以黄旦、福鼎大白茶、肉桂、毛蟹、铁观音鲜叶为原料,对其驻芽一、二、三叶进行力学特性及粗纤维含量的测定,研究表明,茶树嫩梢的弹性模量在4 158.88~14 849.11 kPa,最大应力在870.00~1 842.97 kPa,断裂应力在673.33~1 639.62 kPa,叶位对弹性模量、最大应力与断裂应力的影响达到极显著水平,大小排序为:三叶>二叶>一叶。茶树嫩梢最大力点应变在10.61%~18.36%,断裂应变在12.19%~26.95%,叶位对最大应力与断裂应力的影响达到极显著水平,大小排序为:三叶>二叶>一叶,不同品种有所差异。茶树嫩梢力学参数为茶叶加工机械设计提供了一定的参考价值。
The mechanical properties and the crude fiber content of the first, second and third leaves of Huangdan, Fuding Dabaicha, cinnamon, hairy crab, and Tieguanyin were determined. The results showed that the elastic modulus At 4 158.88-14 849.11 kPa, the maximum stress is 870.00-1 842.97 kPa, the fracture stress is 673.33-1 639.62 kPa, and the influence of leaf position on elastic modulus, maximum stress and fracture stress is extremely significant. The order of magnitude is Leaves> two leaves> a leaf. The maximum strain at the fresh shoots of tea plants was between 10.61% and 18.36% and the strain at break was between 12.19% and 26.95%. The effect of leaf position on maximum stress and stress at break was extremely significant. The size order was: Different varieties vary. The mechanical parameters of tea shoots provide some reference value for tea processing machinery design.
