Monitoring Advantages of Agricultural Environmental Monitoring Stations for Agricultural Environment

The first step in carrying out environmental quality monitoring is to formulate a monitoring plan and to obtain accurate information on the environmental quality from the monitoring results. It is more important than the advanced level of the agricultural environmental monitoring stations and other equipment and working conditions. It depends on whether the monitoring program is complete or not. The complete monitoring program mainly includes the following items: monitoring items, monitoring scope, monitoring period and monitoring points.

Soil environmental monitoring usually analyzes heavy metals, trace elements, pesticides, and other pollutants in the soil. Because the soil properties are not uniform in the spatial distribution, each sampling unit is obtained by uniformly mixing several different samples. The setting of sampling points should also take care of the overall situation of the soil as much as possible and should not be too concentrated. Sampling sites usually use grid points, diagonal points, plum-shaped points, checkerboards, and serpentine points. Sampling time is determined according to the purpose of the measurement. To understand soil contaminants'R should be collected at any time to determine the soil samples, but also to understand the pollution status of the crops grown on the soil. At the same time, the soil and plant samples should be collected during the plant harvest season.

Comparison of agricultural environmental monitoring stations and biological biological monitoring found that the use of indicator plants to monitor atmospheric pollution is an effective method. The damage caused by air pollution to sensitive indicator plants is obvious. Through a large number of experiments, a list of pollution indicators for plant pollution and a color map of pollution damage were compiled. The hazards of environmental pollution can be analyzed according to the visible symptoms of biological pollution victims. Among the three methods of agricultural environmental monitoring, the sensitivity and reliability of biological monitoring Less than physical and chemical analysis methods, therefore. It can not replace the conventional method can only make a supplement.

Crushing Machine, in a word, is a kind of machine to grind large size material or granule to smaller sizes or powder. Based on different request, Crushing machine can be divided into different types. Based on different material, different crushing machines are considered to meet different request.

For grinder large material into smaller sizes, we can use coarse crusher: This machine is a hammering type mill used to pulverize drugs, chemical materials, food staff and other materials with medium hardness and low viscosity. It is suitable for the suitable for the production in middle and small-batches or sample experiments in laboratories. Materials are fed into the pulverizing chamber by a helical conveyer, and pulverized instead of other energies of other energies of revolving parts of the machine. .
The machine is simple in structure and the pulverizing chamber can be dismounted assemble and be dismounted and cleaned easily. All the parts in the chamber which contact materials are treated specially and corrosion resistama. As a result, in addition Any material ,drifted into grind chamber through feed bucket ,punched by knife edges and knife stands ,cut and grinded simultaneously by revolving and fixed knives, and due to the centrifugal force of revolving object ,automatically runs to exit

If we grind small particles to powder: The crusher mill machine is widely used in pharmaceutical, food, chemical, it can crush various of material.

The machine is made up of feeding material part and crush part, and dust collect part. Its coniguration is very briefness, all the parts which contact the material are made of stainless steel.
