First, the concept of balanced fertilization    Balanced fertilization is the method of soil testing and fertilization. It is called balanced fertilization in the world. In the past, we called this technology the soil testing formula fertilization, which was named after the technical method. Briefly, the first is to measure the soil, take the soil sample to determine the soil nutrient content; the second is the formula, after the diagnosis of the soil nutrients, according to the nutrients needed for crops, “prescribe the prescription and the prescription according to the prescriptionâ€; the third is the rational fertilization, which is in agriculture. Scientific application of formula fertilizer under the guidance of scientific and technical personnel.    Balanced fertilization technology is an advanced agricultural technology promoted by the United Nations throughout the world. The Ministry of Agriculture has identified this fertilization technology as one of the key agricultural technology promotion projects. To promote this technology as soon as possible, the first choice is to make the majority of farmers friends know its principles. This is about the relationship between crops, soil and fertilizer. As we all know, the growth of crops is inseparable from the soil, and plant nutrients 60% - 70% are absorbed from the soil. There are many kinds of soil nutrients, which can be divided into three categories according to the absorption and utilization of crops. The first type is that the relative amount of soil is relatively small, and the crops are more absorbed and utilized. This is nitrogen, phosphorus and potassium, which are called a large number of elements. The second category is that the soil content is relatively high, but the crops need less, mainly silicon, sulfur, iron, calcium, magnesium, etc., called medium-quantity elements. The third category is that there is little soil and little crops, including copper, boron, manganese, zinc, molybdenum, etc., called trace elements. These nutrients contained in the soil are essential for the growth and development of crops. When the soil nutrient supply is insufficient, it is necessary to supplement it by fertilization to achieve the balance between fertilizer and crops. Second, the content of balanced fertilization technology    Balanced fertilization technology mainly refers to the scientific application of fertilizer technology. On the basis of soil diagnosis, analysis of crop fertilizer requirements, mastering the characteristics of soil fertilization and fertilizer release related conditions, determine the type of fertilizer applied, the ratio of fertilizer to fertilizer, according to the formula, and scientific application.    In a broad sense, balanced fertilization should include the combined application of agricultural fertilizers and fertilizers. Here, a metaphor can be used to supplement soil nutrients, apply fertilizer to fertilizer ratio as “food supplementâ€, and apply fertilizer to “medicine supplementâ€. People often say that "food supplement is better than medicine." Because farmyard manure contains a lot of organic matter, it can increase soil aggregate structure, improve soil water, fertilizer, gas and heat, not only can supplement the three elements of nitrogen, phosphorus and potassium in the soil, but also can supplement various medium and small amounts. element. Practice has proved that manure and chemical fertilizer, fertilizer use efficiency can be increased 5% --10%. When we promote balanced fertilization technology, we must not neglect the scientific accumulation and use of farmyard manure. Third, the benefits of balanced fertilization    From the practice of promoting balanced fertilization technology in recent years, this technology has obvious economic, social and ecological benefits. Specifically, there are four advantages.    First, balanced fertilization can effectively improve the utilization rate of fertilizers. Second, balanced fertilization can reduce agricultural production costs. Third, the effect of balanced fertilization to increase production and income is obvious. Fourth, balanced fertilization is conducive to the quality of agricultural products. Fourth, how to achieve balanced fertilization    Balanced fertilization technology is a more complicated technology. It is not easy for farmers to master it. Only after materializing this technology can it be realized. The one-stop service of measurement, distribution, production, supply and application is carried out by professional departments for soil testing and formulation. The fertilizer enterprises produce and supply the farmers according to the formula, and the agricultural technicians guide the scientific application. Simply put, the farmers directly buy formula fertilizer, and then apply according to the specific program. In this way, a complex technology has become a simple matter, and balanced fertilization technology can be truly applied to agricultural production in order to play its due role.
