Method for rapidly forming big tree by multi-point approach grafting of gingko seedlings, rapidly-formed big tree and application thereof

Abstract

The invention provides a method for rapidly forming a big tree by multi-point approach grafting of gingko seedlings, a rapidly-formed big tree and an application thereof, relating to the technical field of landscape plant cultivation. The method comprises the following steps: forming the shape of the big tree with at least two young gingko seedlings aged from 2 to 5 years, removing barks of approach grafting parts of a gingko such that phloem is exposed and smearing a layer of healing agent to the exposed part; binding the young gingko seedlings such that the seedlings grow like the shape of the big tree; and culturing the young gingko seedlings for 1-2 months so that an approach grafting healing surface of trunks between the young gingko seedlings can be firmly healed. According to the conventional mode, a big tree is formed by grafting and winding methods. However, it always takes one growth season or one year without ensuring that the big tree is healed. The method helps notably increase healing efficiency. The adult big tree grows integrally so as to resist cold and heat. Ultimately, the tree is healed without four weeks due to modeling and grows quickly into the big tree. Therefore, the purpose of making landscape architecture is achieved.

Description

technical field [0001] The invention relates to the technical field of landscape plant cultivation, in particular to a method for connecting ginkgo seedlings to fast-growing large trees at multiple points, the prepared fast-growing large trees and applications thereof. Background technique [0002] Ginkgo trees are tall and straight, with fan-shaped leaves. The crown is shade-shaped and has a cooling effect. The leaf shape is quaint and has a long lifespan. It has no pests and diseases, does not pollute the environment, and has smooth trunks. It is a famous pollution-free tree species, which is conducive to the reproduction of ginkgo and adds to the scenery. At the same time, ginkgo is also a commonly used tree species in Chinese bonsai. Ginkgo bonsai has thick stems, curved branches, and exposed roots. It has a unique shape, vigorous and chic, and full of fun. It is vigorous and green in summer, and golden in autumn, giving people a sense of steepness, majesty, luxury an...

Problems solved by technology

[0003] With the development of society and economy, the demand for ginkgo trees for greening is increasing in domestic and foreign markets. Especially in recent years, cities have been engaged in greening, and many large trees have been transplanted from various villages into cities. Usually, these large ginkgo trees are used The materials are all taken from the old forests in the deep mountains or the trees in front of and behind the houses in the countryside. The practice of digging and transplanting these ancient trees directly on the greening site has seriously damaged the ecological balance of nature, and the gains outweigh the losses.

At the same time, due to the increasingly stringent environmental protection and plant protection policies in recent years, the above methods have been far from meeting the needs of urban greening construction for various dry trees.

[0004] In recent years, in order to meet the needs of urban landscaping construction, people have also come up with many methods to shorten the cultivation cycle of ginkgo landscape trees. It often takes one growing season or one year for the healing of the healing surface, and generally the healing is incomplete; resulting in the formation of Under the resistance of big trees to wind, rain, cold and heat, the forming effect of big trees is poor

[0005] Therefore, it is very necessary to research and develop a method that can quickly grow large trees in a natural environment, and effectively alleviate the problems of long forming time, low success rate, and poor resistance to nature in the existing rapid prototyping methods of ginkgo landscape trees. and urgently
