What should I do if I plant seedlings in the ground? 20. What should I do if I plant and burn seedli

Watering is right to alleviate the burning of seedlings, but it is better to pay attention to the watering time in the morning, and the amount of watering should not be too large, so as to avoid further damage to the roots and aggravate the symptoms of wilting. It is also necessary to pay attention to the watering interval should not be too long, 2-4 days is appropriate, in order to continuously dilute and wash away the harmful substances around the root system to avoid aggravating the root injury. As long as the root burning is not very serious, it can be restored after a period of time.

Under normal circumstances, the concentration of cell fluid in plant root hairs is always greater than the concentration of soil solution, so the water in the soil solution penetrates into the vacuole through the cell wall, cell membrane and cytoplasm of the root hairs, and then gradually penetrates into the layers of cells in the epidermis, and finally enters the ducts, which are transported to other organs such as stems and leaves.

The normal growth of plants needs to continuously absorb water from the soil, and the direction of water flow is determined by the water potential of the system, water always flows from the high water potential to the low water potential, high and low are relative, the water potential in a system changes with the change of conditions.

If the fertilization concentration is too high (that is, too much fertilization), the water potential in the soil is lower than the water potential in the root, and the water in the soil not only can not enter the root system, but the water in the root will flow out backwards, and the ion concentration in the soil is relatively large, exceeding the concentration of the crop cell sap, so that the crop cell loses water and separates the plasma wall, resulting in serious water loss of the whole plant, as if it has been burned, so it is called "burning seedlings".

Stir some grass ash or carbon ash in the soil, dilute the fertilizer effect in the ground, burn seedlings are mainly related to the fertilizer effect in the ground, apply too much fertilizer in the ground or farmhouse fertilizer, sprinkle a layer of grass ash or deciduous grass and wood fertilizer on the outer layer of the soil, and then use a rotary tiller to turn the soil once, so as to dilute the fertilizer effect, and then sow seeds.

Garlic seedlings are generally divided into chemical fertilizer seedlings, which are mainly caused by excessive application of nitrogen fertilizer. Organic fertilizer fire seedlings are also known as immature organic fertilizer fire seedlings. For example, immature chicken manure, pig manure, and other fertilizers are injected into the soil.

After this fertilizer is applied to the soil, it continues to ferment in the soil to produce a large amount of heat and organic acids, which destroy the root system of the plant, causing bacterial infection, which in turn causes the root system to rot. The leaves of the seedlings turn yellow, their growth is stunted, and they gradually die. Excessive nitrogen content in chemical fertilizers can cause ammonia poisoning, root rot, short yellow leaves, and gradual wilting.

Garlic seedlings are burned mainly for prevention. Once the seedlings are burned, the yield and quality will inevitably be affected.

What is planted in the ground? Is it a fruit and vegetable plant, or a flower plant? Generally, the seedling burning may be a problem of soil pH or excessive fertilization, you first see what kind of reason, if it is excessive fertilization, it is easy to do, if it is a soil pH problem, then buy the corresponding fertilizer to adjust the pH.

1. Generally, after the seedlings are burned, the method of frequent irrigation and drainage can be taken immediately to change the water, so as to reduce the concentration of fertilizer in the soil, so that the fertilizer in the soil can be fully dissolved in the water, and then drained.

2. After detoxification, the seedlings can be transplanted into new pots to give the plants a good soil environment. Guess Dan.

3. If the plant is seriously ablated and cannot be saved, then it can only be abandoned.

Remedy with these five steps:

Tools required: One electric sprinkler.

1. Use an electric sprinkler to rinse the roots of the plants in the pot, the purpose of this step is to quickly reduce the fertilizer concentration.

2. As can be seen from the red circle in the picture, the water has leaked out of the small hole at the bottom of the pot, and even then it is necessary to continue to rinse thoroughly to flush out the fertilizer with too high concentration.

3. Spray the leaves with an electric sprinkler to play the role of leaf wetting.

4. Place it in a ventilated but dark place, the purpose of this step is to avoid photosynthesis, thereby intensifying the absorption of fertilizer.

5. Wait until the soil in the pot is dry.

Precautions: It is best to put it in the hand sink when rinsing to prevent water from flowing everywhere.

After the flowers are burned, the method of frequent irrigation and drainage can be taken immediately to change the water, reduce the concentration of fertilizer in the soil, and immediately water enough water to make the fertilizer in the soil fully dissolved in the water, and then drain the water;

After detoxification, the flowers can be transplanted into new pots, giving the plants a good soil environment, and applying fertilizer can rejuvenate the plants when applied properly;

If the plant is so poisoned that it can't be saved, then we have to give up, but for potting soil, we can still treat it and reuse it. Remember to plough and rinse the soil, otherwise the replanted plants will not escape the law.

