Solanaceous vegetables (including eggplant, pepper, tomato) and cabbage are cultivated in small greenhouses in early spring. The nursery is in seedling stage and seedling stage in February. This period is the key stage for the cultivation of age-appropriate seedlings. Temperature control 3 to 5 days before seedling separation, seedling temperature should be appropriately reduced to consolidate seedlings, generally eggplants maintain a daily temperature of 20°C～25°C, nighttime temperature 12°C～15°C, cabbage daytime temperature 12°C～16°C, night temperature Not less than 8°C; try to extend the lighting time within one week after seedlings, warm up during the day, and cover the insulation of the opaque covering in the evening. Solanum fruits maintained at a temperature of 26°C to 28°C during the day, not less than 15°C at night, 20°C during the day in the cabbage, and 10°C during the night; after sowing, they were planted and the daytime temperature of the eggplant was controlled between 22°C and 28°C. , nighttime 14 °C ~ 16 °C, cabbage daytime 20 °C, night 8 °C ~ 10 °C. In eggplant, the eggplant requires the highest temperature, the upper temperature limit should be taken, and the tomato temperature should be the lowest. The lower limit should be taken, and the temperature of the pepper should be taken. For cabbage, the temperature must not be lower than 8 °C, with 10 °C or more being the best. Light regulation should extend the light receiving time as much as possible, increase light, and expedite the early release of the cover grass every morning; the cold weather must be exposed and the weather must be exposed at an early date. It must not be exposed for a few days in a row. In order to prevent the seedlings from wilting, they can be shaded; even when the sky is clear, the seedlings see light from small to large and gradually increase. Ventilation management points before seedlings, should be properly strengthened seedbed ventilation, cooling and hardening seedlings; sub-seedlings to be carried out on a sunny day without wind; 5 to 7 days after seedlings are not ventilated, in order to warm the temperature, promote slow seedlings; Increase the amount of ventilation, and pay attention to regulate the temperature, prevent seedlings leggy; cloudy, especially in cloudy days and rain and snow days are generally not ventilated, after seedlings, before planting can be a large expelling. Fertilizer management generally does not top-dressing fertilizer this time; watering should pay attention to seedling water and block water; seedlings after the appropriate water control, in order to promote the development of the roots, bauxite to keep dry and see wet; sub-seedling and post-emergence water Adequate, when the temperature is high, the humidity can increase, and when the temperature is low, the humidity should be reduced; The management of special weather must be overcast and cloudy: we must uncover the rice dumplings every day, cover them as early as possible, or open them shortly before and after noon, and increase the night-time insulation materials; do not ventilate or ventilate for a short time. Snowy days: Cover the opaque cover with a film, and remove the snow in time. In continuous cloudy snow weather, it is necessary to promptly sweep snow, exposing it in the afternoon, or cover it with the cover. It cannot be uncovered for several days in a row. Rainy days: If it rains during the day, it is not necessary to cover the floodwaters to make the rain fall through the membrane. In the evening when it rains, it must be covered and a layer of film should be added. In the rainy days, it cannot be covered.
