摘　　要：以少籽西瓜新品种“长新1号”为试验材料,运用“3414”施肥设计,调查了不同氮磷钾配比对“长新1号”西瓜生长发育的影响。结果表明:处理14(N2P1K1)主蔓长最大,达190.7 cm,功能叶片数也较多,达25片。处理14(N2P1K1)单瓜重最大,达到4.4 kg。因此认为,处理14(N2P1K1)是“长新1号”盆栽西瓜比较合适的施肥水平。In this study,effects of different N,P and K ratios on growth and yield of watermelon‘Changxin No.1’were investigated by using“3414”fertilization design.The results showed that the treatment 14(N2P1K1)has the largest vine and the plant grows to 190.7 cm.The number of functional leaves was more than 25.The fruit weight of treatment 14(N2P1K1)was the largest and the average fruit weight is 4.4kg.Therefore,treatment 14(N2P1K1)is the suitable fertilization level for potted watermelon‘Changxin No.1’.
