大棚蔬菜生产就要来到,近年来,随着保护地生产面积不断增加,设施农业高密度栽培及在同一块土地上连年种植一种作物,均有利于土传病害病原菌、根结线虫及地下害虫的积累、生长和繁殖。据研究发现:各种蔬菜90%以上的真菌病害的病源菌及细菌都是土壤传播的。如果对这些病虫害防治措施不对路,将严重影响蔬菜的产量和质量。根据近几年的实践经验其主要防治措施如下:一、土传病菌的预防除彻底清理大棚物理防治法外,主要是采用高效低毒低残留药剂进行防治。方法有:药剂消毒:1、喷淋或浇灌法:将
Greenhouse vegetable production is coming. In recent years, with the increasing production area of protected areas, high-density cultivation of agricultural facilities and the cultivation of a crop in the same land year after year are conducive to soil-borne disease pathogens, root-knot nematodes and underground Pest accumulation, growth and reproduction. According to the study found that: more than 90% of all kinds of vegetables, fungal diseases, pathogenic bacteria and bacteria are soil-borne. If these pest control measures are not on the road, will seriously affect the yield and quality of vegetables. According to the practical experience in recent years, the main prevention and treatment measures are as follows: I. Prevention of Soil-borne Bacteria In addition to thoroughly cleaning the physical control of greenhouse law, it is mainly the prevention and treatment of pesticides with high efficiency, low toxicity and low residue. Methods: Disinfection agent: 1, spray or water law: will
