摘要
近年来,一些次要病虫害的发生给豫南稻区再生稻生产造成了严重威胁。豫南稻区再生稻主要病虫害发生种类为“三病三虫”,即立枯病、纹枯病、稻瘟病、稻水象甲、二化螟、稻纵卷叶螟,各县区均有不同程度发生,特别是立枯病已成为制约豫南稻区再生稻发展的主要障碍,其他如大螟、稻飞虱、恶苗病、稻曲病等病虫害发生程度极轻或基本不发生。结合理论与实践提出了强化农业防治、重视物理防治、加强生物防治、利用化学防治的绿色综合防控建议,以期为再生稻的生产提供技术支撑。
In recent years,the secondary diseases and pests has caused serious threats to ratooning rice in southern Henan Province.In the paper,the occurrence regularity of major diseases and pests of ratooning rice in southern Henan Province was summarized including rice seedling blight,rice sheath blight,rice blast,lissorhoptrus oryzophilus,chilo supperssalis walker and cnaphalocrocis medinalis guenee.Each county or district has varying degrees of occurrence.Especially rice seedling blight has become the main obstacle restricting the development of ratooning rice in southern Henan Province.The occurrence degree is extremely mild or almost non-existent in sesamia inferens walker,rice planthopper,fusarium fujikuroi Nirenberg and rice false smut.The comprehensive green prevention and control measures were proposed to strengthen agricultural control,attache importance to physical control,strengthen biological control and use chemical control,in order to provide technical support for ratooning rice in southern Henan Province.
