Three things to avoid when growing eggplant
Avoid too many cropping cycles. Many vegetable growers believe that the more cropping cycles, the more eggplant they harvest and the higher the profit is bound to be. But in the end, too many cropping cycles actually lowers the profit. This is because eggplant has a certain growth pattern, and only by following that pattern can you achieve high profits.

Avoid too many cropping cycles
Many vegetable growers believe that the more cropping cycles, the more eggplant they harvest and the higher the profit is bound to be. But in the end, too many cropping cycles actually lowers the profit. This is because eggplant has a certain growth pattern, and only by following that pattern can you achieve high profits.
Solution: With overwintering single-crop cultivation, planting once a year is enough; with spring and autumn cropping, two crops a year is best. Each year in summer, leave a period of time for deep plowing and rain leaching to reduce salt, sun-drying the soil clods to sterilize, closing the greenhouse to kill pests, and mellowing the soil. This way the eggplant grows well and profits are high.
The amount of fertilizer should not be too large
Applying too much fertilizer causes the soil solution concentration to become too high, and the roots undergo reverse osmosis and die, so yields naturally decline. This is especially true in greenhouses, where the temperature is high and the humidity is high, organic fertilizer decomposes quickly, phosphorus availability is 2 to 3 times higher than in open fields, and ammonia volatilization is large, so excessive fertilization very easily causes fertilizer damage.
Solution: In greenhouses that have grown Solanaceae crops for more than 3 years, keep the organic fertilizer application rate within 5000 kg per mu, and bury chemical fertilizer after application. For plots with high salt concentration, focus on applying cow manure, humic acid fertilizer and EM microbial fertilizer to raise the soil carbon-to-nitrogen ratio, loosen the soil and let it breathe, and release salt and reduce fertilizer damage. At the same time, supplement trace elements such as boron, zinc and magnesium to balance soil nutrition.
The temperature should not be too high
The upper temperature limit for eggplant is 32°C. If the temperature is too high, respiration increases, physiological activity is disturbed, fruit set is inhibited, the plants grow leggy, vegetative growth and reproductive growth fall out of balance, and the yield actually declines.
Solution: Manage strictly according to the temperature required at each growth stage of eggplant and the suitable temperature requirements for each organ's growth period. When high temperatures occur, cool down promptly to prevent high temperatures from growing branches without growing fruit.
