摘要
1987～1990年研究结果表明,在实施控害丰产栽培配套技术、抑制稻飞虱、纹枯病发生的基础上,在水稻孕穗期按复合防治指标,应用高效长效安全的新药剂扑虱灵与井岗霉素混合防治一次的综合防治模式,能控制其病虫危害.与常规防治相比,施药次数减少1～2次,每公顷产量增加525.0kg,增收375.0元,提高效益10%左右.生态环境进一步改善.
When we carried out a set of high yield cultivating technique in 1987-1990 under pest and disease controlled environment to inhibit the occurence of planthopper and sheath blight in rice, an integrated control model was applied with Jingan-mycin and buproferin, the high, long effect and safety fungicide and insectcide at spike formation stage according to the multiple-species economic threshold. The result indicated that this model could control both of the pest and disease. When compared to the conventional control, it could decrease the 1-2 times of chemicals supply with this method and increase yield by 525.0kg/hm2, which was equal to 375 yuan or raised benefit by 10%. And the ecological environments were further improved.
