According to the needs, the new “plant growth fill light” can manually adjust or automatically turn on the illumination time to make up for the neutral sunlight of crops on cloudy and nighttime, and achieve the purpose of prolonging the illumination time, increasing production and increasing efficiency. The greenhouse temperature control facility uses the form of “main pipe + branch pipe + venting hole” similar to drip irrigation to effectively utilize the heat in the shed, increase the ground temperature, and reduce the heat loss in the shed. In winter, the effect is particularly obvious. When the device is turned on for 2 hours, the ground temperature can be increased by 1.7 degrees Celsius. A greenhouse can be used for 10,000 yuan at a time and can be used for nearly 10 years.

China's agriculture is divided into three stages. Originally it was traditional agriculture. It relied on heaven to eat, then upgraded to chemical agriculture, and increased income through chemical fertilizers and drugs. Now, with the improvement of quality requirements, it has begun to change to physical agriculture, using environmentally safe physics. Technology, in the vegetable production process to assist growth, pure natural, non-polluting, to create the best state of plant growth, so that farmers achieve increased harvest.

LED fill light, one can adjust the spectrum according to the plant growth demand according to a certain ratio, and the second is that the cold light source can be close to the plant illumination. After continuous practice, the distance is determined to be 30 to 50 cm, and the light intensity and the illumination area can be ensured at the same time. Third, it has strong controllability, can accurately regulate light intensity, light quality and photoperiod, and is suitable for workshop production. The fourth is energy saving, environmental protection, long life, small size and light weight. The fifth is the variety of devices (light panels, strips, tubes and bulbs), suitable for all types of facility agriculture projects.
