摘要
黑龙江省位于寒地,水稻冷害频繁发生。介绍了障碍型冷害发生过程、特点、伤害机理及其水管理技术,以减轻水稻冷害。结果表明:在水稻冷害敏感期即水稻孕穗期遇到低温冷害,应灌17cm以上水层。在水稻前历期灌10cm也起到防护作用。二者结合效果更好。
Heilongjiang province lies in cold region the chilling injure of rice is occur often. This article introduced the befall process of sterile-type chilling injure, characteristics, mechanism and the irrigation technique to decrease the chilling injure, especially about the effect of deep irrigation technique.
