Old and famous tree growth retardant and conveying method and device thereof

Abstract

The invention relates to the technology of delaying growth of plants and discloses an old and famous tree growth retardant, a conveying method thereof and a conveying device thereof. The old and famous tree growth retardant mainly comprises paclobutrazol, chlormequat chloride, daminozide and water and inhibits the biosynthesis of GA in plant bodies to inhibit the growth of plant sub-apical meristems, delay the elongation and growing speed of cells and then delay the growth. The growth retardant is injected into the tree bodies through a conveying device with simple and safe operation, and theenvironments and safety of special occasions, such as classical gardens and the like, are ensured. A cylindrical sponge body of an absorber is embedded in a tree trunk, so the maximal absorption areais achieved after the retardant is infused into the tree trunk, the retardant can be uniformly and quickly diffused into conveying and guiding tissues on the peripheral surfaces of round holes, the absorption of the infused liquid is quickened. The liquid in the holes can be effectively prevented from losing due to a rubber hole plug of the absorber, so the utilization efficiency of the retardantis improved.

Description

technical field [0001] The invention relates to a plant growth retardation technology, in particular to a growth retarder, a delivery method and a device for controlling the growth of ancient and famous trees growing in a special environment. Background technique: [0002] Ancient trees and famous trees are the main protection objects of my country's classical garden heritage. Only in the eight classical gardens in the ancient city of Suzhou that have been included in the "World Cultural Heritage List" have 86 ancient and famous trees. Most of these ancient and famous trees are old. For more than a hundred years, the volume of some ancient trees is too large, which exceeds the space requirements of the garden landscape, or exceeds the bearing capacity of the rhizosphere environment on the tree body. However, these ancient and famous trees are not only important landscapes of classical gardens, but also the main protection objects of garden heritage. The growth of trees canno...

AI Technical Summary

Problems solved by technology

The study found that most of the roots of super-sized ancient and famous trees in classical gardens are paved with bricks, stones, etc. or grow among rocks in rockeries, and it is difficult to use conventional soil application methods for growth retardants; Both are open to tourists and environmental pollution issues, and it is not suitable to apply growth retardants by foliar spraying
