Abstract [Objective] The research aimed to improve the quality and yield of Red Globe grape cultivation. [Method]The fruit grain weight, spike weight, soluble solids and Vc content were increased and the titratable acid content was declined compare to CK.The effect of the treatment based on soil application and foliage dressing was better than others.[Result]In the process of determinating total cyanide, the influence of laboratory reagents and operational factors on the determine results were bigger.Operation must be carefully,try one's best to avoid artificial effect.When calibrating a solution,it should be noted titration endpoint, increasing the number of parallel samples, to prevent excessive deviation.In the reagent preparation, try to pay attention to the exact concentration of the reagent. [Conclusion] The study provides the theoretical basis for the fertilizer management of grape.

氨基酸液肥已在生產中得到很大的推广和应用,目前其主要用于防治缺素生理病害和对弱树进行营养的补充,应用到生长正常的果树的研究报道较少[1-3]。青海地区光照充足,昼夜温差大,且气候冷凉、生长季节短等问题均制约了高海拔地区红地球葡萄优质、高产栽培[4]。特别是在高海拔地区葡萄延后栽培条件下,果实的成熟期由于日照时数变短、气温降低、土壤缺水干旱和葡萄自身生长发育规律等条件的影响,出现了葡萄成龄叶片易衰老黄化、幼叶生长发育较缓慢、品质不易提高等问题[5-6]。研究显示葡萄成熟期成龄叶片衰老黄化和幼叶生长发育缓慢使葡萄光合作用下降,从而使有机物质的积累减少,影响了葡萄的品质[7]。笔者以3年生红地球葡萄为试材,在大通县盛天农业生产基地的日光温室内在葡萄不同生长期进行不同处理的氨基酸液肥试验,研究氨基酸液肥不同处理方式对葡萄新稍长度及粗度、葡萄产量与品质的影响,旨在探索出适合青海地区葡萄的氨基酸液肥管理技术,为葡萄肥料管理提供理论依据。……
