What should I do if cabbage vinegar spraying fails? What is the effect of spraying white vinegar wit

When spraying vinegar with cabbage, in the process of spraying, the number of sprays is too large, and the amount is too large, which will cause adverse consequences. When the cabbage is sprayed with vinegar too many times and the amount is too large, the leaf surface of the cabbage will appear uneven, the leaf surface will not be smooth, and the local cells will shrink and shrink seriously, and even turn yellow. Therefore, when using edible vinegar to spray cabbage, it is necessary to control the number of sprays and the concentration of adaptation.

In general, cabbage can be sprayed once every 20 to 30 days, and it will not have too much impact on cabbage.

Spraying edible vinegar on cabbage has a very great effect on the growth and development of cabbage, which can improve the quality of cabbage, increase yield, and prevent pests and diseases.

First, spraying vinegar on cabbage can increase the yield of cabbage. Edible vinegar is made from grain by fermentation. The inside of edible vinegar is rich in protein and amino acids.

Organic acids, minerals.

and so on. These substances are sprayed on the leaf surface of cabbage, and after being absorbed and utilized by the foliage, they can promote the growth of cabbage and have the effect of increasing the yield of cabbage. Farmers have done comparative experiments, under the same planting conditions, the yield of cabbage without spraying vinegar is fundamentally different from the yield of spraying vinegar cabbage.

Under normal circumstances, cabbage sprayed with edible vinegar can increase the yield by about 20%. ～～

Second, when cabbage is sprayed with edible vinegar, the quality of cabbage can be improved. Edible vinegar is rich in protein and some organic acids, amino acids, minerals and other nutrients, sprayed on cabbage leaves. The slice, after being absorbed by the leaves, can promote the growth and development of cells, making the chlorophyll of cabbage leaves.

The increase in leaves, thickening of leaves, and abundant leaf juice improve the quality of cabbage leaves, making cabbage more soft, fresh, nutritious, bright and green in leaf color, and high in commerciality. ～～

Third, spraying vinegar on cabbage can prevent cabbage pests and diseases. Cabbage is grown in the open air, which is generally planted most in autumn, and there are fewer pests and diseases. The main insect pests are cabbage worms.

and aphids, diseases such as gray mold, cabbage heartburn.

disease, after the use of vinegar sprayed on Chinese cabbage, acetic acid.

It can inhibit the occurrence of Chinese cabbage aphids, promote the absorption of calcium in Chinese cabbage, and have a good inhibitory effect on heartburn and gray mold in Chinese cabbage. However, it does not have a great control effect on other diseases and insect pests.

The concentration of the vinegar that you obviously spray is too large, since it is too much, then you need to spray water in time to clean the vinegar on the leaves, and it will recover in a few days.

Cabbage needs sufficient nutrients during the growth process, in addition to nitrogen, phosphorus and potassium as top dressing, other medium and trace elements will also be used as foliar top dressing. Vinegar does not belong to the category of medium and trace elements, nor can it replace the use of medium and trace elements. There are several main reasons why vinegar can be used on cabbage to increase yields.

First, vinegar contains a small amount of amino acids, which promotes leaf growth, enhances photosynthesis, and the plant grows robustly, and the ability to resist diseases and insects is improved. However, vinegar contains relatively few ingredients, and cabbage needs to be sprayed many times during the growth process, and it needs to be sprayed 3 or 4 times during the whole growth process.

Second, some farmers use foliar vinegar spray to control diseases on cabbage. In autumn, the occurrence of cabbage soft rot is more serious, and there are situations such as shedding and rotten leaves, and it will also infect good plants. Cabbage soft rot is a bacterial disease that often occurs under alkaline conditions.

Foliar spraying of vinegar solution on cabbage is beneficial to inhibit the spread of pathogens, improve the disease resistance of plants, and reduce the occurrence of bacterial diseases.

In addition, vinegar can only be used as a precaution to prevent diseases. Some farmers grow cabbage in a relatively small area and do not want to use pesticides, so they can use this method to prevent bacterial diseases. In disease prevention, it is recommended to mix foliar fertilizers such as vinegar and potassium dihydrogen phosphate.

Vinegar should not be mixed with alkaline solutions such as plant ash to avoid reducing the effect. Cabbage spraying vinegar generally starts at the rosette stage, with a large leaf area and high absorption rate, and poor absorption at the seedling stage. Spraying at this time will enhance the growth of the plant.

Spraying at the beginning of the core can promote the core of cabbage and increase the weight of leaf balls. When spraying, it should be used on the spot, diluted 200 300 times on the cabbage, and the front and back of the leaves should be sprayed. It is best to spray in the morning or afternoon, and the effect is better.

