设施西瓜生产土传病害绿色防控技术

土壤是一个相对复杂、富于动态变化的有机结合体,正常情况下土壤微生物之间处于动态平衡状态,然而多年以来因连续种植单一作物导致重茬生产,加上施肥、用药等不良管理等因素,致使土传病害的发生机率越来越严重。土传病害作为设施西瓜栽培中顽固性病害,严重制约着设施西瓜的绿色优质高效生产。系统分析了设施西瓜土传病害的类型与诊断,从轮作、棚室消毒、种子处理、育苗基质选用、嫁接应用、定植时处理及健身栽培等方面对设施西瓜土传病害综合防控技术进行系统集成,进而为设施西瓜生产中土传病害的绿色防控技术提供帮助,推动设施西瓜产业可持续性发展。

Green prevention and control technology of soil bornediseases in protected watermelon production

s: Soil is a complex and dynamic organic whole. Under normal circumstances, soil microorganisms are in dynamic balance. However, for many years, the occurrence of soil borne diseases has become more and more serious due to continuous cropping, continuous cropping and improper field management. As a stubborn disease in protected watermelon cultivation, soil borne diseases seriously restrict the green, high-quality and efficient production of protected watermelon. This paper systematically analyzes the types and diagnosis of soil borne diseases of protected watermelon, and systematically integrates the comprehensive prevention and control technology of soil borne diseases of protected watermelon from the aspects of rotation, shed disinfection, seed treatment, seedling substrate selection, grafting application, treatment during planting and fitness cultivation, in order to provide reference for the green prevention and control of soil borne diseases of protected watermelon, Promote the healthy development of facility watermelon industry.
