Embodiment 1
[0026] This technology was applied to the Foye Temple in Mount Tai, Tai'an City, Shandong Province, and the ancient ginkgo biloba in Hujiahe, Luoyang Town, Suizhou City, Hubei Province. The branches and leaves of the ancient trees turned green in the second year, and the growth and development were normal. The effect is very good. The implementation steps of the technique of rejuvenating ginkgo by inserting skin tongue and grafting ancient trees are as follows:
[0027] 1. Preparation for grafting
[0028] The grafting tools prepared include: grafting knife, pruning shears, pruning saw, axe or knife, grafting paper, special plastic film for grafting bundles.
[0029] 2. Pretreatment of the growth environment of ancient trees before grafting
[0030] Before grafting, clean up the debris around the ancient ginkgo (stones, bricks, cement, lime, weeds, sprouts, etc.), loosen the soil around the ancient ginkgo, and water properly. For areas with exposed rocks, guest soil improvem...

The invention discloses an ancient tree rejuvenation technology based on inverted bark-whip grafting for ginkgobiloba. According to the invention, a young seedling which is 3-5 years old and is good in growth condition, advanced in root system and free from diseases and pests is taken as a scion, an ancient ginkgobiloba tree which has a rot root system and weak in growth condition is taken as a tree stock, and an inverted bark-whip grafting method is applied to solve the rejuvenation problem of the ancient ginkgobiloba trees which are aged more than one hundred of years, are seriously damaged and have the root systems losing activity basically and solve problems which cannot be solved by using methods such as hole filling, pruning, soil replacement for root parts, fertilization and nutrient solution spraying in an ancient ginkgobiloba protection process. According to the ancient tree rejuvenation technology, the grafting principle is utilized to make phloems and cambiums of the ancient and young ginkgobiloba trees in complete butt-joint, the root system of the young ginkgobiloba seedling is used to replace the death root system of the ancient ginkgobiloba tree to be saved for absorbing nutrition and water so as to meet the growth requirements of the ancient tree, and the ancient tree rejuvenation technology has an obvious effect for the ancient ginkgobiloba trees which are aged more than one hundred of years, are seriously damaged and have the root systems losing activity basically, are simple and convenient to operate and are feasible.
Description
technical field [0001] The invention belongs to the technical field of rejuvenation of ancient and famous trees, in particular to a technique for rejuvenating ancient trees by inserting ginkgo upside-down with skin and tongue. Background technique [0002] Ginkgo biloba (Ginkgobiloba) belongs to the Ginkgo family, Ginkgo genus, deciduous trees. It is a relic plant preserved after the Quaternary glaciers. It is called a "living fossil" and belongs to the rare plant under the second-class protection of the country. Ginkgo biloba integrates edible, medicinal, material and ornamental uses, and has high scientific research value in paleobotany, plant taxonomy, plant comparative morphology, plant anatomy, embryology and fruit cultivation. In my country, from Shenyang in the north, to northern Guangdong in the south, to Ili in Xinjiang in the west, to Linjiang in Jilin and Taipei in Taiwan in winter, with Jiangsu, Anhui, and Zhejiang as the cultivation centers. Japan, Europe and ...
