| 摘 要： | 采用温差、日长差的出穗日数对比和高温短日下出穗日数指标法,鉴定水稻光温特性。结果表明,天优3301感温性弱(1～2级)、感光性中偏低(4级)、基本营养生育期长(9级);天优3301在福建安全生长季种植,光敏期日长大多超过促进出穗临界日长,气温成为制约生育期的主要因素,当平均气温每升高1℃,营养生长期缩短4.4d,全生长期缩短8.4d;本田营养生长期日数和结实期日照是影响稻谷产量的重要生态因素。 |

| Abstract: | Photo-thermal characteristics of the hybrid rice,Tianyou 3301,were studied.By comparing the number of days from sowing to heading under different temperatures and day-lengths,as well as an indexing method of using the number of days from sowing to heading under high-temperature-short-day-length conditions,the ecological characteristics of the rice were obtained.The results indicated that Tianyou 3301 had a weak temperature susceptibility(Grade 1-2),medium photosensitivity(Grade 4) and long basic vegetative ... |