On cabbage, you can spray edible vinegar from the seedling stage to the middle and late growth stage, generally after the cabbage seedlings are slowed, you can spray the first time, cabbage to the rosette stage, there are about 8 true leaves sprayed for the second time, and then sprayed again every 7 10 days, and then sprayed every 10 days, it is best to spray 3 4 times. According to the temperature of the concentration, the concentration of spraying edible vinegar is slightly different, in the summer and autumn when the temperature is higher, the concentration of edible vinegar spraying should be 300 500 times the liquid, in the season when the temperature is lower, the concentration of general spraying is 300 times the liquid. The higher the temperature, the thinner the concentration of the sprayed vinegar.

Odd! Why do farmers spray vinegar on cabbage, and what is the use of it?

First of all, let's understand the composition of edible vinegar, the most important ingredient in edible vinegar is amino acids, and secondly, it also contains nucleotides, lactic acid, sugars and other components. After diluting the vinegar with water and spraying it on the leaf surface of Chinese cabbage, it is similar to spraying foliar fertilizer, which can directly absorb the leaves of Chinese cabbage, which can play a role in regulating the growth of Chinese cabbage, so as to enhance the resistance of Chinese cabbage and make Chinese cabbage grow more robustly.

Therefore, cabbage vinegar spraying has the effect of promoting the increase of cabbage production and income, and at the same time, the amino acids and other components in white vinegar are absorbed by cabbage, and the taste of cabbage grown will be more delicious.

Secondly, due to the acidic substances in edible vinegar, it can have a certain inhibitory effect on white rot, gray mold and other bacteria of cabbage, and can reduce the occurrence of diseases. The acidity of edible vinegar is not suitable for the living environment of pests such as aphids and cabbage insects, and it can play a certain role in the prevention and control of some pests. Therefore, edible vinegar is used as a preparation for cabbage pest control, which is also natural and pollution-free, and there is no need to worry about any residue of harmful substances.

Before spraying Chinese cabbage with edible vinegar, it is necessary to dilute the vinegar with water, otherwise, because the concentration of vinegar is too high, it will not only not have a role in the cabbage after spraying, but will corrode the leaves of the cabbage and cause damage, so the method of spraying vinegar should be mastered.

The type of edible vinegar sprayed, whether it is white vinegar, rice vinegar, etc., which variety can be used, but white vinegar is worried, no matter which variety of edible vinegar we choose, before spraying, it must be diluted with about 400 times of water, and it is now sprayed and diluted, and try not to dilute and store it to prevent it from losing its effect after volatilization.

For the vinegar spraying operation of Chinese cabbage, you can choose different growth stages of Chinese cabbage, carry out it in the evening when the weather is fine, and use a sprayer to evenly spray the leaf surface of Chinese cabbage. It can be sprayed again at an interval of about 10 days, and under normal circumstances, vinegar can be sprayed three times during the entire growing season of cabbage, which can play a good role in the growth of Chinese cabbage and the control of pests and diseases.

In fact, edible vinegar can not only be used for the spraying of cabbage, but also for a variety of other vegetable varieties, it also has the value of use. May my experience be of great help to you.

It's okay to kiss, you can follow the following method.

4. Wrap the whole cabbage in plastic wrap. Finally, the wrapped cabbage is stored in a ventilated and cool place, and the high liquor can play a role in disinfection and sterilization, and can also lock the moisture in the cabbage. Wrapping it in plastic wrap can prevent the moisture inside the cabbage from losing to the outside.

In this way, the shelf life of cabbage can be effectively extended.

Kiss this is the answer to your query, I hope it can help you.

We will sincerely answer every question for you!

Your praise is the driving force for us to move forward, learn from each other and make progress together!

Last year, I didn't spray white vinegar on the cabbage I planted. So I'm not sure exactly what the effect is. I feel like I can kill the little flying insects.

9 degrees white vinegar spray can be sprayed vegetables.

9 degrees white vinegar has a strong bactericidal ability, because white vinegar contains a variety of nutrients, and after spraying on vegetables, it can be directly absorbed and utilized by plants and leaves. In this way, it can speed up the synthesis of chlorophyll, improve photosynthetic efficiency and nutrient accumulation, and increase yield and quality of various vegetables, as well as repel insects and prevent diseases.

Foliar spraying of white vinegar can not only improve the yield and quality of cabbage, promote growth, but also improve the ability of cabbage to withstand cold and improve the ability to resist diseases and pests in low temperature environment.

How to use white vinegar.

