为了研究腐植酸有机液肥对柑橘产量的影响,分析了喷施3次不同配方腐植酸有机液肥后广东肇庆“皇帝贡柑”单株果实重量、果实横径和亩产量。结果表明,与对照相比,喷施液肥后广东肇庆“皇帝贡柑”果实横径增加3.94%~11.28%,单株果重增加幅度为1.89%~11.50%,增产幅度为1.86%~11.50%,比对照增收222.60~2616.78元,增收幅度为0.90%~10.53%,喷施2号腐植酸有机液肥增产增收效果最为显著。
In order to study the effect of humic acid organic liquid fertilizer on the yield of citrus, the fruit weight, fruit diameter and yield per plant of Zhaoqing “Emperor Gonggong ” were analyzed after spraying 3 times different formulations of humic acid organic liquid fertilizer. The results showed that compared with the control, the fruit diameter of Zhaoqing “emperor Gonggong ” increased by 3.94% ~ 11.28%, the fruit weight per plant increased by 1.89% ~ 11.50% and the yield increased by 1.86% 11.50%, 222.60 ~ 2616.78 yuan more than the control income, the rate of increase of 0.90% ~ 10.53%, spraying 2 humic acid organic liquid fertilizer yield and income the most significant effect.
