摘要
试验研究了氮肥对柑桔产量及品质的影响,结果表明：氮可提高柑桔产量20.45%~33.73%。适宜的氮用量,并配合磷钾肥,可兼顾柑桔产量和品质。在宜昌地区,金水柑幼年果园适宜的氮磷钾推荐用量为纯N 0.55~0.70 kg/株、P2O50.20 kg/株、K2O 0.5 kg/株,N、P、K比例为1∶0.4∶0.8。
The paper studied the effects of nitrogen fertilizer on oranges＇ output and quality through fertilizer experiment.The results showed that nitrogen could increase the production of citrus 20.45%-33.73%.Suitable nitrogen and phosphorus and potassium would be able to improve output and quality of orange.The recommended dosages of nitrogen, phosphorus and potassium in the young garden of Jinshui orange were as follows ：N 0.55-0.70 kg/plant, P2O5 0.20 kg/plant, K2O 0.5 kg/plant, NPK ratio was 1：0.4：0.8.
