Anonymous users2024-02-09Pepper is smoked by fertilizer, too much fertilizer at one time, will make the concentration of soil solution too high, greater than the concentration of plant cell solution, plant cells lose water, cause plants to wilt due to water loss; When the situation is more serious, it will cause the seedlings to be burned 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 solution is to water abundantly.
1. Several common irrational application of chemical fertilizers.
Unreasonable fertilization is usually caused by the unreasonable amount of fertilization, fertilization period, and fertilization method. Common phenomena are:
1. Shallow fertilization or sprinkling. Fertilizer is volatile, lost or difficult to reach the roots of crops, which is not conducive to crop absorption, resulting in low fertilizer utilization rate. Fertilizer should be applied 16-650px below the seed or plant side.
2. Dichlorofertilizer. The compound fertilizer produced with ammonium chloride and potassium chloride is called dichlorofertilizer, which contains about 30% chlorine, is easy to burn seedlings, and should be watered in time.
3. Urea-based compound fertilizer. Reduced biuret has high nitrogen content and is easy to burn seedlings, so it is necessary to pay attention to the depth of watering and fertilization.
4. Improper application of chemical fertilizers to crops may cause fertilizer damage, seedling burning, plant wilting and other phenomena. If too much one-time application or insufficient soil moisture after fertilization, the concentration of soil solution will be too high, and it will be difficult for crop roots to absorb water, resulting in wilting and even death of plants.
5. Excessive use of a certain nutrient will not only poison crops, but also prevent crops from absorbing other nutrients and cause nutrient deficiency. For example, excessive nitrogen application can cause calcium deficiency; Too much potassium reduces the availability of calcium, magnesium, and boron; Too much phosphorus reduces the availability of calcium, zinc, and boron.
6. It is not suitable to directly apply fresh human feces and urine. Fresh human feces contain a large number of germs, toxins and parasite eggs, if applied directly without rotting, it will contaminate the crop and easily transmit diseases, and it needs to be fermented at high temperature or harmless before it can be applied.
2. Precautions for reasonable fertilization.
In order to prevent the occurrence of the above fertilizer damage, attention should be paid to reasonable fertilization.
1. Increase the application of organic fertilizer to improve the buffering capacity of the soil.
2. Soil testing and formula fertilization, according to the level of soil nutrients and the demand of crops for nutrients, reasonable fertilization, do not increase the amount of fertilizer at will.
3. Full-layer fertilization. The same amount of chemical fertilizer, when applied locally, often causes a sharp increase in the concentration of local soil solution, damaging the root system of crops, so that the fertilizer is evenly distributed in the entire tillage layer, so that the crops can avoid damage. **From China Bio-Organic Fertilizer Trading Network).

When people are nervous, fearful, and excited, nerve impulses will be transmitted from the cerebral cortex to the apocrine glands, resulting in rapid enhancement of their secretion and excretion, resulting in increased sweating or foot odor.
