摘　　要：为探索茶园科学施肥技术,2022年在酉阳自治县茶园开展了化肥减施配施有机肥对春茶产量、品质和经济效益影响的田间对比试验。结果表明,与农民习惯施肥相比,优化施肥模式在化肥减施78.6%的情况下,明显提高芽叶密度,春茶产量增加16.5%;提高了新梢游离氨基酸总量、降低了酚氨比,特别是对中期春茶的增产提质作用明显;节本增收2.37万元/hm2,经济效益十分显著;“有机肥+茶树专用复合肥”模式优势明显,值得推广应用。In order to explore scientific fertilization techniques in tea gardens,field comparative trials with different fertilization modes were carried out in YouyangAutonomous County in 2022.Their effects on yield,quality component and economic benefits of spring tea were studied.The results show that shoot density were significantly increased,and the spring tea yield was increased by 16.5%under the optimized fertilization mode,compared with the farmers'customary fertilization.The total amount of free amino acids in spring shoots was increased and the phenol-ammonia ratio was decreased,especially in the middle stage of spring tea.The cost saving and income increase reached 23700 yuan/hm2,resulting in significant economic benefits.The model of"organic manure+special compound fertilizer"has obvious advantages and is worth promoting and applying.
