1994～1996年研究了稻田13种可控因素对水稻病虫害、天敌和产量的综合效应以及分期混合施药技术。根据既控制病虫增产又保护生态的原则，综合评价了可控因素，提出了水稻病虫害系统最优控制为中国91或辐4-2，N 150kg/hm2，底肥：分蘖肥：穗肥N分配比为80∶0∶20，P2O5 75kg/hm2，K2O 240kg/hm2，ZnSO4 15kg/hm2，插秧期春季稻和夏季稻分别4月30日和6月15日前后,种植密度为36万墩/hm2，水管理为适时标准烤田，播种期甲基异柳磷0.08%与多菌灵0.15%混合浸种防治地下害虫和恶苗病,分蘖初期(7月25日前后)杀虫双750g/hm2与井冈霉素150g/hm2×2混合喷雾防治二代稻纵卷叶螟和纹枯病，分蘖后期(8月20日前后)捕虱灵75g/hm2与三环唑300g/hm2混合喷雾防治稻飞虱和稻瘟病。

The integrative effect of 13 controllable factors of rice fields on diseases and insect pests, natural enemies and rice yield, and technology of mixture of insecticides and fungicides to control main diseases and insect pests of rice at three periods were studied from 1994 to 1996. We intended to act on the criterion of not only good result of control to the pests and increase of rice yield but also protection of natural enemies, the 13 controllable factors were evaluated synthetically and the optimum system control to the diseases and insect pests of rice was suggested as follows:1) Cultivar China 91 or radiation4-2.2) Dosages of fertilizer N, P2O5, K2O and ZnSO4 application at 150kg/hm2, 75kg/hm2, 240kg/hm2 and 15kg/hm2 respectively.3) Ratio of N at 80∶0∶20 at before transplanting seedling, branching stage and ear stage.4) Time of transplanting seedling of spring and summer rice on about 30, April and 15 June.5) Rice density at 360000 clumps/hm2.6) Standard roasted field. 7)Control soil insects and Fusarium fujikuroi Sawada by mixture soaking seeds with isofenphos-methyl and carbendazim at 0.08% and 0.15% of seed weight respectively.8) Control the second generation of rice leaf folder and sheath and culm blight of rice by mixture foliage spraying with shachong shuang and Jinggang antibiotic at 750g/hm2 and 150g/hm2 respectively on about 25 July. 9) Control rice planthoppers and rice blast by mixture foliage spraying with buprofezin and tricyclazole at 75g/hm2 and 300g/hm2 respectively on about 20 August.
