Farmers will add some salt when spraying, what is the reason?

Most of the people who do this are the result of being uneducated and illiterate. In our village, there is such a thing: to apply fertilizer to garlic, we used to use small packets of potassium dihydrogen phosphate, and the packaging of this fertilizer is the same as salt.

The man was busy with a meeting, asked his wife to water the ground and make fertilizer, and used salt as fertilizer, and made a mistake in fertilization, I believe what you said. Many years ago, someone in my village once sprinkled a bag of cement on the ground as phosphate fertilizer and made a joke. The 50 catties of salt you said, on 2 and a half acres of land, the amount is not very much, it must have an impact on the crops, but the impact is not, 50 catties of salt are sprinkled with chemical fertilizer in the mu wheat field, how careless is this?

Salt is inseparable from three meals a day, and it is often seen. Even if you don't know about chemical fertilizers, you should know about salt. Besides, most of what people eat today is refined salt, and almost all chemical fertilizers are known.

Since it was sprinkled by mistake, the amount is not large. It's all about sterilizing the wheat. It is estimated that it will have little impact on wheat, so don't worry.

If you are worried, you can sprinkle an appropriate amount of potassium dihydrogen phosphate fertilizer and sodium chloride (salt) to neutralize and neutralize, won't it be solved?

<> is not afraid of being tired of watering and diluting salt A high school chemistry teacher said that sprinkling salt into the ground can increase yield, and sodium ions replace potassium ions, which is equivalent to applying potassium fertilizer, waiting for a bumper harvest. In the old society, the poor rented the landlord's land to cultivate, and in the last year they sprinkled salt, and in the year they produced a good harvest, and the next year the land fertility declined. I'm not a farmer, and I'm not as experts say it :

Inch wheat eats zhang water, wheat eats three zhang water, and eats two zhang in February. In the above situation, the most effective way is to pour water into the ground as soon as possible, so that the salt is released and precipitated at the bottom of the soil, and it can be irrigated once every 7 days, which can be irrigated three times in a row, which can keep the wheat unharmed.

As a farmer who only grows wheat per acre, there is not much land, and when such a farmer starts to buy fertilizer, he plans how much base fertilizer and how much top dressing, how can he use salt as fertilizer? Then the teacher may be saying that if the salt is used as top dressing?

Because they think that diluting edible salt to water crops can play a role in increasing yields, but in fact, there is no scientific basis for this practice, and adding salt will not increase yields, but waste costs, which is a superstitious practice.

Agricultural experts went on to say that salt is a condiment, the main ingredient of which is sodium chloride, and salt is an ionic compound. In our country, people have been eating salt for a long time. Salt-making utensils have been found in artifacts excavated in Fujian, which were identified as commonly used utensils in the Yangshao period.

In our country, the history of people eating salt can be proved to be 5,000 years ago. The main component of salt is sodium chloride, which can be used industrially to make soda ash, caustic soda and other chemical products, so sodium chloride is still widely used.

But excess sodium chloride is very bad for the growth of plants. A research institute in Fuzhou, Fujian Province, said that sodium chloride will cause water stress and ion stress to salt-intolerant plants, and if a certain amount of sodium chloride is absorbed by salt-intolerant plants, salt-intolerant plants are prone to cell dehydration and ionic imbalance in the body, while salt-intolerant plants will cause yellowing, wilting, and falling off leaves, and flowers cannot bloom normally. The absorption of sodium chloride by non-salt-tolerant plants in large quantities will lead to plant death, so sodium chloride is still very harmful to salt-tolerant plants, and many farmers grow food crops that are salt-tolerant plants.

Facial cleansing is a commonly used cleansing product in daily life. The main ingredients of detergents are sodium alkyl sulfonate, sodium sulfate in fatty alcohol, foaming agents, solubilizers, flavors, water, pigments, preservatives, etc. Sodium alkyl sulfonate and sodium fatty alcohol ether sulfate are anionic surfactants, which are petrochemical products that can be used to remove oil stains.

