摘要
1988～1990年,在北京进行了小麦生态试验.春型品种在晚秋播试验中存在着春蘖发生期,以侧茎成穗的方式完成生活周期,可以和冬型品种花期相遇,成熟期相近,千粒重较高.冬型品种在早春播试验中能抽穗、开花、成熟.0～15℃的温度和较短的日长相组合,保证了田间春化.春型和冬型小麦品种都有较广的生态适应范围.了解不同类型小麦品种在非正常播期中的生育表现,对小麦科研与生产,尤其在异常气候条件下的小麦生产具有一定的理论及实际意义.
Experiments of wheat ecology were conducted in Beijing from 1988 to 1990. Springness ecotype of wheat cultivars have tillering stage of spring in late sowing stage in autumn, these cultivars could complete their life cycle by side stem ear. Springness and winterness wheat cultivars could attain to same growth stages such as flowering and maturation in these sowing stages, springness cultivars could have better thousand-grain weight. In early sowing stages at spring, winterness wheat cultivars could attain to stages such as earing, flowering and maturation. The concert of 0-15℃temperature and shorter day-length were ensured vernalization in field for winterness ecotype of wheat cultivars. Springness and winterness wheat cultivars have wider scope of ecological adaptation.
