Detailed Explanation of Chili Seedling Cultivation Methods and Seedling Management Key Points
Mix field soil, farmyard manure and carbendazim and other agents into nutrient soil and spread it on the ground to make a seedling bed. Then select some healthy, undamaged seeds and soak them in warm water for 8 hours, then remove them, wrap them in gauze, put them in a plastic bag and place them in a 30-degree environment to promote sprouting. After sprouting, sprinkle a layer of water on the seedling bed, then sow the seeds evenly on it, and finally cover with a layer of soil and cover with plastic film.
Chili Seedling Cultivation Techniques:
1. Seedbed Selection
The chili seedling bed should be chosen on soil that is sheltered from the wind, has sufficient sunlight, is thick and loose, and has normal drainage and irrigation. The previous crop in the soil should not be potatoes, chili or other such crops. Then control the area according to the planting quantity. The seedling trench should not be too wide or too long, otherwise it will affect the growth of the seedlings. Then prepare the nutrient soil well to ensure sufficient nutrients and freedom from bacteria and insects. The nutrient soil is mainly a mixture of field soil, farmyard manure and carbendazim and other agents. It can not only provide nutrients for seedling growth, but also do a good job in pest and disease control during the seedling stage.
2. Seed Treatment
The main chili seedling cultivation method is sowing. Before sowing, first soak the seeds in room-temperature water for about 8 hours. The time should not be too long, otherwise it will cause serious nutrient loss and reduce the germination rate. It should not be too short either, otherwise the seeds will not absorb enough water, which will also affect germination. After soaking the seeds, drain them, then place them on a wet cloth and wrap them in a plastic bag. Then place the plastic bag at a temperature of about 30 degrees to promote sprouting. During sprouting, the seeds need to be turned appropriately every day so that they are heated evenly. After about 5 days, when about 75% of the seeds have broken white, sowing can begin.
3. Timely Sowing
Before sowing, we should first water the seedling bed sufficiently, and sow only after the water has completely seeped into the soil. The sowing method for chili is generally broadcast sowing. When broadcasting, spread the seeds comprehensively and evenly on the seedling bed to promote uniform emergence. After broadcasting, mix Miaojundi and other agents with soil to cover the seeds well. This prevents diseases such as damping-off during the chili seedling stage. Also cover with a layer of nutrient soil about 1 cm thick, then cover with a layer of plastic film. This improves the heat preservation and moisture retention capacity of the seedling bed, promotes seed germination, and increases the emergence rate.
4. Seedbed Management
After sowing, control the temperature well. Keep the daytime temperature at about 22 degrees, and control the day-night temperature difference at about 10 degrees. When about 65% of the seeds have emerged, remove the plastic film. If the midday temperature is too high, do a good job of ventilation and cooling to prevent seedling scorching caused by excessively high temperature. Then control moisture well. If the soil is dry, water appropriately, but not too much. Then when the seedlings grow about two true leaves, thin them appropriately, retain strong seedlings, and increase the growth space for the seedlings. Finally, carry out hardening off half a month before transplanting, so that the seedlings adapt to the external environment and the survival rate is improved.
The above is the relevant introduction to chili seedling cultivation methods. I hope it is helpful to everyone.
