[ China Agricultural Machinery Industry News ] Wang Luofang, Director of the Hunan Agricultural Machinery Bureau: "Hunan is a large rice production area in China and a concentrated area of ​​double-season rice in the country. In the past, the mechanization level of rice production in Hunan has been low. In 2011, Hunan rice cultivation The comprehensive mechanization level was 56.7%, of which the mechanized planting rate of rice was only 4.77%. In 2016, the two data reached 70.6% and 26.98%, respectively, and the average annual growth rate was four consecutive years.†In recent years, Hunan Agricultural Machinery The departments worked together to break through the bottlenecks of these three links and fill in the shortcomings, so that the mechanization level of rice production was rapidly improved.
Hunan Cooperation will rapidly improve the mechanization level of rice production
Twisting the "machine-raising" breakthrough machine insertion bottleneck
The mechanization level of rice production in Hunan has not been high in the past due to the complex terrain, finely divided fields and high requirements for agricultural machinery and operation technology in double-season operations. Wang Luofang said: "Our research found that the bottleneck restricting the promotion of machine transplanting lies in the breeding process. To this end, we put forward the concept of 'machine-raising', that is, breeding seedlings suitable for machine insertion; and formulating rice transplanting rice in line with Hunan farming system. Mechanization Technical Specifications, "Standards for Rice Breeding Soft Hard Disks", and compiled and compiled "Hunan Province Rice Seedling Mechanization Technology Demonstration and Promotion Data Handbook", distributed to the agricultural machinery departments of all cities and counties in the province, and laid a large-scale promotion machine transplanting in the province. Good foundation."
It is understood that Hunan has been swaying for four consecutive years, "mainly attacking the machine, pushing the large-scale purchase, demonstrating at different levels, and strengthening technical guidance." The four links are not relaxed. Each year, thousands of "machine-raising" experts are trained. Drive more farmers to use the machine transplant technology spontaneously. Wang Luofang said: "On the provincial level, there are 2,000 person-times of training cooperatives and township agricultural machinery technicians every year. All cities and counties organize training of agricultural machinery cooperatives, large agricultural machinery, large grain farmers and agricultural machinery. Every year, 70 counties are selected for machine transplanting. Demonstration, the effect of the propaganda machine on the increase of production. After several years of training demonstration, the technology of 'machine-raising' has been basically mastered, and rice machine insertion technology has also been rapidly popularized."
Changsha County's modern machine transplanting and breeding demonstration center is located in the Tongzhan Agricultural Machinery Professional Cooperative of Wangjingyuan Village, Jinjing Town, the county. It is a concentrated rice breeding center with large area, high standard and large number of service farmers in Hunan Province. On the March 17th, the rice paddy factory in Yuji, the company, signed a meeting for the supply of more than 450,000 plates (about 10,000 mu of field). After that, due to limited production capacity, it only received more than 240,000 plates. (about 5,300 acres of field) breeding orders. Huang Long, the chairman of the cooperative, told the reporter that “the bottleneck of rice machine insertion is mainly the two problems of seedling quality and variety growth period. Now there are varieties suitable for machine insertion in the market, but there is still a great technology for breeding high quality seedlings. Bottlenecks. The quality of seedlings cultivated by our factory is not only better than that of traditionally cultivated seedlings, but also fully automated and intelligent breeding can save more than 20% of seed and more than 60% of labor costs. Large households buy sprouts and seedlings. The three methods of all-inclusive breeding and transplanting are more than 25 yuan, 30 yuan and 40 yuan respectively.
Different from Ultrasonic Heat Counters,The Smart Heat Meters are used
for heat and cold energy calculation through the water. The smart Heat Meters
can display the accumulated heat, flow rate, instant flow rate, inlet water temperature,
outlet water temperature, temperature difference and etc.
The smart heat meter
is suitable for measuring the heat exchange, known as the heat transfer fluid
or liquid absorbing thermal energy conversion equipment, which consists of a
flow sensor, temperature sensor and heat calculator(Heat Meter Counters) three parts. The smart heat
meters are also known as smart energy meters.
The smart heat meter is
used to measure and display the water flow through the heat exchange system
release or absorb heat. The smart heat meters are installed at the inlet pipe
or outlet pipe to measure accurate metering and intelligent control of charges
of the heat consumption. Its working principle is to install the smart heat meters
in the heat exchange system, when water flows through the system, according to
the supply and return water flow temperature, from the data from the flow
sensors and temperature sensor as well as the water flow time, the smart heat meter
will calculate the released and absorbed energy through the calculator.
