Pepper flowers are hermaphroditic and have smaller flowers. The flowers of sweet pepper are bigger than those of hot pepper, and the flowers grown under mild conditions are bigger than those grown under hot conditions. Corolla is white or green-white, calyx is bell-shaped at the base and has five teeth at the top. Corolla base is connate, and flowers are solitary or clustered at branching points. It belongs to conventional outcrossing crops and insect-borne flowers, and the outcrossing rate is about 10%. When the plant grows normally and the environmental and nutritional conditions are suitable, it is beneficial to the normal formation of flowers. When the nutritional and environmental conditions are poor, it is easy to form deformed flowers (short-column flowers as shown in the figure below), which is not conducive to fruit setting. In pepper cultivation, too much watering makes the seedlings grow too vigorously, the quality of flowers is poor, and it is easy to drop flowers; If you water too little, the plants will grow weakly, which will also affect the quality of flowers and obviously affect flowering and fruit setting. Growth habit of pepper.

The early growth stage of pepper is the germination stage, which is usually unearthed about 5-8 days after germination and sowing. The first true leaf appears about 15 days until the bud is the seedling stage. The flowering period is from the first ear to the door pepper. The fruiting period is from fruit setting to seedling drawing. The suitable temperature of pepper is between 15-34 degrees. The suitable temperature for seed germination is 25-30℃, and it takes 5-7 days to germinate. When the temperature is lower than 65438 05℃ or higher than 35℃, the seeds will not germinate. The seedling stage requires high temperature, 25-30 degrees during the day, and 15- 18 degrees at night is the best. Seedlings are not tolerant of low temperature, so pay attention to cold protection. If the pepper is 35 degrees, it will drop flowers and fruits. Pepper has strict requirements on conditional moisture, and it is neither drought-tolerant nor waterlogging-tolerant. I like dry air conditioning. Edible value of pepper. The content of vitamin C per 100 grams of pepper in diet therapy is as high as 198 mg, ranking first among vegetables. Vitamin B, carotene and minerals such as calcium and iron are also rich. Medical experts believe that pepper can relieve cold pain in chest and abdomen, stop dysentery, kill parasites in stomach and abdomen, and control heart disease and coronary atherosclerosis; It can also stimulate oral mucosa, cause gastric peristalsis, promote saliva secretion, enhance appetite and promote digestion.
