Watering first or fertilizing first, fertilizing first or watering first Do you water before fertili

If it is a chemical fertilizer, water first and then fertilize. Buried chemical fertilizers are easy to melt in moist soil, but the root system may not be removed quickly compared to post-watering. However, after watering, there is a possibility that the seedlings may burn. Affects crop growth.

The more the farmyard fertilizer is exposed to the air, the more water it comes into contact with, the organic matter is decomposed by microorganisms and is accelerated for the crops to absorb, and the fertilizer is lost less. Therefore, farmhouse fertilizer should be topdressing first and then watering.

Generally speaking, fertilization is applied first and then watered, which is conducive to the fertilizer dissolving in water, being evenly absorbed by the soil, and then absorbed by plants.

Fertilize first, then water! In this way, the fertilizer can be diluted, and there is no fear that it will hurt the crop. The second is to allow the fertilizer to be fully absorbed by the crops.

Hello; The question you are asking is a scientific [plant] field question, to put it simply; Those who have agricultural knowledge know that no matter what you are planting [dry land or seedling land], you should basically apply fertilizer first [according to the situation or sprinkle or bury] and then water, which is convenient and labor-saving and will not lose the content of various elements of fertilizer.

In fact, these two processes have no influence on each other, and they can also be carried out separately or together, so there is not much difference between adding water first and fertilizing first.

If you want to raise flowers well, fertilization is the key, and most people will not dare to fertilize, which is the right way.

Flushing fertilization refers to dissolving fertilizer in water and then flushing with water, and there is no question of watering or flushing fertilizer first. Generally, there are 6 main types of fertilizer, including macroelements, macroelements plus trace elements, trace elements, amino acids, phytohumic acids and other categories, including chitin, seaweed, and other organic matter.

The relationship between fertilizer and water is that water can take away nutrients, and it can also be sent to the root zone, different fertilizers have different properties, such as urea, which is easily soluble in water, and it moves faster with water; Phosphate fertilizers move relatively slowly; Potash is just in the middle, and it is relatively soluble in water, but it moves a little slower than nitrogen and a little faster than phosphorus; Compound fertilizer is more complicated, there are both nitrogen, phosphorus and potassium in it, so it is difficult to grasp the law between water and fertilizer, so we should apply compound fertilizer deeply and then irrigate. Be careful not to irrigate too much, it will be wasted if you bring the fertilizer under the root system.

You can water immediately after fertilization, and the amount of watering can be determined according to the moisture of the soil. Do not water too much water after fertilization, if the pot is moist for a long time, it will cause the plant to be unable to breathe, resulting in root rot. The soil can be loosened before fertilization to promote the absorption of fertilizer by the plants.

Immediate watering with urea is not recommended, as immediate watering can lead to loss of fertility.

You can water immediately after fertilization, but you can't apply fertilizer after watering. Watering after fertilization can promote the absorption of nutrients in the fertilizer by the plants, ensure that the fertility in the fertilizer can be fully exerted, and also dilute the fertilizer in the soil, which can avoid excessive fertility and burn the roots of the plants, and can also prevent the soil from being too dry.

Don't water too much after fertilization, if you water too much, it will cause the pot to be wet for a long time, and the roots of the plant will not be harmed to absorb oxygen, resulting in root rot. When there is enough moisture in the pot, watering after fertilization is not recommended. It is also necessary to pay attention to fertilizer when applying fertilizer, if there is too much fertilizer, it is easy to cause the roots of the plant to be burned, resulting in rot.

Fertilization should be decided according to the growth of the plant, and the number of fertilization can be increased appropriately during the growth period of the plant. Before using the fertilizer, the plant can be Song Yu, wait for the pot to dry slightly before fertilizing, and then spray the foliage with water after fertilization, so as not to burn the leaves with residual fertilizer.

It is not advisable to water immediately after using urea fertilizer, which is an amide nitrogen fertilizer and is easily soluble in water. After dissolving in water, urea will be lost, resulting in a large loss of fertility and waste. Generally, after making liquid fertilizer, it will be better to water the next day, mainly to prevent the concentration of fertilizer from being too high.

If a strong fertilizer is used during fertilization, it can also be watered immediately to dilute the fertilizer.

1. From the perspective of fertilizer efficiency, it is natural to sprinkle fertilizer first and then water, because only in this way can fertilizer be fully dissolved into the soil, so that crops can be absorbed and utilized as much as possible.

2. However, even if it is watered first, there are still certain defects, such as the reduction of fertilizer efficiency utilization rate caused by fertilizer volatilization after managing. This is entirely possible, theoretically speaking, based on the solubility of chemical fertilizers, when the field is relatively wet, sprinkle fertilizer, and then water a stubble, which is completely different. A stubble of water.

It can ensure that the chemical fertilizer can be dissolved into the soil to avoid volatilization, and the subsequent stubble of water can ensure that the chemical fertilizer can be fully dissolved around the root system of the soil, which is convenient for absorption and utilization by the plants.

3. If the method of watering first and then spreading fertilizer is adopted, it may lead to the chemical fertilizer not being fully dissolved, and the fertilizer loss caused by this will be greater. This is also the reason why farmers consider applying fertilizer when it is about to rain or when it is raining, rather than when the rain stops.

Sprinkle compound fertilizer.

After that, it is recommended to water every other day, and if the soil is too dry, it is recommended to water first and then fertilize. To fertilize plants, it is necessary to pay attention to the choice of fertilizer, as plants have different needs for fertilizer at different stages. It is also necessary to control the fertilization concentration, avoid excessive and excessive fertilization, and stop fertilizing after the plant enters the dormant period.

