The Beijing HortiPolairs Agricultural Science and Technology Park has adopted world-class facilities and technologies to create a "cross-border" trial of efficient, green, and smart agriculture. The park covers a total area of about 18 hectares, including a tomato planting area of 2.2 hectares, a hydroponic lettuce area, and a nursery area.
One of the biggest benefits of this Park is that the water consumption per unit area is less than 1/10 of that of traditional agriculture, but the output is 10 times that of traditional agriculture.
One of the reasons for this high output is the movable gutters: "We use fully automatic movable cultivation gutters. As the lettuce grows, the cultivation gutters will move forward, leaving a suitable space for the lettuce growth," said Xu Dan, general manager of HortiPolaris Agriculture.
The cultivation gutter is made of an aluminum alloy, which ensures the uninterrupted production of lettuce throughout the year. A nutrient solution is sprayed every 5 minutes and flows through the roots of the lettuce down a slope. The excess solution can be recycled, which saves water and ensures that the roots have sufficient oxygen. The application of this new technology has increased the production of lettuce. Now, there are just 6-7 weeks between sowing and harvesting. In a small area of 2000 square meters, a total of 700,000 lettuce plants can be produced a year, which is more than 10 times that of traditional-grown lettuce.
In the nursery area, the roof is made of diffuse glass to make the crops evenly exposed to light. Here, 8 lettuce varieties are part of a cultivation experiment to learn more about the growth of lettuce.
The application of tidal nursery systems, artificial lights, curtains, and other technologies creates the best environment for the nursery so that the nursery area can cultivate 6-7 million seedlings a year.
Tomatoes are also grown in the Park. In the tomato greenhouse, bees fly in and out of the beehive to pollinate the tomato plants.
Precautions against harmful insects are also taken: a piece of yellow tape next to the plants and netting just below the roof prevent them from entering the greenhouse and harming the plants, which also means that pesticides are not necessary.
Xu Dan explained that the greenhouse has realized fully automatic and intelligent management. In addition to transplanting seedlings, twisting stems, trimming leaves, flowering plants, and harvesting, there is almost no need for operators. The "intelligent " systems operate on their own, creating a stable environment for crop growth. As long as there is the Internet, the greenhouse can be remotely managed no matter where you are.
This industrial park also recycles CO2. Furthermore, the greenhouse is equipped with shading and heat-insulating double-layer curtains, making it possible to prevent the light from causing any disturbance.
