人参病害的综合防治是发展人参生产,保证优质高产的主要措施。几十年的科研、生产实践证明,采取单一措施防治病害是达不到理想效果的。病害的发生与环境条件关系密切,发病程度受温度、空气湿度、水分、肥力、土壤、空气等生态条件影响很大,因此必须因地、因时、因病的运用农业、化学、生物等防治方法,把病害控制在经济允许的最低水平下,并与丰产栽培结合起来,达到降低病害提高保苗率,优质高产的目的,现将综合防治方
The comprehensive prevention and treatment of ginseng diseases is the main measure to develop ginseng production and ensure high quality and high yield. Decades of research, production practice has proved that to take a single measure to prevent disease is not up to the desired effect. The occurrence of diseases is closely related to the environmental conditions. The incidence of diseases is greatly affected by the ecological conditions such as temperature, air humidity, soil moisture and soil, air and so on. Therefore, it is necessary to prevent and control the disease by the use of agriculture, chemistry and biology Method, the disease control in the economy to allow the lowest level, and with high yield cultivation combine to reduce the disease to improve the seedling rate, high-quality and high yield purposes, now comprehensive prevention and treatment side
