| Abstract: | Contrast test of community productivity were made between 3-5 seedlings per hole and 6-8 seedlings per hole by machinery transplant which use Huaidao-5 as testing material. The result indicated that 3-5 seedlings per hole was suited for rice population growth with high percentage of earbearing tiller, its leaf-area-index（LAI） and dry matter accumulation was significantly higher than treatment of 6-8 seedlings per hole, treatment of 3-5 seedlings per hole can achieve high yield. |
