摘　　要：研究基肥用量对秀芳西瓜生育动态与营养代谢的影响。结果表明,在一定氮、磷、钾水平下,增施氮、磷、钾肥,秀芳产量反而降低;在氮、磷肥水平相同条件下,增施有机肥和钾肥,秀芳生长速率快,叶绿素含量高,果个大,产量高,品质明显提高;在氮肥水平相同条件下,增施磷肥比增施钾肥增产。The effects of pre-plant fertilizer application on growth, nutrition metabolism and yield of Xiufang watermelon were studied. The results showed that the yield was reduced with increase of N ,P and K fertilizer above the common N ,P and K fertilizer levels. When organic fertilizer and K fertilizer were increased under the condition of same N and P fertilizer level, watermelon plants showed rapid growth, higher content of chlorophyll, higher yield and better quality. Under the same N fertilizer level, the yield was much higher with application of P fertilizer than K fertilizer.
