在植保工作中,“重虫轻病”现象十分普遍。人们习惯于没看到病害发生,就不进行病害防治,导致病原物积累,病害一旦发生常造成不可收拾的局面。在植物最重要的生长介质——土壤中,这一现象尤为严重。土壤微生态系统失衡,土传病害加重、根结线虫为害猖獗,常常导致植物死苗、烂根、死株、凋萎、早衰等现象。
In the work of plant protection, the phenomenon of “pest insects” is very common. People are accustomed to not seeing the occurrence of the disease and not carrying out the disease prevention and control, resulting in the accumulation of pathogens and the frequent occurrence of disease once caused by the disease. This phenomenon is particularly severe in soil, the plant’s most important growth medium. Soil microbial ecosystem imbalance, soil-borne diseases aggravate, root-knot nematode damage rampant, often leading to plant dead seedlings, rotten roots, dead strains, wilting, premature aging and so on.
