| 摘 要： | 为促进冬瓜平衡施肥，以田间试验方法研究冬瓜对氮、磷、钾、镁、锌五种营养元素效应，试验表明氮、钾、镁对冬瓜产量有显著的影响，与OPT处理相比，OPT-N、 OPT-K 、OPT-Mg处理分别减产25.9 ％、18.6 ％和16.7 %。施肥对冬瓜品质有显著影响，缺钾、缺磷和缺锌显著降低了冬瓜水溶性糖含量。施肥影响到冬瓜叶片、茎蔓和果实对营养成分的吸收。本试验OPT处理的N、P2O5、K2O、MgO肥料利用率分别为21.53 %、8.21 %、35.50 %和20.2 %。每形成1000公斤冬瓜果实吸收1.40公斤的N，0.51公斤的P2O5，2.49 公斤的K2O和0.33公斤的MgO，冬瓜吸收NPKMg的比例约为1：0.36：1.78：0.24。

| Abstract: | A field experiment was conducted in Hainan area to examine the effects of balanced fertilization with N,P,K,Mg and Zn on wax gourd yields,fruit quality,nutrient content and nutrient uptake by plant. The results showed that fruit yields were significantly influenced by N,K and Mg fertilizers,differently,application of P and Zn had no effect on fruit production. Yields decreased by 25.9%,18.6% and 16.7% with minus N,K or Mg treatment,respectively. Fruit qualities were favored by balanced fertilization. Minus K,P,or Zn treatment reduced soluble sugar. Balanced fertilization also increased nutrient content in plant leaves and stalks,meanwhile improved nutrient uptake by plant,and thus,the N,P2O5,K2O,MgO use efficiency was 21.53%,8.21%,35.50% and 20.2%,respectively,and absorbed nutrient with 1000 kg fruit of wax gourd of N,P2O5,K2O,MgO were 1.40 kg,0.51 kg,2.49 kg and 0.33 kg. The absorption ratio of N,P,K and Mg was 1：0.36：1.78：0.24. |
