| Abstract: |
| To obtain the best cultivation method and achieve high and stable yield of rice，super rice huahang
No.31 was selected as the experimental material to study the tillering dynamics and yield characteristics under
different seedlings per hill（ A）and planting densities（D）. The results showed that under the same conditions
of seedlings per hill，the growth and cutting rate of tillers was D1>D2>D3. Under the same conditions of planting
densities，the growth and cutting rate of tillers was A6>A4>A2>A1. The effects of seedlings per hill and planting
densities on yield of huahang No.31 were significant or very significant . The order of influence effect was A ＞ D ＞
A×D. The treatment A2D2 with 2 seedlings per hill and planting density 2.4×105 collections/hm2 had the highest
yield of 6 584.0 kg/hm2. In the actual production，suitable decreasing seedlings per hill and suitable planting density
will be helpful to coordinate the relation between groups and individuals，and exert the high yield potential of huahang
No.31. |
