The latest cause of hollowness of chili and its countermeasures

Pepper is a commonly used seasoning vegetable in our life. When it just comes out, the outer skin will only wrap the grain and get thicker as it grows, but for some reason, the quality inside does not continue to grow, so the middle part of the pepper is completely hollow. So what is the cause of pepper hollowness? Come and have a look with the editor.

I. the cause of occurrence

1. Poor flower bud differentiation.

In the greenhouse cultivation in autumn and winter, many farmers are worried that the plants will grow vigorously and drop flowers and fruits, so they do not keep warm in the shed in time, resulting in low night temperature, which directly affects the nutrients of A Hu and forms the problem of hollow fruit. Too low night temperature will lead to pepper can not be fertilized normally, in the later stage, it is very easy to appear flower and fruit drop and abnormal fruit, but also lead to physiological disorders of the plant itself, which is very easy to cause physiological diseases.

2. Excessive water control in the early stage.

After heading and flowering after planting, some farmers worry about excessive water control due to plant growth, resulting in relatively dry soil and slow plant growth. , insufficient water supply, resulting in poor flower bud differentiation and poor pollination, resulting in pistachios.

3. Root dysplasia.

Unreasonable greenhouse management will lead to poor root growth and development, hinder root absorption of trace elements, and lead to the occurrence of hollow fruit. This is mainly due to farmers' improper use of hormones and unreasonable cultivation, soil salinization hardening, resulting in poor root development and poor ability to absorb fertilizer and water in the later stage.

4. Unreasonable temperature control.

The suitable temperature for pepper to blossom and bear fruit is 28-30 degrees during the day and 15-18 degrees at night. The temperature difference between day and night should not exceed 10 degrees. If the temperature difference between day and night is too high, it will cause the plant to grow too much. Pepper generally begins to expand at night, and 15-18 degrees is the most suitable for nutrient transport and transfer to promote fruit growth, so too low or too high night temperature is disadvantageous to vegetable growth.

5. Reproductive growth and vegetative growth are out of balance.

There are many reasons for the nutrition imbalance, one of which is that the plant consumes more nutrients and the supply of flowers is insufficient, and the plant growth is weak, the stem is thin and not strong enough, the stem is loose and the nutrition is limited, coupled with the unreasonable picking of the lower fruit leads to excessive plant fall, resulting in insufficient nutrition supply.

6. Nitrogen deficiency

Blind fertilization caused antagonism between elements, resulting in inhibition of nitrogen absorption by plants, and the use of a large amount of immature farm manure, which required a large amount of nitrogen in the process of ripening, and then competed with plants for too much nitrogen, resulting in a lack of nitrogen.

II. Countermeasures

It is necessary to prune and branch in time, reasonably remove the hollow nuts on the side branches, and keep the trees from falling. At the same time, it is appropriate to control the night temperature at 15-18 degrees. During watering, trace element water-soluble fertilizer was applied together with potassium dihydrogen phosphate foliar fertilizer, which could effectively promote the expansion and elongation of hollow fruit, promote flower bud differentiation and pollination in the upper part of plant, and improve fruit quality.

The above is the introduction of pepper hollow reasons and countermeasures, hope to help you, want to know more related knowledge, please pay attention to us.
