China's green food follows strict standards and principles in the use of chemical fertilizers. Green food refers to safe and high-quality edible agricultural products and related products produced in an excellent ecological environment, produced in accordance with green food standards, implemented whole-process quality control and obtained the right to use the green food label. In order to ensure the quality and safety of green food, the use of chemical fertilizers is strictly restricted and regulated.
First of all, the fertilizers used in the production of green food must be certified and licensed by the state, and comply with relevant national standards and regulations. The content of harmful substances is strictly controlled during the production process of these fertilizers to ensure that they do not cause harm to the environment and human health.
Secondly, the amount of chemical fertilizers used and the methods used in green food production are also strictly limited. Before fertilization, farmers need to formulate a scientific fertilization plan according to the soil nutrient status and crop needs. The amount of chemical fertilizer should be reasonable and not overused, so as not to cause soil pollution and crop residues exceeding the standard. At the same time, the application method of chemical fertilizer should also be scientific to avoid the loss and waste of chemical fertilizer and improve the utilization rate of chemical fertilizer.
In addition, the use of environmentally friendly fertilizers such as organic fertilizers and biological fertilizers is also encouraged in the production of green food to promote the improvement of soil ecological environment and the improvement of soil fertility. These fertilizers are not only beneficial to the growth and development of crops, but also improve soil structure, improve soil water and fertilizer retention capacity, and reduce the use of chemical fertilizers.
In addition to the use of chemical fertilizers, the use and management of other agricultural inputs are also emphasized in green food production. For example, the use of pesticides should follow the principles of safety, effectiveness and economy, and try to choose pesticides with low toxicity, low residue and environmental protection. At the same time, the use of environmentally friendly agricultural technologies such as agricultural biotechnology and physical control is also encouraged in the production of green food to reduce the dependence on chemical pesticides.
In conclusion, China's green food follows strict standards and principles in the use of chemical fertilizers to ensure the quality and safety of green food. Through scientific and rational fertilization, the use of environmentally friendly fertilizers and agricultural technology, it is not only conducive to protecting the environment and human health, but also promoting the sustainable development of agriculture.
