| Abstract: | Different planting density experiment was carried out in the second accumulated temperature zone of Heilongjiang Province, with Suijing 4 and Kenjiandao 6. The results showed that the yield of row spacing 24.0 cm were higher than that of row spacing 30.0 cm, the highest yields in two type panicle of rice varieties were both at row spacing 24.0 cm and plant spacing 13.3 cm. |
