| 摘 要： | 为探索西瓜的适宜施肥量和养分配比, 通过田间试验, 研究了不同肥料用量和配比对西瓜产量、品质及养分吸收的影响。结果显示: 与习惯施肥处理相比, 减氮磷钾处理的西瓜产量、Vc含量分别增加0.77%、17.18%, 还原糖含量、硝酸盐含量分别减少12.56%、27.94%; N、P2O5、K2O养分总量相同、比例不同的3个处理间相比, 减氮磷增钾处理的西瓜产量、Vc含量、还原糖含量均最高, 硝酸盐含量最低; 习惯施肥、减氮 磷钾、减氮磷、减氮磷增钾4个处理的西瓜秧中N、P2O5、K2O含量比例分别为: 1︰0.18︰2.26、1︰0.22︰2.66、1︰0.26︰2.75、1︰0.19︰2.46; 西瓜皮中N、P2O5、K2O含量比例分别为: 1︰0.34︰2.78、1︰0.34︰2.60、 1︰0.30︰2.37、1︰0.29︰2.14。综合考虑各项指标, 在本试验条件下, 施肥总量比习惯施肥量减少36%、N︰P2O5︰K2O为1︰0.41︰1.28是西瓜最优施肥处理。
