What is the temperature of pepper seedlings?
The suitable temperature of pepper is between 15 and 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 15℃ 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. Seedlings are not tolerant of low temperature, so pay attention to cold protection. Pepper will drop flowers and fruits at 35 degrees. The optimum temperature of pepper seed seedling is 20-23 degrees. Pepper is a thermophilic crop, and the suitable temperature for pepper seed germination is that it cannot germinate when the temperature is over 35℃ or below 10℃. It takes 45 days to germinate at 25℃, and it is difficult to germinate or stop germinating below15℃/kloc-0 ~15 days,12℃ for more than 20 days. Ground temperature and air temperature are often low, and the growth is slow, so artificial warming should be adopted to prevent cold and frost. After the seeds germinate, with the growth of seedlings, the ability of low temperature tolerance will be enhanced. When seeds with more than three true leaves germinate at 25℃, they grow rapidly, but they are extremely thin. It is necessary to reduce the temperature to about 20℃ to keep the seedlings growing slowly and healthily, make cotyledons hypertrophy, which is beneficial to the differentiation of primary true leaves and flower buds. The optimum temperature of pepper seed seedling is 18-25℃. The suitable temperature for pepper seed propagation is 20-30 degrees.
