Specific method: When the snowfall reaches about 10 cm, evenly spread the non-volatile instant nitrogen fertilizer (such as urea) on the snow, generally apply 7.5-10 kg of urea in the mu, and the field with poor geotechnical conditions can increase the dosage appropriately. . Farmers can also spread into the field before the snowfall according to the weather forecast. After the snowfall, the fertilizer will be covered and melted into the soil together with the snow.
Note: The amount of snow is too small, it is difficult to completely melt the fertilizer, and the expected effect is not achieved, resulting in fertilizer loss.
Role: After the winter crops return to green, with the increase of temperature, the growth rate is accelerated, some crops have vegetative growth and reproductive growth at the same time, the requirements for water and fertilizer are very high, winter snow fertilization has achieved winter fertilizer and spring use, and solved the difference in soil fertility. The phenomenon of de-fertilization in the spring of the field promoted the transformation and upgrading of the seedlings and laid the foundation for high yield.
