近年来,我国从国外新引进和国内调运种子苗木的数量增加较快。据统计,1994年全国省间调运种子147481万公斤,苗木60453万株;从国外引进种苗6000多批次,其中种子367万公斤,苗木69万株。由于实施检疫,有效防止了许多危险性病虫害的传播蔓延。但是,在新形势下,植物检疫工作的任务相当繁重,一些检疫对象还是通过种种途径传入了国内。如1985年福建漳州从菲律宾引进的香蕉苗中带入了我国没有发生分布的香蕉穿孔线虫,后经三年多的严格的封锁扑灭措施才予以根除;1988年水稻上的重要检疫害虫稻水象甲首次在我国河北唐海县的水稻上发生危害,近年发生范围逐年扩大,严重危胁我国的水稻生产安全。这些充分说明,农业是国民经济的基础产业,是自然风险较大的弱质产业,需要对其加以特殊的保护。强化植物检疫措施,保障种苗安全生产和流通,就是对农业实施保护的强有力的保障措施之一。
In recent years, China newly introduced and domestic deployment of seed seedlings increased rapidly. According to statistics, in 1994, there were 1.47481 million kilograms of seedlings transported and transplanted across the country, with 604.53 million seedlings. More than 6,000 batches of seedlings were introduced from abroad, of which 3.67 million were seeds and 690,000 seedlings. As a result of the implementation of quarantine, effectively prevent the spread of many dangerous pests. However, in the new situation, the task of phytosanitary work is quite heavy, and some quarantine objects are still imported into China through various channels. For example, in 1985, the banana seedlings introduced from the Philippines in Zhangzhou, Fujian Province brought banana perforation nematodes that did not occur in our country and were eradicated only after more than three years of rigorous blockade and suppression measures. In 1988, the important quarantine pest rice water A for the first time in China’s Hebei Province, Tanghai County, rice on the occurrence of harm, in recent years the scope of the expansion has expanded each year, a serious threat to our country’s rice production safety. All these fully show that agriculture is the basic industry of the national economy and a weak-natured industry with a high natural risk and needs special protection. Strengthening phytosanitary measures to ensure the safe production and circulation of seedlings is one of the powerful safeguards for the protection of agriculture.
