摘　　要：为了解江苏沿海地区不同钾肥运筹对西瓜生长和品质的影响,以‘早佳（8424）’为试验品种,钾肥分别作基肥、第1次膨大肥、第2次膨大肥3次施用,设计5个不同配比的钾肥运筹试验。结果表明：施钾肥对西瓜生长有明显的促进作用,能控制西瓜营养生长,促进生殖生长;大棚西瓜栽培中,如果收获1茬西瓜,钾肥运筹以基肥、膨大肥各半最好;如果收获2茬西瓜,钾肥运筹以基肥20%~30%,第1、第2次膨大肥各30%~40%最好。In order to clarify the effect of different potash fertilizer management on watermelon growth and quality in the coastal areas of Jiangsu, potash fertilizer management experiment was conducted with five different ratio by using the variety of ＇Zaojia 8424＇. The potash fertilizer was split to apply for three times as basal fertilizer, the first expansion fertilizer and the second expansion fertilizer. The resuhs showed that the vegetative growth was controlled and reproductive growth was promoted of watermelon under potassium fertilizer app｜ication. In greenhouse, if only crop once ,it is optimal to applying the potash fertilizer as basal fertilizer and expansion fertilizer each half, if crop twice, the application of potash fertilizer should be 20%-30% as basal fertilizer, 30%-40% as the first and second, expansion fertilizer respectively.
