Is it better for wheat to pee before or during the New Year?

Urea can be properly sprinkled on wheat years ago, which is beneficial to promote the growth of wheat. For weak seedling plots, it is best to spread about 3-5 kg of urea in rainy and snowy weather. After the year, wheat is in the green period, so it is necessary to apply more nitrogen fertilizer to promote wheat growth through water and fertilizer management. Due to the low winter temperature in northern China, frozen soil layer has been formed in wheat field soil. At this time, urea is sprinkled on the snow, and it is just brought to the soil surface by snow water when it melts, which can better promote the absorption of wheat roots and promote the greening and jointing of wheat.
