摘要
草莓在同一地块长期连作,会造成病虫害的滋生和蔓延、土壤理化性质、根际微生物群的恶化、自毒现象。使草莓易感染黄萎病、线虫病、根腐病及凋萎病等多种土传病害。通过对连作障碍发生机理的研究分析,从而探讨出土传病害是造成重茬病害的主要因子,以根腐病危害最广泛、最严重。介绍其危害较严重的种类,从而为综合防治奠定基础,提出以农艺、物理、化学、生物的综合防治配套技术。
Fragaria ananassa replant many times at a same area, create bug and arbo malady, worsen about physical and chemistry character of soil, worsen about germ group of root entourage, and poisoning itself. Fragaria ananassa replant affect easily many bug malady of soil,example blight,nematode malady, root rot and sear malady. The article research analysis on occur theory of replant failure, the main reason of replant bug malady is bug malady of soil infection, the most broad and severe bug is root rot. Introduce style, symptom and occur condition, for integration control establish basis, introduce controlling methods of agriculture, physical, chemistry and being.
