Mutualism and minimally invasive docking method of wild alpine Rhododendron ancient stump and modern cultivated species

Abstract

The invention relates to a mutual assistance symbiosis minimally-invasive inarching method for wild alpine rhododendron ancient stumps and modern cultivars. The method includes the following steps that A, the root systems of the wild alpine rhododendron ancient stumps are processed, and soil around the root systems of ancient trees is scarified and planed, and the roots are exposed; B, the seedlings of the modern cultivars are inarched on the peripheries of the ancient stumps in an encircling mode, and the root systems of inarched plants are made to make close contact with the root systems of the ancient trees as much as possible; C, after the inarching is completed, filling is performed by using the original soil or prepared growth matrix; D, the plants are watered thoroughly for the first time, the root bulbs are fully wetted and repaired. With the mutual assistance symbiosis minimally-invasive inarching method for wild alpine rhododendron ancient stumps and modern cultivars, the inarched plants have a mutual assistance symbiosis relationship, all the organs such as roots, stems and leaves of independent plants are reserved respectively, but the plants depend on one another and are symbiotic in a mutual assistance mode to form a whole.

Description

technical field [0001] The invention relates to a mutual-assisted symbiotic minimally invasive docking method between wild alpine Rhododendron ancient stumps and modern cultivars, which belongs to the technical field of plant cultivation and is mainly used for in-situ treatment and ex-situ transplantation protection of alpine Rhododendron ancient stumps. Background technique [0002] Rhododendron is the most valuable ornamental flower in the world. It is called "the beauty of flowers" and is listed as one of China's top ten famous flowers. Alpine Rhododendron is a fine product in the Rhododendron family, with extremely high ornamental and economic value. In the wild distribution area of ​​Alpine Rhododendron, the root systems of many wild alpine Rhododendron stumps have been damaged to varying degrees due to various reasons such as climate, geography, or man-made reasons. The habitat is suitable for continued growth, or because of the age of the trees or the important geogr...

AI Technical Summary

Problems solved by technology

For the wild alpine Rhododendron ancient tree stumps collected from mountains with an altitude of three or four thousand meters, the root system of the ancient tree is huge, and the root system had to be cut off from the base when digging. The functional capillary roots that absorb nutrients are stretched far from the root tip, and the truncated root system has almost no trace of capillary roots, which brings great difficulties to the root system of plants in different places; Conditions are no longer suitable for the growth of wild alpine Rhododendron stumps for treatment? How to improve the success rate of in situ conservation and the survival rate of ex situ conservation of wild alpine rhododendron stumps? There are currently no published literature reports
