摘要
为科学评估病虫害对水稻生产的影响程度和植保措施对防灾减灾的重要作用,2022年度湖南省植保植检站组织衡南等6个县(市、区)开展了水稻病虫害防控植保贡献率评价试验,通过加权平均测算和综合分析,结果表明病虫防控(不包括草害和鼠害)对水稻总产的贡献率为23.80%。据此测算,2022年湖南全省通过病虫防控共挽回稻谷损失近62.8亿kg。
To scientifically evaluate the impact of diseases and pests on rice production and the important role of plant protection measures in disaster prevention and reduction,in 2022,Hunan Plant Protection and Plant Quarantine Station organized an evaluation on the contribution rate of rice diseases and pests control and plant protection in six counties and cities such as Hengnan county.Through weighted average calculation and comprehensive analysis,the results showed that the contribution rate of disease and insect pest control(excluding grass and rodent damage)to the total yield of rice was 23.8%.According to this calculation,Hunan province saved nearly 6.28 billion kg of rice losses through disease and insect pest control in 2022.
