The purpose of this study were to investigate the TTES No. 18 black tea plant growth responses under different tillage systems and combined with application of different water absorbent dosages and impact on soil nutrient elements in order to find the best application combination of cultural system and water absorbent treatments dosage. The results can improve the quality of tea, water-saving on irrigation and less amount of fertilizer applications. Two different cultivation methods (sod culture and clean cultivation) as well as different amount of water absorbent agent (0,125,250 and 375 g g/5.04m2) treatment combinations were tested. The test results showed that: application of water absorbent treatment increased number of tea buds,promote leaves length, leaf width and leaf area growth. The bud leaf length under 125 g/5.04m2 water absorbent treatment increased 0.44 cm, the first leaf width and leaf area increased (0.16 cm and 1.03 cm2) under 375 g /5.04m2 treatment. The second leaf length increased 0.81 cm under 250 g/5.04m2 treatment. The second leaf width and leaf area increased (0.35 cm and 2.93 cm2) under 375 g/5.04m2. Shoots fresh weight increased 162.5 g under 125 g/5.04m2 treatment. Sod cultivation significantly increased fresh weight of bud 245.31 g/5.04m2 as compared to the clean cultivation. Although there is no significant differences on the remaining afronomic traits, but applying water absorbent all showed better performances. It is recommended to apply 375 g/5. 04m2 water absorbent implement in sod cultivation of tea plantation, thus can improve the production of tea and effectively maintain higher nutrient content in the soil.
