Technology of controlling vegetable growth in greenhouse

Greenhouse vegetables are invented to change the seasonal growth restrictions of vegetables. It is clear to control the growth process of vegetables, make them grow better, increase production, and try to grow as long as possible before the stage they want to sell. So in what ways can we start to control prosperity? Let's take a look at this technology.

1. Temperature control

Temperature is the key to the greenhouse, the growth rate of plants will be inconsistent because of the temperature. When controlling prosperity, we must fit the growth temperature of vegetables at all stages. For example, in the flowering stage, the temperature of vegetables is generally not high, because the pollen can not bear it. At this time, the temperature needs to be lowered appropriately in order to pollinate the flowers better. After the result, the fruit is more active under the high temperature, at this stage, the temperature should be raised slowly, so that the fruit can grow well, which is controlled by the temperature.

2. Lighting control

The growth of all things depends on the sun, the growth rate of branches and leaves of vegetables will generally vary with the amount of light, less sunlight, vegetables may appear first yellow leaves, branches and so on, because their light is less, the photosynthesis is not obvious, the whole vegetable is not active. Vegetables have the highest demand for light during the growing period, when there is enough light, vegetables can easily expand, and this is the best time to control growth through light.

3. Water control

Water is the life source of vegetables, so how to use water to control prosperity, I believe everyone is quite confused, in fact, this is not very difficult. For vegetables, the absorption of water starts from the root system, if there is less water, it is generally absorbed by the root system, as long as a small part of it will supply stems and leaves, so that the growth of vegetables is slow. If there is more water, the whole vegetable can absorb water, so that it can grow vigorously. However, water control should be adjusted according to the growth of vegetables at all times, and the requirement is relatively high.

4. Artificial control

Prosperity control can also be controlled artificially, which is more widespread. Some vegetables will have some abnormalities during their growth, resulting in their own slow growth. The common ones are interlaced, twisted branches and not facing the sun, which leads to its poor growth, which needs to be corrected so that it can return to a state of prosperity. Others are growing too well, and they don't have much to gain. This needs to be curbed.

Controlling prosperity not only means making vegetables grow well, it mainly helps to increase production. Control prosperous also do not let vegetables grow wildly, reasonable adjustment can make their own income higher.
