摘要:
本研究以3年生盆栽茶树品种中茶302为试验材料,系统探究以南瓜为主要原料制备的植物酵素叶面肥喷施对茶树新梢生长及茶叶主要品质成分的影响。采用单因素试验,设置不同稀释倍数的植物酵素叶面肥喷施处理(T1～T3)与清水喷施对照(CK),通过对茶树新梢生长指标、茶叶主要品质成分含量的测定与分析,明确其作用效应。研究结果表明,与CK相比,稀释50倍的植物酵素叶面肥处理可显著促进茶树新梢生长,新梢百芽重和叶面积分别提升39.67%和58.89%，同时该处理显著降低了茶叶中咖啡碱含量。进一步研究发现,茶叶中氨基酸含量和茶多酚含量随植物酵素稀释倍数的降低呈现先升后降的变化趋势。从品质成分角度分析,与CK相比，稀释50倍的植物酵素处理可显著降低苦味成分表没食子儿茶素没食子酸酯(EGCG)含量、表儿茶素没食子酸酯(ECG)含量、表儿茶素(EC)的含量,同时显著提高鲜爽味氨基酸组分茶氨酸、谷氨酸、丝氨酸、丙氨酸的含量。本研究结果揭示了南瓜基植物酵素叶面肥对茶树生长及茶叶品质的调控作用,为茶树绿色高效施肥技术的研发提供了理论依据,对推动茶园可持续发展具有重要实践意义。
Abstract:
This study utilized three-year-old potted tea plants of the cultivar Zhongcha 302 as experimental materials to systematically investigate the effects of foliar spraying with plant enzyme fertilizer, prepared primarily from pumpkin, on the growth of young shoots and the key quality constituents of tea leaves. A single-factor experiment was conducted, involving treatments with plant enzyme foliar fertilizer at different dilution ratios (T1-T3) and a control group sprayed with water (CK). By measuring and analyzing the growth indicators of tea shoots and the content of key quality components in the leaves, the effects of the treatments were clarified. The results indicated that, compared with CK, the treatment with plant enzyme foliar fertilizer diluted 50-fold significantly promoted the growth of new tea shoots, resulting in increases of 39.67% and 58.89% in the hundred-bud weight and leaf area, respectively. Meanwhile, this treatment also significantly reduced the caffeine content in the tea leaves. Further research revealed that the contents of amino acids and tea polyphenols in the leaves showed an initial increase followed by a decrease as the dilution ratio of the plant enzyme decreased. From the perspective of quality components, compared with CK, the treatment with plant enzyme diluted 50-fold significantly reduced the contents of the bitter-taste components epigallocatechin gallate (EGCG), epicatechin gallate (ECG), and epicatechin (EC). Meanwhile, it significantly increased the contents of amino acids associated with freshness, including theanine, glutamic acid, serine, and alanine. The findings of this study elucidate the regulatory effects of pumpkin-based plant enzyme foliar fertilizer on tea plant growth and tea quality, providing a theoretical foundation for the development of green and efficient fertilization techniques in tea cultivation. This work holds significant practical implications for promoting the sustainable development of tea gardens.
