  Agriculture is in a critical period of transition from traditional agriculture to modern agriculture, and people's demand for food and other major agricultural products is increasing. And high-standard farmland has become an important measure to implement the strategy of "holding grain in technology, and grain in land" to ensure national food security.

  
  In the construction of high-standard farmland, the utilization of water resources is the key, so one of the "high-efficiency water-saving and precise irrigation" is to improve the utilization rate of water resources. In terms of high-efficiency water-saving and precise irrigation, in order to formulate a scientific and effective irrigation method, it is necessary to first understand the soil moisture situation, combine with the characteristics of plant growth, control the amount of water reasonably by the intelligent irrigation system, and use irrigation methods such as sprinkler irrigation and drip irrigation, thereby To achieve precise and efficient irrigation.

  
  Soil moisture is an important index parameter for understanding soil environmental changes. Its quality is very important to agricultural production. It is related to the selection of production activities and measures such as spring sowing, fertilization, and drought resistance. and the economic yield of crops. Therefore, the multi-layer soil moisture sensor has an efficient, accurate and effective soil moisture monitoring equipment, which can realize real-time automatic collection and storage of soil moisture data, and can automatically upload the collected information to the agricultural management cloud platform at regular intervals. It can timely understand the excessive, suitable, lack and serious lack of soil moisture in the monitoring area, make drought forecast in time, provide farmers with scientific sowing and irrigation opportunities, and provide scientific theoretical support for the realization of sustainable agricultural development. give full play to its guiding role.

  
  Why is it necessary to monitor soil moisture at different depths?
  On the one hand, different plant roots grow to different depths in the soil, and on the other hand, due to the different growth stages of plants, the root system does not move at the depth of the soil extension. Therefore, in order to ensure the accuracy of soil monitoring, multi-depth detection is added.
  Secondly, through data analysis, when the water content of the shallow layer is much higher than that of the deep soil, and the content change is relatively slower than normal, it indicates that the soil structure is poor and the water infiltration is poor, and the soil needs to be loosened to ensure that the plants can fully obtain the Moisture is required.

  
  The multi-depth soil moisture sensor is a high-precision, high-sensitivity sensor that measures soil moisture using high-frequency electronic technology. By measuring the dielectric constant of soil, it can directly and stably reflect the real moisture content of various soils, and can measure the volume percentage of soil moisture. Easy to install, suitable for water-saving agricultural irrigation, meteorological monitoring, environmental monitoring, greenhouses, flowers and vegetables, grassland pastures, soil rapid testing, plant cultivation, scientific experiments and other fields.

  
  Establish a smart agricultural management platform, and build an intelligent irrigation system with multiple deep tube moisture poles, flow meters, solenoid valves, water pumps, and liquid level sensing equipment. There are moisture poles to monitor soil moisture. Automatically control the water pump, open the water valve in the required irrigation area for irrigation, and automatically stop irrigation when the soil moisture content reaches a normal value; at the same time, the agricultural management platform intelligently analyzes the water consumption of each irrigation, and takes the best irrigation water value. The amount of water used for secondary irrigation is controlled, so as to achieve precise irrigation.

  
  Multiple deep tube moisture sensors monitor farmland soil moisture in real time, combined with intelligent irrigation equipment, to achieve precise irrigation, improve water utilization, and reduce water waste. In irrigation, remote automatic or timed irrigation can be realized to improve irrigation efficiency and reduce labor costs.

  Posted in the topic The Necessity of Constructing Campus Weather Station in the forum Technology

  December 15, 2021 3:11 AM EST

  The construction of the campus weather station has played a positive role in promoting the popularization of meteorological science. Take meteorology, environmental science, and astronomy as the frontiers of meteorological science popularization, integrate meteorology, environmental protection, astronomy and other content into the meteorological education curriculum, while promoting the concept of meteorology and environmental protection, let students feel the fun of meteorology .
  The school sets up a weather station, which allows students to feel the changes in the weather at a close distance and understand the natural laws of various weather changes. At the same time, students can also learn about the air pollution problem, so as to strengthen students' environmental awareness.
  Various sensors can collect, store and display elements such as air pressure, air temperature, relative humidity, wind direction, wind speed, rainfall, solar radiation, and air quality.
  The purpose of the campus weather station is to monitor campus weather data. The collection of the campus weather station weather data depends on sensors. The campus weather station is composed of three parts: automatic weather observation station, manual observation instrument, and popular science data application platform. The automatic weather observation station mainly includes: data acquisition system, sensor system, power supply system, transmission system, mechanical accessories, etc., which can automatically and intelligently collect weather data. Manual observation and measurement instruments include: maximum temperature gauge, minimum temperature gauge, dry and wet bulb temperature gauge, low temperature gauge, rain gauge, evaporating dish, hair hygrometer, handheld anemometer, etc., to directly observe real-time meteorological data. The popular science data application platform includes: outdoor LED display and indoor advertising machine publishing terminal, mobile phone APP and server data analysis terminal.
  After the completion of the campus weather station, students will be taught popular sciences on meteorological science and general knowledge of meteorological observation. The automatic weather station of the school is equipped with electronic display screens, which can display the data collected by the campus weather station in real time, attracting many meteorological enthusiasts to actively participate in popular science learning activities. Enhance students' awareness of disaster prevention and mitigation. For more detailed equipment information about the campus weather station, you can leave a message to communicate at any time.
