| 摘 要： | 本文用Blackman生长分析的方法,研究两品种四播期冬小麦干物质积累及其与产量形成的关系。结果表明:冬前积温和日均温度高,有利于冬小麦冬前干物质积累和返青后干物质积累以及产量的形成。播期对干物质积累速率(RGR)和群体生长率(CGR)及绿色面积系数(GAI)、叶日积(LAD)、叶面积相对生长率(LRGR)等均产生影响,而对净同化率(NAR)无大的影响;播期主要影响冬小麦绿色面积的生长,进而影响干物质积累和产量形成。适期早播有利于培育冬前壮苗和返青后干物质的积累及产量的提高。

| Abstract: | Applying the method of Blackman growth analysis studies on the relation between dry matter accumulation and yield formation among four seedling date and two species. It shows that the more accumulating temperature before winter and average temperature of per day were the more the dry matter accumulation before winter and after springing and yield formation, the seedling date influences the Relative Growth Rate (RGR) , Crop Growth Rate (CGR), Green Area Index (GAI) , Leaf Area Duration (LAD), Leaf Relative Growth Rate (LRGR), but it have little influence in Net Assimilation Rate (NAR), it mainly influences the growth of green and lead to infleuence dry matter accumulation and yield formation, it would take privelige in bringing strong stem and dry matter accumulation and higher yield if due and earlier seedling. |
