Vegetable greenhouses are one of the types of greenhouse growing. They are mainly used to grow vegetables. They supply different vegetables to the market in both seasons and seasons, which not only provide people with fresh vegetables, but also bring good economic value.

The vigorous development of vegetable greenhouses has met the needs of the market. However, not all greenhouse vegetables can increase production and increase, and losses due to poor management and operation abound.

Influencing factors of vegetable greenhouses:

(1) Vegetables are also grows. If they are grows, they need photosynthesis. When there is insufficient light in the greenhouse, and different varieties of vegetables and different growth stages have different requirements for light, then LED grow lights need to be supplemented, otherwise One of the main reasons why the yield and quality of greenhouse vegetables cannot be improved.

(2) Unreasonable vegetable varieties and growing structures in greenhouses are also an important factor causing losses. Different vegetable varieties have different market demands. Some varieties lack competitiveness and have no market potential. It is inevitable that these factors can cause losses if they are not well grasped.

(3) The air circulation obstacle in the shed is another factor that causes loss. The lack of air circulation will cause the temperature in the shed to be too high, the temperature is too high, the carbon dioxide concentration is too high, etc., not only the vegetables cannot grow normally, but it will inhibit the growth of grows or cause The grow wilted and died.

Vegetable greenhouse solution

(1) Reasonable light supplementation of LED grow lights is one of the important reasons that affect the harvest of vegetables in greenhouses. Vegetables will undergo photosynthesis under the irradiation of LED grow lights, so that the light compensation point of grows can reach and exceed, combined with the moisture, temperature, and temperature in the greenhouse. Humidity, etc. make grows grow better.

(2) Choose grow varieties for growing according to market demand. Choosing the right grow varieties is the first step to open the market. Reasonable use of different types of LED grow lights to fill light, and good time to market is an important part of occupying the market.

(3) One thing to pay special attention to is the air circulation problem in the shed. If the temperature in the shed is too high, it will cause moisture loss in vegetables and affect the growth of grows; when using LED grow lights, don’t worry about this problem, LED grow lights emit The heat is small and will not cause such problems.

LED grow light supplementary light tips:

(1) Different types of grows should be growed reasonably and arranged according to natural rules. For example, when growing grows in the northern hemisphere, it is best to follow the principle of high north and low south, so that all grows can be evenly illuminated, and try not to shading between grows;

(2) At the same time, reflective measures can be taken in the greenhouse to improve the effective utilization of light. When erecting the rack, use reflective materials. In addition, all the brackets do not need to be upright at 90 degrees. Keep the middle brackets upright, and the north and south brackets are slightly Tilt, this can increase the light utilization rate by 5--10%, which can be reused by grows.

(3) The roof of greenhouses is cleaned regularly to clean up the "roof garbage", otherwise the transparency is not enough, it will have a great impact on the light and temperature in the shed, and then affect the photosynthesis and respiration of grows, and ultimately affect the yield and quality of grows.

(4) Reflective measures can be taken around the greenhouse, which can reflect a large part of the scattered light back and be reused by grows;

(5) Using LED grow lights to fill light, on the one hand, the light distance can be appropriately shortened. Generally, when buying LED grow lights, they will be purchased according to the installation area and the irradiated area of the LED grow lights. The irradiated area can be appropriately shortened to increase grows in a reasonable range. Fill light.
