What is pollution-free vegetables?

What is the standard of pollution-free vegetables and pollution-free vegetables? The Chinese pesticide network Xiaobian will specifically talk about pollution-free vegetables.

The meaning of pollution-free vegetables refers to the content of harmful substances (such as pesticide residues, heavy metals, nitrites, etc.) in vegetables, which are controlled within the allowable range prescribed by the state. People do not cause harm to human health after eating. vegetables.
Broadly speaking, pollution-free vegetables should be a general term for vegetables that combine safety, quality and nutrition. Safety mainly means that vegetables do not contain substances that are toxic or harmful to the human body, or they are controlled below safety standards. Human health does not cause harm.
In a narrow sense, pollution-free vegetables refer to vegetables that are not contaminated by harmful substances. That is to say, in commercial vegetables, some toxic substances that are not allowed to be contained are not included, while some unavoidable harmful substances are controlled. Within the standard.
The basic standard of pollution-free vegetables: the difference between organic vegetables, pollution-free vegetables and green vegetables:
1. Non-polluted vegetables are safe vegetables that are produced in accordance with the corresponding production technology standards, meet the general health standards and have been identified by the relevant departments. Strictly speaking, pollution-free is a basic requirement for vegetables, and ordinary vegetables should meet this requirement.
2. Green vegetables are certified vegetables promoted by the agricultural sector in China, and are classified into two grades, A and AA. Among them, the A-grade green vegetable production allows limited use of chemical synthetic production materials, and the AA grade green vegetables are more stringent in the production process without the use of chemically synthesized fertilizers, pesticides, veterinary drugs, feed additives, food additives and other harmful to the environment and Healthy substance. In essence, green vegetables are a transitional product from ordinary vegetables to organic vegetables.
3. Organic vegetables refer to agricultural and sideline products and processed products that are produced and processed in an organic manner and that meet relevant standards and have been certified by a special certification body.
The pollution-free vegetables specifically need to be "three not exceeding the standard":
1. Pesticide residues do not exceed the standard and cannot contain prohibited high-toxic pesticides. Other pesticide residues do not exceed the allowable amount;
2. The nitrate content does not exceed the standard, and the nitrate content in the edible vegetables does not exceed the standard allowable amount;
3. The harmful substances such as “three wastes” do not exceed the standard, and the content of harmful substances such as “three wastes” and pathogenic microorganisms of pollution-free vegetables does not exceed the prescribed allowable amount. Quality - mainly refers to the quality of the goods. The individual is neat, the development is normal, the maturity is good, the texture tastes good, the fresh disease-free pests are harmed, and the clean vegetables are listed. Nutrition - refers to the inherent quality of vegetables.
Production technology of pollution-free vegetables In the production of vegetables, we should implement the guidelines of “prevention first, comprehensive prevention”, establish a production base without pollution sources, and follow the following ten technical points:
1. It is strictly forbidden to apply highly toxic and highly residual pesticides, such as 3911, 1605, carbofuran and so on.
2. Select high-efficiency, low-toxic, low-residue pesticides with low lethality to natural enemies of pests, such as phoxim and carbendazim.
3. Vegetable bases should be kept away from industrial and mining pollution sources and avoid “three wastes” pollution.
4. Choose disease-resistant, insect-resistant, high-quality and high-yield varieties.
5. Deep ploughing, changing crops, adjusting temperature and humidity, and cultivating a good ecological environment.
6. Promote the application of microbial pesticides.
7. Do a good job in predicting and forecasting pests and diseases, and use the right amount of drugs at the right time.
8. Promote physical control methods that do not cause pollution, such as soaking seeds in warm soup, suffocating in high temperature, grafting of black seed pumpkin, etc.
9. Do a good job of formula fertilization, control the amount of nitrogen fertilizer, and promote the application of enzymes such as enzyme bacteria, K100 and other active organic fertilizers.
10. Do a good job in plant quarantine. Strictly prevent the spread of devastating diseases such as cucumber scab and tomato ulcer disease.
