof bearing limitation and shallow planter soil, so that roof greening construction level is improved, and roof greening landscape effects are enriched.

Description

technical field [0001] The invention relates to a root-guiding seedling raising method for arbor tree species used for roof greening, and belongs to the technical field of horticulture. Background technique [0002] Landscaping plays an irreplaceable role in improving the quality of urban environment, but the land for urban greening is extremely limited. Therefore, people have gradually changed the traditional greening method of planting on the ground, turned their attention to the sky, and started the exploration and practice of three-dimensional greening. Among them, the top of large-scale buildings has become the first choice for greening workers. However, since the roof of a building has a certain load-bearing range, the thickness of the roof planting soil cannot be increased without limit, and most trees and shrubs have deep root systems and cannot be directly planted in the thinner roof soil, which greatly reduces the effect of roof greening landscape. The present in...
