【摘要】 为有效防控西瓜、甜瓜细菌性果斑病,用杀菌剂1号处理西瓜、甜瓜种子,采用嫁接育苗以及田间试验评价的方式,测定了西瓜、甜瓜嫁接苗果斑病的发生率、田间产量等指标。结果表明,使用杀菌剂1号处理的种子,后期未发现细菌性果斑病的发生,西瓜、甜瓜幼苗在发病率、减少用药量、产量等方面均优于常规技术种子消毒处理对照组。可见,杀菌剂1号可有效防控果斑病的发生,对西瓜、甜瓜嫁接苗的生产、减少农药用量具有良好的促进作用。更多还原

【Abstract】 In order to effectively prevent and control the incidence of bacterial fruit spot disease in watermelon and melon,watermelon and melon seeds were treated with fungicide No.l,grafting seedlings and field test evaluation was used to measure indexes including the incidence of fruit spot disease and field output of grafted seedlings and so on.The results showed that the seeds treated with fungicide No.l had no bacterial fruit spot disease in the later stage,watermelon and melon seedlings were better than the control(seed disinfection with conventional technique) in terms of morbidity,reduction in dosage and yield.It can be seen that the fungicide No.l can effectively prevent and control the occurrence of fruit spot disease,and has a good promotion effect on the production of watermelon and melon grafted seedlings and reducing the amount of pesticides.更多还原
