强春性小麦品种的田间春化反应及在贵州省的种植前景

Response to Field-vernalization by Strong Springness Wheat Cultivars and Its Planting Prospect in Guizhou

1984～1985年在贵阳对强春性小春品种“辽麦6号”、“76-63-1”、“粤麦6号”共进行了8期春夏播,试验表明这些品种生育早期对温度、日长要求不严格,田间种植无春化反应,播种至生理拔节天数随日均温增高而减少,生育天数也相应缩短。它们具有广泛生态适应性,在贵州除作秋播外,也可作春播、夏秋播,能获得较好产量,有广阔利用前景。

Three cultivars of strong springness wheat, Liaochun No. 6 ,76-63-1 and Yuemai No. 6 were divided into eight periods sowed at spring and summer in 1984 to 1985. Experiment find that these cultivars has no strict demands to temperature and day-tength in early phase of growth and development and also has no vernalization when growth in field. The results shows that the days of sowing to phsi-elongation stage are gradually reduction during day-average temperature are gradually getting higher. Due to these cultivars has wide range of ecological adaptation, so it was can obtain better yield when they sowed at spring and summer-autumn except used for sowing autumn in Guizhou and its will have wide developmental prospect.
