摘要(Abstract)：

【目的】探究海藻酸水溶肥对梨生长发育的影响,为当地梨产业合理施肥提供理论依据。【方法】以‘黄金’梨和‘酥梨’为试验材料,用常规施肥[NPK(C)]、传统水溶肥[NPK(F)]、等量NPK海藻酸水溶肥[NPK(HF)]、NPK用量减施25%海藻酸水溶肥[3/4NPK(HF)]和NPK用量减施50%海藻酸水溶肥[1/2NPK(HF)]处理梨树,测定比较处理间果实产量、品质、养分吸收和经济效益等指标。【结果】与NPK(C)和NPK(F)处理相比‘,黄金’梨园区的3/4NPK(HF)处理提高果实糖酸比和叶片氮养分含量,显著降低果实石细胞含量,且各指标基本上高于NPK(HF)和1/2NPK(HF)处理。在‘酥梨’园区,3/4 NPK(HF)处理梨可溶性糖和叶片氮养分含量较NPK(F)处理分别显著提高12.38%和9.08%。同时,海藻酸水溶肥减量使用明显增加园区经济收益。【结论】在两梨园当前施肥量下,减施25%的海藻酸水溶肥处理不会导致梨显著减产和果实品质降低,其综合效果优于其他处理。
