First, the seedling time of pepper
Pepper is cultivated in spring, usually sown in June 5438+10-February, and the seedling age is 90 days-1 10. Sow in time according to the planting period. Seedling raising is an important stage of pepper growth and development, as well as an important period of vegetative growth and reproductive growth, which has a great influence on the yield and quality in the later period.
Second, the pepper seed treatment method
1, seed soaking with chemicals
In order to control anthracnose and bacterial spot disease, the seeds can be pre-soaked in clear water for 5 -6 hours, then soaked in 1% copper sulfate solution (copper sulfate 1 part, 99 parts of clear water) for 5 minutes, then taken out, washed with clear water and germinated; Seeds can also be soaked in formalin (40% formaldehyde)/0/50 times solution of kloc-0/5 minutes, and then washed to accelerate germination.
2. Soak seeds in traditional warm soup.
Water consumption is five times that of seeds. Pour the seeds into warm water and stir immediately. After the water temperature drops to 30 degrees, soak for 8 hours. The method has bactericidal effect on pepper scab and Sclerotinia sclerotiorum.
Third, the formula of accelerating germination of pepper seeds
Rub the soaked seeds with mucus, then wrap them in wet cloth and put them in a warm place to accelerate germination. Temperature changes should be used to accelerate germination, that is, 28-30 degrees 16- 18 hours per day, 16 degrees -20 degrees for 6-8 hours.
In the process of accelerating germination, it is necessary to strengthen the turning and scrubbing of seeds, turning them two or three times a day, or adding wet sand equivalent to 3-4 times the amount of seeds in the container to accelerate germination and increase oxygen to meet the needs of pepper seed germination.
Pepper seeds can germinate in 4-5 days at 28 -30 degrees, and it takes more than 7 days below 25 degrees. When more than 80% of the seeds germinate, lower the temperature to 10 degrees before sowing for low-temperature exercise and get ready for sowing.
