Agricultural Environmental Monitoring Station Analysis of Agricultural Environment
With the rapid development of industrial and agricultural production in our city, industrial, urban "three wastes," (wastewater, waste gas, waste residue) and the use of a large number of agricultural chemicals have brought increasingly serious impact on the agricultural production environment, mainly in the following aspects: The city is located in the coastal area of ​​the North China Plain, with high groundwater level, high degree of mineralization, salty alkalinity in the soil, shortage of water resources, large area of ​​sewage irrigation, reduced application of organic fertilizer in recent years, and relative lack of soil organic matter. In addition, the rainfall was uneven throughout the year, and spring drought and summer leakage occurred, resulting in a decline in the quality of cultivated land in our city.The agricultural environmental monitoring station conducted monitoring and analysis of the environmental conditions of agricultural production to provide basis for the formulation of relevant production measures.

The determination of agricultural environmental monitoring stations found that excessive application of nitrogen fertilizer not only wastes fertilizer but also accumulates nitrate and nitrite in vegetables. If it exceeds the standard, it is easy to form nitrosamine carcinogens in the human body and should be highly valued. The use of pesticides is one of the effective measures for controlling pests and diseases of crops. However, the use of highly toxic pesticides on vegetables currently violates the “Pesticide Safe Use Regulationsâ€. This will pose a serious threat to people’s lives. Plastic film mulching techniques have been widely applied, but the broken mulch remains in the soil each year, which will reduce crop production.
At present, the deterioration of the agricultural environment and the reduction of resources in our city are becoming more and more serious. Over time, this will affect the sustainable development of the agricultural economy in Tianjin. Effective and effective measures must be taken to control and use natural resources rationally to prevent environmental pollution and ecological damage.
The use of agricultural environmental monitoring stations found that environmental monitoring is the sentinel and the eyes and ears of environmental protection. It is one of the important means of doing a good job in agricultural environmental protection. Therefore, regular fixed-point monitoring of agricultural environment and monitoring of pollution sources must be carried out to keep abreast of the pollution degree and development and change laws of soil, agricultural water, and quality of agricultural products. Effective and effective prevention and control measures must be taken to reduce the impact on the agricultural environment. Economic losses caused by pollution.
