1 Cultivate strong seedlings: Open field cultivation includes spring sowing and summer sowing. Spring sowing eggplant seedling period is in the winter season, generally in the greenhouse from late January to early February. After 1 month, the seedlings are planted in Yangshuo, or directly in the Yangshuo from mid-February to early March. The seedling age is about 90 to 100 days. Summer sowing eggplants are generally planted in the open field from late April to early May, and the varieties with heat resistance, moisture resistance and disease resistance are selected. In the initial stage of nursery, a small arch shed is placed on the surface of the nursery. It can prevent rain and sun exposure. It is ventilated after emergence. When the two leaves are sandwiched, the seedlings are divided once and the seedling age is about 60 days.
The eggplant seedling method and seedling management are basically the same as those of tomato, which can be referred to, and note that: 1 eggplant germination is slower than tomato, germination time is 1 to 2 days longer than tomato; 2 in the process of seedling, the temperature is slightly higher than tomato 2~3 °C; 3 eggplant root system is early in nature, poor regeneration ability, so when seedlings or transplants, try to bring more soil to avoid root damage.
2 Fertilization on the site, timely transplant: Eggplant avoids continuous cropping, avoiding continuous cropping with Solanaceae crops such as tomatoes, peppers and potatoes. Spring sowing eggplant can be used for wintering or wintering vegetables; medium-ripening or autumn-cultivated, can pick up spring vegetables, such as cabbage, water radish, spinach and so on. After the final frost from the end of April to mid-May, the film is colonized and can mature early. Most of the summer sowing eggplants are planted after the wheat harvest, and the vegetable area can be connected with early-ripening cabbage, cauliflower, garlic and other mantles, which is called “wheat eggplantâ€.
Before planting in spring, 75,000 to 90,000 kilograms of fermented organic fertilizer per hectare, 400 to 600 kilograms of phosphorus and potassium compound fertilizer, ploughing and leveling to make sputum, ditching or digging a hole to plant seedlings. When planting, it is best to mix the biological fertilizer and the soil well, sprinkle it into the planting hole, and plant 50,000 plants per hectare, and water it after planting.
3 skill application of top dressing: timely planting after planting, improve ground temperature, promote slow seedlings. After the seedlings are not dry, do not water, if it is dry, you can pour a small amount of water, and cultivate 2 to 3 times in time, carry out seedlings, promote the development of roots in depth, and lay a foundation for the plant to expand the absorption area and flowering results. At the end of the "eyes" period, the seedlings are finished. In combination with watering, 15,000 kg of manure is applied per hectare. This time, fertilization should not be too late or too early. If it is too early, it will be easy to be mad. If it is too late, the skin will be purple, which will affect the development of the fruit and the subsequent branching results. When the eggplant and the four mothers are flowering, it is also the time when the eggplant needs the most fertilizer and water. Generally, water is poured every 5 to 6 days to keep the soil moist. In combination with watering, the manure or the decomposed cake fertilizer is 15000 kg per hectare or nitrogen and phosphorus. Potassium compound fertilizer 225 kg. In the next time, the water will be washed once, and the fertilizer will be alternated once, that is, the fertilizer will be chased once every 15 days, and the total fertilizer will be 8 to 9 times. In the mid-late ripening, at the peak of the results, 0.2% urea or 0.3% potassium dihydrogen phosphate can be used for foliar spraying. It can also be diluted with water by biogas liquid fertilizer, which is beneficial to plant growth and fruit setting.
If there is magnesium deficiency in the soil or excessive application of nitrogen and potassium fertilizer, the balance between elements is destroyed, and the root system cannot absorb magnesium normally and induce magnesium deficiency. When the soil is deficient in magnesium, dolomite or calcium magnesium phosphate can be added to the base fertilizer. In the initial stage of magnesium deficiency, it is necessary to promptly apply 405 kg of magnesium sulfate per hectare or spray 0.1% to 0.2% of magnesium sulfate on the foliar surface once a week for 3 times.
During the growth period of eggplant, the temperature is too high or too low, the light is insufficient, the malnutrition, and the soil suddenly dry and wet cause the flowers to fall. Therefore, the rainy season should pay attention to drainage and prevent damage, and avoid excessive application of potassium fertilizer.
Eggplant is served with tender fruit. It usually takes about 20 to 25 days from flowering to tender fruit ripening. It should be harvested and listed in time. The eggplant should be taken early to facilitate future branching and fruit setting. Harvested in the morning, the fruit is fresh and shiny, and the value of the product is high.
