Embodiment Construction

[0022] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0023] The present invention will be further described in detail below in conjunction with specific embodiments.

[0024] The present invention is a method for cultivating a multi-layered modelling of white elm combined planting, and the method comprises the following steps:

[0025] 1) Cultivate white elm seedlings

[0026] The white elm seedlings are cultivated in the nursery in advance, the planting row spacing is 1m × 1m, and when the diameter at breast height reaches 1.5-2cm, the sap begins to flow in spring and then it is set to dry, which are 4 kinds of seedlings with a dry height of 80cm, 130cm, 180cm and ...

Abstract

The invention discloses a method for cultivating ulmus pumila in a multi-layer shape by combined planting. The method comprises the steps: cultivating ulmus pumila nursery-grown plants in a nursery garden in advance; determining a stem after sap starts to flow in spring, the stem height respectively being 80 cm, 130 cm, 180 cm and 230 cm for 4 nursery-grown plants; pruning every 2 months within a growing period of the nursery-grown plants; selecting ulmus pumila nursery-grown plants at different heights for combined planting at next spring; setting 3 main stems for inarching; and after inarching, fixing lateral branches and clipping at regular intervals. The method disclosed by the invention relates to a cultivating method using multiple ulmus pumila nursery-grown plants for combination, inarching and pruning, so as to develop the ulmus pumilain a multi-layer shape, shorten the cultivating period for shaped nursery-grown plants, and expedite cultivation of the special nursery-grown plants. The obtained ulmus pumila could achieve landscaping nursery-grown plant standards, the shape of the ulmus pumila could embody dynamic aesthetic feelings of gardening shaping, and enrich landscape architectures.

Description

technical field [0001] The invention relates to the technical field of horticultural modeling, in particular to a method for multi-layer modeling cultivation of combined planting of white elm. Background technique [0002] Ulmus pumila L. (Ulmus pumila L.) is a species of Ulmus genus, distributed in Northeast China, North China, Northwest China and Southwest China. It is resistant to cold and drought, has strong adaptability, and is a tree species with strong pollution resistance. Strong, dense branches, small leaves, green leaves, pruning resistance, suitable for trees and shrubs, it is a good modelling tree species in the northwest region. [0003] In the current landscaping, the shape of white elm mostly adopts the traditional coiling modeling method. This cultivation method is laborious, the crown shape is rough, the seedlings are easily injured and infected with diseases, and the seedling raising speed is slow, so it cannot be widely used in greening production. The me...
