Grandpa is still irrigating in the traditional way

Can farmers eat vegetables watered with manure? With the rapid development of society, people's lives are getting better and better. With money, people nowadays pay great attention to health preservation. Especially, some exquisite people in the city will choose some green, clean and pollution-free vegetables and fruits to ensure their health. It is true that such a choice is naturally good. After all, the disease comes from the mouth. Among all kinds of vegetables, no one can guarantee that the vegetables he bought are absolutely clean.

However, there are still some city people who go to extremes when buying food. They think that vegetables with pesticide residues can't be bought, and vegetables watered with manure water should not be bought. Only vegetables irrigated with mountain spring water can be eaten. Having said that, the author is also very puzzled. It is understandable that vegetables with drug residues cannot be bought, because drug residues are not good for people. But for some city people, vegetables watered with this kind of dung water are inedible, so the question is, are vegetables watered with this kind of dung water really inedible? Plum as a rural people, to answer this question:

As for whether the vegetables watered with manure can be eaten, let me first talk about the embarrassing thing of growing vegetables and delivering them to rural neighbors:

My neighbor's uncle grows some vegetables in the garden, such as cabbage, spinach, radish, pumpkin and so on. In order to make vegetables grow bigger and fatter, he goes to the garden every morning to irrigate with urine and manure and topdressing.

In this way, the vegetables in the garden grow better and better under the careful management of the uncle, and the output seems to be much more than other people's vegetables. After collecting so many dishes, my uncle carefully selected some and gave them to the son of the provincial capital by car.

After seeing such big pumpkins and cabbages, the daughter-in-law in the city also wondered why the vegetables in her rural hometown were so big. The uncle proudly said: this dish is irrigated with manure every day, and there is no pesticide residue. People in the city generally don't eat it.

The daughter-in-law's face sank at that time. After the father-in-law left, he began to blame her husband, saying: this manure is dirty and smelly, and it contains a lot of bacteria and parasites. How can you water the vegetables like this? Can you eat the vegetables? Throw it away quickly, because neither I nor the children will eat it anyway. The husband is also a "wife's inflammation", so he had to secretly give these dishes to people, and repeatedly told his father in the countryside that he would not bring any "dishes watered with manure" when he came.

The story of uncle growing vegetables and delivering vegetables is over. Is the daughter-in-law of this city right? Is this vegetable watered with manure really inedible? Plums are considered edible for several reasons:

First, irrigating vegetables with manure is the wisdom and experience left by our ancestors. All ancestors can eat, and naturally we can eat.

Before the emergence of chemical fertilizer, when our ancestors planted vegetables, they all watered them with manure in order to make them fatter and bigger. This practice lasted for hundreds or even thousands of years. When the ancestors planted vegetables, there were also many proverbs, such as this sentence: If you want to be delicious, you can't leave the dirt ","When you pour the radish and onion together, the cucumber next to it will grow wildly "and so on.

And these manure, which is what we often call fertilizer, plays a great role in vegetable growth. If manure is used in the field for a long time, the vegetables and crops in the field are always surprisingly good, much better than some fertilizers. Therefore, some rural farmers prefer to spend high prices and buy some manure to promote the rapid growth of vegetables.

And then irrigated with manure, where did the vegetables grow? Of course, they were eaten by our ancestors. Then, since our ancestors could eat such vegetables, what's wrong with us modern people? What can't we eat?

Secondly, manure is not directly used to irrigate vegetables, but is used to fertilize after farmers ferment and decompose, and the fermented manure has already been sterilized and is safe for vegetables.

Experienced farmers have a trick when farming, that is, first pile some manure, then cover it with plastic sheets, and sprinkle soil on it for fermentation and decomposition. After one to two months of fermentation, some harmful bacteria and parasites in the fecal water were killed and transformed into humus beneficial to the soil. Therefore, this fermented manure is applied to the fields by farmers for the growth of crops, which is beneficial to the growth of vegetables and people's health. This is much better than applying fertilizer to vegetables.

Therefore, when farmers grow vegetables, they also disinfect manure and then irrigate it to the roots of vegetables, so that these manure and organic fertilizer can flow to the ground and be fully absorbed by the roots of vegetables, thus becoming the nutrients needed for vegetable growth. Therefore, it is safe for farmers to fertilize vegetables instead of directly irrigating crops, so we don't have to be afraid of bacteria in manure when eating vegetables.

Third, the manure water will not directly contact the vegetable leaves, but will be irrigated at the roots of the vegetables, so the vegetables are at least clean and will not contact the vegetable leaves.

Some city people may have misunderstandings about topdressing vegetables. They think that manure is directly sprinkled on the leaves of vegetables. But I don't think so, because vegetables, like trees, grow through root absorption, not through leaves. Therefore, when farmers use manure, they also irrigate their roots to make vegetables grow faster.

For example, farmers always use this manure to irrigate their roots when topdressing vegetables such as cabbage, spinach and kidney beans, but the leaves and fruits we eat are not polluted at all. If farmers pour manure on the leaves, because the leaves are tender, within a few days, the leaves will be "burned" by manure, resulting in reduced vegetable production, which is not worth the loss for farmers. Therefore, watering vegetables with manure water will not cause too much harm to vegetables, and we can eat them normally.

To sum up: from the above, we also thoroughly understand the fertilization and irrigation methods of manure, and the harm of manure to vegetables and people. Therefore, this kind of manure belongs to the category of organic fertilizer, which is much more organic and green than any chemical fertilizer. If someone is still worried that vegetables treated with manure can't be eaten, don't buy them. Just get a vegetable garden, grow it yourself, and put nothing away.

There is an old saying in the countryside: "No dung stinks, no five grains smell"! Therefore, after fermentation and sterilization, manure is a kind of high-quality fertilizer, which decomposes in soil, increases organic matter and improves soil fertility, and then is purified by sun and rain without pollution. On the contrary, in the absence of manure, only relying on chemical fertilizers is not good for the soil, and there is no smell of manure topdressing crops. So this manure is naturally a good farmyard manure. Our ancestors used and ate vegetables for thousands of years. It has become a question here!
