- 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N2 P2 K2（尿素0.45 kg+钙镁磷肥1.72 kg+氯化钾0.35 kg）+牛粪50 kg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25.1 kg，比对照增产14.5 kg。折算后的基肥施用量为株施牛粪50 kg+复合肥14 kg。
- Abstract:
- Taking ‘Taicheng No4’ 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 N2P2K2(Urea 0.45 kg+Calcium magnesium phosphate 1.72 kg+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 fruitsetting 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+1.4 kg compound fertilizer for each plant.
