With the gradual emphasis on the construction of cultivated land quality in China and the continuous development of soil testing and fertilizer application, the analysis of soil agrochemical production in agricultural production is increasingly evident. To understand this, the key issues in soil agrochemical analysis are particularly important to soil and fertilizer workers.
Soil agrochemical analysis is an important part of the soil fertilizer work, and it is an important means and a necessary way for scientific fertilization. As people attach importance to the quality of cultivated land, the assessment of cultivated land quality must be conducted through scientific tests and analysis. As new types of fertilizers emerge in an endless stream, the quality of fertilizers must be tested. At the same time, due to the continuous use of pesticides, fertilizers, and plastic film, the environmental quality of the soil has undergone major changes. Monitoring of the soil's environmental quality must also be tested.
Soil agrochemical information collection system abbreviation agrochemical information collection system, is a kind of public opinion data processing equipment, automated soil testing and fertilization information acquisition, it brings greater convenience to soil workers!
According to the degree of processing and refining, it can be divided into three types: fully refined paraffin, semi-refined paraffin and crude paraffin.
Crude paraffin wax has a higher oil content and is mainly used for making matches, fiberboard, tarpaulin, etc. Fully refined paraffin and semi-refined paraffin are widely used, mainly used as components and packaging materials for food, oral medicine and certain commodities (such as wax paper, crayons, candles, carbon paper), coating materials for baking containers, used for fruit preservation , Insulation of electrical components, improve rubber aging resistance and increase flexibility, etc.
