LED lighting plants increase 30%
See the cherry tomatoes in the shed like a string of small lanterns, covered with branches. In Shouguang City, Shandong Province, Tian Liu Town, Village Tangjiazhuang a greenhouse, LED fill lighting is in the top of the cucumber plant, 40 cm above the exudes a soft purple light. In this real area of more than 2 acres of greenhouses, in addition to fill lighting, there are supporting physical thermostat facilities.
The people of Tian Liu Town, Shouguang City Tangjiazhuang told reporters that he is the kind of "newcomer" last year just started his own greenhouse, no experience before. Wehther good harvest is the questions that beat his heart every day. Since July last year, using the two technologies of light bulbs and physical thermostat facilities of physio-agribusiness, the fruits and vegetables have thicker, larger and more uniform fruits, and have significantly improved their color and taste. The same management, picked up in December last year, has seen a 14% increase in output, while the output of the other capsicum has increased by more than 30%.
It is understood that this new "LED plant growth fill light" can be manually controlled or automatically turn on the light time needed to make up for the crops in the cloudy and night without sunlight irradiation of the neutral, to achieve the extension of the light time, increase production efficiency purpose. Greenhouse temperature control facilities, through the "main pipe + branch pipe + breathable hole" in the form of a similar drip irrigation, the effective use of shed heat to improve ground temperature and reduce the greenhouse heat loss. The effect is particularly evident in winter, the device opened 2 hours, can increase the temperature to 1.7 degrees Celsius. One-time investment in a greenhouse 6000 RMB, can be used for nearly 10 years.
LED fill light, which can be in accordance with the needs of plant growth by a certain percentage of the modulation spectrum. Second, cold light source can be close to plant irradiation, after continuous practice to determine the distance of 30 to 50 cm, while ensuring light intensity and light area. Fourth, energy saving, environmental protection, long life, small size, light weight. Fifth, the device is diverse (light board, light with lights, lights Tube and light bulb), suitable for all kinds of facilities agriculture project ". Currently the company in Shouguang have many vegetable bases for cooperation test, and achieved remarkable results.
