摘　　要：为研究抗坏血酸在草莓上的应用效果,开展田间研究试验。结果表明,草莓全生育期使用6%抗坏血酸水剂,植株抗逆能力增强,畸形果率降低了5.6%以上,有效提高植株移栽成活率。6%抗坏血酸水剂对白粉病、灰霉病的防效分别为54.5%、59.7%,其单果重较清水对照单果增重12.5g。抗坏血酸与杀菌剂混用具有协同增效作用。In order to study the application effect of ascorbic acid in strawberry,ascorbic acid 6%WA was sprayed on strawberries from transplanting to first season fruit maturity.The results showed that plant adverse resistance was increased,the rate of fruit malformation was reduced by more than 5.6%and the survival rate of plant transplanting was effectively increased during the strawberry whole growth period.The control effects on powdery mildew and gray mildew were 54.5%and 59.7%,respectively,and the average single fruit weight increased by 12.5 g compared with the control treatment.Ascorbic acid 6%WA mixed with fungicides had synergistic effects on increasing yield and controlling powdery mildew and gray mildew production on a large scale.
