Comprehensive measures should be taken to prevent the growth of round eggplant.

At present, because the greenhouse begins to close at night for heat preservation, the night temperature is often too high, so that the round eggplant in the greenhouse grows seriously. In order to prevent the round eggplant from flourishing without setting fruit, the reporter found that vegetable farmers generally adopt the method of water control. However, it is difficult to achieve the desired effect by relying solely on water control in production, and there are many disadvantages of excessive water control, such as poor flower bud differentiation, abnormal fruit and so on. The author believes that there are many factors leading to plant growth, so comprehensive measures should be taken to control plant growth instead of blindly excessive water control.

Temperature control tree. The suitable temperature for eggplant growth is 25-28 ℃ in daytime and 15-18 ℃ at night. If the plant is too prosperous, the temperature can be controlled relatively low. Ventilation in time when the weather is fine during the day, and the temperature of the shed should not be higher than 28 ℃. Reducing the night temperature is the key point to restrain the prosperous growth, especially in the latter part of the night. The temperature in the first half of the night can be controlled at 18-20 ℃, which is beneficial to the transport of photosynthate in leaves, and the suitable temperature in the second half of the night is 12-15 ℃.

Water control the tree. Although excessive water control is not good, but an appropriate amount of water control is one of the good ways to control trees. The emergence of prosperous and long shed, avoid flooding, should be watered every other line, only fixed planting line can be. To water a small amount of water, you can usually pour half a ditch water at a time. Paddle the hoe frequently after watering.

Control the tree by its fruit. Overgrown plants should keep eggplant and leave as much fruit as possible to regulate excessive vegetative growth. Door eggplant can not be removed early, should be the size of eggplant eggs, three eggplant flowers and then removed. If the plant is still growing vigorously at this time, the door eggplant can not be removed, and the door eggplant will be twisted clockwise, and the door eggplant will be removed when the eggplant expands rapidly.

The potion controls the tree. There are many plant growth regulators to control plant growth, such as dwarftin, paclobutrazol, paclobutrazol, etc., but because the concentration of dwarfin and paclobutrazol is difficult to master, it is suggested that vegetable farmers should use booster or higher concentration of Aidoushou to regulate. In general, the concentration of Zhuangzhu is 750x, and that of Aiduo is 2000 times.
