Comparision of Dry Matter Accumulation Between Rice Nursing Seedlings Scatteringand Other Planting Patterns

This paper has studied dry matter accumulation and dry matter distribution of different rice populations. The results shows a very significant difference between economical yield and total dry matter accumulation and a very significant difference between economical yield and speed of dry matter accumulation from heading stage to tilling stage. The results also shows a very significant difference between economical yield and dry matter accumulation after heading stage. The speed of dry matter accumulation and dry matter accumulation after heading of nursing seedlings scattering (NSS) were lower.
