Should I apply urea to wheat before the Chinese New Year?During the period around the Spring Festival, urea should be applied to the wheat field. Spreading urea directly on the snow: This method of spreading urea directly on the snow is indeed effective, but this method is only suitable for winter wheat planted in northern China. This is because the temperature in northern my country is low in winter and the soil in the wheat fields has formed a permafrost layer. At this time, if urea is sprinkled on the snow, the urea will be brought to the soil surface by the snow water when the snow melts, which can better promote the absorption of the wheat roots and promote the greening and jointing of wheat. The most efficient topdressing method for spreading urea in wheat fieldsExperienced farmers know that urea should be applied to wheat fields during the period around the Spring Festival. However, many farmers have doubts. Some people say that it is better to spread urea directly on the snow, while others say that it is better to wait until the snow melts before applying urea. In fact, from a scientific point of view, both methods are correct. The only difference is that the wheat comes from different places and the conditions of the wheat fields are different, so the disagreement arises. Directly sprinkle on snow:Spreading urea directly on the snow is indeed a good method, but this method is only suitable for winter wheat grown in northern my country. This is because the temperature in northern my country is low in winter and the soil in the wheat fields has formed a permafrost layer. At this time, sprinkle urea on the snow. When the snow melts, the urea will be brought to the soil surface by the snow water, which can better promote the absorption of wheat roots and promote the greening and jointing of wheat. Spreading after snow melt:Spreading urea after the snow melts is applicable to wheat fields across the country. When the snow covering the wheat melts, it provides sufficient moisture to the soil. At this time, spreading urea on moist soil can better promote the decomposition of urea and help wheat absorb it. However, compared with spreading urea directly on the snow, the disadvantage is that the fertilizer will volatilize and reduce the fertilizer effect to a certain extent. How to apply fertilizer to wheat before and after the Spring Festival for better effect①Scientific use of fertilizer: Wheat is in the greening period around the Spring Festival, and the demand for nitrogen fertilizer is relatively high at this time. Therefore, when farmers apply fertilizers, they cannot blindly apply compound fertilizers or other fertilizers. They can use Tianqing Mineral Source humic acid liquid nitrogen fertilizer instead of urea and save time and labor by spraying it on the leaves. At the same time, it promotes the rapid replenishment of nitrogen fertilizer, improves the soil and promotes the formation of soil aggregate structure, accelerates the growth and rooting of capillary roots, improves the wheat's ability to absorb fertilizer and water, improves the wheat's ability to resist cold and drought, has a good resistance to late spring cold, and increases yields by more than 30% per mu. ② Reasonable dosage: Applying fertilizer to crops is actually the same as eating for people. You must pay attention to the amount when applying fertilizer. Many farmers want high crop yields, so they think that using more fertilizer will do. In fact, the nutrients required by crops are fixed. Applying too much topdressing is just like eating too much, which is harmful to the growth of crops. Therefore, when applying topdressing, it is enough to use a reasonable amount. Do not apply too much blindly, which will cause crop yield reduction. |
