Abstract: In order to explore the pig fermentation bed padding applied to the influence of the tea tree growth, to carry out the field experiments, research on base fertilizer application with fermentation bed padding using 0, 20, 40 t/hm2, top dressing nitrogen of 0, 67.5, 135.0 kg N/hm2 in spring to tea plant photosynthetic characteristics and the influence of tea production. The results showed that the application of fermentation bed padding processing , improve the tea tree net photosynthetic rate, chlorophyll content and tea tree, but no obvious difference (P>0.05); Top dressing of nitrogen fertilizer significantly increased tea plant chlorophyll content and tea net photosynthetic rate (p < 0.05), increase rate increases with the increase of nitrogen. Fermentation mattress is expected to significantly improve top dressing nitrogen fertilizer, fresh tea tea production (p<0.05), Interaction of mattress material and nitrogen fertilizer in tea production was not significant (p>0.05). Comprehensive Treatment, medium fermentation mattress material with the conventional surueyed nitrogen treatment (T5) tea tree leaf chlorophyll content, net photosynthetic rate and tea production is the highest , suitable for tea garden fertilizer.
