摘要
为提高套袋苹果果面红、黑点病的防治效果,进行了综合防治试验。主要采取加强栽培管理、增施有机肥、提高土壤中有效态钙的含量、改善树体通风透光条件、选用无静电膜袋、适时套袋、雨后及时调节袋内湿度和套袋前后致病菌的化学防治为一体的综合措施,使病果率平均控制在5%以下,横径≥75mm的好果率达92%以上,果品平均售价提高83 1%。
To control the red and black scars on the surface of the apples by using plasfic film bags is to take the following comprehensive measures:strengthening the planting management,adding more fertilizer,increasing Ca in soil,improving the condition of wind and sun light between the trees,selecting non -static electricity plastic film bags,bagging in time,adjusting humidity in bags and bacterium from.
