How to grow vegetables in modern automated smart glass greenhouses

In traditional agriculture, at least 20 people are required to manage every 10,000 square meter greenhouse. In the automated smart glass greenhouse, this number has been reduced to half. In the near future, it will be based on the standard of 5 people per 10,000 square meters, but the yield is higher than that of traditional agricultural planting. 10 times. Under the operation of the Internet of Things control system, the entire glass greenhouse's plant growth elements such as water and fertilizer, temperature, illumination, and climate have all realized intelligent control. The indoor temperature during the day is controlled at about 25 degrees, and the temperature at night is controlled at about 18 degrees to ensure that the crops are in a comfortable growth environment all year round to ensure the growth of the crops. When there are alarm messages such as high humidity in the greenhouse, too strong or too weak light, the operator only needs to operate in front of the computer, and the equipment will automatically operate according to the set program, realizing unmanned management and automatic operation. In the Youyou Sino-Dutch Agricultural Innovation Park, only some auxiliary tasks such as picking, vines, and old leaves are still manually completed. With the upgrading of technology, unmanned management is gradually realized.

The automated smart glass greenhouse currently mainly grows four types of vegetables: tomato, cucumber, pepper and lettuce. Every 10,000 square meter greenhouse provides more than 30 tons of fresh vegetables every year. Before entering the greenhouse, it is necessary to wear isolation clothing and headgear, and to enter the greenhouse after repeated disinfection. All the soil for plant growth is replaced by the substrate rock wool sliver. The substrate itself has no nutrition, but through the water-fertilizer integrated circulation irrigation system, it is equipped with different nutrient solutions to deliver the nutrients needed by each plant to ensure the normal growth of each plant and fruit.

The top ventilation and side ventilation of the greenhouse are equipped with anti-insect nets to prevent outside mosquitoes from entering. The inside of the greenhouse is above the three-dimensional planting trough, and strips of yellow sticky boards are used to stick flying insects. A large number of small insects called "predator mites" are placed in the greenhouse, and they are used to prey on pests. A beehive is also placed in the greenhouse to achieve pollination by bees by simulating the natural growth environment of plants.

As a high-standard modern glass greenhouse, the waste gas generated by the heating of the greenhouse is processed by a special device and sent to the greenhouse as gas fertilizer, thereby reducing carbon dioxide emissions and achieving recycling. Next to the greenhouse, there is a huge rain pond of 100,000 cubic meters. The filtered rainwater becomes irrigation water for plants, which will not increase the water pressure of the area. The dripper for irrigating plants is a pressure-compensated dripper, which mainly controls the water output and water stop by the pressure in the pipe. Through computer program control, large-area irrigation can be completely averaged. Once the water is enough, the irrigation will be stopped, and there will be no waste. Use the least amount of water to irrigate as many plants as possible. The surplus waste liquid will be reused after being recycled. At present, the country vigorously develops modern agriculture and promotes the development of high-quality and high-efficiency agriculture by introducing modern agricultural planting technologies. So that traditional agriculture gradually develops into modern agriculture.
