The harm of improper application of fertilizer, the workers engaged in agricultural production have a personal experience, not only increase the direct input cost of the land, but more serious directly lead to soil health problems, affecting the healthy and sustainable development of agriculture, Therefore, in order to achieve the goal of improving quality and efficiency in agriculture, we need to pay attention to the issue of fertilization. The soil testing formula of the soil measuring instrument is to use the instrument to detect the nutrient content in the soil, and then according to the demand of the crops for different elements, scientific matching, balanced fertilization, lay a good foundation for the development of modern agriculture. Soil testing and formula fertilization is a scientific method to effectively avoid excessive fertilization and unreasonable fertilization during crop planting. It is also an advanced scientific fertilization technology widely used in developed countries such as Europe, America and Japan. Promoting soil testing and formula fertilization will help promote the transformation of fertilization operations in China from extensive to precise, and vigorously strengthen the quality of cultivated land and comprehensively enhance soil fertility. The soil measuring instrument is an important instrument used in soil testing and formula fertilization. The large-scale application of the instrument can be used as a science to help the farmers to fertilize scientifically, fertilize properly, and achieve considerable results in soil testing and fertilization. Economic and social benefits. At present, with the adjustment of the agricultural structure, the family-type small households' agricultural production is gradually decreasing, and the large-scale planting mode of cooperatives and demonstration gardens is on the rise. Under this background, how to ensure the fertilization is the enterprise on the basis of cost reduction. Issues that need to be considered. The soil testing formula can not only avoid the waste of fertilizer resources, but also the pollution of soil and environment caused by excessive fertilization. At the same time, it can ensure the growth demand of crops, improve fertilizer utilization rate, and improve crop yield and quality. Therefore, this scientific fertilization method is very suitable for the actual needs of China's current agricultural development, and has important practical significance for promoting the transformation and development of the fertilizer industry and agricultural standardization.
Brass has excellent CNC Machining Turning performance, high-speed machining turning under the brass can get excellent surface finish.
