Qishan mini-type eggplant cultivation techniques
Early spring cultivation techniques Cultivation facilities and time are generally cultivated using facilities such as solar greenhouses, plastics, small and medium sheds, windbreak impotence, etc., which have somewhat poorer insulation properties. The seeding period for the seedlings in the electrothermal hotbed is early December, and the seedling age is 70 days, and planting in mid-February. When plastic greenhouses are used for cultivation in North China, the seeding period is about mid-December, seedling age is about 110 days, planting in the middle and late March, and harvesting in early May. When using seedbed nursery, the sowing date is mid-January, seedling age is about 70 days, and plants are planted in mid-late March. Using wind-blown Yangshuo cultivation, the seeding period for raising seedlings in Yangshuo was at the end of November, planting at the end of February and harvesting at the end of April. When using small plastic sheds to cultivate, the sowing and planting period covered with grass rakes is ahead of the plastic shed, after windbreak impotence, and when grass covered rakes are covered, it is 7 to 10 days later than plastic sheds.

When cultivated in a solar greenhouse where insulation properties are somewhat inferior, North China uses solar greenhouses or Yangshuo for breeding. The sowing date is early November, and the seedling age is 110 days to 120 days. The planting will be carried out in mid-February and harvested in mid-to-late April.
Seedlings in order to ensure the normal development of seedlings, the best use of electric hotbeds. The power density of the electric hotbed in North China is preferably 100 watts per square meter. Seeds should be treated 5 days to 7 days before sowing. Usually soaked with warm soup at 50 °C ~ 55 °C; or soaked with 1% formalin solution for 15 ~ 20 minutes, then wash with water. Disinfect and soak for 4 to 6 hours. After dipping, remove and dry the surface moisture, wrap it with gauze, place it in a constant temperature box, keep it at 30°C during the day and 18°C ​​during the night, and use the warming and germination method to germinate. About 5 days to 7 days to sprout.
The days of sowing and sowing should be selected in the morning. Try to fight for a few days of warm days after sowing. The irrigation should not be too large before sowing, so as to soak the soil layer of 10 cm to 12 cm. Seed sowing after water infiltration, 7 grams to 10 grams of seeds per square meter. About 30 to 40 grams of seeds are needed for each hectare planted. Earth cover 1 cm to 1.5 cm after sowing. The plastic film was detained and covered with grasshoppers at night. Seedling management during the seedling period to maintain 25 °C ~ 30 °C during the day, at night 16 °C ~ 20 °C, about 5 days to 7 days to emerge. After the seedlings have been unearthed, the temperature is appropriately lowered to prevent the seedlings from growing in length. Keep it at 25°C during the day and around 15°C at night. From the time of sowing till the seedlings, the cold bed nursery is 60 days to 80 days, and the hotbed nursery is about 30 days. Sub-fungus seedlings can be used in greenhouses or Yangshuo with good insulation properties. If conditions permit, they can be used to set a minimum of 10 cm x 10 cm. 5 days to 7 days before planting, ventilation and cooling should be strengthened. During the day, maintain 20°C to 25°C and 15°C at night to exercise the anti-low temperature capability of the seedlings and improve the adaptability and survival rate after planting.
The suitable colonization period for early planting in planting spring is to be planted only when the ground temperature of the facility is 10 cm and the ground temperature is stable above 12 °C. 15 days to 20 days before planting, the protection facilities should be covered with plastic film and covered with grasshoppers at night to increase the temperature. At the time of planting, select the warm and sunny weather in the morning. Be sure to bring bandits to raise the roots to reduce the damage. The density of planting plants was 40 cm x 50 cm. The planting depth is slightly deeper than the original seedbed depth. Immediately after planting, water and plant seedlings. Immediately after planting, plastic film shall be detained and covered with grasshoppers at night to increase the temperature in the facility.
Management of seedlings in field management: All insulation measures should be taken to increase the temperature within the protection facilities. By cleaning the film, the light is improved, and the temperature of the grass seed is kept in a timely manner. The temperature is maintained at 25° C. to 30° C. during the day and 15° C. to 20° C. at night, so as to promote mild seedlings. After easing the seedlings, the temperature should be appropriately reduced, and the temperature should be kept above 25°C during the day and above 15°C during the night. After the planting water is slightly dry, sunny and warm weather should be selected for cultivating loose soil. Management of the fruiting period: After the eggplant is rejuvenated, cover and ventilation are used to keep the air temperature within the protected area within a proper temperature range, 25°C to 30°C during the day and 15°C to 18°C ​​during the night. Insulation opaque cover should be covered as soon as possible to cover the cover, to extend the time to see light. On sunny days, the plastic film can be fully opened and the plants can receive natural light for 5 hours to 6 hours. Outcome management: In the result period, lighting management should be strengthened to maximize the lighting time. During the day when the outside temperature is higher than 20°C, the plastic film can be peeled off to allow the plants to receive natural light. When the outside temperature is stable at 15°C or more at night, all coverings may be removed.
The proper harvesting period of harvested eggplant is before the “lingo eyes†are closed, ie, where the sepals are connected to the fruit. When the white parts of the peel are few, it indicates that the fruit grows slowly and is transferred to the developmental stage. Harvest time is appropriate in the morning or evening. Strong at noon, eggplant skin color is dark, high temperature is easy to wilt, not resistant to storage, it should not be harvested
