A 90,000-square-meter greenhouse becomes the most advanced greenhouse in China

Out-of-season vegetable cultivation has become the main channel for many farmers to gain income. Even though the development of greenhouses in China is relatively late, smart greenhouses have entered people's vision after years of development. A greenhouse in Shandong covering an area of 90,000 square meters, including 80,000 square meters for planting and 10,000 square meters for operation, with an investment of 210 million yuan, claimes to be the most advanced greenhouse in China.

A greenhouse with an investment of hundreds of millions bears incredible tomatoes for sure. The length of a tomato vine is more than 20 meters after a complete growing season. A technical administrator of the greenhouse said that tomatoes can grow indefinitely out of their characteristics, which is also related to the selected variety. Claiming to be the most advanced greenhouse, this unit is equipped with state-of-art facilities related to water, fertilizer, gas, and temperature control. To let tomatoes grow infinitely, the water system and the climate control system are crucial. The climate control system of the greenhouse comes from the Netherlands, the engine system comes from Locke in Germany, the irrigation system comes from Netafim in Israel, and the IoT system comes from Svensson in Sweden.

At present, the yield of tomatoes in the greenhouse in China is about 10-15 kg per square meter, while the yield in the Netherlands can reach 70-80 kg per square meter. In order to catch up with the technology used overseas, the greenhouse in Shandong was initially designed to achieve the maximum intake of natural light and reduce long-wave outward radiation by completely using large pieces of glass (2.0 m x 1.7 m).

The roof of the greenhouse is equipped with a cleaning mechanical device, which can effectively increase the intake of natural light by 10%. Within the greenhouse, laser lighting technology is applied, which is more power-efficient than LED. The brightness has reached more than twice that of LED.

While the common tomatoes are sold by kilograms, the tomatoes produced in this greenhouse are sold by bunches. The price is about 15.8 yuan per box, with a bunch in the box. The tomatoes produced have no stock, and they are sent directly to first-tier cities such as Beijing, Shanghai, and Guangzhou after being picked and packaged.
