Not too many times Many vegetable farmers believe that the more eggplants harvested in more than one time, the higher the benefits. However, the result was too many times and the benefits were reduced. Because eggplant has a certain growth law, only by following this rule can there be high benefits. The solution is to use a large cultivar for wintering cultivation, one planting for one year, and using the spring and autumn cultivars for one year. Each year in the summer to stay for some time to deep turn over rain and salt, sunburn bactericidal, shed worms, mature soil, so eggplant grows well, and high efficiency. Fertilizer amount should not be too large Excessive fertilization will result in high concentrations of soil solution, reverse osmosis in the root system will die, and production will naturally decline. In particular, greenhouses have high temperatures and high humidity. Organic fertilizers are rapidly degraded. The availability of phosphorus is 2 to 3 times higher than that of exposed land. The volatilization of ammonia is large, and over-fertilization can easily cause fertilizer damage. Solution: Plant the greenhouse of Solanaceae for more than 3 years. The application amount of organic fertilizer is controlled within 5,000 kilograms and the fertilizer is buried after it is applied. High-salt concentration plots should pay attention to the application of cow dung, humic acid fertilizer and EM bacterial fertilizer to increase the ratio of soil carbon to nitrogen, loose soil permeability, salt and fertilizer reduction. At the same time, it supplements trace elements such as boron, zinc, and magnesium to balance soil nutrients. The temperature should not be too high The eggplant's upper temperature limit is 32°C. If the temperature is too high, the respiration is enhanced, the physiological activity is disturbed, the fruit set is restrained, the plants are lengthy, the vegetative growth and reproductive growth are unbalanced, and the yield is decreased. The solution is strictly controlled according to the required temperature of each growth stage of the eggplant and the optimum temperature for the growth period of each organ. In case of high temperature, the temperature is lowered in time to prevent the high temperature long branches from being long fruit.
