| Abstract: | The effect of different transplanting density（33.3、25、20、16.7 hill per m2）on growth and yield of rice in cold region was studied using two different types of varieties Kongyu131 and Longjing26 as testing materials.The results showed that the suitable transplanting density for high tillering ability of high quality rice varieties was 30 cm×（16.7~20.0） cm and the suitable transplanting density of general tillering ability of rice varieties was 30 cm×（10.0~16.7） cm. |
| Keywords: | high quality rice in the cold different types of varieties suitable transplanting density |
