The key to raising eggplant vegetables in spring early
Appropriate sowing to promote early-onset early this year, early eggplant fruits and vegetables should be planted in early November sowing seedlings, promote early-onset strong seedlings to ensure that seedlings safely through unfavorable low-temperature period.
Improve Seeding Quality Seedlings for seedlings should use high quality varieties that meet national quality standards. The preparation of nutritious soil should meet the needs of crops. Bed soil and organic fertilizer should be fully mixed and matured, and special compound fertilizer should be mixed into nutrient soil more than one week in advance. Actively develop seedling tray seedlings, make full use of the factory-based nursery center to order seedlings for farmers, and reduce the number of traditional seedlings. Seedlings are planted with 2 seeds per pod, leaving them strong and weak when they are set.
Strengthen the temperature control of anti-freezing, early spring Solanaceous vegetables and fruits at seedling stage in the long-term low temperature stage, pay close attention to antifreeze insulation work is a key measure to cultivate strong seedlings. In terms of temperature regulation, the seedling period is mainly increased, and the seedbed temperature is increased as much as possible. The seedbed should be selected in the middle section of the greenhouse, with insulation curtains at both ends to avoid cold winds in the shed. The seedbed adopts small sheds and multi-storage covering in the middle shed, and the sunny sheds are covered with light to increase the temperature. After sowing, we pay close attention to the changes in the weather. Before the onset of the cold wave, we must close the shed film to prevent people from entering the wind when entering or leaving the area. Conditions can use the pre-heated hotline, or install air heaters in small sheds and heat up in continuous low temperature rain and snow conditions.
To prevent seedling diseases, health care seedlings greenhouse eggplant vegetables weather conditions are not suitable for seedling growth, disease resistance is weak, and the seedbed closed insulation for a long time, high humidity, easy to induce various types of seedling disease. To prevent diseases at the seedling stage, we must focus on four measures. The first is to soak seeds with warm soup or sterilize before treatment. Soaked in warm soup, the amount of water is 3 to 5 times the seed, temperature 55 °C, soaking for 10 minutes, and constantly stirring; agent treatment, with 50% carbendazim WP 500 times soaking for 1 hour. The second is disinfection of bed soil and cover soil. 50% carbendazim wettable powder 40 to 50g soil mixing per cubic meter of bed soil, 5 to 7 days stuffing film, 7 to 14 days after uncovering film; can also be sprayed with 100% formalin 1 kg of formalin can handle 4,000 to 5,000 kg of bed soil, and the cover membrane is stuffy for 5 to 7 days, and it is used 7 to 14 days after uncovering the film. The third is to control the humidity of the seedbed. In winter, the weather in clear weather lifts membrane ventilation, reduces the humidity in the greenhouse, and controls the occurrence of diseases. The fourth is to strengthen the monitoring of seedling disease. After the emergence of regular point monitoring, once the incidence of early drug control, control of disease spread, the disease control in the early stages of disease, to ensure the cultivation of disease-free strong seedlings.