In the process of planting plants, in order to make the plants grow quickly and well, we usually use the method of fertilization. However, once too much fertilizer is applied, it will cause the effect of pulling out seedlings to promote growth, and will cause the plant to "burn seedlings".

If the fertilization concentration is too high or too much fertilizer, the water potential in the soil will be lower than the water potential in the root, the water in the soil not only can not enter the root system, but the water in the root will flow out, the ion concentration in the soil is relatively large, exceeding the concentration of crop cell sap, so that the crop cell loses water, resulting in serious water loss of the whole plant, just like being burned, so it is called "burning seedlings".

Burning seedlings will cause the plant to appear to stop or slow down significantly, the leaves of the plant will be yellow, the texture will become soft, the edges will be curled, the tips of the leaves will gradually turn yellow, and the stems will also appear to be shortened internodes and the color will turn yellow.

Too much fertilizer will produce fertilizer damage, if the phenomenon of burning seedlings has appeared.

When the situation is more serious, it will cause seedlings to burn, and watering after fertilization can reduce the concentration of soil solution, so that the concentration of soil solution is less than the concentration of crop cells, so that crop cells can absorb water normally Therefore, the best way to solve the problem is to water a lot.

In recent years, due to the improper application of compound fertilizer, the phenomenon of crop seedling burning has occurred from time to time. It is necessary to pay attention to the cautious use of urine-based compound fertilizer and high-tower compound fertilizer with high nitrogen content, especially the inferior compound fertilizer with serious excess of biuret. Because biuret is harmful to the germination and growth of seeds, do not use the fertilization method of "seed fertilizer in the same bed" or "fertilizer in the deep position under the seed" when making seed fertilizer.

Otherwise, it is easy to burn seedlings. In the event of fertilizer damage, the following measures can be taken to remedy it.

1.Replanting and replanting. For rice seedlings that cannot be saved due to serious poisoning, they should be immediately ploughed and raked, thoroughly washed and replanted.

For cotton seedlings and watermelon seedlings with serious poisoning, other crops can be planted in time, such as summer corn and summer soybeans, and attention should be paid to avoid the original fertilization position to prevent re-poisoning. For individual diseased plants with serious poisoning, they should be replanted from their original positions.

2.Rinse with water. After the poisoning of aquatic crops such as rice, it is necessary to immediately take the method of frequent irrigation and drainage to change the water, eliminate the shrinkage of the second vein, and reduce the concentration.

It is best to do a little before draining, and drain the water after the lake is cleared, so that the effect is better. Cotton and other dry crops that are more severely poisoned should also be immediately watered with enough water, so that the constriction of the second vein is lost downward, spread to the surroundings, and reduce the concentration.

3. Supplemental fertilizer. After rice detoxification, about 25 kg of nitrogen, phosphorus and potassium compound fertilizer can be applied per mu to promote the growth of seedlings; For cotton seedlings (watermelon seedlings), about 30 kg of compound fertilizer can be applied in the ditch, and foliar fertilizers such as potassium dihydrogen phosphate with low concentrations can also be sprayed.

Remedies for burning seedlings:

1. Rinse with water

Generally, after the seedlings are burned, people can immediately take the method of frequent irrigation and drainage to change the water, so as to reduce the concentration of fertilizer in the soil, and immediately water enough water to make the fertilizer in the soil fully dissolved in the water, and then drain the water.

2. Supplemental fertilizer

After detoxification, the seedlings can be transplanted into new pots to give the plants a good soil environment, and fertilizer can be applied to rejuvenate the plants when used properly.

3. Replanting and replanting

If the plant is too badly ablated to be saved, then it has to be abandoned, but for potting soil, people can still treat it and reuse it. But the soil must be ploughed and rinsed. Therefore, during the planting of seedlings, people must remember to avoid blind fertilization, and they must be watered in time after fertilization, so as to minimize the phenomenon of burning seedlings.

Causes of the phenomenon of seedling burning:

Generally, the concentration of the soil solution is greater than the concentration of the root hair cell fluid of the plant after too much or too concentrated fertilizer is applied to Chang, resulting in the water in the root hair cell fluid of the plant penetrating into the soil solution, and finally the root hair cells of the plant are separated from the plasma wall due to water loss.

As a result, the phenomenon of wilting occurs. After burning seedlings, the growth rate of the plant will be slowed down, the leaves and stems will turn yellow, the leaf edges will curl, and the tips of the leaves will gradually turn yellow, which may lead to the death of the plant if the seedling burning phenomenon is severe.

Watering more water can dilute the fertilizer.
