Abstract
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.关键词
