On Influence of Different Percentage of N,P,K and Ca on Navel Orange Yield and Fruit Quality

摘要: 通过选用大量元素氮（N）、磷（P）、钾（K）和中量元素钙（Ca）肥相结合的肥料组合方式，采用4因素3水平正交施肥试验，探索了不同N，P，K，Ca水平对脐橙产量、品质等的影响．结果表明：在本试验条件下，在每667m2施N肥20kg，同时配施适量的P，K，Ca肥的情况下，既能提高产量，也能使果实风味和品质得到提高．其中产量以处理4（N2P1K2Ca3）水平为最高，两年累积每667m2达3478.0kg以上，果实品质以处理5（N2P2K3Ca1）水平最好，风味浓郁，香甜，化渣，其TSS和WSS都最高，分别高达13.98和14.84，其糖酸比和固酸比分别达18.06和17.01．在一定范围内，不同肥料对产量的相关性从大到小依次为N，K，Ca，P，且都呈正相关，其中N肥与产量呈显著正相关．K肥与TSS和固酸比也表现为显著正相关关系．综合各种因素，以处理5施肥方案为最优方案．
