摘　　要：高山茶通常产自海拔800m以上的茶山,西藏波密县高山茶园海拔在2200~2850m,海拔高和光照充足有利于茶叶进行光合作用,昼夜温差大有利于养分的储存,由于茶树生长环境土壤肥沃,雨量充沛,云雾多,光照经过云雾过滤后,时间和强度削弱,漫射光增多,有利于茶树生长和营养物质的积累。但是,波密县高山茶园茶树越冬容易遭遇低温天气的影响,而且持续时间长,导致波密县个别高山茶园茶树生理机能被破坏,茶树不能正常生长,茶树发生冻害,严重影响茶叶的产量和经济效益。针对波密县高山茶园越冬遇到的冻害问题,通过广泛调查及认真分析研究,形成了一套适用于高山茶园茶树防冻害的关键技术,对于提高高山茶园产量、增加茶农收入、提升茶叶品质、推动波密茶产业高质量发展将起到积极的作用。High mountain tea is usually produced on tea mountains with an altitude of over 8oo meters.The Bomi high mountain tea garden is located at an altitude of about 2200-2850 meters.The high altitude,sufficient sunlight,and large temperature difference day and night are conducive to the storage of nutrients.The fertile soil,abundant rainfall,and frequent clouds and fogs in the tea tree growth environment lead to weakening of light intensity and the increase of diffuse light,which is conducive to the growth of tea trees and the accumulation of nutrients.However,the tea trees in Bomi high mountain tea garden are prone to low temperature weather during the winter,which lasts for a long time,leading to the destruction of the physiological functions of tea trees,abnormal growth,and frost damage,severely affecting the tea yield and economic benefits.This paper focuses on the frost damage problem encountered by the high mountain garden in Bomi County during winter.Through extensive investigation,careful analysis and research,and summarization of experience,a set of key technologies for frost prevention in high mountain tea gardens has been formed.This will play a positive role in improving the yield of high mountain tea gardens,increasing the income of tea farmers,enhancing the tea materials and quality,and promoting the high-quality development of the Bomi tea industry.
