小麦病毒病是一种在普通显微镜下观察不到的,非细胞形态的一种微小生物寄生小麦而引起的传染性病害。小麦受病毒侵染后生长发育受到影响,以致植株生长不良或畸形,有的甚至不能拔节而早期死亡;有的虽能拔节但不能抽穗;有的穗而不实或结实不良,籽粒瘪瘦,对产量影响很大。据在遵化县西铺大队和峰峰矿区临水公社新河大队测定结果,得黄矮病的小麦植株穗粒数减少百分之十三点六到百分之二十四点七,千粒重
Wheat virus disease is a contagious disease caused by parasitic wheat, a tiny organism that is not observed under ordinary microscopy. Wheat infected with the virus after the growth and development are affected, resulting in poor plant growth or deformity, and some even can not join and early death; although some can join but can not be heading; some spike but not real or bad, lean grain, Great impact on the yield. According to the result of the determination of Xizhip Brigade and Xinfeng Brigade of Fengshui Mining Area in Zunhua County, the number of grains per ear of yellow dwarf wheat decreased by 13.6% to 24.7%
