Farmers who grow peppers know that peppers are prone to grow up, especially after peppers are planted. The stalks of the pepper are slender, the leaves are large and thick, the flower buds and the flowers are thin and weak, and the results are not; or the stems are thin, the stems are prominent, the leaves are thin and pale, the flower buds and the flowers are thin, and the fallen leaves are severe. The impact on farmers is very large, so what is the cause of the protection of the peppers? How to prevent and cure?

First, the reason for protecting the location of the pepper
Generally, the mid-late maturing varieties are easy to grow. The main reason for the long-term growth of capsicum in spring is that the soil is too wet, the relative humidity is over 80%, the nitrogen fertilizer is too much, or the continuous rainy weather, the relative humidity of the air is often higher than 80%, the light is insufficient, and the planting has been completed. Dense, or poor ventilation and ventilation, the peppers planted in the protected area, the first door can not sit, it is caused by high temperature and high humidity.

Second, the prevention and control measures for the protection of the capsicum
1. Prepare for early planting and cultivate strong seedlings
10 to 30 days before planting, preparation work for land preparation, application of base fertilizer, covering the roof membrane of the greenhouse and ditching and drainage around the skirt and the greenhouse, so that the humidity in the shed is lower and the temperature is higher when the seedlings are planted. Slow seedlings.
2, timely planting, timely prevention and control of pests and diseases
At present, most of the peppers are cultivated in small seedlings, and they are generally rooted, so they are slow in seedlings. When the pepper is 5~6 leaves and 1 heart, it has a certain difference from the previous large seedlings (7~8 true leaves). After planting the seedlings, the drug can be sprayed once every 10 days or so to prevent the disease from happening.
3, timely ventilation, timely pruning
After the plants are slowed down, keep a certain temperature, and be bold and ventilated to reduce the humidity inside the shed. When the minimum outside temperature at night is not lower than 15C, it should be ventilated day and night. When entering the high temperature stage in summer, the shading net can be appropriately used for shading and cooling. In the middle and late stages of plant growth, the appropriate amount of pruning and leafing should be timely and appropriate, so that the ventilation and light transmission is good, and the plants are prevented from being closed by the field.
4, control fertilizer
In the case of sufficient use of the base fertilizer, it is no longer fertilized and watered before flowering and fruit setting, especially covered with plastic film. After the door pepper is stabilized, water and fertilize as appropriate. When fertilizing, the application amount of nitrogen fertilizer should be controlled to prevent excessive nitrogen and cause the plant to grow. In the flowering and fruiting period, it is necessary to coordinate the balance between vegetative growth and reproductive growth of crops, prevent excessive vegetative growth and poor fruit setting, and appropriately control vegetative growth with growth regulators.
5, remedial measures
For plants that have been grown up, they can be sprayed with 750 times solution or 1500 times solution of chlormequat; for the long-term cause of falling flowers, it can be sprayed with 40 mg/kg naphthalene acetic acid solution. 2 times.
The above is the reason for the protection of the capsicum and the prevention and treatment measures. The pepper will affect the variety and yield of the pepper, reduce the commercial value of the pepper, and have an impact on the economic benefits of the growers. The growers should always manage scientifically, master the above prevention measures, and try to avoid the growth of peppers.
