摘要
为了科学评估植保技术措施对防灾减灾的重要作用,2023年度湖北省植物保护总站在荆州区、仙桃市、宜城市、随县、安陆市等地开展了小麦病虫害防控植保贡献率评价试验.通过采用多点试验测产,结果表明:2023年湖北省小麦病虫害防控成效显著,严格科学防控区、统防统治区、农民自防区的植保贡献率分别为31.48％、25.79％、18.98％,其中严格科学防控区比农民自防区的植保贡献率高12.5百分点,统防统治区比农民自防区的植保贡献率高6.81百分点.如果在完全不防治的情况下,全省小麦病虫害造成的损失率将达31.48％.选择5个试验县的结果,经科学评估,湖北小麦病虫害防控植保贡献率为22.56％;根据湖北小麦实际总产量,以此测算,2023年湖北省小麦病虫害防控挽回粮食损失10.21亿kg.
Abstract
To evaluate the important role of plant protection measures in disaster prevention and mitigation scientifically,Hubei Plant Protection Station carried out evaluation of the contribution rate of wheat disease and pest management in Jingzhou district,Xiantao city,Yicheng city,Suixian county and Anlu city in 2023.Multi-point test showed that significant control effects on wheat diseases and pests were observed in Hubei province in 2023,with the contribution rates of 31.48％,25.79％and 18.98％in scientific and strict control areas,integrated control areas and farmers'self-control areas,respectively.Scientific and strict control areas and integrated control areas were 12.5 and 6.81 percentage points higher than that of farmers'self-control areas,respectively.Wheat yield loss caused by the diseases and pests in Hubei province was estimated to reach 31.48％without control.Based on the results from the five test counties,scientific assessment indicated that the contribution rate of plant protection against wheat diseases and pests in Hubei province was 22.56％.According to the actual total output,it was estimated that controlling wheat diseases and insects saved 1.021 billion kg grain in Hubei province in 2023.
