根据谷子播种期长的特点,我们以播期为前提,探讨了晋谷14号的生长发育规律。结果表明,播期与干物质积累的关系以中播处理积累量最大,早播次之,晚播较低。穗分化与叶令指数的关系,比穗分化与叶片数的关系较为紧密,可以叶龄指数判断穗分化进程。灌浆高峰期(TMAX.G)出现的早迟,随播期推迟而提前,最大灌浆强度(G.MAX)则随播期推迟而增加。
According to the characteristics of the long sowing period, we sow the sowing date as the prerequisite to explore the growth and development of Jin Gu 14. The results showed that the relationship between sowing date and dry matter accumulation was highest in middle sowing, followed by sowing in early sowing and lower in late sowing. The relationship between spike differentiation and leaf index is more closely related to the number of leaves than to spike differentiation. The leaf index can be used to judge the process of spike differentiation. The early stage of the peak filling period (TMAX.G) was earlier than the sowing stage, and the maximum grouting intensity (G. MAX) increased with the delay of sowing date.
