How to prevent the capsicum from falling

There are many reasons for the falling of the peppers, both physical and pathological.

Pepper likes air drying and soil moist environment, such as high temperatures (more than 35 degrees), that affect pollination, fertilization, but also easily lead to plant leggy, weakening the assimilation of plants, increased respiratory consumption, causing ovary withering, filament shrinkage , Resulting in falling flowers and falling fruit, or encounter rainy days for a long time, so that the lack of light, the temperature dropped (below 15 degrees), will also affect pollination and pollen tube elongation, resulting in falling.

Droughty soil, lack of moisture, and large amount of air evaporation will also inhibit the plant's demand for fertilizer and water and cause fruit drop and fruit drop. Excessive water content and poor permeability may hinder root respiration, growth and development, and may even cause root failure.

Excessive use of nitrogen fertilizers results in leggy plants, which lose balance in their vegetative growth and reproductive growth, and cause flowering and fruit nutrient deficiencies or nutritional disorders in peppers to cause flowering and fruit loss. Planting too densely, resulting in poor ventilation, insufficient light, weakened photosynthesis, and poor male flower development, will cause the first two layers of flowers and fruit to fall off. So, how to prevent peppers from falling? The main measures are as follows.

Rotation

Choose disease-resistant and disease-resistant varieties, plant healthy seedlings without disease and pests, plant root-broken leaf seedlings without planting, rational dense planting, improve ventilation conditions, and regulate the microclimate in the field so that the plants have a good growing environment.

Strengthen management

Shed peppers should be ventilated and ventilated. Ventilation should be increased during the flowering stage. The temperature in the greenhouse during the day should be kept at 25-28°C, and the temperature should be kept at 15-18°C in the evening, and the minimum flowering period should be 15°C. The shed promotes watering under the membrane and does not flood the water. Through scientific cultivation, improve the plant's resistance to stress.

Strict control of fertilizer

Before the fruit is not set, the fertilizer is not watered to control the vegetative growth and promote reproductive growth. When topdressing fertilizer, phosphorus and potassium fertilizers should be added to reduce the amount of nitrogen fertilizer. Into the flowering period and fruit setting period, the fruit rapidly expands and the application amount of nitrogen, phosphorus and potassium should be increased.

Keep humidity

Chili hi soil is moist, generally requires air humidity of 55-65%, soil moisture of about 15%, if higher than 18% will affect the root development and plant growth, but enter the full fruit period should keep the soil moist.

Pest control

The main diseases of pepper are virus disease, anthrax, and cotton rot. Virus disease can also cause the plants to shrink, and they cannot grow in branches, which seriously affects the yield.

Virus disease caused by aphids should thoroughly control aphids as soon as possible and destroy them at the spotting stage. It can be controlled by imidacloprid, dimethoate, and dichlorvos to reduce the spread of viral diseases; aphids can be controlled by a moth killer or lime sulfur. Virus disease can be controlled by virus A, disease and disease prevention, and other diseases such as anthrax, cotton rot, etc. can be controlled by pharmaceuticals such as Prokl, Suckerling, Prodigin, Carbendazim, Thiophanate-methyl and other agents. The utilising of capsaicin can enhance the plant's resistance to pests and diseases.

In addition to the above measures, hormonal treatment can also be used, such as the use of anti-dropping flowers, etc., can also play a role in preventing falling flowers.
