What kind of chemical fertilizers are suitable for green food in China?
Introduction. While the material life of the people is constantly improving, higher requirements are also put forward for food safety and environmental protection. "Green food" is an environmentally friendly, healthy and safe food. The development of China's "green food" is a key point in the strategy of realizing the sustainable development of China's agriculture. Through the analysis of the definition, development process, current situation and development trend of the concept of "green food" in China, the development direction of "green food" in China is proposed.
1. The concept and characteristics of "green food".
"Green Food" is certified as "Green Food" through a special production process, certified by a professional department, and certified as "Green Food". Its characteristics are as follows:
1.Ecological: In the manufacture of green food, the amount of inputs such as chemical fertilizers and pesticides is strictly controlled to reduce the impact on the environment, so as to achieve the protection of the ecological environment.
2.Safety: The product adopts high-quality products in the processing process to ensure the safety of the product and the protection of the human body.
3.High quality: In the process of production, breeding and processing, the product quality is strictly controlled to ensure the nutrition and taste of the food.
Second, the development process of China's "green food".
Since the early nineties, China has gone through the following steps:
1.In the early 90s, China introduced the concept of "green food", and through experimentation and experimentation, the development of "green food" was gradually promoted.
2.Rapid development period: After the 21st century, China's green food industry has developed rapidly, the variety and scale of its products are growing, and the market share in China is gradually increasing.
3.Standardized development period: In recent years, China has implemented standardized management of China's green food industry, issued a set of relevant laws and regulations, strengthened its supervision, and promoted the healthy development of China's green food industry.
Third, the situation and existing problems of chemical fertilizer application in China.
Fertilizer is the main component of agriculture and an important guarantee for increasing grain production. However, the application of fertilizers also has the following problems:
1.Improper application: In order to achieve high yields, some farmers apply a large amount of chemical fertilizers in production, resulting in a series of problems such as soil pollution and eutrophication of water bodies.
2.Single application: Some farmers apply a single fertilizer for a long time, which causes damage to soil structure and soil fertility, which has an adverse impact on the growth and quality of crops.
3.Light application of organic fertilizer: Some farmers are overly dependent on fertilizer, and light application of organic fertilizer has caused soil nutrient imbalance and seriously restricted the production and quality of food.
Fourth, the application strategy of fertilizers in China.
In China, in order to promote the development of "green food", a number of strategies have been adopted in the application of fertilizers:
1.Vigorously promote soil testing and formula fertilization: Formulate appropriate fertilization plans based on local nutritional conditions and crop needs, so as to reduce the amount of nitrogen fertilizer application and increase the efficiency of nitrogen fertilizer use.
2.Promotion of organic fertilizers: The state has formulated a series of measures to enhance soil fertility, improve soil, promote crop growth and development, and improve product quality.
3.Vigorously promote new fertilizers: develop and promote new fertilizers that are efficient, environmentally friendly and safe, such as slow-release fertilizers and biological fertilizers, to reduce pollution to the ecological environment.
5. Prospects. 
In China, due to the increasing public awareness of food safety and environmental protection, it has good development potential. In the future development of China's green food industry, there will be the following development trends:
1.The market space for products is getting bigger and bigger: due to people's higher and higher requirements for green food, China's green food market will continue to grow in the future.
2.Continuous improvement of quality requirements: People have put forward higher requirements for the quality of green food, therefore, the green food industry must continue to improve to meet the needs of customers.
3.The industrial chain continues to improve: it will make China's industrial chain more sound, make production, processing and sales more closely linked, and enhance the comprehensive competitiveness of the entire industry.
4.The internationalization level of Chinese products has improved: in today's deepening process of economic integration, China's green products will be more active in the international market and have a greater voice in the international market.
Conclusion. The development of China's "green food" is related to national food security and sustainable agricultural development. In the application of fertilizers, China has adopted a series of measures to reduce the impact of fertilizers on the ecological environment, so as to achieve the purpose of increasing production and efficiency. In the future, China's "green food" will play an increasingly important role in ensuring people's health and sustainable agricultural development.
