[Effects of rice seedlings horizontal distribution on the dynamics of rice population, canopy light transmittance rate and panicle characteristics].
The study with stronger tillering hybrid rice ' D-you 527' showed that the more the irregularity of the seedlings horizontal distribution, the more colony stem-tillers the plants would have. Such a difference was significant 34 days after transplanting, but not significant at full heading stage. After transplanting, the trend that the variation coefficient increased with increasing irregularity of horizontal distribution presented gradually, and the difference became significant after jointing stage. Comparing with uniform distribution, an irregular horizontal distribution of the seedlings could benefit the canopy light transmittance rate and the panicle characteristics of rice.
