A 5a (2009—2013) experiment was carried out to study the effects of different proportions of manure (litters in the microbial fermentation bed in pig farm) and chemical fertilizer on the distribution of active aluminum forms (exchangeable aluminum [Al³⁺, Ex-Al], unimer hydroxyl aluminum [Al(OH)²⁺ and Al(OH)₂⁺, Hy-Al], acid-soluble aluminum [Al(OH)₃⁰, Col-Al], humic acid aluminum[HA-Al]) in tea garden soil and aluminum concentration in tea, and then the feasibility of applying manure to improve acidified soil in tea garden and reduce Al concentration in tea was also discussed. Five treatments were designed: total chemical fertilizer without manure (CK), 25% of chemical fertilizer replaced by manure, 50% of chemical fertilizer replaced by manure, 75% of chemical fertilizer replaced by manure, and total manure. The results showed that, compared with CK, pH and organic carbon increased by 0.27-1.05 units and 8.64%-30.71% in 0-20 cm soils and by 0.16-0.50 units and 0.94%-14.84% in 20-40 cm soils in the treatments with organic manure, respectively. With the increase of manure proportion, the contents of of total active aluminum (ΣAl) in tea garden soil showed a decreasing trend, the contents of Ex-Al, HA-Hl and their ratios in active ΣAl were decreased, the contents of Hy-Al and its ratio in active ΣAl were increased, and the content of Col-Al remained stable but its ratio in active ΣAl was enhanced. Al concentration in tea was ranged from 820.04 to 940.27 mg/kg in all treatments, but no significant difference was found in Al concentration in tea between different fertilization treatments. In conclusion, the application of organic fertilizer can increase soil pH and organic matter, thus promote the transformation of exchangeable Al³⁺(Ex-Al) to hydroxyl aluminum(Hy-Al), but have no significant effect on Al concentration in tea. So, the feasibility needs further study to reduce Al concentration in tea by improving soil acidity with the application of organic manure.
