摘要
对茶园土壤基本理化性状进行调查测定,结合茶树对养分的需求特性,合理配置有机无机肥料,比较了配方施肥与常规施肥对茶园土壤养分状况和茶叶产量与品质的影响。结果表明,与常规施肥相比,配方施肥后,养分总供应量得到减少,但茶园土壤养分供应更趋平衡,茶鲜叶产量增幅为1%-3%,并提高了茶鲜叶中的氨基酸含量,降低了酚氨比,同时获得了更高的产值,产值增幅为3%-6%。通过配方施肥,可减少因施肥不合理而造成的环境污染,提高肥料的利用率,更有利于茶叶的可持续生产,也符合当前茶叶生产中“减肥、减药”的大趋势。
The basic physical and chemical properties of the soil in local tea plantations were determined. Formulated and conventional fertilizations were applied for comparison on their effects on yield and quality of the teas grown with the applications. The results showed that the appropriately formulated fertilization （1） improved the balance on nutrients in soil reducing the demand of fertilizer; （2） increased the yield of tea shoots 1 % ？3 % as well as the amino acid content in the tea; （3） reduced the polyphenol/amino acid ratio of the tea; and, （4） raised the production revenue by 3% ？ 6% . Furthermore, it could also potentially mitigate the environmental pollution by advoiding over-fertilization and excessive runoff, as well as contribute to the sustainable agriculture through maximizing fertilization efficiency.
