1988~1990年,将河南省的过渡型小麦品种在北京、郑州、贵阳三个试点播种.结果表明:依北、中、南的顺序,参试品种的全生育期天数逐渐减少,地点间差异极显著.全生育期天数与播种到生理拔节的天数有极显著正相关关系.播种~生理拔节~抽穗~成熟这三个生育阶段在北京、郑州表现“长~短~短”的特点,在贵阳则表现“短~长~短”的特点.从播种至抽穗,对日长无严格要求.播种~生理拔节、生理拔节~抽穗,都受温光互作的影响,其天数多少都和“平均光温积”呈极显著负相关.抽穗~成熟,在适温范围内,其天数与平均日均温呈极显著负相关.
From 1988 to 1990, the transitional wheat cultivars in Henan Province were sown in three pilot sites in Beijing, Zhengzhou and Guiyang.The results showed that the number of days during the whole growth period of the tested cultivars decreased gradually with the order of North, Central and South China, Extremely significant.The number of days in the whole growth period was significantly and positively correlated with the days of sowing to physiological jointing.These three growth stages of sowing ~ physiological jointing ~ heading ~ maturation showed the characteristics of “long ~ short ~ short” in Beijing and Zhengzhou, Guiyang has the characteristics of “short ~ long ~ short.” From sowing to heading, there is no strict requirement on the Japanese. Sowing ~ physiological jointing, physiological jointing ~ heading, are affected by temperature and light interaction, the number of days and “ Average solar thermal product ”was significantly negative correlation.Heading ~ mature, in the temperature range, the number of days and the average daily average temperature was extremely significant negative correlation.
