Grandma said that many dishes in the vegetable market can't be eaten now. They look glamorous and attractive on the surface, and they have no taste in their mouths, which is no different from chewing grass. Some vegetables are treated with pesticides from the seedling stage until they blossom and bear fruit, and are eaten up by insects before they are mature.
I have a deep understanding of what grandma said. As a child growing up in the countryside, I am familiar with the vegetables that are often grown in the garden. Especially for insects-prone vegetables, every time you pick vegetables, you find that big and fat insects will throw them far away. If you don't choose carefully, you may suddenly meet one in your mouth while eating.
So which dishes often need pesticides?
First, cowpea. I can eat two bowls of rice on a plate of dry stir-fried green cowpea, but I can't do without pesticides. Pesticides should be applied when flowering to prevent aphids from biting off stamens. Pesticides should be used at the fruit-bearing stage, otherwise the young fruit will be bitten quickly. If you want to use pesticides at maturity, bugs will get into cowpeas, and this season's hard work will be in vain! When I was a child, there were many children at home. After school, I was called to catch bugs in the vegetable garden. At that time, vegetables were really green and pollution-free. Even catching insects is manual work, which is safe to eat.
Second, vegetables. What is included in this is quite common: most green leafy vegetables, such as Chinese cabbage, small green vegetables and Chinese cabbage, have been caught by these vegetables for several hours. The most impressive thing is cabbage, and some of them are also called cabbage. Because its growing season is just in spring, the eggs that have gone through a winter begin to hatch into larvae with the increase of temperature. After a few days, only the stem and stem of a cabbage can be bitten by insects. In rural areas, not many people grow this dish, because it is too easy to get insects. It takes time and effort to catch insects manually, and pesticides are not good for your health, so simply don't grow this dish.
Thirdly, cucumbers, eggplants and green peppers can also be used as pesticides. This kind of vegetables is related to leafy vegetables, and the frequency of application is low, so it is enough to apply 1-2 times at seedling stage and fruiting stage. The purpose of applying pesticide at seedling stage is to avoid aphids and some physiological diseases caused by climate, soil and other problems, and the purpose of applying pesticide at fruiting stage is to prevent fruits from being eaten by insects and damaged. After each application, it takes at least half a month to eat these fruits and vegetables until the pesticides are completely dissolved and volatilized, otherwise it may cause harm to the body shape.
Fourth, mushrooms, mushrooms and other fungi will also use pesticides. In the early stage, pesticides will be used to disinfect the substrate, and there will be pests and diseases in the later growth process, so some fungi will use hormones to accelerate the maturity and listing of fungi during the growth period. After buying home, these vegetables must be soaked in salt water for a certain period of time before they can be eaten to reduce pesticide residues.
These vegetables are often treated with pesticides, so I seldom buy them in the vegetable market, but I often buy vegetables grown by old people and old ladies on the roadside.
Let's talk about vegetables that are often treated with pesticides, and then talk about which vegetables are rarely or even basically treated with pesticides.
1. Seasoned vegetables, such as scallions, shallots, ginger and garlic sprouts, are the most common vegetables in rural gardens, and pesticides are rarely used. From sowing to harvesting, as long as they have enough water and fertilizer to grow, they will have a good harvest in the end. Because these dishes have a particularly pungent taste, it hurts to bite. Insects are sensitive to this taste, so they don't bother themselves and try to stay away from these dishes.
Second, lettuce, lettuce, oily wheat, leek and other vegetables rarely use pesticides. Like the onion, ginger and garlic above, these vegetables also contain special flavors such as lettuce and erucic acid, which are very bitter to eat. Insects will do harm to themselves after eating them, so they won't like these vegetables. This is also the reason why these vegetables we saw in the garden are growing well and there are few pests and diseases.
Three, potatoes, potato, radish, lotus root, yam and other root vegetables, rarely use pesticides. Because these vegetables grow in the air, the relationship between pests in the soil and the air is much smaller, and most of the open insects are crickets, needle worms and so on. The method of killing these insects is much more complicated than spraying pesticides. Unless large-scale planting bases take measures to prevent them, ordinary gardens are rarely managed. These dishes bitten by insects are just unsightly in appearance and do not affect eating.
Fourth, spinach, coriander, celery, etc. Due to seasonal reasons, pests and diseases rarely occur, so pesticides are not used. Spinach and celery, these vegetables, should be the least likely to use pesticides. Because it belongs to winter vegetables, which are sown in late autumn and harvested in winter, and most insects have entered hibernation in low temperature and snowy weather, there is no need to worry about pests and diseases, so vegetables at this time are the safest to eat.
The above vegetables contain little or no pesticides, so we can pay more attention to the vegetable market and try to choose seasonal vegetables. Here are some tips for buying vegetables, so that we can buy truly green and pollution-free vegetables when buying vegetables.
First, peeled potatoes, yams and washed lotus roots are best bought less. Although these dishes can save us time in peeling and cleaning, they are not necessarily safe! Especially the peeled potatoes and washed lotus roots look really beautiful, but many of them are soaked with drugs in order to sell them at a good price. I have personally experimented with buying lotus roots, washing them and leaving them overnight. The color turned black the next morning, and it was almost impossible for lotus roots in the market to remain white and tender for several days. Try to buy land with skin and soil, and I will start liquidation when I come back. Although it is troublesome, I can rest assured.
Second, when buying green vegetables (all vegetables with leaves), try to choose the ones with wormholes on them. This common sense is known to many people. Insect eyes prove that there are traces of insects crawling, at least pesticides are used less or the harm of pesticides is not so strong, and eating them is not very harmful to the body.
Third, try to choose seasonal vegetables, not only because they taste better, but also because of less pesticide residues and cheap prices. Ordinary out-of-season vegetables are planted in greenhouses, which are highly dependent on labor and technology, and also increase the planting cost. The high price when ordinary people buy is the reason. Seasonal vegetables are cheap and delicious, and vegetables grown according to natural laws are also the first choice for ordinary people.
With the continuous progress of science and technology, more and more organic vegetables appear on people's dining tables. Although expensive, compared with its health benefits, it has become the choice of high-income families in many big cities.
Ordinary people can't have a better choice like the high-income class, but we can do enough work in cleaning and disinfection, and there are many vegetable and fruit cleaning agents on the market to remove pesticide residues, so it's okay for us to spend more time on cleaning. what do you think?
