| 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。 |
| 关 键 词： | 水稻 防碍型冷害 生理 灌溉技术 |

| Abstract: | 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. It showed that should irritate the layer of water of above 17cm in rice boot stage, when run into low temperature cold to suffer from, it named rice being cold to hurt sensitive issue, and irrigation with 10cm of water that can play a role in protecting too. The result will be better if we combine the two kinds of methods. |
