Summer sown eggplant is generally raised in the open season in mid-April, and crops after the harvest (wheat, rapeseed, ground beans, garlic, etc.) are planted after the middle and mid-June, and are available from the end of July to October. The climate characteristics of summer sow eggplant cultivation are mainly as follows: The result period is at a high temperature and rainy season. This season is not conducive to the growth, flowering, fruit setting of eggplant, and the vegetable farmer must grasp the relevant management work.
First, colonization
Before the planting of eggplant seedlings, 300 times the colubrid ammonia solution was sprayed on the seedbed to control the Verticillium wilt disease; 70% thiophanate-methyl was sprayed with 1000 to 1200 times concentration to prevent and control fungal diseases; Spray 50% was used to spray the wettable powder 2000 ~ 3000 times liquid control aphids.
The planting time of eggplant seedlings is generally in mid-June, and the colonization is too early. The flowering period is a high-temperature rainy season, and it is easy to cause a large number of falling flowers and fruit drop, which will affect the output. If the planting is too late, the plants will not enter the high-temperature and high-humidity season without easing seedlings, which will easily lead to less seedling roots, weak seedlings, and severe disease, failing to safely fail over summer. Therefore, timely and rational planting should be carried out so that the peak of the eggplant plant flowering results after the summer.
To bring bandits to plant seedlings to prevent tomato seedlings from wilting, it is best to choose cloudy days or after 4:00 pm. If it is sunny and planting, pay attention to the watering with the seedlings, and soak the planting water. Summer sowing eggplant grows rapidly, easily causing plant closure, so the planting density should be small, generally 1500-1800 strains will be planted in Mu, and plant spacing will be 40-50 cm.
Second, the management after planting
Drenched planting water, 2 to 3 days after the earth, lyrical, seedlings can be poured 1 time Huanmiao water, timely cultivator weeding 2 or 3 times to promote its hair root, hair tree. In the summer, weeds grow rapidly. If weeding is not done in time, the weeds will compete for nutrients with the eggplant seedlings, which will lead to weak eggplant seedlings and affect yield. Eggplant seedlings are properly ploughed into high ridges before ridge ridges, and the accumulated water is promptly removed after heavy rainfall. When the soil moisture is high, wheat stalks can be placed in the ridges to reduce the humidity, reduce the area of ​​water and water evaporation, and also suppress weeds and prevent rotting. . Spray insecticides and fungicides regularly every 10 to 15 days to prevent the occurrence of pests and diseases, and pay attention to the alternation of pesticides.
When 30% to 50% of the plant's door eggplant egg size, start watering. Urea urea 7 ~ 10 kg, potassium sulfate 10 kg. Later, depending on the weather, the water is poured every 5 to 6 days. Every time the water is chased once, the amount of urea is 10 to 15 kg per mu. Pay attention to the pruning and wipe out the buds on the lower part of the eggplant as soon as possible to avoid consumption of nutrients. For the headless locust caused by pest damage, mechanical damage, and calcium deficiency, all the original leaves should be taken off under the premise of raising the root system. A new growth point can be educated within 7 to 10 days, and then poured 700 times after picking the leaves. Zijin zinc sulfate promotes new shoots. Summer sowing eggplant grows quickly, luxuriant foliage, after ridge closure, pull a wire (rope or bamboo raft) on each side of the eggplant plant, and fix it every 8 to 10 meters plus wooden stakes. Sometimes the female flower is wilted when it is not yet open. This is because of excessive florescence caused by excessive concentration of soil solution. If the pH value of the soil exceeds 8.2, the alkali should be poured with water, and the wheat straw should be kept moist on the ground to reduce the amount of evaporation, control the alkali return, or not apply fertilizers with less salt.
The timely harvesting of the door eggplant can be picked as soon as possible when it can be listed as a product. Malformed fruit does not grow well and should be removed early. Young fruit more than 6 to 7 should be early fruit thinning. After harvesting the door, timely removal of the old leaves of the lower part of the door, air and light. After the eggplant is harvested, it enters the expanse of the four-door hopper, and it is during the vigorous growth period in autumn. The supply of water and fertilizer should be strengthened. Apply 10 kg of urea or 20 kg of ammonium sulfate per mu and fertilize once every 10 days to promote plant and fruit growth. Development, prevention of premature aging, prolonged harvesting period, increase of late production and economic benefits. After entering the hot and rainy season, the high-temperature and high-humidity climate is conducive to the occurrence of various diseases and insect pests. The focus is on the prevention of eggplant ooemorrhagia, and it is necessary to insist on regular spraying.
