Although soil testing and formula fertilization has been promoted in some places for nearly 5 years, it is still difficult to break through the actual promotion scale. The main reasons are: the cost is too high. Affected by the cost of chemical fertilizers, the price of formula fertilizer is not as low as the masses hope, affecting the promotion of formula fertilizer to a certain extent. Technology has faults. The formulation of soil testing and formula fertilization generally uses soil testing and formula fertilization query system. However, on the one hand, the development and popularization of expert systems must have a process. On the other hand, the expert system must follow the development and requirements of agricultural production, and the environmental changes need to be continuously upgraded. . In the existing soil-fertility technical team, there is a shortage of software development talents, and there are weak links in the development and application of soil testing and fertilizer application systems.
By encouraging and guiding enterprises to participate in soil testing and formula fertilization, enterprises have realized that carrying out soil testing and fertilizer application is a need for agricultural modernization, a requirement for adapting to market development laws, and an opportunity to adjust product structure, promote technology upgrading, and expand market space. . Through constant exploration and practice, the agricultural sector has established the concept of long-term operations, innovative technologies and open mindedness.
As a public welfare undertaking that benefits farmers and promotes the sustainable development of agriculture, soil testing and formula fertilization should be persistent. Expand the scope of services for farmers, improve service methods, and gradually meet the fertilization needs of thousands of households, different plots, and different crops; establish a land evaluation system to provide scientific information for the establishment and improvement of scientific fertilization indicators, optimization of fertilization structure, and adjustment of fertilizer production layout The basis is to meet the needs of macro-management of cultivated land and fertilizers; to develop a soil testing and fertilizing query system to realize information sharing and to promote the transformation and utilization of results in more areas and in a wider range.
The benefits of using chemical fertilizers in a short period of time are very good, not only can promote the production of crops, but also increase production. Therefore, there is a large amount of chemical fertilizers in rural areas. However, due to blind application of chemical fertilizers and excessive fertilization, waste of fertilizer resources, increase in production costs, and even environmental pollution are caused. In order to promote the cost-saving and efficiency of modern agriculture in China, and promote the quality of cultivated land, in order to promote grain production, increase income, and improve economic efficiency in rural areas, soil testing and fertilizer application must be applied. In the continuous improvement of soil testing formula technology, the soil testing and fertilizing inquiry system is also constantly improving and applying, which also promotes the promotion of soil testing and fertilizer application.
