- 摘要:
- 春油菜菌核病一般田块发病率为8 %～ 50 %, 重病区可达80 %以上。通过研究多种栽培措施与油菜菌核病发生的关系和药剂防治菌核病的效果, 建立春油菜菌核病综合防治体系。结果表明:合理轮作、垄作、中耕可降低田间菌核数, 选择地势较高的田块种植, 适时晚播、合理密植、施肥,防倒伏和杂草等有利于减轻病害发生。施用50 %农利灵可湿性粉剂的防治效果达到88. 3 %, 施用剂量以1. 5 kg /hm2 最为经济有效, 盛花期和终花期喷施效果最佳。
- Abstract:
- The result s o f the study show ed :the di sease rate w as 8 %～ 50 % generally , in serio usarea it could reach more than 80 %. To cont ro l the di sease , w e should take the methods as fo llows :Reasonable rotation , ridge culture and cultiv ation to reduce the number of the sclerotinia ;Planting on the hig her f ields , reasonable clo se plant ing and using of fer tilizer to prevent lodg e ;Co ntro l w eeds and planting latterly. The 50 % Ro nilan (WP) w as the best for chemical cont ro land the cont rol effect could reach 89 %, the ef ficient and economical do se w as 1. 5Kg /hm2 , the besttime w as at the peak of f lo rescence and the end o f flo rescence.
