The retaliatory cooling strikes, the weather station guides agriculture to cope with the "cold spring"
As of yesterday, consecutive days of southerly winds made Jinan's spring "hu" all at once, and the word "hot" was highlighted when going out at noon, so that the real-time temperature at noon on the 21st actually reached 24°C. However, this spring-like warmth is really short-lived. The weather station has issued blue cold wave warnings and rain forecasts, and the cliff-like "falling spring cold" is about to hit.
Since December last year, precipitation in the winter wheat area has been 50% to 80% less than that of the same period in normal years. In addition, the wind is relatively strong, the soil surface moisture is insufficient, and local droughts have appeared. At the moment when the wheat water demand peaks and the critical period of spring field management, there is another "falling spring cold". At this critical moment, I hope farmers friends can pay close attention to the changes in the weather, through reasonable regulation and equipment monitoring, and implement drought-resistant and seedling protection measures according to locality and time.
Combination of traditional agriculture and equipment agriculture.
In harsh environments, farmers must not only combine traditional farming methods, but also keep pace with the times and move closer to equipment agriculture. Equipment agriculture is an extension of traditional agriculture. With the support of agricultural weather stations, soil sensors, water and fertilizer integrated machines, and other equipment, with the Internet of Things technology, agricultural planting can be free from natural constraints and increase profits.
Ways to protect seedlings and raise seedlings :
1. Promptly carry out early spring suppression of squatting seedlings in Wangchang wheat fields to achieve growth control;
2. Timely topdressing weak seedlings, rationally regulate fertilizer and water, promote seedling transformation and upgrading, and improve cold and frost resistance.
3. Water in time before cooling down to improve soil moisture, adjust the microclimate near the ground, reduce the variation of ground temperature, and prevent freezing damage in early spring.
4. For wheat fields suffering from freezing damage, timely topdressing appropriate amount of nitrogen fertilizer and timely watering can promote the recovery of frozen wheat growth.
Agricultural Meteorological Station
Agricultural meteorological station is a representative product of equipment agriculture. It is composed of sensors, data acquisition and transmission system, data cloud platform, power supply and network system. The agricultural weather station can monitor temperature and humidity, wind speed and direction, atmospheric pressure, rainfall, illuminance, total radiation, carbon monoxide, carbon dioxide and other meteorological elements, and provide guidance for agricultural production through mobile phones and computer terminals.
The components of the
agricultural weather station The five components of the agricultural weather station include: bracket and sensor part, GPRS/4G data upload, solar panel and battery part, collector and transmission module part, background computer terminal part.
**Support and sensor: **The main function of the support is to place equipment, such as sensors, solar panels, collectors and transmission modules, etc. The main function of sensors is to monitor the elements of the road environment.
Solar panels and accumulators: The main function of solar panels and accumulators is to provide power support. The accumulators are charged through solar panels, and the accumulators release power to ensure the operation of the equipment.
**GPRS/4G data upload: **The outdoor agricultural weather station is based on GPRS communication technology to realize automatic data upload. The road automatic weather station has a multi-function GPRS communication interface. First, insert the mobile phone card of China Mobile or China Unicom into the card slot, and then put the GPRS antenna outside the waterproof box to ensure that the communication signal is not shielded. When the weather station is working, it sends real-time weather data to the environmental monitoring cloud platform through the GPRS signal timing (1S~10000S/time can be set) to realize the functions of real-time data display, data exceeding alarm, remote monitoring, data storage and download.
** Collector and transmission module: ** The main function of the collector and transmission module is to collect the meteorological element information monitored by the sensor, and then transmit it to the background computer through the transmission module.
**Environmental Monitoring Cloud Platform: **The main function of the background computer terminal is to display and store data.
Features
of agro-meteorological station 1. The agro-meteorological station can establish an agricultural disaster early warning system to reduce agricultural disaster losses. By configuring corresponding sensors on the agricultural meteorological station, environmental data can be monitored in real time. When the set warning value is reached, an alarm message will be issued to remind the administrator to take corresponding measures to reduce losses caused by agricultural disasters.
2. Monitor climate factors, soil physical and chemical properties, and combine the physiological and ecological characteristics of crops to accurately grasp the timing and amount of fertilizer application; avoid environmental pollution, reduce ineffective irrigation, and save agricultural water.
3. Through real-time uploading of data, a remote management mode can be used to reduce the number of management personnel and labor intensity, solve the problem of continuous shortage of agricultural labor, and reduce agricultural costs.
4. The equipment is easy to install, which is convenient for later upgrade and maintenance.
With the rapid development of science and technology, the relationship between my country's agricultural development and agricultural weather stations will become closer and closer, real-time monitoring of weather changes through equipment, emphasis on warmth, frostproof, and windproof reinforcement, so as to prepare for the advent of China's equipment agriculture.
