充分发挥茶园碳汇功能，促进茶叶低碳生产发展

在全球气候变化已引起世界各国关注的今天，发展低碳经济，采用可持续的低碳农业技术措施发展低碳农业，是解决气候变化与经济发展矛盾的有效途径。本研究介绍了茶园碳汇功能：茶树生长对空气中CO2的固定和茶园土壤碳库对有机碳的富积和保存。总结中国茶叶生产实践和茶叶科学研究过程中形成的低碳茶叶生产技术：因地制宜合理规划、合理开垦防止烧山垦园、合理密植因缺补缺、平衡施肥促进茶树无机有机物质循环过程的进程、立体栽培增加茶园生物多样性、免耕或减耕减少土壤碳排放、增施有机肥提高土壤C/N率等；提出提高茶农对低碳的认识、建立茶叶低碳生产示范园区、加强对茶叶生产低碳技术的研究、大力发展有机茶、政府政策导向支持等促进茶叶低碳生产发展建议。采用低碳生产技术，挖掘茶园生态系统的碳汇能力，增加茶园系统碳储量，必将对减少温室气体排放做出重大贡献。

Increasing Tea Garden Carbon Sink Capacity, Promoting the Development of Low Carbon Tea Production

During the times that global climate change has caused extensive concerns of the countries all over the world,developing the low carbon economy and the low carbon agriculture basing on sustainable and low carbon agricultural technology was an effective way to resolve the contradiction between climate changing and economic development.This paper described the function of tea garden as sink of carbon containing the CO 2 from the air fixed by the growing tea trees and the organic carbon sequestrated by tea soil carbon pool.It summarized the techniques on low carbon tea production based on the actual experience of tea production and scientific research.It should be adjusted measures to local conditions and should be rationally planned when reclaim new tea garden.Reclaiming land should be rational and forbid burning.It should be rational close planting and replenishing which lack in dire need.It should be balanced fertilization in order to promote the cycle of tea organic and inorganic carbon and using cultivation of three dimensions to increase the biodiversity,using zero and reduced tillage to decrease the carbon emission from soil,increasing organic manure to raise soil C/N ratio.It should improved the knowledge of low carbon,found low carbon demonstration tea garden,strengthen research on low carbon technology,devote major efforts to developing organic tea,and enhance the policy direction to support and promote low carbon tea production.Adopting low carbon technologies,exploiting the carbon sink potentialities of tea ecosystem,and increasing tea ecosystem carbon storage,all of which could gaven a significant contribution on reducing emissions.
