Introduction
With the improvement of people's living standards, food safety and environmental protection issues have attracted more and more attention. As an environmentally friendly, healthy and safe food, green food is more and more favored by people. In China, the development of green food has become an important direction for the sustainable development of agriculture. In this paper, the definition, development history, current situation and prospect of chemical fertilizer use in China will be summarized, in order to provide reference for the development of green food.
1. Definition and characteristics of green food
Green food refers to the pollution-free safe, high-quality and nutritious food produced in accordance with a specific production method, recognized by a specialized agency, and licensed to use the green food mark trademark. It has the following characteristics:
1.Environmental protection: The use of chemical fertilizers, pesticides and other inputs is strictly controlled in the production process of green food to reduce pollution to the environment and protect the ecological environment.
2.Safety: The production of green food follows strict quality standards to ensure the safety of food and protect the health of consumers.
3.High quality: Green food pays attention to quality in planting, breeding, processing and other links to ensure the nutritional value and taste of food.
Second, the development process of China's green food
The development of green food in China began in the early 90s of the 20th century and has gone through the following stages:
1.Initial stage: In the early 90s of the 20th century, China began to introduce the concept of green food, conduct pilot demonstrations, and gradually promote the production of green food.
2.Rapid development stage: After entering the 21st century, China's green food industry has developed rapidly, the types and quantities of green food have been increasing, and the market share has gradually expanded.
3.Standardized development stage: In recent years, China has standardized the management of the green food industry, formulated a series of regulations and standards, strengthened the supervision of green food, and promoted the healthy development of the green food industry.
3. Current situation and problems of chemical fertilizer use
Chemical fertilizers play an important role in agricultural production and provide a strong guarantee for increasing crop yields. However, there are also some problems in the use of fertilizers:
1.Overuse: In pursuit of high yields, some farmers blindly increase the amount of chemical fertilizers, leading to environmental problems such as soil pollution and eutrophication of water bodies.
2.Single use: Some farmers use chemical fertilizers for a long time, resulting in the destruction of soil structure and the decline of fertility, affecting the growth and quality of crops.
3.Neglect of organic fertilizers: Some farmers rely too much on chemical fertilizers and neglect the use of organic fertilizers, resulting in an imbalance of soil nutrients and affecting the yield and quality of crops.
4. Fertilizer use strategies for green food in China
In order to promote the development of green food, China has adopted a series of strategies for the use of chemical fertilizers:
1.Promote soil testing and formula fertilization technology: according to soil nutrient status and crop demand, formulate a reasonable fertilization plan, reduce the amount of chemical fertilizer, and improve fertilizer utilization rate.
2.Encourage the use of organic fertilizer: ** Introduce policies to encourage farmers to use organic fertilizer, improve soil fertility, improve soil structure, and promote the growth and quality of crops.
3.Promote new fertilizers: research and development and promotion of new fertilizers with high efficiency, environmental protection, safety and other characteristics, such as slow-release fertilizer, biological fertilizer, etc., to reduce the pollution of chemical fertilizers to the environment.
Fifth, the prospects
With people's increasing attention to food safety and environmental protection issues, the development of green food in China has broad prospects. In the future, China's green food industry will continue to maintain a rapid development momentum, showing the following trends:
1.Expanding market size: The market size of green food will continue to expand as consumer demand for green food continues to increase.
2.Continuous improvement of quality requirements: Consumers' quality requirements for green food will be higher and higher, and the green food industry needs to continuously improve product quality to meet the needs of consumers.
3.The industrial chain will continue to improve: the green food industry will further improve the industrial chain, realize the organic connection of production, processing, sales and other links, and improve the overall competitiveness of the industry.
4.Increasing degree of internationalization: With the in-depth development of globalization, China's green food will actively participate in international competition and enhance its international influence.
Conclusion
The development of green food in China is of great significance to ensure food safety and promote the sustainable development of agriculture. In terms of fertilizer use, China has adopted a series of strategies to reduce the pollution of chemical fertilizers to the environment and improve the yield and quality of crops. In the future, with the continuous development and growth of the green food industry, we have reason to believe that China's green food will play a more important role in ensuring people's health and promoting the sustainable development of agriculture.
