Method and time of pepper seedling raising

Seedling raising time is generally selected in the middle and late February in spring, which is very helpful for the success of seedling raising. The seedbed should be selected in a plot with high dryness, cold water, facing north and south, water source and no solanaceae crops. After sowing, the seeds should be covered with fine soil mixed with coal ash or old chaff ash, with a thickness of about 2 cm. It is advisable to cover the seeds, then water them, cover them with plastic film after collecting water, and finally enclose a small arch with thin bamboo chips or bamboo poles and cover them with film.

First, the method and time of pepper seedling.

1, the seedling raising time of pepper is generally selected in the middle and late February in spring, which is very helpful for the success of seedling raising. The seedbed should be selected in a plot with high dryness, cold water, facing north and south, water source and no solanaceae crops. It is suggested that the seedbed should be dug deep into the baked soil in dog days, sprinkled with a layer of human and animal manure, dried and covered with film to prevent fertilizer loss when it rains. Before sowing, fully wet, thin and level the bed soil. The width of seedbed is generally 1.5- 1.7 m, so it is generally unnecessary to soak seeds to accelerate germination. Late-maturing seeds are usually sown in February-March, and early-maturing seeds are generally sown in 65438+ 10, and it takes 75- 120g to plant an acre.

2. After sowing, cover the seeds with fine soil mixed with coal ash or old bran ash, with a thickness of about 2 cm. Cover the seeds, water them, and cover them with plastic film after collecting water. Finally, a small arch frame with a height of about 0.5 meters is surrounded by thin bamboo pieces or bamboo poles, and a film is covered on it. The north of the membrane is compacted with soil, which helps to prevent wind, and the two sides are compacted with bricks, which is convenient for ventilation and can be uncovered at any time.

3. From sowing to emergence, there is usually no need for management. If it is found that the plastic film needs to be removed immediately after emergence, otherwise high seedlings will be formed. After emergence, uncover the plastic film at 9: 00 a.m. on sunny days, and cover it at 4: 00 p.m., and ventilate the seedlings as much as possible on rainy days. It is found that the seedlings are wilting and the bed soil is white, so it needs to be watered in time. The watering time is set at 9 am and 1-2 pm. Check after watering for two hours. If it is found that some parts are still dry, it is necessary to replenish water to make the seedlings grow consistently. In rainy and freezing days, due to excessive humidity, the bed temperature decreases, which is easy to cause diseases. On snowy days, electric lights can be installed in the seedbed to protect the seedlings from the cold, and a film can be covered on the grass window.

4. In order to make the seedlings robust and the roots developed, when two true leaves appear in the seedlings, it is necessary to follow them once, with the row spacing of 12- 15cm and the plant spacing of 6- 10cm to prevent the seedlings from wilting. The requirements, preparation and management of seedbeds are similar to those of seedbeds.

Second, the field management methods of pepper planting

65438+ intertillage should combine soil cultivation with weeding.

2. After planting, it is necessary to apply seedling fertilizer in sunny days, and the dosage should not be too thick or too much each time, otherwise it is easy to delay flowering and fruiting, resulting in virtual growth. When 1 and layer 2 bear fruit, more fertilization should be applied to promote fruit growth. After fruit picking, it is required that the soil has enough fertilizer and water, so that plants can bear fruit and grow normally. During irrigation, the irrigation time must be determined according to the weather forecast, and the irrigation depth shall not exceed three quarters of the furrow. It is recommended to do it at night or in the early morning, and the washing should be carried out urgently.

3. As fresh peppers, most green fruits can be harvested, and red fruits can also be harvested. Red ripe fruits, as dried peppers, must be harvested in time to prevent the growth and fruit of plants from being affected.

4. The method of combining seed collection with fruit selection is to select standard plants in the field according to the characteristics of varieties and mark them as seed collection plants. The first layer of fruit should be harvested as soon as possible, leaving 2-4 layers of fruit as seed fruit. After the seeds and fruits turn red, they should be harvested, and then the fruits with the characteristics of this variety should be further selected. The picked seeds and fruits should be spread in the shade, ripened for 5-7 days, cut, taken out, dried and stored.
