摘　　要：以"太城4号"枇杷为试材,采用"3414"肥料效应田间试验,研究了氮磷钾不同基肥水平对枇杷结果母枝的影响。结果表明:以株施肥处理N2P2K2(尿素0.45kg+钙镁磷肥1.72kg+氯化钾0.35kg)+牛粪50kg的综合效果最佳,对中心花枝、侧生花枝、采果痕枝花枝3类结果母枝的茎粗、叶片数、成花枝率、坐果花枝率等均显著高于对照,单株产量25.1kg,比对照增产14.5kg。折算后的基肥施用量为株施牛粪50kg+复合肥1.4kg。Taking ＇Taicheng No. 4 loquat as material, the effects of different levels of N-P-K base fertilizers on loquat flowering branches were studied with ＇3414 fertilizer field test. The results showed that application of fertilizer per plant of NzPzKz （Urea 0. 45 kg-＋-Calcium magnesium phosphate 1. 72 kg-I-Potassium chloride 0. 35 kg）＋50 kg of cow dung had the best effect ,with larger stem diameter, more leaves, higher rates of flowering branches and fruit-setting branches no matter of centre flowering branches, lateral flowering branches or picking mark flowering branches compared to the control. Specifically,the yield of single plant was 25. 1 kg, which was 14. 5 kg higher than that of the control. The application level of base fertilizer was equivalent to 50 kg cow dung＋l. 4 kg compound fertilizer for each plant.
