[Explanation] At present, most greenhouses in China are "Dutch Venlo" multi-span greenhouses.
And in Shouguang, Shandong, the "Vegetable Capital of China" where the winter-heated greenhouses are popular, a new type of smart glass greenhouse independently developed and designed in China is put into use.
The greenhouse takes "sinking, large slope, external insulation" as innovative elements, applies more than 120 patented technologies, combines the thermal insulation and heat storage of Chinese solar greenhouses and the large space advantages of Dutch Venlo-type multi-span greenhouses, effectively solving The Dutch model greenhouses have high energy consumption and high operating costs.
[Explanation] The reporter went to Shouguang, Shandong Province on October 15 to see that this new type of smart glass greenhouse is 312 meters long from east to west and 256 meters wide from north to south. It adopts a 12-meter long-span planting surface and a suspended cultivation system, and the green tomato branches follow. The sling rope grows upwards, blooming tender yellow flowers.
It is understood that compared with the solar greenhouse, the greenhouse land utilization rate has increased by more than double.

China Shouguang Smart Glass Greenhouse is a greenhouse designed for China's climatic environment based on a climate characteristic of northern China.
From the structural point of view, we designed a large slope, external insulation, and positive pressure ventilation system.
On the intelligent equipment, we are equipped with positive pressure ventilation, including intelligent equipment such as robot system, carbon dioxide, and ozone spraying, water and fertilizer integration.
[Explanation] Lin Sen said that the main problem facing China's greenhouses is that the summer temperature is too high for production.
The "China Shouguang" smart glass greenhouse integrates the world's first time-sharing shut-off intelligent external insulation, solar greenhouse waste heat recovery, greenhouse air heat pump heating and other technologies, which can be continuously produced throughout the year, and the comprehensive energy consumption is lower than the Dutch model. More than half of the energy consumption.

The positive pressure environmental control system has the functions of heating and cooling, humidification and dehumidification, and air filtration, as well as carbon dioxide replenishment and ozone disinfection functions. It controls air quality from the source. The positive pressure ventilation system achieves the greenhouse environment control effect with optimal energy consumption. , It solves the problem of poor cooling effect in summer and difficult heat preservation in winter.
[Explanation] The reporter saw at the scene that only a few operators in the entire greenhouse were controlling the computers to help the tomato vines climb up, while the robots were busy shuttled in the shed.

(Set in the shed) Air source heat pump temperature adjustment system, positive pressure ventilation system, water and fertilizer integration system, robot operation system, plant factory, etc.
For this intelligent equipment, we have developed a set of managed greenhouse intelligent management and control cloud service system. Through this cloud service system, we realize cloud management and control of all equipment in the greenhouse.
We have designed 20 robots for a greenhouse to achieve less human operations in the links of pollination, transportation, spraying, inspection and sorting.
