The pre-growth stage of pepper is the germination stage, which is unearthed about 5-8 days after accelerating germination and sowing, and the first true leaf appears about 15 days, and the seedling stage is from I stage to budding 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.
1. Seed treatment: Generally, seedlings are raised from vernal equinox to Qingming. The pepper planting base in Tieling City exposed the seeds in the sun for 2 days to promote after-ripening, improve the germination rate and kill the germs carried on the surface of the seeds.
2. Sowing: After the seedbed is completed, water is poured on the soles of feet, then a thin layer of fine soil is sprinkled, seeds are evenly sprinkled on the seedbed, and then a layer of fine soil with a thickness of 0.5 ~ 1 cm is covered, and finally a shed is covered for moisture preservation and heat preservation.
3. Seedbed management: After sowing, the daytime temperature is 25 ~ 28 degrees, and the ground temperature is about 20 degrees. Seedling can emerge in 6 ~ 7 days. After 70% of the seedlings are arched, 0.5 cm thick fine soil should be sprinkled on the seedbed under the condition of no water on the leaves. Keep moisture by sealing the joints to prevent the roots of seedlings from being exposed. The seedbed should have enough water supply, but the soil should not be too wet. When the pepper is 5 cm high, the seedbed should be ventilated and adjusted. Ventilation should be flexibly controlled according to seedling growth and weather temperature. Seedlings can be tempered in the open air 10 days before planting. The hardening of seedlings should be done step by step, and must not be done in one step.
In order to make the pepper grow better, the pepper planting base used the marine silkworm fungus agent. It can not only improve the absorption of nutrients in the soil environment by pepper, but also make the nutrient supply of pepper tend to be reasonable, enhance metabolism, promote the balanced absorption of macro-elements and trace elements, and make the nutritional components more coordinated, thus improving the quality of pepper.
