1 材料与方法 1996～1997年,选择建棚时间、结构、栽培管理水平一致且连作番茄、甜椒同一品种2年以上的2个大棚进行处理,以不处理作对照。在大棚苗定植前10d,用50%多菌灵可湿性粉剂(江苏新沂农药厂生产)按每6g/m~2均匀撒在畦表面,然后翻入土内。番茄棚棚壁及立柱等用200倍5%菌毒清(山东北方制药厂生产)均匀消毒,甜椒棚则用500倍高锰酸钾液消毒,然后大棚盖膜密闭薰蒸7d,晾棚3d,进行定植。定植后每10d定株调查一次病害发生情况,计算防效、产量至第一穗果采收结
1 Materials and Methods From 1996 to 1997, we chose to build a greenhouse with the same level of time, structure and cultivation and management. The two kinds of greenhouse with the same variety of tomato and sweet pepper more than two years were treated with no treatment as the control. In the greenhouse seedlings 10d before planting, with 50% carbendazim WP (Jiangsu Xinyi Pesticide Factory) per 6g / m ~ 2 evenly sprinkled on the surface, and then turned into the soil. Tomato shed shed walls and columns 200 times 5% Mycophenolate (Shandong North Pharmaceutical Factory production) uniform disinfection, the sweet pepper shed 500 times with potassium permanganate disinfection, and then covered with plastic greenhouse fumigation 7d, Hangpen 3d, planting. Planting 10d after planting a disease survey, the calculation of anti-efficiency, yield to the first ear harvest node
