草茵很容易感染多种病毒病，感染了病毒病的草莓果子一年比一年小、畸形，品质差，叶子皱，生长缓慢，一般减产３０％－８０％。并逐年加重。加上缺乏配套的高产栽培技术，草薄的经济效益大幅度下降，严重地阻碍了草莓生产的发展。脱毒苗具有极明显的增产效果。去病毒苗比未脱? Grass is very susceptible to a variety of viral diseases, the virus infected strawberry fruit year after year small, deformity, poor quality, leaf folds, slow growth, the general reduction of 30% -80%. And increase year by year. Coupled with the lack of supporting high-yielding cultivation techniques, a drastic decline in the economic benefits of straw, seriously hampered the development of strawberry production. Virus-free seedlings have a very significant yield increase. To virus vaccine than not off?
