摘 要: | 分布方式对水稻群体的分蘖数影响显著,有序群体可以提高群体的分蘖能力,在最高分蘖期有序群体的分蘖数比无序群体大,在成熟期有序群体的有效穗数显著高于无序群体.在灌浆中后期有序群体的茎鞘干重较大,茎秆的充实度较高,可以提高群体的抗倒能力.

The Haulm and Tiller Emergence Effect about Distribution Model to Different Panicle Type Rice Population |
| |
Abstract: | Distributing model had influence on number of total tillers of rice population.Number of total tillers in ordered population was much more than that of in out-of-order population in tilling stage.The fertile spike number in ordered population was also much more than that of in out-of-order population in matures stage.The fertik spike mumber in ordered population was also much more than of in out-of-order popolation in matures stage.Stem and sheath,which were full of the filling,were much weight in ordered population,and the lodging degree was low. |
