Abstract:

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 is 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 CO2 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 improve 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 give a significant contribution on reducing emissions.
