新疆四周高山环列,并有大戈壁同内地农业区隔离,过去在交通阻塞的情况下,限制了许多危险性病、虫、杂草传播。据调查统计:新疆农林果蔬上的主要病虫仅有300多种;全国32种检疫对象,在新疆发现的也只有8种,同时新疆有的一些危险性病虫杂草,在内地却没有发现,或者很少。近十年来,随着社会主义建设事业的飞跃发展,交通状况逐步改善,往来人员和物资交流日益增多,这也为病、虫、杂草的传播提供了条件。
Surrounded by high mountains and surrounded by big mountains in Xinjiang, there is a large desert that is isolated from the agricultural areas in the hinterland. In the past, many dangerous diseases, insects and weeds were restricted in traffic congestion. According to the survey and statistics, there are only over 300 kinds of main pests and diseases on fruits, vegetables and fruits in Xinjiang. There are only 8 kinds of quarantine objects found in Xinjiang and only 8 kinds of dangerous pests and weeds in Xinjiang are not found in the Mainland , Or rarely. In the past decade, with the rapid development of socialist construction, traffic conditions have been gradually improved and personnel and material exchanges have been increasing. This has provided conditions for the spread of disease, insects and weeds.
