The available phosphorus in soil, also known as available phosphorus, is a phosphorus component that can be absorbed by plants. Phosphorus content in plants is second only to nitrogen and potassium, and is generally higher in seeds. Phosphorus plays an important role in plant nutrition. Almost all important organic compounds in plants contain phosphorus. Phosphorus is involved in some processes such as photosynthesis, respiration, energy storage, and transmission of plants. Phosphorus also plays a catalytic role in the early formation and growth of roots, and the ability of plants to adapt to environmental conditions is conducive to the cold-tolerant winter of plants. For the determination of available phosphorus in soil, soil nutrient analyzer can be used for effective measurement and analysis, which provides a reliable and favorable basis for fertilizer application.
The soil nutrient analyzer was used to spatially interpolate soil sampling data in the autumn of 2007 to generate spatial distribution maps for each soil attribute raster format. Then, they are superimposed on the plot, and the average value of each soil attribute in each plot is calculated using the plot as a basic unit. The soil attributes are graded according to the average value, and the areas of soil properties in each grade of paddy field and dryland are separately counted. . The changes in nutrients in the soil of 597 farms were analyzed and the changes of available phosphorus content were plotted. Through the analysis of the change of available soil nutrient in the soil of 597 farm, the monitoring results reflect that the situation of low soil fertility in some areas can not be ignored. In the fertilization should pay attention to phosphorus reasonable cooperation, so that balanced fertilization, improve the utilization of fertilizers, in the master soil fertilization Based on the situation, according to the characteristics of required fertilizer and the law of release of fertilizers, the types, proportions, and amounts of fertilization should be determined to improve soil quality and achieve high and stable grain yield.
The content of soil available phosphorus in agricultural production was measured by a soil nutrient meter to guide the application of phosphate fertilizer. The available phosphorus content of soil is the main factor that determines whether or not the phosphate fertilizer has effect and size. Therefore, whether the phosphate fertilizer can be used must be treated differently according to the content of available phosphorus in the soil.
