Formula Fertilizer is Formulated Special Fertilizer (BB Fertilizer)
Formulated fertilization is formulated special fertilizer (BB fertilizer) Soil testing and formula fertilization technology is a comprehensive set of scientific fertilization techniques such as soil testing, fertilizer testing, special fertilizer formulation, and fertilization technical guidance for the purpose of achieving balanced fertilization. It is also a relatively advanced scientific fertilization technology that is widely used in the world. The core content of this technology is to determine the appropriate amount and proportion of trace elements in nitrogen, phosphorus and potassium fertilizers according to the results of soil testing, laws and characteristics of fertilizers needed for crops, combined with fertilizer effects, and targeted and scientifically determined Special fertilizers for crops are supplied to farmers and they are used by farmers. The biggest advantage of this technology is that it can effectively solve the contradiction between crop fertilization and soil fertilization and crop fertility requirements. Targeted supplementary crops need nutrient deficits, scientific and rational use of fertilizers, lack of what elements of the soil to supplement what elements, what elements of the crops need to add what elements, how much to add, so that a variety of nutrient balance supply to meet crops Demand, to improve the output of agricultural products, improve the quality of agricultural products, improve the competitiveness of agricultural products market, improve the utilization of chemical fertilizers and the use of benefits. China has complex soil types, large changes in soil nutrients, and low utilization of chemical fertilizers. At present, there are serious imbalances in the use of nitrogen, phosphorus and potassium fertilizers in China, resulting in excessive application of nitrogen fertilizers, insufficient phosphorus and potassium fertilizers, especially insufficient potassium fertilizers, resulting in fertilizers. The increase in production efficiency and use efficiency have decreased significantly. In addition, with the application of new technologies such as soil, plant test and diagnosis, expert fertilization system, formula fertilizer, and special fertilizers in recent years, the soil testing and fertilizer application technology has become increasingly sophisticated and mature, and it has met the conditions for large-scale application. If the soil testing and fertilizer application technology can increase the national coverage rate from 30% to 60%, the equivalent of 900 million mu of cultivated land will receive technical services and will increase grain production by 26 million tons. Therefore, it is imperative to further increase the popularization and application of soil testing and fertilization techniques, and gradually realize the balanced application of the three elements of NPK. It is imperative to maintain the stability and continuity of this work. At present, the research and application of soil testing and fertilizer technology is still relatively low in China. The main reasons are as follows: On the one hand, agriculture-related departments and fertilizer production and circulation enterprises have been conducting soil testing and formula fertilization for many years, but their fertilization guidance models still remain. In the traditional fertilization instruction model, "only prescriptions do not get drugs" stage, some companies only to test their soil for the promotion of their products, did not really measure the soil, after the formula, and then fertilization. It is difficult for the farmers to grasp this kind of prescription alone, and it is difficult to implement, which results in the fact that soil testing and fertilizer application techniques are not widely used. Through soil testing and formulating fertilization technology, soil, post-formulation and re-fertilization were first implemented to implement “comprehensive measurement, unified allocation, and unified supplyâ€, and the soil testing and fertilizer application technology was fully materialized into special fertilizers for popularization and application. This mode of fertilization guidance that both prescribes and prescribes medicine is widely accepted by farmers and their use. On the other hand, due to people's lack of understanding of the special nature of long-term continuous soil testing, fertilizer testing, and formulation renewal, it is believed that "the old technology is being carried out year after year, and it lacks new ideas." In recent years, investment has become less and less, resulting in Lack of promotion and financial support at the grassroots level. To this end, if we want to change the promotion of soil testing and formula fertilization in China, the most effective method is to use balanced fertilization as the dominant technology, with fertilizer structural adjustment as the key, and unified, unified, and unified supply as the basic forms. Measurement, distribution, production, supply and application of one-stop service to increase fertilizer utilization. In simple terms, formulating formulas based on soil testing results and laws governing crop manure, soil fertility, fertilizer utilization, etc., using high-quality chemical fertilizers to produce formula fertilizers, directly supplying farmers with fertilizers, and simplifying complex formula fertilization techniques. Formulated fertilization is formulated special fertilizer (BB fertilizer). BB fertilizer and English literal translation are blended bulk fertilizers (BB fertilizers). Based on