摘要: 采用田间试验和调查,对茶树体内硫的分布特征及施硫对茶叶产量和品质的影响进行了研究。结果表明,茶树体内以吸收根和新梢等生命活动旺盛的部位硫含量较高,成熟叶片次之,主干和主根硫含量最低;施硫后茶树吸收根和新梢硫含量显著提高,而主根和主干变化不大。新梢一芽二叶硫含量(Y)与土壤有效硫含量(X)呈极显著正相关(Y=5.6043X+1903.6,P<0.001)。幼龄茶树施硫后树高、树幅、主干直径、分枝数、百芽重等均有显著增加。成龄茶园施硫后增产幅度在–2.1%~25.0%之间,平均10.8%;茶叶品质成分氨基酸、茶多酚和水浸出物含量有不同程度提高,其中氨基酸提高明显,酚氨比降低。从施硫增产幅度与施硫前土壤有效硫含量的函数关系式得出茶园土壤缺硫临界值为27.4 mg·kg-1。使用硫磺粉能明显提高表层土壤有效硫含量,但土壤pH降低,且随施硫量的增加,pH降幅增大。因此,科学合理施硫对于促进茶叶生产的持续健康发展十分必要。

Abstract: :By using field experiment and survey, the characteristics of sulphur (S) distribution in tea plant and the effect of S application on tea yield and quality were studied. The results showed that S was mainly distributed in the active parts of tea plant, such as new shoots and feeding roots, followed by mature leaves, trunk and main roots were among the lowest. S contents in shoots and feeding roots were significantly increased after S application.

Key words: tea plant, sulphur, distribution characteristics, S deficient threshold, tea yield, quality
