Stable-yield cultivation method for rice in cold region

The invention discloses a stable-yield cultivation method for rice in a cold region, and relates to a rice cultivation method. According to the stable-yield cultivation method for the rice in the cold region, the yield and quality can be improved, and the problem of straw returning to the field is solved. According to the method, the water and soil conservation capacity and the energy storage capacity can be improved, a stable growth environment can be provided for rooting and germination of seeds and seedlings in spring in cold regions, and the adaptive capacity of the seeds or the seedlings to overlarge temperature differences is improved. Root systems of rice seedlings grow rapidly, the growth speed of the seedlings is increased, the proportion of deep root systems of the seedlings in the later period is high, and the yield and quality are improved. Due to the arrangement of the dense surface soil, the activity of microorganisms in the soil can be rapidly recovered, dominant strains are formed, the disease