The reason why salt can control weeds is because chloride ions and low-concentration salt solutions are not as effective as some weeds, and they are actually used in high concentrations. This leads to crop penetration, wrinkle of crop protoplasm, and plasma wall separation. That is, we see that the leaves turn yellow and the phenomenon of "flower shape" appears.

This is also a potential danger to crops.

The main components of detergent are sodium alkyl sulfonate, sodium fatty alcohol ether sulfate, foaming agent, etc. They are all petrochemical products, which can remove pollution and are good helpers for families, but because they are chemical elements, they reach the human body and animal bodies through the food chain after trial, endangering the health of humans and animals, and causing a variety of diseases. In addition, it will also affect the growth and yield of plants.

Because detergents are alkaline, they can cause alkalinization of the soil. Make crops low or unable to grow, there is a series of plant growth disorders (such as yellowing, dwarf, leaf fall, leaf curl, etc.), some people like to water the flowers with detergent solution every day, if the concentration can not be adjusted, the flowers will soon turn yellow.

It doesn't meet it, because pesticides still have the effect of weeding, and adding salt is useless, so it should be unscientific.

Of course, it's not scientific, many years ago, the efficacy of herbicides was very low, at that time, many people mixed herbicides and laundry detergents together, and now the efficacy of herbicides and other herbicides has reached 68%, and some have reached 88%, so there is no need to add anything else, unless it is a herbicide that is matched with him, it can be used together, and adding salt alone is not necessary and has no effect.

This method is in line with scientific farming, because salt not only has a bactericidal effect, but also balances the minerals in the soil and provides sufficient nutrients to plants.

Why do people add salt to herbs when adding herbs to crops? When the prevention of crop pests and diseases and **, a little vegetable oil or mineral oil or sugar or sugar or washing powder, salt, etc., can significantly improve the efficacy and enhance the control effect.

Sulfide binder is a common special effect that controls fruit trees, white powder, wheel disease, pear rust disease, flowers, rust and many mites, but the effect is not ideal, especially alone. Prevention and ** of citrus red spider were 87, 85, and 39 after the first, 2nd, and 7th week, respectively.

During the first, 2nd and 7th weeks, the salt and salt in the laundry detergent and graphitate can be added to 99 -100. The practice is to add laundry detergent and salt salt to the sulfoxide sulfide hyalineaemia and mix after mixing. Dissolve the laundry completely before use and mix with the limeamide mixture.

The front and back of the blade should be sprayed when spraying, and the effect is very effective. There is no scientific basis for salt to increase soil alkalinity rather than growing crops.

If you don't have to lift the salt salt, it's not long, estimated at a few thousand pieces of salt.

The least willing to spend too much effort on the herbicide, what type of herbicide type to use. If you are willing to ventilate, use physical methods such as grass, earth grip, etc., although it is good, the improved soil works better. Special saline or cohesive or sandy soils for improved results.

It is necessary to explore and practice under the guidance of technology and theory, and not act blindly.

Because the amount of electrolyte ions containing electrolyte ions is too high, the osmotic pressure of the soil causes the roots of the plant, but the water is "squeezed", causing the plant to dehydrate. The principle of tissue and salt, it will die is the same physical principle. This is also the reason why plant fertilization causes burns to seedlings because the fertilizer is salt.

If the grass wakes up on the ground, the grass dies and his crop disappears, so it's a non-still life method!

This is because when spraying crops, adding a small amount of salt, or washing powder, mineral oil, etc., can play a good role in improving the efficacy and enhancing the control effect. But you can't add too much salt, too much salt will burn the plant, so just in moderation.

Mainly because of the choice of adding salt, it is also to be able to carry out a series of protection on crops and avoid a series of damage to crops caused by pesticides, so it can be said that it is also very advanced, and this decision was made after a series of studies.

It is because it can be sterilized and disinfected, and it is also the most commonly used method, and the cost is relatively low.

Because doing so, there are some benefits for the crops, which allows them to absorb water more and the roots will crawl deeper. Grow stronger.
