Spunbond Nonwoven Production Line The polyester PET non-woven production line is used for the production of non-woven fabrics such as polypropylene spinning, web forming, and hot rolling reinforcement. Using polypropylene as the main raw material, supplemented by color masterbatch, anti-oxidation, anti-pilling, flame retardant and other auxiliary agents, it produces PP spunbond hot-rolled non-woven fabrics with different colors, properties and uses, and polyester spunbond and hot-rolled non-woven fabrics. It has the excellent characteristics of high strength, low shrinkage, heat resistance, good stability, breathable waterproof, flame retardant, acid and alkali resistance, moth-proof, non-toxic and anti-ultraviolet.

Long-term excessive application of chemical fertilizers or improper application can cause significant environmental pollution or potential pollution. Except for the long-term single application of chemical fertilizers, soil degradation due to the lack of timely supplement of organic matter and reduced soil productivity, the nitrogen and phosphorus elements in chemical fertilizers will also cause eutrophication of the water bodies, resulting in the massive breeding of algae and other aquatic organisms, leading to shortages. Oxygen and anaerobic decomposition, so that fish lose their living conditions. This results in the accumulation of nitrates in food, feed and drinking water and endangers the health of people and livestock. At the same time, the decomposition of nitrogen fertilizer not only pollutes the atmosphere. When the nitrogen oxide produced rises to the stratosphere, it also has a destructive effect on the ozone layer. In addition, agricultural wastes with high nitrogen content, such as livestock manure, farmland orchard residues, and agricultural product processing waste, can also cause eutrophication of water bodies and endanger fish and various aquatic organisms.
Some long-acting pesticides, such as DDT, HCH, etc., are chemically stable and are not easily decomposed by the action of acids, phosphorus, oxygen, and ultraviolet rays, and have strong fat-soluble and low water solubility. Absorbed, resulting in residues in crops, pesticides that have landed on the ground, and some remain in the soil, are ingested by soil animals such as earthworms, accumulated and concentrated in their bodies, and are damaged by predation by poultry, etc.; With irrigation water or rainwater flowing into the rivers, lakes and seas, through the transmission of aquatic animal chains, they are concentrated in the fish body by thousands, tens of thousands or even millions of times, causing harm. In addition, the long-term use of pesticides will also increase pest and disease damage due to the elimination of natural enemies of pests and resistance to pests and pathogenic microorganisms.
The use of agro-environmental recorders to further strengthen the monitoring of the agricultural environment, the purpose of which is to quickly grasp the current status and trends of agricultural environmental pollution, provide forecasting data, so as to take appropriate measures as soon as possible to prevent pollution material hazards, and to provide scientific long-term strategies in accordance with. The monitoring content focuses on the important pollutants that endanger the agricultural environment. In case of emergency, specific items can be monitored.
The agricultural environment is the natural environment on which all types of agricultural organisms rely, including farmland soil, water, air, daylight temperatures, and so on. However, some people's long-term activities rarely protect the environment, which leads to deterioration of the quality of the agricultural environment and hinders the growth of the organism. Therefore, the protection and rational use of agricultural natural resources are issues that must be addressed in order to prevent environmental pollution and protect agricultural ecology. Even the use of fertilizers and pesticides requires strict controls. Agricultural environment recorders can accurately measure conditions such as temperature, humidity and light in agriculture, and provide scientific data for the construction of refined agriculture.
