The soil in Qinghe County is mainly chestnut-calcium, and the surface layer is dominated by maroon, and the organic matter content can reach about 2.5%. Chestnut soil is a soil formed under the semi-arid and semi-humid grassland climate conditions. Due to the cool climate, soil nutrient conversion is slow and the effectiveness is not high. Soil leaching is weak, calcification process and grassland humification process is strong, soil parent material is loess-like material, lime reacts strongly, pH is slightly alkaline, soil layer is shallow and thin, and crude system is strong.
The soil testing and fertilizer applicators analyzed the soil and found that with the increase of fertilizer application amount, the soil had an adverse effect, mainly in the increase of soil heavy metals and toxic elements, resulting in the accumulation of soil nitrate, destruction of soil structure, promote soil acidification, and reduce Soil microbial activity changes the soil properties, soil fertility, and reduces crop yields. Most of the farmers have very high chemical fertilizer application rates. This is due to the long-term single application of nitrogen and phosphate fertilizers resulting in the imbalance of nitrogen, phosphorus and potassium, resulting in large amounts of fertilizer, high cost, low utilization of chemical fertilizers, and poor efficiency.
Most of the farmer's household chemical fertilizer application is very high, this is due to a long-term single application of nitrogen and phosphorus fertilizer caused by the imbalance of nitrogen, phosphorus, potassium, resulting in a large amount of fertilizer, high cost, low utilization of fertilizer, poor efficiency. This not only pollutes agricultural products such as wheat and vegetables, but also pollutes the soil, water bodies, air and other ecological environments. In the popularization of soil testing formula technology, soil testing and formula fertilization apparatus also found that a large amount of fertilizer application and backward irrigation methods such as flood irrigation reduced the soil fertility of farmland, and soil salinization became more and more serious. The vast majority of people have not yet realized the potential danger of fertilizers on the soil environment and human health. Therefore, environmental protection awareness should be strengthened according to the law of crop manure requirements, soil nutrient performance and fertilizer effects, and soil and fertilizer monitoring and management should be strengthened; Appropriate amount and proportion of various fertilizers applied and corresponding fertilization methods.
Analysis of Soil Fertilizer and Fertilizer Applicator to Analyze the Relationship between Chemical Fertilizer Consumption and Environmental Benefits
The environment is the space on which human beings depend for survival. Adhering to the ecological priority principle and developing ecological and efficient agriculture are inevitable for agricultural development. Agricultural environmental protection work is a huge system project and it is related to the stability and development of agriculture. Fertilizer is the main agricultural product of agricultural production. It is the “grain†of crops. The level of fertilization directly affects the crop yield, especially the level of grain production. The quality of the fertilizer and the price level directly affect the income of farmers. At the same time, the fertilizer application technology of our country's peasants is lagging behind. Excessive partial application, unreasonable ratio, surface fertilization, flood irrigation after application, and application of unfaded barn fertilizer are more common. Soil testing and formula fertilization is an inevitable trend of agricultural development. Soil testing and fertilizer application instrument plays an important role in the popularization and application of this technology, and provides scientific and powerful support for formulation.
