Recently, the reporter learned from the District Agricultural Investment Group that the city's first plant factory, Xutian Plant Factory, which began construction in November 2017, has been fully built and put into production in Tongnan District of Chongqing.
Totally enclosed sterile environment confers green genes to vegetables
Xutian Plant Factory is constructed by Shaanxi Xutian Company in cooperation with Chongqing Tongnan National Science and Technology Agricultural Park, covering an area of about 6600 square meters, a total investment of about 8 million yuan and a construction area of 1000 square meters, including cultivation room, nursery room, operating room, equipment room and observation corridor and other functional areas.
Walking into the plant factory in Xutian, the reporter was attracted by the vegetable in the cultivation room. The vegetable layers seemed to grow in midair, and the thick green color came through the colorless glass. "These cultivation rooms are fully enclosed, in order to ensure that the cultivation environment is aseptic and dust-free, staff must wear aseptic suits, masks, after the wind shower equipment, can enter." He Haiyan, a staff member who just came out of the cultivation room, told reporters that unlike the natural environment, vegetables grown here will not be affected by extreme weather such as storms and rains, let alone worry about the most direct insect pests, even if there are a small number of mosquitoes, can be killed by physical means.
Fully enclosed cultivation allows vegetables to live in a "safe haven", which not only effectively eliminates the use of pesticides, but also ensures the "green" nature of vegetables. "Through routine inspection, nutrient solution testing, timely detection of problems in the growing process, to ensure that our vegetables meet the safety and comfort standards." He Haiyan said that the vegetables we planted have reached the green vegetable standard after being tested by authoritative organs of the state, including the National Bureau of Import and Export Inspection and Quarantine.24 hour intelligent control system plant growth nutrient "continuous supply"

Since it is a closed space, but also to ensure the quality of vegetables, how to provide nutrients and light and other important growth conditions? "All of these achieve computer intelligent control, our control system will automatically adjust the temperature, humidity, carbon dioxide concentration, air circulation, nutrient solution concentration and organic substrate and a series of environmental conditions, one button to start 24 hours running, providing the best growing environment for plants." Facing the reporter's curiosity, He Haiyan said, the system will real-time detect these data, once there is a deviation, it will alarm, we can process in time, precisely because of this, the entire factory only needs two staff can manage.Reporters in the cultivation room to see, three-dimensional cultivation shelves, a row of neat LED emitting red light, reflected on the dense vegetable. "In order to allow plants to better photosynthesis, the company has developed LED lighting technology with independent intellectual property rights, this red-blue composite light has the characteristics of promoting high-quality and high-yield plants, more suitable for plant growth than a single natural light quality." According to He Haiyan, this light source can not only normal cultivation of plants, seedlings and greenhouse application effect is more obvious, but also very energy-saving.
"Not only that, here mature vegetables can be picked directly edible, taste fresh and tender at the same time, but also full of nutrition." He Haiyan told reporters that this is due to the use of hydroponic substrates rich in vitamins a, C and various minerals. Intelligent systems mix water and nutrient solutions in a certain proportion, and then circulate through the pipes on the cultivation rack. The roots and stems of plants under the foam plate can continuously absorb nutrients, which also allows plants to get nutrients. The growth cycle shortened by nearly 1/3.
High quality intensive production leads to high benefit of vegetable planting.
The high quality vegetables that meet the green testing standards are also of considerable benefit. "The vegetable in our factory is not sold by weight, but by tree. The highest selling price of a vegetable can reach nearly 20 yuan." He Haiyan said that the construction area of the plant factory is only 1,000 square meters, but because of the high planting density, the amount of vegetables planted at a time is more than five times higher than the same natural planting area, greatly saving land use. Now the four cultivation rooms have been opened and have entered the stage of full production. At present, more than 60 kinds of vegetables and Chinese herbal medicines such as butter lettuce, red beet and Tianqi can be cultivated, and nearly 600 plants can be produced every day. This data is sustainable.
According to the introduction, there are only a few plant factories like this in the country, focusing on high-quality production of plant factories, from the beginning will be targeted at high-end market sales for major supermarket chains, enterprise units and individuals for targeted sales. "Vegetables produced by plant factories have entered high-end supermarket chains in Chongqing, Shaanxi, Shanghai and Beijing." Xu Zheng, Deputy Secretary of the Party Committee of the District Agricultural Investment Group, said that the annual output value of the Xutian plant factory, which has been put into full operation, will reach 3 million yuan.
"Tongnan is a green vegetable production area, known as the city's vegetable basket, the intelligent development of vegetable production will also provide new channels and new energy for the production of high-quality vegetables." Xu Zheng told reporters that the application of plant factories will undoubtedly become a wind vane for the development of Intelligent Agriculture in Tongnan, with points leading to the surface, radiating the surrounding, driving the intelligent and high-quality development of vegetable production.
