Growing vegetables is inseparable from the soil, which is the common sense of traditional agriculture. No soil is needed to grow vegetables. This is the wisdom of modern agriculture. This kind of wisdom attracted countless eyes at the first intellectual expo. The reporter learned in the interview that the Tongnan District of Chongqing City is supported by the National Agricultural Science and Technology Park, seizes the strategic opportunity of intelligent development of big data, introduces intelligent agricultural enterprises, builds the first plant factory in the city, and plugs in agriculture. The "wisdom" wings transform Chongqing's "vegetable basket" into a "technical basket" and enable "smart agriculture" to empower the economy. Soilless vegetables in the plant factory When traditional agriculture meets intelligent technology, what kind of spark will it hit? Go to Tongnan to see, maybe, you will find the answer there. In the Tongnan National Agricultural Science and Technology Park in Chongqing, the temperature in the Xutian Plant Factory is only about 22 degrees. Thousands of vegetables are growing quietly in a 1,000 square meter cultivation room. The reporter saw at the scene that these vegetables are distributed in several layers of grids, each with its own small grid, with green leaves, which is gratifying. The soil is not visible, and the small grid is filled with nutrient solution for the vegetables to absorb. Plants can't grow without sunlight. Here, tens of thousands of LED light sources replace sunlight. Vegetables grow well without sunlight. The reporter could not enter the cultivation room because of the sterile environment. The on-site staff explained that the cultivation room is constant temperature. Those LED light sources are red and blue composite light, which has the characteristics of promoting high quality and high yield of plants. It is more suitable for plant growth than natural single light quality, which can allow plants to perform better photosynthesis. Graphic-independent How to ensure the normal growth of vegetables? Through intelligent control system, the plant factory monitors and adjusts a series of environmental conditions suitable for vegetable growth such as temperature, humidity, carbon dioxide concentration, air circulation, nutrient solution concentration, and organic matrix in the cultivation room, and provides the best plant in confined spaces Growing environment. Only two staff members can complete these tasks. Without pesticides, these vegetables have a growth cycle of only 25 days. They can be eaten raw, crisp and delicious, and melt in the mouth. Vegetables that come out of the plant factory are not available in the general vegetable market, and basically enter high-end supermarkets, hotels and restaurants, and become ingredients for vegetable salads. If you want to eat, I'm sorry, you can't buy it by the pound. 15 yuan / tree, buy it if you like it. Is this way of growing vegetables a bit magical? In fact, after installing the smart "core" is not magical. Tongnan took this into consideration. In October 2017, Shaanxi Xutian Smart Agriculture Co., Ltd. was introduced to settle in Tongnan National Science and Technology Agricultural Park, and the city's first plant factory was built. In May this year, the plant factory produced the first batch of vegetables, which produced an average of 500 vegetables per day. The market sales were surprisingly good. In addition to the plant factory, in Chongqing Tongnan National Science and Technology Agricultural Park, the vegetables produced by Xingyang Agricultural Company are similar to the plant factory. The company plans to use Internet of Things technology in September to allow vegetables to grow in the air. The technological content of container fish farming The Internet of Things technology is not only used for vegetable cultivation, but also for fish farming. In Guanba Village, Tai'an, Tongnan, in an ecological fish breeding base of more than 500 acres, operators also used Internet of Things technology. The fish pond was excavated in March 2017 and was once a wasteland. Xuyuan Agricultural Company came here and invested several million yuan to build an ecological fish breeding base. Dai Li, the person in charge of Xuyuan Agricultural Company, told reporters that there are about 72,000 fish in the pond. The first batch of ecological fish was sold on September 1 with a total of 4,556 kilograms. A total of more than 20,000 yuan was sold. Before October, it was estimated that the income from selling fish could reach 700,000 yuan. It is not easy to raise so many fish. Dai Li said that the pond adopts the "circulating micro-flow aquaculture in the pond" system, and the water entering the fish tank is treated by static treatment. At the same time, through the sewage processor, the fish manure in the fish tank is discharged for fertilization in the orchard, which fully guarantees the high-quality water quality in the fish pond. At the same time, the staff also uses the Internet of Things measurement and control instrument to monitor the real-time dissolved oxygen, water temperature, PH and other important data of the pond in real time, which can be viewed in the office. If the data is abnormal, the system will alarm and the staff will deal with it in time. Originally, Dai Li and her husband were working on the ginger farming project. The fish farming was a layman for her, but the Municipal Fisheries General Station provided technical support for her fish farming and also provided a container fish farming system. , We will give her timely technical guidance through WeChat every day. Container fish farming is new and the first pilot in the city. Dai Li was very fresh and surprised to see the lively fish swimming in the container. In a few months, the fish in the container will be available for sale. The reporter learned in the interview that the container fish farming system consists of three 2.5-meter-high containers. The processing tank is located between the two farming tanks and contains system components such as physical filtration, biological purification, and ozone sterilization. Firstly, through the physical filtering equipment, the impurities such as feces and bait in the sewage are filtered, and then processed by the microbial filter bed to biologically decompose the harmful substances dissolved in the water, and finally enter the breeding tank after sterilization to realize the circulation of the breeding water body Reuse. Dai Li said that such a farming system has been separated from the "fish pond" model, resulting in safer fish, better taste and nutrition. While achieving zero emissions and zero pollution to protect the environment, it can also reduce the risk cost brought by the weather. Intelligentization empowers Tongnan's agriculture Tongnan is a "vegetable basket" in the main city of Chongqing. The production mode of plant factories and container fish farming has subverted the public's perception of traditional agricultural production and has become a symbol of Tongnan's agriculture towards intelligentization. After agriculture was plugged into the "wisdom" wings, Tongnan National Agricultural Science and Technology Park began to carry the hope of Tongnan Smart Agriculture. Since 2015, under the guidance of intelligent big data, the park has cooperated with Southwest University, Chongqing Academy of Agricultural Sciences and other colleges and units to jointly build a research and development platform, establish a post-doctoral scientific research workstation, hire an expert consultant team of academicians, and introduce agricultural innovation Talents and intelligent agricultural companies, vigorously build new research and development institutions and scientific and technological innovation centers in the field of agricultural science and technology. Since 2017, enterprises in the park have applied the Internet of Things, big data cloud platform, high-tech, etc. to agricultural production, and it has already blossomed. Xutian Agricultural Company, Xingyang Agricultural Company, Xuyuan Agricultural Company, etc. are the representatives. Intelligentization has changed the traditional agricultural production model, and also promoted the development of Tongnan's smart agriculture. In August of this year, at the first Intelligence Fair, Tong Nan released the Big Data Analysis Index for lemon production, which showed the Tong drone, which surprised the audience. Undoubtedly, the Zhibo Fair has added to Tongnan the confidence to vigorously promote the intelligentization of agriculture. At the meeting of leading cadres held in Tongnan District, Secretary of the District Party Committee Zeng Jinghua stated that Tongnan should seize the strategic opportunity of intelligent development of big data, and regard Chongqing Tongnan National Agricultural Science and Technology Park as the foothold and focus of intelligent development of big data 3. Give force to let smart technology empower agriculture. Intelligent promotion of Tongnan's agricultural development has achieved initial results. Jing Bo, deputy general manager of Tongnan Agricultural Technology Company, told reporters that in November this year, Tongnan will demonstrate a "robot picking" system in Shuangba Village, Guilin Street. For the first time, robots pick radishes in the open air. A mobile phone can operate 10 robots. By then, Tongnan's "smart agriculture" will add new elements.
