How to make up the light of vegetables in greenhouse

The disease of crop growth is required by temperature and light, but the problem of lack of light often occurs when growing vegetables in greenhouse in winter, which greatly affects the quality of vegetables. So how to replenish light for greenhouse vegetables in winter? Come and have a look with the editor.

1. Mechanical rolling curtain

The mechanical shutter can be used in winter, which can not save a lot of manpower, reduce the labor force, and the speed of uncovering the grass curtain manually is faster, can save a lot of practice, and can more effectively prolong the lighting time of vegetables in the shed.

2. Use the light conversion film

In the greenhouse construction, the plastic film can use light conversion film to buckle the shed, which can increase the light intensity in the greenhouse, which is very beneficial to the growth of vegetables in the greenhouse.

3. Do a good job of cleaning greenhouse film.

The greenhouse film of vegetables in the greenhouse is mostly transparent, which allows vegetables to receive more light, but if there is dust or dirt on the greenhouse film, it will reduce the light transmittance of the greenhouse film. Therefore, it is necessary to often clean the dust and dirt on the greenhouse film, and there are dozens of clean snow when it snows, keep the film clean, and keep the light transmittance of the greenhouse film as high as possible, so as to increase the light duration of vegetables.

4. the ground is covered with plastic film

The vegetables in the greenhouse can be covered with plastic film. This can not only increase the ground temperature and reduce the humidity in the greenhouse, but also reflect light, further increase the light intensity at the base of vegetables, and make up for the lack of light in the greenhouse.

5. Hang a reflective screen

But the ground cover is somewhat similar, hanging a reflective curtain on the wall of the shed can also significantly enhance the light intensity of vegetables near the wall, and the vegetable yield in this area has been significantly improved.

6. Artificial supplementary light

In continuous cloudy days, rain and snow weather, when the natural light is obviously insufficient, artificial light is needed. If possible, you can turn on the electric light or light the biogas lamp to help vegetables tide over the difficulties and prevent vegetables from dying due to lack of light for a long time.

7. Pruning and leafing

Timely pruning and leafing in the process of vegetable growth and timely removal of dead branches and old leaves can not only save nutrient consumption, but also improve the lighting conditions of vegetables in the greenhouse and increase vegetable yield.