In the process of cultivating plants, it is recommended to water every other day after applying compound fertilizer to avoid fertilization burns.

The roots of the plant. Also, if the soil is too dry, it is recommended to water first and then fertilize.

1. Fertilizer selection

When fertilizing plants, we should first pay attention to the choice of fertilizer, because plants have different needs for fertilizer at different growth stages, and reasonable preparation of fertilizer is the key. In particular, it is necessary to control the amount of nitrogen fertilizer, as too much nitrogen fertilizer can easily lead to plant growth.

2. Fertilization concentration

When fertilizing, we should also pay attention to the concentration of fertilizer and the amount of fertilizer, master the principle of applying more thin fertilizer, rather apply more thin fertilizer several times, and do not fertilize too much at one time, it is easy to burn the roots of the plant and affect the growth of the plant.

3. Fertilization is prohibited during the dormant period

After the plant enters the dormant period, the growth rate is slower, and the demand for nutrients is also reduced, and fertilization is easy to cause fertilizer damage at this time, so it is forbidden to fertilize the plant during the dormant period.

When fertilizing, the plants are watered so that the plants can better absorb the nutrients in the fertilizer. During the maintenance period, watering the plant during fertilization can also dilute the fertility and avoid excessive fertilizer concentration and damage to the plant's root system. During the maintenance period, it is necessary to fertilize the plants in an appropriate amount and control the concentration of fertilizer to avoid damaging the root system of the plants.

During the growth period of the plant, when fertilizing it, it needs to be watered appropriately, which is conducive to the plant's absorption of fertilizer. Fertilizers contain a large amount of nutrients that are ionic in the liquid and can be absorbed by the roots of plants. Plants can grow better after absorbing nutrients and provide nutrients for branches and leaves.

When fertilizing plants, the right amount of watering can dilute the fertility. During the maintenance period, the root system of some plants is shallow, and after fertilization, if not watered in time, it will hurt the root system of the plant, which is easy to make the plant grow poorly. Proper watering can help plants absorb nutrients and protect their roots.

When fertilizing plants, it is necessary to pay attention to the amount of fertilizer and fertilize the plants in an appropriate amount. During the maintenance period, fertilization should be carried out as much as possible in a cool climate, not in the middle of the day. If the fertilizer is too much or the concentration of fertilizer is too high, it is necessary to water the plant in moderation to dilute the fertility and then put the plant in a cool and ventilated place.

Most plants need to apply an appropriate amount of nitrogen fertilizer in the early stage of growth, which is conducive to the growth of the stems and leaves of the celery pure plant. Before the flowering and fruiting period, it is necessary to apply thin fertilizer frequently, and the fertilizer is mainly phosphorus and potassium fertilizer, which is conducive to the opening of flowers. During the winter period, the plant goes into a dormant state, and after it stops growing, it is necessary to stop fertilizing.

When fertilizing, watering is because: it is conducive to the absorption of fertilizer, and the nutrients can only be absorbed by plants in an ionic state, and the nutrients in the fertilizer can be in an ionic state in the liquid; Avoid burning seedlings, watering can dilute the problem of high concentration of soil solution caused by fertilization to avoid burning seedlings.

Do not over-fertilize and do not apply unrotted organic fertilizer, so as not to fertilize plants and reduce the harm of underground pests.

Watering when fertilizing is because:It is conducive to the absorption of fertilizer, and the nutrients can only be absorbed by plants in the state of detachment, and the nutrients in the fertilizer can be in an ionic state in the bold body of liquid celery; Avoid burning seedlings, watering can dilute the problem of high concentration of soil solution caused by fertilization to avoid burning seedlings.

Do not apply excessive fertilizer, do not apply unrotted organic fertilizer, so as not to fertilize plants and reduce the harm of underground pests.

The principle of water absorption and water loss in plant cells.

The principle of water absorption and water loss in plant cells is that water is lost when the concentration of the solution outside the cell is greater than the concentration inside the cell, and water is absorbed when the concentration of the solution outside the cell is less than the concentration inside the cell. Too much fertilization at one time will make the concentration of the soil solution too high, greater than the concentration of the plant cell solution, and the plant cells will lose water, causing the plant to wilt due to water loss.

When the situation is more serious, it will cause seedling burning. Watering after fertilization can reduce the concentration of soil solution, so that the concentration of soil solution is less than the concentration of the cells of the seed, so that the crop cells can absorb water normally. Therefore, the best solution is to water abundantly.

Be sure to water it first, because the roots of the transplanted tree will be damaged, and if you apply fertilizer, the tree will be burned to death.

There are many ways to plant trees, and it is necessary to adopt appropriate planting methods according to the habits, development status, and growth environment of the tree species. Bare root planting and planting with soil balls are common planting methods, and the following will talk about the characteristics of these two methods:

1. Bare root planting, this method is mostly used for evergreen tree seedlings and most deciduous tree species. The key to bare root planting is to protect the integrity of the root system, the backbone roots should not be too long, and the lateral roots and fibrous roots should be as many as possible. From digging to planting, it is important to keep the roots moist to prevent the roots from losing water and drying out.

Root beating is one of the commonly used protection methods, which can increase the survival rate of transplanting by 20%.

2. Transplantation with soil balls, evergreen tree species and some tree species that are difficult to survive with bare roots, such as chestnut, long hickory, horse chestnut, magnolia, etc., transplant with soil balls in multiple rows; Large tree planting and planting during the growing season also require soil balls to improve the survival rate.
