How to Control Excessive Growth in Greenhouse Vegetables? Latest Technical Methods Tutorial

Greenhouse vegetables were invented specifically to change the seasonal growth limitations that vegetables face. Growth control, plainly put, means controlling the growth process of vegetables so they grow better, increase yield, and grow as much as possible before the stage at which you want to sell them. So from which aspects can growth control begin? Let's take a look at this technique together below.

1. Temperature control

Temperature is the key to a greenhouse. Plants grow at inconsistent speeds depending on high or low temperatures. When controlling growth, you must match the growth temperature of vegetables at each stage. For example, during the flowering stage, vegetables generally do not need high temperatures, because pollen cannot withstand them. At this time, in order for the flowers to pollinate better, the temperature needs to be lowered appropriately. After fruiting, the fruit is more active under high temperatures, so at this stage the temperature should be gradually raised, and only then will the fruit grow well. This is controlling growth through temperature.

2. Light control

All things grow relying on the sun. The growth speed of vegetable branches and leaves generally varies with the amount of light. With less sunlight, vegetables may first show yellow leaves, wilted branches and so on, because with less light their photosynthesis is not obvious and the vegetables as a whole are not active. Vegetables have the highest demand for light during the growth period. At this time, if there is enough light, the vegetables can easily expand and spread out. This is the best period for controlling growth through light.

3. Water control

Water is the source of life for vegetables. So how to use water to control growth is something everyone is probably rather confused about, but actually it is not very difficult. For vegetables, water absorption starts from the root system. If there is a little less water, it is generally absorbed by the root system, and only a small part will be supplied to the stems and leaves, so the vegetables grow slowly. If there is too much water, then the whole vegetable can absorb water, and thus it can grow vigorously. However, water control must be adjusted at all times according to the growth condition of the vegetables, and the requirements are relatively higher.

4. Artificial control

Growth control can also be done artificially, and this is relatively broad. Some vegetables show abnormalities during growth, causing them to grow more slowly. Common ones include crossing each other, twisted branches, and not facing the sun, which causes poor growth. These need to be corrected by you to restore them to a vigorous growth state. There are also some that grow too vigorously, in which case not much can be harvested, and these need to be suppressed.

Growth control is not only about making vegetables grow well; its main purpose is still to help increase yield. Growth control should not blindly make vegetables grow wildly either. Only reasonable adjustment can bring you higher returns.
