Pollution-free planting, closed management and effective pest control have long been put on the agenda. Vegetable cultivation has strengthened field management, and the variety, taste and seasonal vegetables of vegetables are readily available. Energy-saving greenhouses and soilless culture are also developing rapidly. The cost of taking medicine will increase, and the rent in the city will be more expensive. The bagged Flammulina velutipes and mushrooms I bought last time were taken home as potions. The smell was so bad that I dared not eat them and threw them away. Therefore, when consumers buy it, the price will be more expensive than that of grandparents selling vegetables in rural areas.

If there is a certain application interval, the pesticide residue in vegetables is still very low (within the allowable range) and can be safely eaten. Farmers' awareness of quality and safety has also improved. Vegetables can basically be eaten safely without using highly toxic pesticides and keeping the application interval. Most of them are supplied by professional vegetable planting bases. In order to produce higher benefits, more pesticides, fertilizers or ripening agents will be used in the growth of vegetables. On the contrary, fertilizers and pesticides are rarely used in rural vegetables. From a health point of view, vegetables in rural areas are naturally good.

Both plants and animals are limited by climate change. Only by keeping in line with the four seasons can we live a long and healthy life. On the contrary, it will be affected by heaven and earth and get sick. In diet, of course, we should also follow the principle of time and tide wait for no man, and we should not violate the principle of keeping healthy in the four seasons because of the pursuit of appetite. "Although the dishes in the supermarket are bright and beautiful, many of them are planted in greenhouses, and there will be problems such as excessive hormones, such as some cucumbers with pedicels and tomatoes with red growth promoters, which are also related to the quality of growers. Generally speaking, rural areas still eat their own vegetables.

Fertilizer and auxin are used, everyone has eaten rattan vegetables, and the north is called water spinach. They use auxin immediately after harvesting crops. None of the vegetables bought in the market have been tested for drug residues, and I don't know when he used pesticides. Relatively speaking, I think farm vegetables and safely cooked vegetables have a sweet smell. I live in Shenzhen and occasionally buy beets, but I seldom meet them. Some people may say, buy organic vegetables.
