开远藠头长期自产自销,历年种植面积在500亩左右,单产仅500～600公斤,即使根螨严重发生,也未曾引起重视。1982年起市政府组织运销京、津、沪及深圳地区,并出口香港、日本,因质地脆嫩,味美可口,很快畅销东南业市场,成为出口创汇产品,需要迅速扩大种植面积。根螨的危害,严重阻碍了生产的发展,为促进此项经济开发,特对藠头根螨习性进行观察,并研究其防治方法。
The long-term self-production and marketing of the far head, over the years the planting area of about 500 acres, yields only 500 to 600 kg, even if the root mite serious occurrence, it has not attracted attention. Since 1982, the municipal government has been organizing the marketing of Beijing, Tianjin, Shanghai and Shenzhen regions and exported to Hong Kong and Japan. Because of its crisp texture and delicious taste, the municipal government quickly sells the Southeast market and becomes an export-earning product, which requires the rapid expansion of planting area. The harm of root mite severely hindered the development of production. In order to promote this economic development, we specially observed the habit of mite head mites, and studied its control methods.
