The ancient trees refer to trees with ages of more than 100 years, are valuable resources which are rare in number and can not be regenerated, bear abundant natural, historical and cultural information, and are witnessed persons with alternative urban histories and biological resources which are not replaced by urban landscapes. The ancient tree records the climate change of a region, witnesses the development process of a city, has the American name of living cultural relics, has extremely high values of humanity, ecology, society and economy, and has important scientific research, travel ornamental, geographic coordinates and historical commemorative significance.
With the rapid development of Chinese economy, the foundation construction scale is continuously enlarged, old urban reconstruction, municipal road widening, and expressway construction inevitably affect ancient trees growing along the line, and a large number of ancient trees face the problem of migration protection. The ancient tree transplanting must comprehensively consider the influencing factors in various aspects, the ancient tree grows in one place for a relatively long time, and the ancient tree is suitable for the factors of local environment, air temperature, humidity and the like, so that the transplanting can be damaged. In order to ensure that the ancient trees in the transplanting process are not damaged greatly, the transplanting technology difficulty is higher than that of general trees, and the technology is advanced and fine. The reconstruction and recovery of root systems are key to the survival of transplanted ancient trees, and in the prior art, a rooting liquid root irrigation mode prepared by naphthalene acetic acid or indolebutyric acid and other rooting promoting substances is often adopted to achieve the purpose of promoting the rooting of transplanted ancient trees. The plant rooting agent is absorbed by the soil around the root of the ancient tree after root irrigation, so that the rooting agent cannot continuously act on the broken root forming layer, and along with the increase of root irrigation times, the growth regulator enriched in the soil can also inhibit the growth of the root system, thereby causing the poisoning of the root system of the ancient tree.
In order to improve the transplanting survival rate of the ancient trees and provide references and bases for transplanting other big trees and precious tree species, the invention researches a method for improving the transplanting survival rate of the ancient trees by combining experimental comparison data in a large amount of ancient tree transplanting practical experience.
