In recent years, with the adjustment of agricultural structure, the development of tobacco, tea, Chinese herbal medicines, fruit trees, flowers and other planting industries has received extensive attention. In this context, it is essential to do a good job in meteorological services for farmers, in order to support these In the development of characteristic agriculture, many small-scale automatic weather stations have been introduced in many areas. With the power of science and technology, big data is used to guide production and protect the development of characteristic agriculture.
The crops planted in the open field are more or less affected by the climatic environment. If the pre-judgment cannot be made in advance, the yield and quality of the agricultural planting cannot be guaranteed. In the event of a meteorological disaster, it will be passive. Disaster losses cannot be avoided. Therefore, to develop characteristic agriculture, it is necessary to create an automatic, efficient and accurate meteorological environment monitoring and early warning network to ensure the safety of agricultural production. The small automatic weather station integrates soil temperature, soil moisture, air temperature, air humidity collection, storage, transmission and management. The important agrometeorological parameters have been included in the monitoring scope, and have achieved remarkable results in meteorological environment monitoring and forecasting. . The application of the system meets the needs of the vast number of farmers for production and living meteorological monitoring, which is conducive to farmers to grasp the agricultural microclimate data information in a timely manner, adopt scientific management measures to guide production, and improve the characteristic agricultural disaster prevention and mitigation, agricultural production capacity and level.
With a small automatic weather station, the forestry and forest microclimates such as cooling, rainfall, and strong winds have long known that early detection and early prevention have greatly improved the initiative of agricultural production. With the meteorological advantages of small automatic weather stations, the use of climate big data to ensure scientific planting, the loss of agricultural disasters has been reduced, and the economic benefits of special agricultural cultivation such as Chinese herbal medicines and flower planting have increased, and the majority of farmers have been delighted, further strengthening the production of scientific and technological agriculture. Information and determination. At present, small automatic weather stations can be seen in orchards, tea gardens, Chinese herbal medicines, and flower planting bases in many areas, and they have fully played the role of “thousands of eyes†in the work of meteorological services for agriculture.
Ethylenediaminetetraacetic acid (EDTA) is an important complexing agent. EDTA has a wide range of uses. It can be used as bleaching fixing solution, dyeing aid, fiber treatment aid, cosmetics additive, blood anticoagulant, Detergent, stabilizer, synthetic rubber polymerization initiator for color sensitive material processing. EDTA is a representative substance of chelating agent. It can form stable water-soluble complexes with alkaline earth metals, rare earth elements and transition metals. In addition to sodium salts, there are also ammonium salts and various salts such as iron, magnesium, calcium, copper, manganese, zinc, cobalt and aluminum, which have different uses. In addition, EDTA can also be used to rapidly excrete harmful radioactive metals from the human body to play a detoxification role. It is also a water treatment agent. EDTA is also an important indicator, but it is used to titrate metal nickel, copper, etc. It must be used together with ammonia to act as an indicator.
