Seedling raising method and time of Autumn Pepper

Pepper is cultivated in the north and south of China, usually planted as a vegetable or condiment, its nutritional value is rich, but also has important medicinal value. We all know that peppers are grown mostly in spring, but there are also plants that are grown in autumn. So, autumn pepper seedling method and time is what?

1. Seed bed selection

To choose sufficient sunshine, fertile soil, water conditions are good, the previous crop did not plant pepper, cabbage, eggplant, tomatoes, potatoes plot for seedbed. Because these crops belong to a family, the same disease, continuous cropping susceptible disease. Seedbed area is 1% of field area. After the seedbed is selected, water is poured into the sole before sowing.

2. Soaking seeds

sun that seeds for 2 day before sowing, soaking in clear water for 3-4 hours, soak in 10% trisodium phosphate 1000 times aqueous solution for 10 minutes, washing with clear water, and soaking in warm water at 55 DEG C for 10 minutes. To constantly stir, and at any time to maintain warm water temperature of 55℃, remove germination 24 hours to be sown.

3. Soil preparation and sowing

300kg of decomposed high-quality coarse fertilizer (or 50kg of decomposed chicken manure), 1.5kg of urea, 5kg of calcium superphosphate and 15kg of plant ash are applied to the irrigated seedbed plot in yellow stubble. After the fertilizer is evenly spread, it is shallowly turned 15 cm, raked and leveled, and made wide and high ridges, which is conducive to early sowing, planting and root development. 7- 10m long, 1.2m wide, 0.85m wide, 0.4m spacing (groove width), 0.1m deep. Part of the fine soil from the ditch is temporarily piled up for soil restoration. Sow seeds immediately after the bed is ready. 200 grams of dried seeds are evenly scattered on each ridge surface, covered with soil and covered with 0.9 meters wide plastic film. The film surface should be tightened and flattened, and both ends should be tightly compacted. After the plastic film is covered, a small arch shed is made with plastic film on the ridge, and the shed height is 0.5-0.6 meters. Soil preparation, sowing and film covering should be done quickly to prevent moisture loss. Can also be carried out in plastic shed or solar greenhouse small arch shed seedlings.

4. Seedbed management

① Temperature: The temperature is controlled at about 25℃ during the day; about 12-15℃ at night. When 60-70% seedlings emerge, remove the mulch. When the temperature rises at noon, pay attention to let the air cool down to prevent burning seedlings.

② Moisture: The soil moisture for seedling cultivation should be small. When seedlings 2-3 true leaves, such as soil drought available watering can spray water. 4-5 If the leaves are dry, the furrow can be filled with water, so that water slowly seeps into the soil in the border, and irrigation should be thoroughly to reduce the number of irrigations.

③ Thinning seedlings: When seedlings have 1-2 true leaves, they should be thinned, weak and strong, weeds should be removed, and crowding should be prevented. Plant spacing 3-4 cm, each ridge leaves about 17000 seedlings, can be planted in 2 mu field.

(4) seedling training: 15 days before planting (mid-April), the seedlings were trained at the top of the small arch shed to adapt to the external environment gradually and improve the survival rate of transplantation.

Autumn pepper seedling time is generally in September, which is the appropriate temperature conducive to pepper winter stubble.
