Abstract

In this study, the performance of a novel organic tea compost developed for the first time in the world from raw tea waste from tea processing factories and enriched with worms, beneficial microorganisms, and enzymes was tested in comparison to chemical fertilizers in tea plantations in Rize and Artvin provinces, where the most intensive tea cultivation is carried out in Turkey. In the field trials, the developed organic tea vermicompost was incorporated into the root zones of the plants in the tea plantations in amounts of 1000 (OVT1), 2000 (OVT2) and 4000 (OVT4) (kg ha-1). The experimental design included a control group without OVT applications and positive controls with chemical fertilizers (N: P: K 25:5:10, (CF) 1200 kg ha-1) commonly used by local growers. The evaluation included field trials over two years. The average yields obtained in two-year field trials in five different areas were: Control (6326), OVT1 (7082), OVT2 (7408), OVT4 (7910), and CF (8028) kg ha-1. Notably, there was no significant statistical difference in yields between the organic (at 4000 kg ha-1 ) and chemical fertilizers (at 1200 kg ha-1). The highest nutrient contents were obtained when CF and OVT4 were applied. According to the average values across all regions, the application of OVT4 increased the uptake of 63% N, 18% K, 75% P, 21% Mg, 19% Na, 29% Ca, 28% Zn, 11% Cu and 24% Mn compared to the control group. The application of chemical fertilizers increased the uptake of 75% N, 21% K, 75% P, 21% Mg, 28% Na, 27% Ca, 30% Zn, 18% Cu and 31% Mn compared to the control group. The organic fertilizer treatment had the lowest levels of antioxidants compared to the control groups and the chemical fertilizers. It was also found that the organic fertilizer increased the levels of amino acids, organic acids and chlorophyll in the tea plant. Its low antioxidant activity and proline content prepared them for or protected them from stress conditions. With these properties, the biotechnologically developed organic tea compost fertilizer has proven to be very promising for tea cultivation and organic plant production.

新型生物技术蛭石堆肥对茶叶产量、植物营养成分、抗氧化剂、氨基酸和有机酸的影响，可替代化肥，实现可持续发展

在这项研究中，在土耳其茶叶种植最密集的里泽省和阿尔特温省的茶园中，对世界上首次利用茶叶加工厂的茶叶原料废料并添加了蠕虫、有益微生物和酶的新型有机茶叶堆肥与化肥的性能进行了比较试验。在田间试验中，开发的有机茶叶蛭肥以 1000（OVT1）、2000（OVT2）和 4000（OVT4）（公斤/公顷）的用量施入茶园植物根部。实验设计包括不施用 OVT 的对照组和施用当地种植者常用化肥（氮：磷：钾 25:5:10，（CF）1200 千克/公顷）的阳性对照组。评估包括为期两年的田间试验。在五个不同地区进行的两年田间试验的平均产量为对照（6326）、OVT1（7082）、OVT2（7408）、OVT4（7910）和 CF（8028）公斤/公顷。值得注意的是，有机肥（每公顷 4000 千克）和化肥（每公顷 1200 千克）在产量上没有明显的统计学差异。施用 CF 和 OVT4 时养分含量最高。根据所有地区的平均值，与对照组相比，施用 OVT4 增加了 63% 的氮、18% 的钾、75% 的磷、21% 的镁、19% 的钠、29% 的钙、28% 的锌、11% 的铜和 24% 的锰的吸收。与对照组相比，施用化肥增加了 75% N、21% K、75% P、21% Mg、28% Na、27% Ca、30% Zn、18% Cu 和 31% Mn 的吸收。与对照组和化肥组相比，有机肥处理的抗氧化剂含量最低。研究还发现，有机肥提高了茶树中氨基酸、有机酸和叶绿素的含量。其较低的抗氧化活性和脯氨酸含量使茶树做好了应对或免受胁迫条件影响的准备。事实证明，生物技术开发的有机茶叶堆肥具有这些特性，在茶叶栽培和有机植物生产中大有可为。
