According to the natural law of plant growth and the principle of plant photosynthesis, plant growth lamp uses sunlight instead of sunlight to provide light source for plant growth and development. In other words, the spectrum that plants can absorb is a special spectrum technology, not all the light can supplement the light, so fluorescent lamps can not supplement the light of plants.
Light is closely related to crop growth. The maximum capture of light energy and the full play of photosynthesis potential of plants will directly affect the benefits of agricultural production. In recent years, due to the market demand, greenhouse is widely used in the production of anti season flowers, fruits, vegetables and so on. Due to the short time of sunshine in winter and spring, the growth of crops is slow and the yield is low, so it is urgent to supplement the sunshine. Most of northern China is located in East Asia, with temperate monsoon climate. In winter and spring, influenced by the cold air of Siberia, sometimes rain and snow are formed due to the convergence of cold and warm air currents. 1-3 days of low temperature and less sunshine, 7-8 days of cloudy and less sunshine. According to the statistics of Beijing in the past 50 years, the probability of such long-term negative weather is about 20%, 40% in the past 10 years and more than 60% in the past three years.
Affect the time of flowering and fruiting. Melon fruits and melon vegetables have certain requirements for light time and intensity. For example, when the light time of watermelon is less than 11 hours, all young fruits fall off. Vegetables with moderate light intensity, such as peas, beans, celery, radish, onion, etc. Low light vegetables, such as lettuce, spinach, chrysanthemum and ginger, need low light intensity. Solanaceae Vegetables are produced in Beijing greenhouse. Even in sunny days, the light intensity can not reach the light saturation point due to the shelter of the plastic curtain, but it can reach the light compensation point (which is also the reason why the taste of Eggplant and fruit vegetables produced in the solar greenhouse is weak). In cloudy weather, the light intensity is not enough, the light time is short, and the compensation point is not reached. As a result, photosynthetic efficiency decreased dramatically, dry matter
The accumulation of quality decreased rapidly and the disease increased rapidly.
The main way that plants can absorb is red and blue light. The laser plant growth lamp that our factory grows is to use the spectral technology needed by laser to synthesize the photosynthesis of plants and directly supplement the most needed lighting technology for plants. So a lamp can replace the effect of traditional 50 lamps. At present, the laser light supplement lamp has obtained the national patent
