Investigation On The Growth Condition Of Ancient Tree Group And Formulation Of Protective Management Technology In Dai Temple

Ancient and famous trees are important natural resources,which have scientific,historical and cultural values with long history.Dai Temple,an important part of the Taishan tourist spotis,is a key national heritage conservation unit.There are 222 ancient trees in Dai Temple’s Ancient Tree Communities,of which over 90% are Platycladus orientalis,and a small number of Chinese scholar tree,Ginkgo biloba and China Savin.Ancient trees enrich the cultural connotation of Dai Temple and increase the fun of tourists.However,with the economic development and urbanization construction,the growth of the Ancient Tree Communities in Dai Temple has been affected.It is urgent to protect ancient trees,and it is necessary to find out the factors affecting the growth of ancient trees in order to better manage them after day.Therefore,to understand the basic situation of Dai Temple Ancient Tree Communities and analyze the influencing factors,so as to summarize the protective management methods for daimiao ancient tree group is the problem to be studied in this paper.This paper mainly studies the growth status of Ancient Tree Communities in Dai Temple,and then finds out the factors affecting the healthy growth of ancient trees to carry out targeted management and protection.Finally,this paper proposes technical suggestions on protective management to guide the daily maintenance work.The main findings are as follows:1.There are two hundred and twenty-two extant ancient trees,most of which are Platycladus orientalis,as well as part of Chinese scholar tree,Ginkgo biloba and China Savin.Among them,19.8% are first-class ancient trees aged over 500 years,3.6% are second-class ancient trees aged 300-500 years,and 76.6% are third-class ancient trees aged 100-300 years.2.According to the results of external morphological health evaluation of the ancient trees,there are 35 ancient trees with growth status of superior class,70 in the good class,51 in the general class,and 19 in the debilitated class.The overall growth state is relatively good.3.According to the soil survey,the soil quality of Dai Temple’s Ancient Tree Communities is poor and alkaline.The soil texture is relatively compact and hardening.The content of available potassium is too low,while the content of calcium,magnesium and other heavy metal ions is too high,which affects the growth and development of ancient trees.Within the area where the old trees are concentrated,the soil condition of the old trees in the central courtyard of the Tian Kuang Hall is the poorest.In the follow-up work,it is necessary to further improve the soil and the surface environment in Dai Temple to improve the living environment quality of ancient trees.4.This review summarizes the protective management plan of the Ancient Tree Communities in Dai Temple,which mainly aims at the daily maintenance of the Ancient Tree Communities,the control of diseases and pests,rejuvenation measures in the aerial parts,the improvement of the subsurface environment,and the remediation of the ancient tree.5.During the course of investigation,it was found that there was insufficient conservation of the ancient tree groups in Dai Temple,and some tourists caused some harm to the Ancient Tree Communities during their tour,making the Ancient Tree Communities produce unnecessary losses.In the future,Dai Temple can improve tourists’ conservation awareness by promoting the historical cultural value of the ancient tree group,while at the same time making a good post patching work to minimize unnecessary loss of the ancient tree group.6.During the investigation process of this research,many ancient trees suffered from broken branches due to severe weather,and even died due to broken trunks.In the future work,attention should be paid to the protection of the Ancient Tree Communities in the coming of bad weather such as typhoons,thunderstorms,and the remediation work of the ancient trees after bad weather.Through the investigation and analysis of the Dai Temple Ancient Tree Group,technical management of ancient trees and management suggestions for the landscape area of the Ancient Tree Group are presented.
