不同间作物对茶树新梢营养元素的影响

[目的]研究不同林茶间作模式下间作物对茶树新梢营养元素的影响,为茶叶品质的改善和提高提供参考依据.[方法]以单作茶园的一芽二叶茶叶新梢蒸青样为对照,不同间作茶园的一芽二叶茶叶新梢蒸青样为材料,对其营养元素含量进行测定.[结果]3种林茶间作模式中的茶叶新梢N、P、K、Ca、Mg、S、Cu、Zn、Fe、Mn、Mo等元素含量与单作茶园相比均有一定的变化,但变化趋势和大小不一致.在3种林茶间作模式中茶叶新梢均增加的元素是K、Ca、Mg、Fe,减少的元素是P、Mn.[结论]3种间作模式增强了茶树新梢对营养元素的吸收,提高了茶叶品质.

Effect of different intercrops on nutrient elements content in new shoots of tea tree

[Objective]Effects of different intercrops on nutrient elements content in new shoots of tea tree was studied to provide references for improving the quality of tea leaves. [Method]Nutrient elements content in one-bud and two-leaf shoots of tea tree were determined based on different intercropping patterns on three different plants (wild pepper-tea, agilawood-tea, camphor tree-tea), using one-bud and two-leaf shoots under mono-cropping as control. [Result]Compared with control, the contents of N, P, K, Ca, Mg, S, Cu, Zn, Fe, Mn, Mo and other elements in new shoots under three different intercropping patterns had certain change with varied change tendency; the contents of K, Ca, Mg and Fe increased in the three intercropping patterns, while the contents of P and Mn dwindled. [Conclusion]The three intercropping patterns could boost the absorption of nutrients in tea shoots and improve the quality of tea leaves.
