What are the precautions for the solanaceous vegetable seedlings? Solanaceous vegetables include tomato, cherry tomato, eggplant, pepper, sweet pepper, physalis, melon, tomato, and sylvestris, and in the process of seedling cultivation, in addition to In addition to temperature and humidity, water and fertilizer management, it is also necessary to manage lighting, ventilation, etc. The specific small series will be explained in detail below.
First, the technology of seedling vegetable cultivation
1. Temperature control: After the emergence of the solanaceous vegetables, temperature management should be done, and the night temperature should be kept above 14 degrees, and the daytime temperature should be kept below 30 degrees.
2. Moisture control: Watering the solanaceous vegetables is better with water that has been placed in the shed for 1-2 days, so that the temperature difference between the seedlings and the water can be reduced. At the same time, it is necessary to control the watering. When the soil is dry, it can be watered, but it can be watered several times. If the soil is always wet, it can cause diseases such as stagnation and disease. Another point to note is that overheating and too much moisture can cause stems and leaves to turn black and rot.
3. Illumination control: The cotyledons need to be illuminated after the cotyledons are opened, so in winter, the vegetable seedlings should be placed in a place with sufficient light.
4. Ventilation control: At the seedling stage of the solanaceous vegetables, attention should be paid to ventilation. When the solanaceous vegetables have been in a sultry state, the plant's breathing will be hindered, resulting in the plant hypocotyls growing and the plants becoming long seedlings, affecting the seedlings. the quality of.
Second, the attention of the eggplant and vegetable electric heating line seedlings
1. Seeding method: The substrate is made of peat soil, fine soil and organic fertilizer, and mixed thoroughly according to the ratio of 4:4:2. The substrate nursery seedlings are placed in the seedbed, and the water is poured and used. After 4 hours of sowing, each seed was sown, covered with 0.5 cm thick cover seed mud, covered with a small arch shed, and heated to warm the line. It should be noted that the electric heating needs to be switched according to the weather. When the weather is good and the light is good, the temperature in the arch shed may reach 30 degrees or above. Therefore, the power can be turned off after 9 o'clock, and the power is turned on before 3 pm, and the arch shed does not need to be opened. Turn on the power when it is cloudy or when the temperature is low.
2, after 5-6 days of sowing, when the budding reaches 50%, the covered mulch can be removed when the light is weak in the morning and afternoon; when the topsoil is dry, the storage water is sprayed with a sprayer to properly replenish the water; After opening, you can use a watering can. At the same time, we must do a good job of lighting and ventilation.
3, pay attention to proper training of seedlings, which is conducive to obtaining robust and high-quality seedlings.
