There are many factors that determine the yield of rice in the process of rice planting. The treatment of seeds before sowing and the management of the breeding process are all important factors, and a reasonable fertilization method determines the key factors for the high yield of rice. Rational fertilization must consider the soil, and fertilization is only needed if the soil is insufficient for a certain nutrient supply. After the fertilizer is applied to the soil, there will be some changes in the soil, which will affect the fertilizer effect to varying degrees. Without considering the soil, there will be no real rational fertilization. To this end, advanced instruments, such as soil composition analyzers, are required to perform effective measurements and analysis of soil-related nutrients and fertilization measures based on these criteria.
The soil nutrient environment of the crop includes: physical environment, chemical environment and nutrient environment. The physical environment of the soil first affects the moisture and air supply of the crop and also directly affects the supply and conservation of nutrients. The soil is composed of particles of different sizes. These particles constitute the three phases of the soil, namely the solid phase, the liquid phase and the gas phase. Generally fertile soil, its solid phase accounts for more than half of the entire soil volume, and less than half the volume, full of moisture and air. Soil pores not only bear the crop moisture and air supply, but also have an important role in crop growth. They also directly affect the diffusion of nutrients in the soil. Soil clay, soil organic matter and soil acidity are important factors affecting the soil chemical environment. Soil nutrients play an important role in plant growth even in the case of fertilization. It is estimated that under normal fertilization conditions, when the medium yield level is reached, 30% to 60% of the nitrogen absorbed by plants, 50% to 70% of phosphorus, and 40% to 60% of potassium are from the soil, indicating that the soil nutrient environment is The important role of crop nutrition.
Soil testing is the premise of soil testing and formula fertilization. The analysis of soil nutrients by soil composition analyzer can accurately grasp soil nutrient status and fertilizer supply performance, and provide scientific basis for formula fertilization. On the basis of soil testing, according to the soil characteristics, cultivation habits, crop manure requirements, production levels and climate conditions, combined with the previous year's yield level, determine the target yield, and then based on the effect of fertilizer, put forward nitrogen, phosphorus, potassium The most suitable amount and the best ratio. In accordance with the formula requirements, select high-quality single fertilizer or special fertilizer, compound fertilizer, organic-inorganic compound fertilizer and other fertilizer varieties for scientific matching, and then according to the type of soil, crop reproductive characteristics and fertilizer requirements, develop a corresponding fertilization model.
Soil nutrients were measured using a soil composition analyzer, and the fertilization mode of rice was determined. Rice soil testing and formula fertilization need to be determined by soil production, fertilizer production, due to lack of supplements, organic-inorganic combination, and NPK equilibrium. The principle of application. In order to ensure high yield and stable rice production, higher economic benefits can be achieved.
