| 摘 要： | 以北京、天津、菏泽、驻马店、商丘、阜阳6个站点为代表,分析了黄淮海平原2004-2005年冬季冬小麦的冻害成因.研究表明,冬小麦冻害的发生主要是由于从小麦播种至当年12月20日积温过高,造成部分麦田在入冬前就完成了6-8片叶的生长,甚至进入了拔节期,再加上从当年12月20日至次年2月底黄淮海大部分地区气温比常年偏低1.3℃左右,且冷暖交替突变,麦苗抗寒锻炼不足,春性品种过多和播种量过大等原因. |

| Abstract: | Heavy frozen damage to winter wheat occurred in Huanghuanhai plain in 2004 -2005. The cause analysis of the damage was conducted based on meteorological data of six representative stations in Huanghuaihai plain, including Beijing,Tianjin, Heze, Zhumadian, Shangqiu and Fuyang. In this study, winter in 2004 -2005 was divided into two periods by 20th Dec. The accumulated temperatures from Ist Oct. to 20th Dec. at all stations were extremely higher as compared with the average annual values; however, the temperatures became extremely lower during period from 21st Dec. to 28th Feb. Under such excellent thermal condition before 20th Dec. , wheat plant developed rapidly and about 6 - 8 expanded leaves were obtained. In some areas, wheat plant even came in shoot elongating stage, and in this growing stage the ability of wheat seedling in resisting freeze became very low. On the other hand, the abrupt change in temperature after 20th Dec. induced low freeze-resistant ability due to lack of anti-freeze-exercise. Furthermore, the prevalence of spring-sown variety was also considered as an important reason for the heavy frozen damage in 2004 -2005. |
