设施小型西瓜病虫害发生特点及绿色防控技术

Characteristics of Pest and Disease Occurrence and Green Control Technologies for Facility-Grown Small Watermelon

摘要: 全文系统总结了北京市大兴区设施小型西瓜在不同生育期的主要病虫害发生特点及其成因。在此基础上，文章详细阐述了一套以绿色防控为核心的综合治理技术体系。该体系覆盖了生产全过程，包括生产前的无病虫壮苗培育、棚室与土壤消毒，生产中的物理防治、生物防治、合理的化学防治以及授粉昆虫的应用，以及生产后的植株残体无害化处理。文章旨在为大兴区西瓜产业的可持续发展提供一套实用的技术操作指南。

Abstract: This paper systematically summarizes the occurrence characteristics and underlying causes of major pests and diseases in facility-grown mini watermelons in Daxing District, Beijing, across different growth stages. Building upon this, the article elaborates on a comprehensive management technology system centered on green prevention and control. This system covers the entire production process, including: pre-production cultivation of disease- and pest-free robust seedlings, and disinfection of greenhouses and soil; in-production physical and biological control, rational chemical control, and the application of pollinating insects; and post-production harmless treatment of plant residues. The aim of this article is to provide a practical technical guide for the sustainable development of the watermelon industry in Daxing District.
