现代农业中,广泛地交换作物品种种质资源与成功地防止作物危险性病虫传播同等重要。因此,在作物种资源交换中采取一种综合性的检疫措施,达到既防止作物危险性病虫传播,又使种苗调运畅通之目的,就显得格外重要。六十年代以来,陕西省汉中地区把产地检疫措施应用于作物种苗的生产实践,取得了显著效果。据1981年统计,通过连年产地检疫,有效地控制了水稻白叶枯病的蔓延和为害,发病面积从1973年的14.1万亩压缩到2000余亩,每年为生产提供无病良种200多
In modern agriculture, extensive exchange of germplasm resources for crop varieties is as important as the successful prevention of the spread of pest and disease in crops. Therefore, in the exchange of crop resources to take a comprehensive quarantine measures to achieve both prevent the spread of pests and diseases of crops, but also make the seedlings dispatched smooth flow of purpose, it is particularly important. Since the 1960s, the Hanzhong area in Shaanxi Province has applied the quarantine measures of origin to the production of crop seedlings and achieved remarkable results. According to the statistics of 1981, through the quarantine year after year, the spread and damage of rice bacterial leaf blight were effectively controlled. The area of disease was reduced from 141,000 mu in 1973 to more than 2,000 mu. More than 200 non-diseased seeds were produced annually for production
