First, field finishing. Eggplant is not very tolerant to high temperatures and heavy rains. After the summer planting season, the region typically enters a period of high temperature and heavy rainfall. Therefore, it's important to select sandy loam soil with good drainage and higher elevation. Clay loam soils tend to retain water and can lead to plant death during rainy seasons. It's essential to dig proper irrigation and drainage ditches, level the land to prevent waterlogging, and avoid root rot. In addition, using raised beds is recommended. The bed height should be between 20-45 cm, the width around 100-120 cm, and the spacing between beds about 20-30 cm. Eggplant is a deep-rooted, high-fertility, and moisture-tolerant crop. It’s advisable to apply a deep layer of base fertilizer. For every acre, you can use 5,000 kg of well-rotted organic manure, 40 kg of monoammonium phosphate, and 30 kg of potassium sulfate, evenly spread and incorporated into the soil. If organic material is abundant, you can increase the organic manure to over 10,000 kg per acre, along with 50 kg of calcium phosphate. If the soil already has sufficient organic matter, chemical fertilizers alone may be used—such as 100 kg of urea granules, 50 kg of superphosphate, and 50 kg of potassium sulfate. Second, planting. The best time for eggplant transplantation is generally from early June to early July after the previous harvest. However, it's better to transplant as early as possible to allow enough time before the peak of summer. During the first 1-2 days after transplanting, it's important to observe the seedlings at noon. The daytime temperature should be maintained around 30°C, and nighttime around 18-20°C in the initial stage. Later, when the plants are more established, daytime temperatures can go up to 28-30°C, while nighttime stays around 15-18°C. Eggplants grown during the summer have a long growth cycle. Pruning should be avoided initially, allowing natural growth. After the first harvest, old leaves should be removed. Once the fruit begins to form, the top two outer branches can be cut to create a double stem structure. When the four-door bucket eggplant starts to develop, the central shoot should be removed. Typically, 5-7 fruits per plant are left. As the plant develops, the planting density should be around 1800-2000 plants per mu. Planting depth is important, and after planting, plenty of water should be given to help the seedlings settle in. When the first tomato-like fruit appears, regular weeding should be done to prevent pests like grasshoppers. During the summer rainy season, watering and fertilization should be increased. Watering should be done once within 7 days after planting, and then controlled until the next stage. When the fruit reaches 3-4 cm in size, start top-dressing and irrigation under the plastic film. Eggplant requires consistent moisture. If water is scarce, furrow irrigation can be used. When watering, dissolve fertilizers such as ammonium nitrate (0.3%), monoammonium phosphate (0.15%), and potassium sulfate (0.2%) in the water. During furrow irrigation, fill the ditch with water and spread the fertilizers evenly. Per mu, this would be approximately 15-30 kg of ammonium nitrate, 10 kg of monoammonium phosphate, and 10 kg of potassium sulfate. If there is no water shortage, you can dig small holes between every four eggplants and place well-rotted manure in them. After top-dressing, ensure good ventilation to prevent diseases caused by excessive fertilizer. After the first top-dressing, repeat it every 15 days. Each application should include 10-15 kg of urea, 10 kg of diammonium phosphate, and 5 kg of potassium sulfate per mu. Timely watering will promote plant and fruit development, prevent premature aging, extend the harvest period, and boost late-season yields and economic returns. During the flowering stage, you can spray 20-30 mg/kg ribarb on the flower stalks and calyxes. Once the fruit has developed sufficiently, remove the treated corollas to improve fruit set rates. In summer and autumn, close attention must be paid to weeding, pest control, and field maintenance. To manage weeds, you can spray 48% trifluralin at a rate of 100-150 grams per mu after planting. This method effectively controls weeds while reducing labor requirements.
