摘　　要：为了更好地利用化学诱抗剂缓解盐分障碍以提高西瓜产量和品质,采用大棚小区随机区组法,以西瓜品种京欣1号为试验材料,研究水杨酸对盐胁迫下西瓜产量和品质的影响。结果表明:水杨酸的处理浓度为1mmol·L-1时,小区平均产量、可溶性蛋白、可溶性总糖、维生素C含量最高,并且西瓜果实的总酸度含量呈现出不同的变化趋势。说明抗逆诱导物质提高了西瓜产量,改变了西瓜果实的可溶性蛋白、可溶性总糖、总酸度的含量和糖酸比,从而改善了西瓜的品质。In order to use the chemical induced resistant agent to alleviate the obstacle,improve the yield and quality of watermelon,greenhouses plot randomized block method was adopted. Taking the watermelon variety Jingxin 1 as test materials,the effect of salicylic acid on yield and quality of watermelon under salt stess was studied. The results showed that when the concentration of salicylic acid was 1 mmol·L-1 , the district average yield, soluble protein, soluble sugar and content of vitamin C were the highest,total acidity content of watermelon fruit showed different trends. It showed that resilience inducing substance improved the yield of watermelon and changed the fruit soluble protein and total soluble sugars, total acidity content and sugar-acid ratio, thereby improve the watermelon quality.
