Is burning seedlings wilting? What is the phenomenon of burning seedlings?

No. It's not the same.

It is well known that the root system of plants absorbs water and loses water through transpiration.

The absorption of water maintains a dynamic equilibrium with the loss of water.

And when certain conditions in the outside world change.

This balance is about to be upset.

For example, applying too much fertilizer at one time or too thick.

This results in a concentration of soil solution that is greater than that of root hair cell sap.

As a result, the root system no longer plays the role of water absorption, but loses water.

plus transpiration due to water loss.

Resulting in severe water loss of the whole plant.

It's like being burned.

That's why it's called burning seedlings.

Wilting is also a disruption of the balance between water absorption and water loss.

More water will be lost than absorbed.

Leads to water deficit in plants.

Cell rigidity cannot be maintained.

Causing young parts such as stems and leaves to droop, shrink or curl.

In terms of personal knowledge and understanding of this piece.

Plants in a state of burning seedlings not only do not absorb water.

On the contrary, it is constantly losing water.

Wilting, on the other hand, occurs when the water potential of the soil falls below a certain value.

caused by an imbalance between water absorption and water loss.

Therefore. Burning seedlings and wilting are also a state of water shortage.

The reasons for this state are different.

Wilting is the manifestation state of burning seedlings, and the most direct manifestation after burning seedlings due to excessive fertilizer amount is plant water loss and wilting. However, there are many causes of wilting, such as drought and lack of water, not necessarily due to excessive fertilization, so it is not possible to simply equate seedling burning and wilting.

The cause of seedling burning, wilting is the result, and burning seedlings can lead to wilting.

Because if the fertilizer is too much or too concentrated at one time, the concentration of the soil solution will be greater than the concentration of the root hair cell sap, and as a result, the water in the root hair cell sap will penetrate into the soil solution, so that the root hair cells can not only not absorb the water, but also lose the water, so that the plant wilts, which leads to the phenomenon of burning seedlings.

Chemical fertilizers are composed of a variety of different salts, so long-term and large application of these fertilizers composed of salts, when the fertilizer enters the soil, it will increase the concentration of the soil solution and produce osmotic pressure of different sizes, crop root cells not only can not absorb water from the soil solution, but pour the water in the cytoplasm into the soil solution, which leads to crop damage.

The reason for this is that too much fertilizer is added, so the seeds are burned and the seedlings are not grown.

Crops have burned seedlings, dead trees because the fertilizer is sprinkled too much, if there is a surplus, the plant can not absorb the seedlings will burn and die, then this time must be watered, the next time you use fertilizer, you can not be too close to the roots of no crops.

The reason for burning seedlings is generally that the concentration of the soil solution is greater than the concentration of the root hair cell fluid of the plant after too much fertilization or too concentration, 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, resulting in wilting. 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.

Methods for plants to avoid burning seedlings and treatment after burning:

Excessive fertilization is the main reason for plant burning, so it can be done in a small amount and many times when fertilizing. The concentration of fertilization is also one of the important reasons for plant burning, so it must be proportioned in an appropriate way before fertilization. Plants need to stop fertilizing immediately after the phenomenon of seedling burning, so as not to make the seedling burning situation more serious.

After the plants are burned, you can try to dilute the fertilizer in the soil with more watering, and then drain the excess water; You can also try to change the plant to a new soil environment and then re-maintain it.

The reason for the phenomenon of burning seedlings: excessive fertilizer application to make potatoes and bright wax into key Kai burning roots and seedlings. Top dressing is close to the root system of garlic, which directly produces the phenomenon of seedling burning.

1. Excessive application of nitrogen fertilizer causes root burning and seedling burning. Solution: Water immediately to dilute the nitrogen fertilizer concentration, reduce the soil temperature, and alleviate the damage of nitrogen fertilizer to the plant. After 2-3 days, the seedlings can slowly resume growth.

2. Top dressing is close to the root system of garlic, which directly produces the phenomenon of burning seedlings. Solution: In order to promote the difficulty of water and fertilizer absorption caused by root burning, you can water naphthalene acetic acid, indoleacetic acid, sodium naphthalene acetate, indole butyric acid, naphthalene oxyacetic acid and other rooting agents.

The dilution factor is generally 100 times, and watering near the root system can promote the rapid generation of new root systems.

3. The phenomenon of burning roots and seedlings produced by unrotted farmhouse fertilizer. Solution: After burning the roots, according to the situation, during the recovery of root growth, foliar spraying of urine slipperin, white vinegar, amino acid fertilizer and micro fertilizer, etc., can be quickly absorbed by the leaves, enhance the ability to resist stress, and shorten the seedling delay time.

4. The concentration of foliar fertilizer spraying is too high or the use method is improper. Solution: Immediately spray a large amount of water to reduce the concentration of nitrogen fertilizer. Then the foliar surface is sprinkled with plant ash, and the alkaline substance and ammonium ions are used to react to eliminate the damage to the leaves.

5. The concentration of ammonia in the shed is high, resulting in the phenomenon of burning leaves and seedlings. Solution: If conditions permit, ammonia can be removed by means of ventilation, or clean water can be sprayed to increase the humidity in the shed, so as to promote ammonia into ammonia and be used by the roots.

1. The reason for the phenomenon of burning seedlings is that too much or too concentrated fertilizer is applied at one time, which will cause the concentration of soil solution to be greater than the concentration of root hair cell sap, and as a result, the water in the root hair cell sap will penetrate into the soil solution, so that the root hair cells can not only not absorb water, but also lose water, so that the plant wilts.

2. Under normal circumstances, the concentration of the cell fluid of the root hairs of plants is always greater than the concentration of the soil solution, so the water in the soil solution penetrates into the vacuole through the cell stimulus of the root hairs, the cell membrane, and the cytoplasm, and then gradually penetrates into the layer of lead imitation layer cells within the epidermis, and finally enters the duct, which is transported to other organs such as stems and leaves by the duct.

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 fertilizer), the water potential in the soil is lower than the water potential in the roots, the water in the soil not only can not enter the root system, but the water in the roots will flow out, the ion concentration in the soil is relatively large, the ultra-slippery type exceeds the concentration of crop cell sap, and the slag is lifted so that the crop cells lose water and the plasma wall is separated, resulting in serious water loss of the whole plant, just like being burned by Rubi, so it is called "burning seedlings".
