Pepper cultivation technology

[ Agricultural Products Network] What should I pay attention to when cultivating peppers ? What are the requirements for growing pepper ? The temperature requirement of pepper is between the eggplant and the eggplant . Seed germination temperature is 23-30 ° C, below 15 ° C can not germinate. Pepper seedlings require higher temperatures, lower temperatures, and slower growth. In the early days of flowering, the temperature is 20-25 °C during the daytime and 15-20 °C during the night. As a result, the soil temperature is too high, especially the strong light directly hits the ground, which is unfavorable to root growth and easily causes toxin disease and daily burnt disease.

Ground preparation fertilizer

Chilli should not be used for continuous cropping, nor can it be used in crops such as eggplant, tomato, potato and tobacco. The cultivated pepper plots should be well drained, convenient for irrigation and drainage, and require deep tillage. ZUI can do winter ploughing and leisurely frozen soil to improve soil and eliminate winter pests and pathogen spores. Before planting, the topsoil will remain larger, so that it is breathable and refreshing, which has a good effect on preventing falling flowers, falling camps and fallen leaves. Changsha vegetable farmers' requirements for planting pepper fields are “deep gully and sorghum, broken old bottom; soil is flat and water is flowing smoothly”. The width is generally 1.3-1.7 meters (continuous ditch), planting 2-3 rows. There is also a width of 2.3-2.7 meters, which is planted laterally on the raft. At the same time, 50-80 tons of fermented manure per acre, 15 kg of superphosphate, 25 kg of grass ash as base fertilizer.

Sowing seedling

The method of growing plastic small arch shed seedlings is as follows:

1 seed bed selection: the seedbed should choose north to south, high dry water, and convenient water source, and has not planted the plot of the Solanaceae crop.

2 Seedbed preparation: The seedbed ZUI is good to dig the toast in the sky, splashing a layer of human and animal waste, drying it, and covering it with a film to prevent the loss of fertilizer when it rains.

3 sowing: the bed soil is fully wetted before planting, and it is flat and flat. The width of the seedbed is generally 1.5-1.7 meters. Generally do not soak seeds and germination. Early-maturing seeds are generally sown in January, late-maturing seeds are usually sown in February-March, and 75-120 grams of planting is required for planting one acre.

After sowing, cover with a fine soil mixed with old ash or coal ash, the thickness is about 2 cm, to cover the seeds . Then watering, after receiving water, cover the mulch, ZUI is surrounded by thin bamboo rafts or bamboo pieces into a small arch frame, about 0.5 meters high, covered with film, the film is compacted with mud on the north side to protect against wind . The bricks are pressed on both sides so that the film can be uncovered at any time and the air is ventilated.

4 seedbed management: after sowing to pre-emergence, generally do not need management, found that began to emerge, should immediately remove the mulch, otherwise the formation of high seedlings. After the emergence of the seedlings, the film was uncovered at 9 am on a sunny day and the film was still covered at 4 pm. Try to ventilate as much as possible on a rainy day. It is found that the bed soil is white, and the seedlings are wilting, so watering is required, and the watering time must be at 9:00 am and 1-2 am. Two hours after watering, check again. If it is found to be still dry, it will be hydrated to make the seedlings grow consistently. Rainy days and frozen days should not be watered. Otherwise, the humidity will be too high and the bed temperature will decrease, which is prone to disease. In the snowy weather, the grass window can be covered, the grass window is covered with a film, and the electric light can be installed in the bed to protect the cold and protect the seedlings.

5 rows of seedlings: In order to make the seedlings thick and strong, the root system is developed. When the two seedlings of the seedlings appear, they need to be planted once, the plant spacing is 6-10cm, the row spacing is 12-15cm, and the rows are watered to prevent the seedlings from wilting and the seedling beds. Preparation, requirements and management are similar to the seed bed.

Colonization

The planting of pepper is suitable for soil temperature above 15 °C, and it is prematurely planted because of low soil temperature, slow growth, and falling flowers, which can not achieve the purpose of early maturity. Planting distance, early maturing varieties line spacing 40-50 cm, plant spacing 26-33 cm, l 2 per hole, late maturing varieties line spacing 66-73 cm, plant spacing 50-60 cm, 1 hole per hole. Choose a sunny afternoon planting, the morning seedbed needs to be watered to facilitate the seedlings.
