Intelligent Agriculture: a computer controls more than 800 mu of Park

For vegetable cultivation, appropriate watering and fertilization can ensure the best nutritional environment for crops, and appropriate ventilation and light transmission can create the best climatic environment for crop growth. But how can we achieve the best?

Crops need water for photosynthesis, which comes from soil or substrate. In recent years, Li Wenhu, chairman of Jiangsu Lugang Agricultural Development Co., Ltd., found that by calculating the water content in the soil, we can calculate when crops carry out photosynthesis, so as to judge whether and how much water is supplied.

With regard to fertilization, fertilizers become various ions in the soil and electricity is generated in the process of ion exchange between anions and cations. The change of ion concentration can be measured by measuring the electrical conductivity, so as to determine which kind of nutrition and how much nutrition the crop needs.

Based on these studies, Jiangsu Green Port has developed an automatic water and fertilizer integration system, realizing the ideal state of "vegetables have water to drink when they are thirsty and fertilizer when they are hungry".

Recently, the company's soilless cultivation project manager Wang Xutong said to the author: "our environmental irrigation system realizes intelligent control, through a computer, the entire 800 mu park automatic irrigation, the entire climate intelligent control." According to the crop demand, we set the parameters and operate according to the given parameters every day. One person can do a job that can be done by 10 or dozens of people. "

? Beidou technology is used in vegetable industry.

In the same scientific and technological innovation, Shandong Yunxing Agricultural Science and Technology Company has set its sights on the field of vegetable traceability and applied Beidou technology to the vegetable industry for the first time in China.

At present, Yunxing Agriculture attaches passive high-frequency RFID chip tags to the commodity vegetable packing boxes of Shouguang Lusheng Agricultural Company, writes vegetable brands, categories and other information when vegetables are boxed, and installs an active RFID reader on vegetable logistics vehicles, which is connected with the free access port of fresh agricultural products at highway or toll road toll stations, eliminating the tedious process of on-site inspection and photography, and realizing fast access to read cards.

According to reports, RFID is radio frequency identification, commonly known as electronic tags, is a non-contact automatic identification technology. It automatically identifies the target object and obtains the relevant data through the radio frequency signal, the identification work does not need human intervention, and can work in a variety of harsh environments. RFID can make up for the shortcomings of the QR code management system, such as short-range optical scanning, small information storage and so on. The storage capacity of RFID is ten million times that of QR code, and the speed of reader is more than 100 times that of scanning QR code.

? Greenhouse + high-tech to realize automation and intelligence

What happens when the ordinary greenhouse encounters high technology? The answer is that traditional greenhouses can also be automated and intelligent. There is a fertilizing machine in the soilless cultivation shed of Jiangsu Lugang Agricultural demonstration Park. Shi Li, the person in charge of the greenhouse, said: "this fertilizing machine looks small, but it can manage 150 mu of leafy vegetables, and it can sense the important conditions needed for crop growth, such as temperature, water temperature, pH value, EC value, and so on."

In the soilless cultivation shed of the demonstration park, Zheng Chunzhi, general manager of Shouguang Hongri Seedling Company, has taken a fancy to the computer control equipment of the seedling greenhouse. The computer control system uses various sensors to collect the parameters related to the greenhouse environment (such as air temperature, humidity, light, etc.), and controls all kinds of equipment of the greenhouse according to certain rules, so as to realize the accurate control of the greenhouse environment. "time-saving, labor-saving and labor-saving will be the trend of future development." Zheng Chunzhi said.

"apply the Internet of things technology to traditional agriculture, through mobile platforms or computer platforms to control agricultural production, so as to make traditional agriculture more intelligent." Li Wenhu said.

Wang Leyi, 76, the leader of vegetable greenhouse in Shandong Province, believes that intelligent agriculture is the only way to realize agricultural modernization. With the success of intelligent agriculture, modern agriculture will be realized. (Dai Yuliang is as wide as stone)
