山西省梨树休眠期病虫害化学防治技术的提出与推广应用

Propose and Popularize the Technology of Chemical Control of Diseases and Insect Pests in Dormant Period of Pear Tree in Shanxi Province

休眠期是梨树全年生育期中至关重要的一环,抓好这个时期病虫害的防治措施,将使梨树全年生育期中病虫的危害降低60%左右。但是梨农在休眠期滥用农药现象严重,而且随意增加农药使用次数和用量,造成果品农残超标、品质降低、环境污染,农药有效利用率仅33%左右。2018年—2019年,梨树休眠期病虫害化学防治技术在山西省临汾市隰县进行了推广实施。在实际生产中取得了显著效果。示范区病虫害发生和危害减少20%以上,梨农增收效果明显增加,取得了良好的经济效益。该项技术为保障食品安全生产、提高果品质量、增加果农收入、促进梨产业的健康发展提供了强有力的技术支撑。

The dormancy period is an important part of the whole growth period of pear trees.The control measures of diseases and insect pests in this period will reduce the damage of diseases and insect pests by about 60%during the whole growing period of pear tree.However,the abuse of pesticides by pear farmers during dormancy period is serious,and the number and amount of pesticides used are increased at will,which results in excessive residue,low quality and environmental pollution,and the effective utilization rate of pesticides is only 33 About%.In 2018-2019,the chemical control technology of diseases and insect pests in the dormancy period of pear tree was popularized and implemented in Xixian County,Linfen City,Shanxi Province.achieved remarkable results in actual production.The occurrence and harm of diseases and insect pests in demonstration area are reduced by more than 20%,and the effect of increasing income of pear farmers is obviously increased,and good economic benefits have been obtained.This technology provides strong technical support for ensuring food safety production,improving fruit quality,increasing fruit farmers'income and promoting the healthy development of pear industry.
