How to grow eggplant seedlings? Methods and timing explained in detail
SummaryEggplant seedling growing methods: choose high-quality varieties that are disease-resistant and suitable for storage and transport, purchase good seedling equipment, then soak the seeds to promote germination before sowing. During the seedling stage, temperature and humidity should be well controlled. After 60-80 days of emergence, select strong seedlings, strengthen insulation measures, and pay attention to preventing stiff seedlings and old small seedlings, and preventing diseases such as damping-off during the seedling stage. Timing for growing eggplant seedlings: generally 80-90 days before planting. The specific planting time depends on soil temperature and the cultivation environment.
I. Timing for growing eggplant seedlings
To determine the timing for growing eggplant seedlings, generally first determine the planting time based on the cultivation environment and soil temperature, then count back 80-90 days from the planting time to get the sowing and seedling growing time. Generally, for early spring planting, planting can be done when the soil temperature at a depth of 10 cm is stably above 13 degrees Celsius. If production is carried out in a greenhouse using sunlight, generally the soil temperature must reach above 15 degrees Celsius, and the air temperature must reach above 20 degrees Celsius before planting.
II. Methods for growing eggplant seedlings
1. Selecting varieties
Generally choose varieties that are tolerant to low temperatures, tolerant to weak light, disease-resistant, and suitable for storage and transport.
2. Seedling equipment
Equipment such as greenhouses can be used, and in summer and autumn, insect prevention measures and shading measures should be provided.
3. Sowing
Eggplant seed coats are relatively thick, so the seeds need to be soaked to promote germination, and this process takes a long time. If it is summer or autumn, disinfected seeds can be used directly for sowing. After preparing the bed soil and medicated soil, watering and sowing can be carried out. Generally, before sowing, the soil should be thoroughly watered with warm water, then medicated soil should be scattered on top. After sowing, cover with plastic film. If sowing in winter or spring, cover with plastic film; if sowing in summer or autumn, cover with rice straw. When most seedlings have pushed through the soil, the covering should be removed.
4. Seedling stage management
During the seedling stage, temperature and humidity should be well controlled. If the bed soil is moist, cooling and dehumidifying should be carried out immediately after the seedlings recover. When separating seedlings, using nutrient pots is more convenient. After separating seedlings, temperature and light management should be carried out. Generally, the seedbed should not be watered too dry or too wet. When organic fertilizer is sufficient, no additional fertilizer is needed. One week before planting, temperature and humidity should be reduced to harden the seedlings.
5. Standards for strong seedlings
Generally after 60-80 days, strong seedlings can be selected. At this time, the seedling body can usually grow to about 15 cm, with 7-9 true leaves. The leaf shape and color should be qualified, and the stems, flowers, and roots should all grow well. The whole seedling only needs to be free of pests, diseases, and damage.
6. Disease prevention and control
Disease prevention and control includes preventing freezing, preventing stiff seedlings and old small seedlings, and preventing damping-off during the seedling stage. To prevent and control these diseases, generally the insulation effect should be enhanced, and low-temperature-tolerant varieties should be selected. Heating measures can also be used, or insulation measures such as covering with small arch sheds can be applied. Water and temperature management should also be strengthened. During the seedling stage and young seedling stage, water and soil temperature should be controlled as much as possible, diseased seedlings should be discovered and handled early, and medicated soil should be used to disinfect the seedbed.
