1, variety selection
It is suitable for varieties with good commercial properties, strong cold resistance and disease resistance, high yield and stable yield, low light tolerance, suitable for close planting and high quality, such as Hangjia No.1 and Cigarette No.1.
2, seedlings and cultivation methods
Open field eggplants generally use improved Yangshuo electric hotline seedlings, sowing seedlings in the middle and late January, planting in late April, and harvesting in late June.
3, sowing seedlings
3.1, seed treatment: soaking seeds for 1 to 2 days before soaking, then soaked with 1% potassium permanganate solution for 30 minutes, remove and wash clean. Then soak the seed with a seed volume of 5 to 6 times in warm water of 50 ° C to 55 ° C for 10 to 15 minutes, stir constantly, and soak for 8 to 10 hours when it is lowered to about 30 ° C. Remove the mucus from the surface of the seed with fine sand. The treated seeds are wrapped in a damp cloth and germinated at a temperature of about 30 °C. Rinse with clean water every day during germination, usually 5 to 7 days to germinate. Sow when more than 70% of the seeds are white.
3.2 Preparation before sowing: Mix 60% of the fertile paddy soil and 40% of pig manure that have not been planted with Solanaceae vegetables as the culture soil, and add appropriate amount of ternary compound fertilizer and 25% carbendazim 1 . Then make a seedbed, the bed is 1.2 meters wide, and when needed, the geothermal line is 80-100 watts per acre, then 10 cm thick nutrient soil is placed on it, and water is poured for seeding.
3.3 Sowing: Seeding is carried out in the morning of sunny days. The seeds of the budding are evenly spread on the surface of the clams, covered with 1 cm thick nutrient soil, and covered with mulch. The temperature during the day before emergence is maintained at 25 ° C ~ 30 ° C, 16 ° C ~ 20 ° C at night, the ground temperature is about 20 ° C, generally 5 to 6 days can be out of the seedlings, 70% of the emergence of the seedlings to remove the film.
3.4 Seedling management: After the seedlings are properly lowered, the room temperature is 20°C～25°C during the day and 15°C at night, and the nutrient soil is sprinkled once to the seedbed to prevent the cap from being unearthed. The two cotyledons are fully unfolded and then sprinkled once, each thickness. 0.3 to 0.5 cm. When the seedlings grow to the second leaf and one heart, the seedlings are divided. The method is to open a small ditch 10 to 15 cm apart, water the ditch, swing at a distance of 10 cm, and then cover the nutrient soil. Strengthen the heat preservation after seedlings, 28 ° C ~ 30 ° C during the day. 16 ° C ~ 20 ° C at night. When the seedling leaves begin to grow, the daytime temperature is controlled at 20 °C ~ 25 °C, and at night 13 °C ~ 15 °C, to prevent the length. The seedlings are cultivated about 10 days before planting, around 20 °C during the day and around 12 °C during the night.
4, colonization
Before planting, combined with 5,000 kilograms of organic fertilizer and 50 kilograms of compound fertilizer, the planting was carried out on sunny days, the water was poured into the ditch, and the seedlings were planted after water seepage. The plant spacing is 30-35 cm, and 2500-3000 plants are planted in acre.
5, Daejeon management
5.1 cultivating: A shallow cultivating is carried out 3 days after planting to increase the ground temperature and promote seedling growth.
5.2 Fertilizer management: Generally, no watering is required after the seedlings are delayed until the flowering. For example, a small water can be poured in the drought. In the "eyes" period, you can apply topdressing and watering, and combine 10 to 15 kg of urea and 10 kg of potassium sulfate in combination with watering. When the eggplant is fruit-bearing, water is poured every 5-7 days, and the fertilizer can be traced every 3 days, and 10-15 kg of urea is applied per mu.
5.3 Pruning snoring: After sitting on the six cigars, keep the two stalks and remove the buds under the stalks.
6. Pest control
The main disease is gray mold, 5% speed Keling WP 1500 times solution; or 75% chlorothalonil WP 600 times solution, every 7-10 days, even 2-3 times, while preventing 2-3 times Should also pay attention to the prevention and treatment of viral diseases. The main pests are aphids and thrips, which can be controlled by 10% good winter 1000 times liquid or 20% cockroach emulsifiable oil 800 times liquid; the red spider can be controlled with 73% gram emulsifiable concentrate 2000 times liquid.
