Detailed Explanation of Key Management Techniques for Sweet Pepper Seedlings

Good seedling management of sweet peppers is the key to achieving high yields and is also one of the main ways for farmers to increase their income. So how should sweet peppers be managed during the seedling stage? Let's take a look at sweet pepper seedling management techniques together with the editor below.

1. Control the temperature

Before the seedlings emerge, a relatively high temperature and humidity should be maintained. After the seedlings emerge, the degree of cooling should mainly be aimed at preventing obstruction of seedling growth. Generally, during the day it can be lowered to between 15-20 degrees, and at night it should be controlled between 5-10 degrees. After the true leaves appear, the seedbed temperature should be appropriately raised to suit seedling growth and development, with 20-25 degrees during the day and 10-15 degrees at night.

2. Strengthen light exposure

After sowing, light exposure must be strengthened, giving the seeds and plants sufficient light to ensure that photosynthesis proceeds smoothly. In order to give the seedbed sufficient sunlight and improve light conditions, while maintaining warmth, the covering materials should be removed as early as possible and put back as late as possible, extending the duration of light as much as possible. When removing the film, also prevent cold wind from blowing in directly. It is recommended to spray New High-Lipid Film to form a polymer film for warmth retention and reduce damage to the seedlings.

3. Reduce humidity

Excessively high humidity is not conducive to seedling growth and also very easily causes disease, so ways must be found to reduce seedbed humidity. Humidity can be reduced through ventilation to lower moisture and by spreading dry soil or plant ash to absorb moisture. However, when ventilating to reduce humidity, attention must be paid to keeping warm, and the weather at the time should also be considered, so as to protect the seedlings from cold damage as much as possible. Spreading plant ash can absorb water and reduce humidity, but it must be fine; after fully crushing and sieving, apply it when the seedling leaves are dry. After spreading the soil, lightly sweep the leaf surfaces with a broom so that the fine soil falls down and does not contaminate the leaves. When seedbed humidity is relatively low, appropriate watering can be done. Watering should be done in small amounts and frequently. During the rainy season, drainage should be carried out promptly to avoid water accumulation that causes root rot.
