| 摘 要： | 在田间条件下,冬小麦(丰抗15)地上部硫浓度的最大值为孕穗期,含量为0.369％,地上部各器官中硫的含量亦为孕穗期最大,其茎、叶、穗中含硫量分别为0.327％,0.477％和0.283％。硫素在小麦植株中的累积高峰在孕穗期。累积的硫素主要分布于茎叶中。成熟期,籽粒中的硫占总量的一半左右。冬小麦自孕穗期后吸硫很少,主要是前期吸收的硫的转移,且硫的损失很大。

| Abstract: | The experiment was in the field. Sulphur concentration of wheat aerial aprts at boot atage was the highest. The content was 0.369 per cent.The highest sulphur concentration was at boot atage in every apparatus of wheat aerial parts. The sulphur concentrations were 0.327, 0.477, 0.283 per cent in the stem,leaf and ear.Sulphuric acumulation height of wheat of wheat plantwas at boot stage. The sulphur accumulation was distributed in stem and leaf. The sulphurin seeds was a half of total. wheat little absorbed sulfur after booting, but the sulphur was moved. The sulphur lost a lot. |
