Key points of green pepper sowing and seedling raising in summer

Green pepper belongs to the plant kingdom, dicotyledonous class, chrysanthemum subclass, Solanaceae. And red chili are collectively referred to as chili. The fruit is a berry. There are many aliases, big pepper, lantern pepper, persimmon pepper are its names, because it can bear sweet berries, also known as sweet pepper, vegetable pepper. Annual or perennial herb characterized by large fruit, less spicy or even not spicy at all, eaten as a vegetable rather than as a seasoning. Because it is green and bright, the newly cultivated varieties also have a variety of colors such as red, yellow, purple and so on, so it can not only form a dish of its own, but also is widely used in side dishes.

The flesh of green pepper is thick and crisp and rich in vitamin C. Green fruit contains 93. 5% moisture. About 9%, carbohydrates about 3. 8%, red ripe fruit contains up to 460 mg of vitamin C. Can be cold, fried, cooking, stuffing, pickling and processing cans, candied fruit.

The suitable temperature range for green pepper is 15-35 ℃, the suitable temperature range is 25-28 ℃, and the germination temperature is 28-30 ℃.

Green pepper for water conditions: like moist, afraid of drought and waterlogging, require the soil to be moist without stagnant water.

Green pepper for light conditions: light requirements are not strict, light intensity requirements are moderate, light 10-12 hours a day, which is conducive to blossom and fruit. The growth and development of green pepper needs adequate nutritional conditions. For every 1000 kg of green pepper, 2 kg of nitrogen, 1 kg of phosphorus and 1. 45 kg of potassium are needed. 45 kg, but also need the right amount of calcium fertilizer. For the requirements of the soil, the wet sandy loam is better, the soil pH should be neutral, and the soil can also be slightly acidic.

Key points of sowing and raising seedlings of green pepper in summer

Put the seeds in the sun for 3 days before sowing, then soak the seeds with warm water or medicine for disinfection. Soak the seeds in warm soup, soak the seeds in clean water, then soak them in 55 ℃ warm water for 15 minutes; soak the seeds in clear water for 2 hours, then soak the seeds in 75% chlorothalonil 800 times solution for 20 minutes, scrub them with clean water. After disinfection, the seeds were germinated in the environment of 25 ℃ and 30 min, and sown when 70% of the seeds were white.

The nursery bed should choose the fields that are sunny, fertile and loose, and have not planted eggplant fruits and vegetables in 3 years, smooth and fine before sowing, and then disinfect the soil with carbendazim or dimethazone, and apply sufficient basal fertilizer 10 minutes and 15 days before sowing.

Usually sow seeds in the first and middle of December, using 50 grams per mu. Before sowing, the nursery bed should be watered with sufficient water, the seeds should be evenly sowed on the seedbed and slightly compacted with a flat plate, so that the seeds are fully bonded with the soil, then sprinkle 5% of the thin fat water, and then cover the seedbed with 0.5 million centimeters of nutritious soil, then cover the seedbed with film or build a small arch shed to keep warm and moisturize. Remove the mulch when 30% of the seeds emerge. After finishing the seedlings, 1 Mel was applied twice, and 5% clear dung water was applied once after the seedlings and before the seedlings were transferred, and the seedlings should be ventilated in the seedling stage. Seedling stage management is mainly to control the growth of seedlings, to avoid the bed soil is too wet, general nutrition soil is not white, do not water, to water thoroughly, generally in the sunny afternoon watering, according to the growth of seedlings can be combined with watering urea or compound fertilizer.

When the seedlings had 3 leaves, the seedlings were planted with medicine and soil on a sunny day with a cold tail and a warm head, and watered at the same time. The seedlings were properly refined 4 days before the pseudo-planting, and the day temperature was 19-25 ℃ and the night temperature was 1315 ℃. After pseudo-planting, the small arch shed is covered with heat preservation and moisturizing for 4 ℃ for 5 days, and the temperature in the shed is kept at about 28 min. Spray 75% chlorothalonil 800 times or 70% mancozeb 800 times after fake planting to prevent disease. After returning the seedlings, the temperature in the greenhouse should not be higher than 25 ℃. The seedlings should be refined about a week before planting, and the night temperature should be 13 ℃. The moisture content should be controlled and the ventilation rate should be gradually increased. During the planting period, the seedlings generally had 12 true leaves and began to branch, with several buds, strong plants, thick mesophyll, thick green leaves, well-developed roots, no diseases and insect pests, and not tall feet.
