长春地区种植冬小麦生长发育规律的研究

The Study on Growth and Development of Winter Wheat Grown in Changchun

摘要:

1993~1997年在长春种植6个冬小麦品种, 9月中旬播种, 翌年6月底至7月初收获。冬小麦的总茎数各品种均在越冬前达最大值, 越冬后呈下降趋势。返青期、抽穗期的茎数、穗数与小区产量间呈显著正相关。

The number of total stems of winter wheat reached the highest before overwintering stage and declined after overwinter- ing. The coefficients of correlation of the number of stems in turngreen stage and heading stagenumber of spike with plot yield were positive significantly.
