Soil Testing and Formula Fertilizer Applicable to Soil Testing and Formula Fertilization
In modern agriculture, fertilization has had past experience. Fertilization has progressed to the precise fertilization stage. It is also to adhere to the principle of “one household, one soil, and lack of cropping and supplementationâ€. However, although the plan is a good plan, the slogan of soil testing and formula fertilization has been calling for many years. However, for many farmers, it is indeed difficult to truly conduct soil testing and formula fertilization, so they cannot accurately measure soil, but the soil testing The development and application of the formula fertilization instrument solved the problems of high soil nutrient detection cost and low efficiency, and truly enabled soil testing and formula fertilization to fall into place. In order to let farmers know more about their own land and to apply scientific fertilization, many grass-roots agro-technical departments or soil-fertilizer stations and chemical fertilizer suppliers are equipped with soil-testing and fertilizer applicators, which are different from traditional laboratory tests. The application of formula fertilization meter can be used regardless of the occasion, it can be used indoors, but also to the field in the field for on-site testing, and the instrument detection efficiency is high, in a short period of time can be obtained test results, effectively save The time required for soil testing and formula fertilization. Soil testing and fertilizer application are the basis for accurate fertilization and scientific fertilization. One of the cores of soil testing and fertilizer application is the application of soil testing and soil testing and fertilizer applicators. It is like sending soil doctors to farmers. Farmers know more about their own land, so that the fertilization scheme that is conducive to increasing production and increasing income by soil testing and formula fertilization is implemented. Farmers can scientifically apply fertilization according to the soil testing results of the soil testing and fertilizer applicator, which can also effectively reduce the planting cost, increase the fertilizer utilization rate, enable agriculture to increase efficiency, increase farmers' income, and protect the development of the ecological environment. This result is very beneficial to both the producers and the development of fine agriculture and eco-agriculture in China. Therefore, in the modern promotion of soil testing and formula fertilization, we can see more and more of the soil testing and formulated fertilizer applicators. The figure. Axial Flow pumps have lower heads but higher flow rates and are extremely versatile in low lift areas. The axial flow pump is divided into three types: vertical, horizontal and inclined, and its basic structure is the same. The impeller is fixed to the lower end of the pump shaft. There are usually 4 to 5 blades on the impeller. The blades are available in fixed, semi-adjustable and fully adjustable versions. The latter two can adjust the mounting angle of the blades within a certain range for efficient operation. The blades are bolted to the hub, the base of the blade is engraved with a reference line, and the hub has several mounting angular positions. The adjustment method is as follows: first remove the impeller, loosen the bolts, mobilize the blades to align the reference line with the required angular position line, and then tighten the bolt. This adjustment method is called semi-adjusting. The full adjustment is achieved by a special adjustment mechanism to adjust the blade mounting angle. The role of the guiding impeller is to convert the kinetic energy of the rotary motion of the impeller outlet liquid into pressure energy to avoid the impact and vortex loss caused by the rotation of the liquid.
