自70年代初期以来,青椒生产一直受病毒病的危害,特别是甜椒种植比例较大的地区,其损失往往以几何级数上升。一些地方采取叶面喷撒硫酸锌、叶面喷氮以及播前种子消毒等防治措施,虽能减缓一下病毒肆虐的势头,但由于只是改变了外部环境,或是减少了一些外部毒原,所以收效不是很大。 Since the early 1970s, the production of green peppers has been harmed by virus diseases, especially in areas where the proportion of sweet pepper plants is high, and their losses often increase in geometric series. In some places, the prevention and control measures such as foliar spray of zinc sulfate, foliar nitrogen spraying and pre-sowing seed disinfection can slow down the momentum of virus ravaging. However, since only the external environment is changed or some external toxins are reduced, The effect is not great.
