Abstract: Through field experiment, the effects of fertigation on the growth, nutrient absorption and quality components of young tea plants of Longjing43 and Baiye 1 were studied. We also compared the input costs under different fertilization patterns. The results show that the tea plant growth including tree height, trunk diameter and canopy width increased significantly under fertigation, even if the chemical fertilizer was reduced by 25%, compared with conventional furrow fertilization, and pruning biomass and nutrient uptake also increased significantly. At the same time, nutrient leakage loss was significantly reduced and nutrient use efficiency was improved. From the analysis of the times of fertigation, it could achieve better results by applying fertilizer 7 times per year under the experimental conditions for Longjing 43, and 14 times per year for Baiye 1.

Key words: fertigation, biomass, tea quality components, nutrient absorption
