Farmers engaged in agricultural production should be aware that in the process of cultivating crops, in addition to the key to the initial selection process, it is also important to fertilize the crops and promote the growth of the crops. It can even be said that the key to the crops is directly affected. Sexual growth, then how to properly and effectively fertilize? Let's take a look at the following. In the process of fertilizing crops, many farmers have not fully understood the key points of fertilization attention, especially in the case of low temperature in winter, crop fertilization should pay more attention to it, very particular about it, to know what fertilizers should be applied, and what fertilizers should be applied more. So which fertilizers are suitable for application in low temperature conditions in winter? Which fertilizers are not suitable for application? 1, carbon ammonium fertilizer should be applied Generally speaking, the temperature in winter is low. Therefore, ammonium bicarbonate is not easily decomposed and decomposed, which can effectively improve the utilization rate of fertilizer. Ammonium bicarbonate is an ammonia nitrogen fertilizer. After being applied to the soil, it can be directly absorbed and utilized by crops. It is a typical "quick-acting fertilizer"; according to the experimental results, it is proved that the winter wheat field can be applied with ammonium bicarbonate, and the fertilizer efficiency can be more than doubled in the hot season. 2. Phosphorus and zinc fertilizer application During the growth of crops, the absorption of phosphorus and zinc is directly affected by temperature and light. In winter, the temperature is low and the light is insufficient. It is easy to directly induce the lack of phosphorus and zinc deficiency in wintering crops. Therefore, during the fertilization process of crops in winter. Phosphate fertilizer and zinc fertilizer should be applied more to enhance the cold resistance of plants and prevent crop freezing damage. 3, urea bogey Urea is an amido-nitrogen fertilizer. It cannot be directly absorbed by crops after being applied to soil. It needs to be converted into ammonia nitrogen to be absorbed by roots under the action of urease secreted by urea bacteria in the soil. However, the conversion rate of urea depends mainly on the conversion rate of urea. The soil temperature, if the urea applied to the soil is all converted to ammonia nitrogen, it takes 7 to 10 days at a ground temperature of 10, 4 to 5 days at 20 o'clock, and 2 to 3 days at 30 o'clock. Therefore, the crop When applying fertilizer in winter or early spring, urea application tends to affect crop growth because of slow fertilizer efficiency; therefore, it is best not to apply urea during winter fertilization. The above is the introduction of winter fertilization attention points, farmers must be aware of the process of planting crops, in order to ensure that crops can get a better growth.
