Description

technical field [0001] The invention relates to the technical field of plant growth equipment, in particular to a laser radiation source plant growth device. Background technique [0002] Light environment is one of the important physical environmental factors indispensable to plant growth and development. Light regulates the growth and development of plants by affecting photosynthesis, photomorphogenesis, and photoperiod. Due to different climate zones or seasonal changes, sometimes crops inevitably grow in low-light adversity. In recent years, most parts of North my country, including Beijing, have experienced long-term smog in winter. The resulting low temperature and lack of sunlight have brought serious growth obstacles and even devastating blows to the planting of overwintering stubble facility vegetables. Supplementing light with artificial light sources is a necessary measure to help facility vegetables grow quickly and safely. In addition, with the continuous incre...

Problems solved by technology

In recent years, a large number of photovoltaic greenhouses have also caused great shading effects on crops

The long-term weak light growth of crops will lead to problems such as unhealthy plant nutrition, severe flower and fruit drop, slow fruit development, reduced sugar content, reduced yield, and poor quality.

When the crop is below the light compensation point, the net photosynthetic product accumulation in the leaf is very little or even zero, which seriously hinders the normal growth of the crop to the demand for photosynthetic product