soil nutrient differentiation tests, scientific calculations of nitrogen, phosphorus, and potassium are based on the law of crop manure requirements, soil nutrient performance, and chemical fertilizer efficiency. Special fertilizers formulated with the amount of elements and trace elements. The reality is to physically mix the different types of fertilizers in pellets according to the proportion of demand. BB fertilizer has the following advantages: First, the N, P, and K nutrient ratios are flexibly formulated to meet the different needs of crops for nutrients. After the application, the effect is obvious, and the balanced and matched fertilization techniques are actually implemented; second, the amount of fertilizer is reduced, and the utilization rate is improved; Easy to use, labor safety. The nutrient content of the fertilizer is high (more than 40% of the active ingredient), and it is convenient to use in granular form; the fourth is to increase production and income by cost-saving. Due to the reduction in the amount of fertilizers and labor, the cost per mu can be reduced by about 20 yuan, and the general increase rate is from 5% to 15%. Therefore, in the developed countries in the world, BB fertilizer accounted for more than 80% of the total amount of fertilizer. China has just started in this area, and BB hypertrophy has a promising future. It can be said that it is the direction of future fertilizer development. It is understood that through the application of BB fertilizer, chemical fertilizer utilization can be increased by 8 to 10%, output increased by 8 to 15%, and the overall benefit increased by 15 to 30%. In the final analysis, BB fertilizer is precise formula fertilization technology. The first is that the formula should be accurate. In order to do this, the soil testing and formula fertilization technology is truly implemented. The specific recommendations are as follows: First, determine the technical route for soil testing and formula fertilization. Based on soil fertility, crop fertilizer requirements, fertilizer effects, and climatic factors such as soil testing and fertilizer application, the soil testing and fertilizer field experiments were conducted to find out the laws of soil nutrient supply, crop fertilizer requirements, and fertilizer effects, and obtain and correct Formula fertilization parameters, establish formula fertilization models for different crops and different soil types. According to the soil test results and relevant conditions, the application of formula fertilization model, combined with expert experience, put forward fertilization formulas, from the fertilizer station to formulate special fertilizer according to the formula, supply it to farmers, and provide fertilization technical guidance. At the same time, through the monitoring of fertilizer quality, the quality of various fertilizers is guaranteed. Through the integrated service technology route, the socialization and industrialization of technology promotion will be gradually implemented to ensure the accuracy and in-place rate of soil testing and formula fertilization, and to increase the penetration rate of soil testing and fertilizer application. Secondly, in the promotion work, the following work should be clearly defined: First, establish a data system for crop fertilization indicators. In the main production areas of major crops, targeted surveys and tests were conducted to determine the effects of crop growth and fertilization, such as soil texture, soil organic matter, soil nutrients, farmers' fertilization levels, fertilization structures, and fertilization effects. Soil testing was conducted. On the basis of basic understanding of regional soil nutrients, combined with China's major soil type distribution, crop layout, fertilizer requirements and natural climate conditions, crop fertilization zoning. Based on the dominant crops in the fertilization zone, index data for guiding crop fertilization was established. According to the fertilization zoning and survey results (previous + supplementary), a unified and standardized field experiment was conducted on the main crops in the dominant area, including different fertilization methods, different fertilization periods, different fertilization amounts, etc., and relevant fertilization parameters were obtained. The second is to improve the test method. The method of combined leaching and joint determination was used to analyze the nutrient analysis of the basic soil samples and plant samples in the field test area. To explore the response of different soil fertility and crop growth to fertilization, and provide evidence and verification for the establishment of crop fertilization data indicators. The third is to establish a fertilization expert system. Through analysis and treatment of field tests, soil and plant test data, a database of fertilization parameters was established, and fertilization data indicators for different regions, different cultivation methods, and different crops were established. A computerized fertilization expert system was established for different fertilization zoning, soil, crop, climate, and risk factors. The man-machine intelligent system was used to simulate the fertilization patterns of the main crops, and the recommended fertilization was carried out. Economically reasonable fertilization methods, fertilization periods, fertilization amount, fertilization ratio and the like were proposed. The fourth is propaganda and training, demonstration and promotion. Organize provincial test and test technicians to train new test methods, master joint extraction and