Nine points of formula fertilization technology

The soil testing and formula fertilization technology should focus on the following nine tasks in the following five links: "soil testing, formula, fertilizer application, fertilizer supply, and fertilizer application guidance".

First, the field test through the field test, to grasp the different fertilization units of different crops fertilizer, base fertilizer, top dressing distribution ratio, fertilization period and fertilization methods. Find out the basic parameters such as soil nutrient content, soil nutrient supply, crop nutrient requirement and fertilizer utilization, etc. to provide basis for determining fertilizer formula.
Second, the soil test through the soil nitrogen, phosphorus, potassium and other elements of the nutrient test, find out the soil fertility.
Third, formula design Based on field experiments, soil nutrient content, and climate, landforms, soil, farming systems, etc., design fertilizer formulations of different crops.
Fourth, the calibration experiment in the fertilization area set the formula fertilization, farmers customary fertilization, blank fertilization three treatments, the main local crops as the object of study, the effect of formula fertilization to increase production, adjust the fertilization parameters, improve the fertilizer application formula.
V. Production of Formula Fertilizer According to the formula of fertilizer, the formula fertilizer is produced. The physicalization of formula technology is the key to improving and popularizing the techniques of soil testing and formula fertilization.
VI. Demonstration and promotion Establish a demonstration area for soil testing and formulating fertilization, establish models for farmers, and fully demonstrate the technical effects of soil testing and formula fertilization.
Seven, propaganda, training, publicity and training Soil testing and fertilizer application technology is an important means to improve farmers' awareness of scientific fertilization and popularization of soil testing and fertilizer application techniques.
VIII. Effect Evaluation The actual effect of soil testing and formula fertilization was verified. Feedback information was obtained in a timely manner and the management system, technical system and service system were continuously improved.
Nine, technology research and development focus on field trial methods, soil nutrient testing techniques, fertilizer preparation methods, data processing methods and other aspects of research and development work, and constantly improve the level of soil testing and fertilizer application technology.
