1, enhance lighting. Insufficient light is the leading cause of falling and falling flowers. You can install dedicated fill lights in the shed, fill light during the daytime to open the shed, and add a light curtain to the back wall of the shed to increase the efficiency of scattered light. Enhances the photosynthesis of peppers. In particular, timely management of pruning should be carried out. First, loose the ropes of peppers to increase the opening angle of the pepper branches, strengthen the pruning, remove excessive branches, especially the inner litchi, increase the light area of ​​the leaves and reduce nutrient consumption. The role to improve the fruit set rate of pepper.
2, reduce the humidity. The flowering and pollination of vegetables also requires humidity. Even if there is little ventilation in the ceiling, the humidity in the greenhouse is too large, which can easily lead to poor development of pepper pollen and reduced activity, and pollination cannot be completed. Therefore, even in cloudy days, it is necessary to pay attention to the interval of 2-3 times during the period from 12 noon to 2 o'clock in the afternoon. The tuyere is 7 to 10 centimeters in diameter, and each exhalation time can be about 15 minutes. In this way, the humidity in the booth can be reduced as much as possible without significantly affecting the temperature in the booth.
3, artificial grant pollination. The vegetable grower can take measures to promote more pollen sticking to the stigma of the pepper pistil and ensure pollination is completed.
4, leaf nutrition. Falling fruits and falling fruit are also inextricably linked to inadequate nutrient supply. Even in cloudy days, farmers can increase the growth of peppers by adding fertilizer to the leaves. Foliar spraying foliar fertilizers, such as boron-containing zinc-containing foliar fertilizers and 1000-fold times the number of nucleotides chitin 1000 times, to supplement the energy of pepper, improve plant resistance, thereby reducing the excessive consumption of nutrients caused by falling The amount of fruit drop.
5. Apply a plant growth regulator. When the peppers fall and fall, they should be sprayed with naphthalene acetic acid and other plant growth regulators to protect the fruit, but the amount used should not be too large, the amount should be controlled at 30-40 mg / kg. After using naphthalene acetic acid, the leaves of pepper plant will appear 2-3 days of curved leaves, will recover on their own after a few days
Another benefit of vitamins for the human body is that it can help the growth and development of the human body to operate normally, especially for teenagers, vitamins are one of the essential nutrients in the growth process. For example, vitamin D can well adjust the metabolism of some trace elements in the human body, and can also promote the absorption of calcium by the human body, maintain bone health, and maintain a balance between the blood phosphorus level and the blood calcium level in the human body.
