施用碱渣对茶园土壤酸度和茶叶品质的影响
Effect of Alkaline Slag Application on Acidity of Tea Garden Soils and Tea Quality.
摘要
Abstract
A field experiment was carried out to investigate effect of application of alkali slag on acidity of tea garden soils and tea quality. Results indicate that application of alkali slag increased soil pH, soil exchangeable base and base saturation; and decreased soil exchangeable acid and exchangeable Al, thus keeping Ca and Mg in the soil in a rational ratio.Application of alkali slag increased the contents of tea polyphenols, catechin, theine, amino acid and chlorophyll in the tea produced from the tea garden, decreased the content of Pb in the tea, thus improving tea quality. The application of 4 500 kg · hm-2 alkali slag can adjust soil acidity to pH 5. 51, the most favorable for tea plant growth and production of tea of highest quality, in which the contents of tea polyphenols, catechin, theine, amino acid and chlorophyll were 22. 5％, 27. 8％, 34. 9％, 69. 0％ and 52. 1％, respectively, higher than in the tea produced in CK, while the content of Pb was 51.2％ lower.关键词
