Soil testing and formula fertilization is a key step to achieve modernization of agriculture. The growth of crops is inseparable from nutrients. Fertilizer is the most direct source of soil nutrients. How to maximize the benefits of fertilizers? How to minimize the impact of fertilizers on the soil environment? The soil tester can help us solve these difficulties. The soil tester can measure the nutrient status in the soil and provide us with scientific fertilization.
I. Significance and Connotation of Soil Testing and Formula Fertilization in Wheat
The so-called wheat soil testing formula fertilization refers to the field trials of fertilizers and soil testing as a basis, according to the law of crop manure requirements, fertilizer effects and soil nutrient performance, based on the rational application of organic fertilizer, put forward the trace elements, nitrogen and phosphorus The amount of potassium, the appropriate ratio, and the application technology, the application techniques referred to here mainly include the application method and the application time, so that the crop can be uniformly absorbed by various nutrients to achieve the balance between the three elements of potassium, phosphorus and nitrogen, inorganic nutrients and The balance between organic nutrients, the balance between trace elements and a large number of elements, maintains the level of wheat soil fertility, reduces pollution of the environment and nutrient loss, and achieves goals of high efficiency, high quality, and high yield. The implementation of soil testing and formula fertilization technology maximizes the positive effects of applying chemical fertilizers in agricultural production processes. At the same time, it minimizes the negative effects of chemical fertilizers on China's agricultural production, and it is the most central technology for establishing scientific fertilization systems. According to China's relevant technical specifications, fertilization techniques for soil testing formulas mainly revolve around the following five tasks: fertilization guidance, fertilizer supply, fertilizer application, formulation, and soil testing. These eleven tasks mainly include technology research and development. , Effectiveness evaluation, farmland fertility evaluation, database construction, publicity and training, demonstration and promotion, fertilizer processing, formula design, field experiment, sampling test, and field survey.
Second, wheat soil testing formula technology system
As the saying goes, crops depend on fertilizers, and fertilization has become the most direct measure to increase agricultural output. The World Food and Agriculture Organization of the United Nations (FAO) has conducted experimental research in forty-one countries for eighteen years and reached the conclusion that chemical fertilizer production increases. The effect accounted for 60% of the increase in crop production, up to a maximum of 67%. To establish a wheat soil testing formulation technology system, we must accelerate the continuous reform of the agricultural technology extension system, improve the service and promotion of soil testing and fertilizer application technologies, and implement agricultural technology promotion on the basis of the existing demonstration counties. The continuous reform of the system will improve the functions of agricultural technology extension services in townships and counties.
Strengthen the existing agricultural technicians' own training, accelerate the update of knowledge of agricultural technicians, and improve the ability of agricultural technicians to serve and the level of service. We will give full attention to the cultivation of talents for agricultural technology promotion in agricultural colleges and universities, and establish and improve a talent training system that serves the countryside and takes root at the grassroots level, and will continue to strengthen the construction of a talented person. The introduction of a new farmer, business, and government-to-government integration mechanism to Luoshan County requires a one-stop service that will do its utmost to fulfill its responsibilities and implement implementation, supply, distribution, and testing. Adhering to the principle of adapting to local conditions, implementing personalized and normalized services, establishing and improving a set of sound and effective normal mechanisms for monitoring soil fertility, realizing the normalization of soil testing and formula fertilization, and promoting China’s BB fertilizer production from universal to nutritional Package-specific, and ultimately the realization of personalized services. Based on the existing soil testing chemicals, soil testing methods, and soil testing methods, we will focus on research and development of new soil testing technologies and new varieties, improve soil testing methods, and improve the accuracy and efficiency of soil testing. Pay attention to the training of farmers' science and technology, guide farmers to change their own concept of fertilization, make rational fertilization and scientific fertilization deep into people's hearts, turn the passive into initiative, change the concept of farmers fertilizing, accompanied by the current continuous measurement and fertilization techniques In the promotion, farmers are changing the blind concept that “the more fertilization is better,†and farmers’ enthusiasm for learning scientific fertilization techniques is also increasing.
Third, the conclusion
A large number of experiments and the results of research and promotion have proved that the soil testing and fertilizer application technology is a practical agricultural technology with strong operability, technological content, economic benefits, ecological benefits, and social benefits. In this article, the author mainly studied the technical system of soil testing and fertilization in wheat from the significance and connotation of wheat soil testing and formulating and wheat soil testing formula technology system.
