The cause of the "three falling" problem of pepper and its prevention and treatment technology

What is the cause of the three-shot phenomenon of pepper? How to prevent the phenomenon of pepper falling? It is not difficult to say that the management of peppers is difficult. It is not easy to say that it is not the case. The following is a small series of Hui Nongwang to take everyone to learn the causes of the problem of peppers falling three times and how to prevent and cure them.

Recently, Li Geâ€™s peppers have made me most worried. The problem of fallen leaves and fruit drop is already the â€œhomely thingâ€ of his peppers in the field! The technology has also been said, the medicine has also been hit, but the effect is not seen, resulting in unsatisfactory harvest. In contrast, Lao Huang, who is next door to Li Ge, manages his family's pepper very well. Every time he picks the pepper, his face will always have a bright smile! The problem of pepper "three falling", he did not have one, and finally planted a good pepper, catch up with the good market, and sold a good price.
Itâ€™s a village, why do the two peppers managed by them have such a big difference? In the end, if you want to grow a good pepper, the "three falling" problem of falling flowers, fallen leaves, and falling fruits can't be ignored! It is from the very beginning that Lao Huang realized this problem, not just to find a solution to solve the problem, but also to pay attention to the cause of the problem!

Combine the methods mentioned in the conversation with Lao Huang, plus some of your own experience judgments, summarized as follows:

1. Soil fertility is not good.

Phosphorus deficiency and potassium deficiency in the soil, coupled with the poor quality of the pepper seedlings, can not be quickly and quickly released after planting. In addition, the management is not in place, the fertilization is insufficient, the soil nutrients can not keep up with the need of pepper growth, and the lower leaves will age and fall off.

Solution:

It is necessary to be cautious in selecting seedlings. It is necessary not only to do a regular job of applying base fertilizer, but also to apply organic fertilizer, phosphate fertilizer, potassium fertilizer, and appropriate amount of nitrogen fertilizer, because pepper is a crop that requires more potassium and phosphorus;

Also pay attention to the flowering period is the time when the pepper needs the most fertilizer, generally 10-15 kg of urea per acre, if you do not have enough phosphorus and potassium fertilizer in the early stage, you can use part of the phosphorus and potassium fertilizer at this time;

In the prevention and control of pests and diseases, 0.15% borax can also be added to reduce the incidence of "three falling" problems.

Note that before the fruit is placed, it is generally not watered and topdressed, and the vegetative growth should be controlled to promote vegetative growth.

2, caused by insufficient light

When the pepper grows, it will cause long-term rainy weather, resulting in insufficient light, or the planting density of the pepper plant is too large. When the growth is too strong, the middle and lower leaves will overlap each other, affecting the photosynthesis of the plant, and the leaves will be yellow. Fall off!

Solution:

It is best to use sorghum cultivation to improve the permeability of the soil;

Reasonable close planting should be carried out. After the ridge is closed, the lower old leaves should be removed in time to increase the ventilation and light transmission in the field.

3, caused by watering problems

If the soil is too dry, it will affect the problems of the various functions of the plant, causing the "three falling" problem; and if the rainfall is too large, or the water in the field will lead to the lack of oxygen in the roots, affecting the absorption of nutrients and water, also It is easy to cause the "three falling" problem.

Solution:

In high temperature and dry weather, especially in the flower bud stage and in the fruiting stage, pepper is sensitive to the need of water, and it should not be short of water. It should be watered in time;

Watering time should avoid the warmer time in the morning and afternoon, and should be around early morning or evening;

When watering, avoid flooding with large water. It should be lightly poured with small water to prevent damage caused by rain;

When encountering heavy rainfall or long-term accumulation of water in the field, it is necessary to remove accumulated water in time.

4, caused by fat

In the seedling stage and growing season, some people may inadvertently apply the organic fertilizer that is not fully decomposed, especially those chicken feces that have not been fermented, which will cause the burning of roots or roots, which will further cause the water and nutrients to be abnormal. Supply, causing the "three falling" problem.

Solution:

When you are under the bottom or topdressing, you must pay attention to whether the organic fertilizer is fully cooked;

If there is wilting of the upper plant, it is best to pull out the roots to see if there is rooting, and eliminate the cause of the disease. If it is still a small seedling, it is necessary to cultivate new roots in time to promote the re-growth of the plants. If it is in the growing season, it should be rapid. Take appropriate irrigation and drainage treatment.

5, serious pests and diseases

The "three falling" problem also occurs with the disease of pepper, such as anthracnose, blight, brown spot, leaf blight, powdery mildew, scab, white star disease, viral disease, etc., when it is harmed by tobacco budworms and sassafras, will cause.

Solution:

The solution of pests and diseases is more important than treatment, prevention in advance, and prevention and control in time. Generally use 0.3% copper sulfate solution before and after the bud, spray 2-3 times, can play a protective role!

(1) Anthrax

Control agent: protective fungicide: chlorothalonil, azoxystrobin, pyraclostrobin. Therapeutic fungicides: difenoconazole, prochloraz, etc.
