Effects of different leaf positions and nitrogen fertilizer rates onchlorophyll content in leaves of Tieguanyin tea plants

摘要: 研究了铁观音茶树不同叶位和施氮量对叶片叶绿素含量的影响, 结果表明:第2、3位叶, 第5、6位叶和隔年老叶的叶绿素含量随叶片生长时间延长呈增加趋势;随着氮肥用量的增加, 百芽重、芽头密度和茶青产量随之增加, 叶绿素含量也呈增加趋势。

Abstract: Effects of different leaf positions and nitrogen fertilizer rates on chlorophyll content in leaves of Tieguanyin tea plants were studied in this paper. The results showed that along with the leaf growth, the chlorophyll contents in leaves at 2nd, 3rd leaf position, 5th, 6th leaf position and the two-years aged leaves increased. In addition, with the increase of nitrogen fertilizer, one-hundred-bud weight, budding density and tealeaves yield, as well as chlorophyll content also increased.