Under normal circumstances, the concentration of white vinegar solution is between, which will not cause harm to the cabbage leaves, but also is suitable for the nutritional needs of the cabbage leaves, so as to meet the needs of the white vinegar sprayed on the leaves each time and absorb all the white vinegar components and not waste. Therefore, when the commercial white vinegar stock solution is diluted to 10 or 20 times, the concentration of the white vinegar solution is diluted to the concentration.

In layman's terms, a bottle of white vinegar is 500 ml, about 500 grams, that is, one pound of weight, using 10 20 pounds of water, miscible with a pound of white vinegar, and the concentration drops after stirring evenly.

If the cabbage is in the rainy season or the soil moisture is good, the concentration can be prepared within 1%, and if the concentration is higher, the foliar surface of the cabbage will be damaged. That is to say, one pound of white vinegar is mixed with 10 20 pounds of water, depending on the concentration of the white vinegar stock solution.

If the soil moisture is poor, when the drought occurs, the concentration of white vinegar sprayed on the foliar surface of cabbage is much lower. To prepare such a concentration, each bottle of white vinegar needs to be mixed with 50 100 catties of water.

Under normal circumstances, cabbage or Chinese cabbage, in the whole growth and development period, can be sprayed three times to achieve the purpose of use. In the cabbage seedling stage, that is, around the 6-leaf stage, spray once, and re-spray in case of rain within 6 hours. At this time, spraying white vinegar can promote the rapid growth of Chinese cabbage, promote photosynthesis, increase the number of leaves in the leaf area, and make nutrient reserves for the ball.

In the rosette stage of cabbage, it can be sprayed once on the foliar surface, which can promote growth, promote rooting, improve drought resistance and cold resistance, improve immunity, reduce the harm of pests and diseases, and promote the formation of cabbage balls.

1.Dilution and frequency When spraying vinegar on Chinese cabbage, it must be diluted and then sprayed, so as not to directly spray vinegar to burn the leaves, although aged vinegar, vinegar and rice vinegar all contain amino acids, lactic acid and other components, but the concentration of aged vinegar is relatively high, it is best to use white vinegar or rice vinegar, first of all, the number of times to spray vinegar, although to Chinese cabbage.

2.In addition to paying attention to the number of times, there is also a need to pay attention to the spraying time Although the weather has cooled down when planting cabbage, the weather is still very hot at noon, and if it is sprayed at noon, it is easy to make the vinegar dilution evaporate quickly, and it will not play a role in increasing yield, so it is best to spray at 5 o'clock in the afternoon when the sun is about to set

When spraying vinegar on Chinese cabbage, it must be diluted before spraying, so as not to burn the leaves directly by spraying vinegar, although aged vinegar, vinegar and rice vinegar all contain amino acids, lactic acid and other ingredients.

Spraying vegetables with white vinegar and salt may cause vegetables to wilt for the following reasons:

1.The pH value is too low: White vinegar is an acidic substance, and salt is also an ionizing substance, which will increase the Xiangxiao conductivity of the water, making the pH value in the water decrease. If the pH is too low, it can disrupt the structure and metabolic processes of the plant cells, which can lead to wilting of vegetables.

2.Too much salt: Too much salt can cause the water inside the plant cells to penetrate outward, causing the cells to dehydrate and shrink. If the salt concentration exceeds the range that the plant can tolerate, it will accelerate the wilting of vegetables.

Therefore, it is recommended not to use white vinegar and salt to spray vegetables to avoid damage to plants. If you need to remove impurities and bacteria from the surface of vegetables, you can use clean water or a special vegetable detergent to clean it.

Spraying white vinegar with salt on vegetables will not cause vegetables to wilt, but long-term use may have an impact on plant growth. The mixture of white vinegar and salt has the effect of sterilizing early dates and weeding, so it can be used to control some pathogenic bacteria and weeds.

However, this mixture also contains ingredients such as acetic acid and sodium chloride, which, if used in excess or frequently, can cause damage to the plant's roots and foliage and even lead to wilting or death. Therefore, it is recommended to pay attention to the dosage and frequency when using it to avoid damage to the plant. At the same time, it is best to spray during the non-growing period to reduce the impact on the growth of plant damage.

Spraying vegetables with white vinegar and salt may cause the vegetables to wilt. The acidic components in vinegar may damage the cell walls on the surface of vegetables, leading to water loss and wilting. Salt also absorbs water from vegetables, exacerbating the degree of blighting.

Therefore, it is recommended not to use white vinegar and salt to spray vegetables. If you want to clean your vegetables, you can use clean water or a special vegetable detergent.
