摘要 |
[Objectives] This study was conducted to find out the best sowing date and sowing rate of rice. [Methods] Based on the technique of dry seedling raising in aperture disk, the effects of sowing date and sowing rate on rice yield were studied. [Results] Sowing date and sowing rate per hole had obvious effects on tillering dynamics, growth process, number of panicles per unit area, number of filled grains per panicle and rice yield of rice developed from dry-raised seedlings. The comprehensive analysis showed that the highest yield was 10 285.5 kg/hm2 with the sowing date of May 20 and sowing rate of 5 grains/hole. [Conclusions] This study provides theoretical support and data support for the popularization and application of rice developed from seedlings dry raised in aperture disk. |
