在党和政府的大力倡导和支持下,我国的种草事业正在飞速发展。牧草种子调运频繁、品种繁多、数量巨大。然而,牧草种子绝大多数未经任何健康检验。长此以往,可能使许多危险性病害随种子而遍及各地,成为种草事业的威胁。 With the vigorous advocacy and support of the party and government, the cause of grass-planting in our country is rapidly developing. Forage seeds transported frequently, a wide variety, a huge number. However, the vast majority of pasture seeds have not undergone any health examination. In the long run, many dangerous diseases may be spread everywhere with the seeds and become a threat to the breeding industry.
