[China Agricultural Machinery Industry News] Modern agriculture widely applies modern science and technology, modern industrial production materials and scientific management methods of social agriculture. In the history of agricultural development divided by the nature and condition of agricultural productivity, it is agriculture at a new stage of development. As the important grain-producing area of ​​China, Changchun, the “grain granary” under the jurisdiction of Yushu City has ranked first in the country for many years. During the “Thirteenth Five-Year Plan” period, Changchun will build a national modern agricultural model area to realize agricultural modernization.
Changchun will build a national modern agricultural model area

A few days ago, the agricultural plant protection drone newly purchased by Zhongyi Agricultural Machinery Professional Cooperative of Nong'an County, Changchun City was tested. “The test flight was very successful, and it was a big skill when it was sprayed.” Director Wen Yesheng said that with it, the production efficiency will be greatly improved. “Single spray, artificially spray 1 hectare for two hours, 1 day for the overhead car. Spraying 20 hectares, the aircraft can spray 100 hectares a day."
The fertile plains in the west and north of Changchun are suitable for grain production, and the development of modern agriculture is good and the prospects are good. Changchun started a modern large-scale agricultural comprehensive experimental area with a cultivated area of ​​103,000 hectares and 128,000 hectares in Yushu City and Nong'an County, and cultivated the modernized experimental area of ​​radiation of 17,000 hectares of paddy fields in the Songhua River Basin. .
Changchun has spared no effort in investing in modern agricultural production systems in recent years. In the Songmu Irrigation District with more than 20,000 hectares of arable land, the contiguous paddy fields are full of greenery until the “skyline”. “Since 2011, we have invested 200 million yuan to renovate the Songmu Irrigation District, and the canal system is smooth.” Liu Fengguo, deputy director of the Dehui City Water Conservancy Bureau, said that the time from the first pumping station to the end of the channel has been shortened from the past two days to one day. Half, the water use factor increased by 10%.
Moderate scale operation is the only way for modern agriculture. Xie Dalin, manager of the Changhe Agricultural Machinery Planting Professional Cooperative in Zhangshu City, which operates 310 hectares of arable land, said, “After the centralized operation of the land, the intermediate links will be skipped and the goods will be directly purchased from the manufacturers, which will greatly reduce the investment in production materials.” Seed, fertilizer, Xie Dalin saved 300,000 yuan than “buy-out”. “Each per hectare of cultivated land only has fertilizer input and mechanical production. The cost savings of “one household” is nearly 1,000 yuan. The difference is the profit generated by science and technology and scale operation for cooperatives.”
At present, the proportion of rural land transfer in Changchun has reached 28.5%, and will increase by 4% during the year. This year, Changchun will focus on cultivating a number of new agricultural business entities, adding 500 professional farmer cooperatives, 500 family farms, and training 5,000 new professional farmers.
The integration and development of the first, second and third industries is an important part of the transformation of agricultural development mode. Cucumbers, tomatoes and fungus are being harvested in the two sub-village leisure agriculture parks in Nong'an County. “There are 63 greenhouses in the park, and 157 villagers are employed here.” Yu Wenxia, ​​secretary of the Party Branch of the two sub-villages, said that the green fruits and vegetables produced in the park have already entered the supermarkets in Changchun. Fruit and vegetable greenhouses are only planned for Wenxia. "We are stepping up publicity to attract more citizens to the park to pick and experience farmhouse music. At the same time, agricultural products processing plants such as bean processing plants and corn flour mills are also under construction, one, two and three. Industrial integration development will directly drive villagers to increase their income."
According to the "Chongqing City Realization of Agricultural Modernization Master Plan", by 2020, Changchun will basically realize agricultural modernization, realize the whole process of mechanization of dryland and paddy field production, and the output value of agricultural products deep processing industry will exceed 300 billion yuan to create a fusion of primary, secondary and tertiary industries. The modern urban agriculture circle focuses on the construction of 100 urban agricultural demonstration projects.

Filter Softener Valve

These control valves play a crucial role in ensuring the efficient and effective operation of water treatment systems.
Filter valves are responsible for controlling the filtration process, which removes impurities and particulate matter from the water. They can be further classified based on their control methods, such as manual, semi-automatic, or fully automatic.
Softening valves, on the other hand, are designed to remove hardness-causing minerals like calcium and magnesium from the water. They can be categorized based on the number of tanks controlled by a single valve, such as single tank or multi-tank systems.
Additionally, softening valves can be classified based on the automatic regeneration method used. This includes time-based regeneration, meter-based regeneration, or demand-initiated regeneration.
The flow direction of the regeneration liquid is another factor that determines the type of softening valve. It can be either downflow, upflow, or counter-current flow.
The control method of softening valves refers to how the valve is operated and controlled. It can be manual, semi-automatic, or fully automatic, depending on the level of automation and control desired.
In industrial applications, softening valves are commonly used for treating boiler feed water. The removal of hardness-causing minerals helps prevent scale formation and improves the efficiency and lifespan of the boiler.
