Abstract

Through field test by setting factors of nitrogen level and organic/chemical fertilizer ratio, we studied the effects of different fertilizer application systems on organic matter and nitrogen nutrition in tea garden soil, as well as tea yield & quality were investigated. The results showed that contents of organic matter and total nitrogen were significantly increased under all various fertilizer treatments, and applying 75% organic manure combined with 25% chemical fertilizers with 900βkg·hm^-2 high nitrogen level exhibited the most remarkable increasing effects. Compared with no fertilization treatment, indicators of tea production including the bud-leaf density, 100-bud weight were increased under all various fertilizer treatments. Furthermore, the quality indicators of spring tea were dramatically increased under such fertilizer treatments that organic manure more than 25%, the tea quality improved more while organic manure was more than 50%.
