摘要/Abstract

摘要： 以强冬性小麦品种京冬8号为对照,通过田间试验分析了非光敏特早熟小麦新品种冬早5号的冬前生长特性、抗寒特性以及产量结构。结果表明:冬早5号的临界致死温度(LT50)为14.9℃,比对照高出1.8℃,属于弱冬性小麦品种;冬早5号比对照早熟4d,增产43.4%,如采取有利抗寒措施该品种可以在北京及以南地区安全越冬。

Abstract: Taken the winter wheat variety Jingdong 8(JD8) with the strong winter hardiness as CK,the field experiment was conducted to study the growth characteristics before winter,winter hardiness and yield constitution of the new winter wheat variety Dongzao 5(DZ5),one of the non-photosensitive and extreme early mature wheat variety.The results showed that the critical temperature for mortality(LT50) of DZ5 was(-(14.9℃)),it is 1.8℃ higher than that of JD8,and it is a weak winter hardiness winter wheat variety.The harvest date of DZ5 was 4 days earlier and its yield was 43.4 % higher than that of JD8.DZ5 could over-winter safely in Beijing and the south areas of Beijing.
