Abstract: A field experiment was carried out to explore the effects of three planting methods on the growth and yield of rice under the condition of high yield cultivation. The results showed that the planting method of wide-narrow row planting with evenly staggered populations and beds substantially enhanced the planting density, prolonged 3 to 4 days of the growth and development period of rice, improved the light and nutrient supply capacity, the content of chlorophyll and the light utilization efficiency, effectively increased the numbers of seedlings per unit area, effective panicles and filled grains, and the yield reached 11 711.11 kg/hm2, which was increased by 11.66% and 19.91% compared with the other two planting methods respectively. Under the experimental condition, the cultivation method of wide-narrow row with the evenly staggered planting populations and beds, and the planting density of 270,000 hole/hm2 would fulfill the high yield potential and reach the high output.
