Pepper excessive fertilization causes fertilizer damage.

In the process of planting pepper, many growers spray some foliar fertilizer properly, which has a very good effect on improving the yield of pepper. However, if scientific fertilization is not carried out in this process, it will easily cause fertilizer damage to pepper, which is not only not conducive to the growth of pepper, but also

Pepper is widely used in diet. Many growers spray some foliar fertilizer properly during the process of planting pepper, which has a very good effect on improving the yield of pepper.

However, if there is no scientific fertilization in this process, it will easily lead to fertilizer damage of pepper, which is not only not conducive to the growth of pepper, but also may lead to its withering and death.

Causes of fertilizer damage of pepper

Excessive use of chemical fertilizers

The main reason of pepper fertilizer damage is that there is no scientific and reasonable amount of fertilizer used, and the amount of disposable fertilizer is too large, which exceeds the tolerance of pepper.

This will cause the root system of pepper to be damaged and the absorption function will be reduced. Once it is reduced, it will easily affect the growth of leaves and the absorption of nutrients, thus causing fertilizer damage.

The fertilizer damage of pepper is a huge waste for pepper itself, which will affect the normal growth of pepper and lead to the decline of yield and quality.

Therefore, it is very necessary to prevent and control diseases in time and in advance. Spraying too much pepper fertilizer will lead to local whitening or some gray spots on the leaves. The more serious the disease develops, the bigger the spots will be.

Farmhouse manure is not decomposed.

When farmyard manure is not completely decomposed, it will be planted in the field where peppers are planted, which will lead to serious seedling shortage and rotten roots.

No watering and fertilization in dry weather

When the weather is dry, it is easy to cause fertilizer damage to pepper by applying fertilizer without watering and diluting.

The fertilizer is too single.

In order to increase the growth of pepper seedlings, many farmers will use too much single fertilizer, especially nitrogen fertilizer. The most obvious symptom will lead to moss in the root area of pepper.

Control pepper fertilizer damage 1, spray clear water to dilute fertilizer.

If this symptom occurs, it is necessary to spray clear water immediately, and spray some water on the front and back of the leaves properly, which can dilute the fertilizer and help reduce the damage to the roots.

2. Root irrigation in time.

Do a good job of irrigation, the root system of vegetables is mostly active, and when fertilizer damage occurs, timely root irrigation can promote the root system to absorb enough water.

This can dilute the concentration of fertilizer in the soil, prevent the severity of the disease and alleviate the symptoms of fertilizer damage.

3. Spraying plant nutrient solution to enhance immunity

When the symptoms of fertilizer damage appear, plant nutrition immune solution can also be sprayed to enhance the resistance of pepper plants themselves.

Generally speaking, after watering for two or three times, the fertilizer damage can be alleviated, and spraying immune night at the same time can improve the resistance of pepper itself to fertilizer damage.

4, before fertilization, open hole irrigation.

When the weather is dry, before fertilization, dig a small hole about 10 cm away from the root of pepper. Then fill the hole with water, wait until the water penetrates into the soil, then apply chemical fertilizer, and then cover it with chemical fertilizer, so as to better prevent the occurrence of fertilizer damage.

5. Choose the time for fertilization.

If you want to use nitrogen fertilizer, you should pay attention to the characteristics of nitrogen fertilizer, because nitrogen fertilizer is volatile, and the fertilization time can be changed to about three o'clock in the afternoon, so as to prevent ammonia gas produced during the volatilization of nitrogen fertilizer from affecting pepper leaves.

Pepper will encounter many diseases in the process of planting, some of which are brought to pepper by improper artificial planting techniques, especially like fertilizer damage.

Therefore, before planting, we must first understand the scientific methods of planting, and don't worry about diseases during planting. Preventing and controlling diseases in time and strengthening field management can plant high-yield and high-quality peppers more scientifically.
