MATERIALS AND METHODS Tests were carried out in Shidu, Changshan County, Zhejiang Province in 2012. Before the experiment, the field was idle field with medium fertility and loamy soil with good light and irrigation conditions. Three early indica rice varieties were planted and five transplanting density levels were set up, with a total of 15 treatments. Variety is early 39, temperature 814, Yongxian 69. The planting densities were 20.0cm × 13.3cm, 20.0cm × 16.7cm, 20.0cm × 20.0cm, 23.3cm × 10.0cm, 23.3cm × 20.0cm 5 treatments, 3 repetitions, a total of 45 cells, randomized block arrangement , The plot area is
