The technique of controlling the growth of eggplant

The growth of eggplant is very exuberant, and the root system is relatively well developed. many growers are worried that eggplant will grow vigorously, resulting in too long jointing time and too large leaves, which will affect the late flowering and fruiting. Eggplant growth is also a common phenomenon in the planting process, so how to control eggplant growth? Let's get to know it.

1. Temperature control

During the fruit period, the suitable temperature for eggplant growth is 25-28 degrees during the day and 15-18 degrees at night. For overgrown plants, the temperature should be properly controlled, so it is best to be ventilated and ventilated when it is sunny during the day, and the greenhouse temperature should not be lower than 28 degrees. Controlling the night temperature is also the key point to restrain the vigorous growth of eggplant, especially the temperature in the second half of the night. Generally, the temperature in the first half of the night should be controlled at about 18-20 degrees in order to facilitate the transport of photosynthate in leaves, but the temperature in the latter part of the night must be low to inhibit plant respiration, and the temperature should be about 13 ℃ when uncovering the grass.

2. Moisture control

The emergence of warm water, avoid flood irrigation, should be watered every other line, only a fixed plant row can be, generally a half-ditch water can be irrigated at a time, eggplant plant control should not be excessive water control, if excessive control will appear some drawbacks. First, it causes poor flower bud differentiation and forms a short style, resulting in an increase in the number of malformed fruits; second, it results in poor plant growth, strong growth, large yellow leaves, and easy premature senescence; third, in the prosperous period of plant growth, there is a great demand for fertilizer and water, if long-term water supply and sowing, the root system absorbs water and nutrition is insufficient, resulting in slow fruit growth, easy to form stiff fruit, and low yield.

3. The growing plants should leave more fruit.

The vigorous plants should leave as much fruit as possible to adjust the balance of vegetative growth and reproductive growth, and the door eggplant can not be removed early, but should be removed after the eggplant grows to the size of an egg and three layers of eggplant flowers.

4. Chemical control

There are many plant growth regulators to control plant growth, such as dwarftin, paclobutrazol, paclobutrazol and so on, but in use, because the concentration of dwarftin and paclobutrazol is difficult to grasp, once the concentration is too high, the yield will be very low. Therefore, it is recommended to use booster or a higher concentration of 2.85% nitro-naphthalene acid water agent to adjust, the general concentration of bodybuilder is 750x liquid, and the concentration of 2.85% nitronaphthalene acid water agent is 3000 times liquid.