joint test technical specifications, ensure test quality, improve test efficiency, and reduce test cost; organize provincial, municipal, county, and town agricultural technicians to perform computer fertilizer application Expert system training, master the application of software, correctly understand and apply computer "recommended" fertilization program. And for the dominant producing areas and crops, the soil testing and fertilizing technology demonstration and promotion. At the same time, the promotion of soil testing and fertilizer application must be consistent with the development of agricultural industrialization. In the industrialization of agriculture and the production of high-quality agricultural products, the production of pollution-free foods, green foods, and organic foods has been promoted on a large scale. Higher demands have been placed on balanced fertilization. New changes have taken place in the functions and goals of fertilization; The second is to improve the quality of agricultural products; the third is to increase the quantity of agricultural products; the fourth is to reduce the production costs of agricultural products; the fifth is to enhance the resilience of crops; and the sixth is to improve the market competitiveness of agricultural products. . In order to achieve these goals, we must take appropriate measures and measures for fertilization. First, we must strengthen the dynamic monitoring of soil nutrient status, master the dynamic changes of soil nutrients, determine the type and quantity of fertilization according to the characteristics of crops to be fertilized, and achieve soil testing. Formula fertilization, and use soil testing and formula fertilization technology as the main content and technical measure of agricultural industrialization construction, and closely integrate the construction of featured agricultural product processing bases, improved seed bases, high-quality special grain and oil bases, high-quality commodity vegetables, and fruit bases, and where to take the base plan. , Where to collect the soil samples, special fertilizers, and where to supply them. Soil samples were collected, research formulas were formulated, and special fertilizers were integrated for the system, and the targeted, specific and scientific nature of special fertilizer formulas were constantly enhanced. The second is to increase the proportion of organic fertilizers, reduce the proportion of chemical fertilizers, and achieve a balance between organic fertilizers and chemical fertilizers. Third, reduce the proportion of nitrogen fertilizers, increase the proportion of phosphorus and potassium, and achieve the balance between the three elements of nitrogen, phosphorus and potassium; The balance between nitrogen, phosphorus and potassium and the trace elements; Fifth, we must strengthen the technical guidance for farmers' training and fertilization, vigorously improve the fertilization technology, and gradually realize the transformation from single fertilizer to compound fertilizer, compound fertilizer to special fertilizer, and reduce fertilizer waste. The effect of increasing production is good, the cost is reduced, and the utilization rate and use efficiency of fertilizer are increased. In addition, governments at all levels must strengthen their leadership in promoting soil testing and fertilizer application techniques. Establish a three-tier soil testing and fertilization technology promotion network in the county and villages to form an overall synergy, increase the popularization and application of soil testing and fertilizer application technologies, and increase the application level. Widely utilize social forces and social funds to accelerate the promotion of soil testing and fertilizer application. In the six key technical aspects of soil preparation, soil testing, formulating, fertilizer application, fertilizer supply, and fertilization, we will do a solid job for agricultural services. Of course, if we really want to implement the soil testing and formula fertilization technology, we must also do a good job supporting services. At present, the overall level of sales of agricultural products in China is not high, and most of them are still in a primary sales stage. Although many companies are improving their service levels, most of them have done superficially. In the development of BB fertilizers, the sales of fertilizers is a crucial agrochemical technology support. Such as pre-sale training, teaching farmers how to balance fertilization; the sale of the user to follow-up investigations, find problems and timely guidance; after-sales investigation and analysis of results, sum up experience. Only by truly and sincerely doing a good job can we bring about the great development of the soil and fertilizer business. In addition, we must create a healthy and orderly development environment for BB fertilizers. On the one hand, to achieve the development of BB fertilizer production, it is very important to rely on the strength of industry associations. Organize a large number of fertilizer production companies, exchange information, and face common problems, so as to promote the healthy development of BB fertilizer industry. On the other hand, the relevant industry management departments are urged to expedite the development of product quality standards. If standards are in place, the development environment of the entire industry will be more healthy and standardized, and BB fertilizer will develop rapidly in China, thus promoting the promotion of soil testing and fertilizer application technologies. application.
