[China Agricultural Machinery Industry News] In the Yanzhao land in May, wheat began to grow and grout, which is a crucial period of agricultural production. Han Changfu went deep into the fields, villages and farms of some counties and cities in Chenzhou City and Shijiazhuang City, and talked with wheat experts, cadres and other people to understand the adjustment of agricultural structure, agricultural water saving, wheat field management and other related work, and listened carefully to your opinions and suggestions. Han Changfu: Focusing on Optimizing and Adjusting Agricultural Structure, Paying Attention to Summer Grain and Oil Production, such as Wheat
From May 7 to 8, the Minister of Agriculture Han Changfu emphasized in the investigation of Hebei that the agricultural departments at all levels should conscientiously study and implement the spirit of the important speech delivered by General Secretary Xi Jinping at the rural reform symposium hosted by Xiaogang Village, Fengyang County, Anhui Province. Vigorously promote the structural reform of the supply side of agriculture, focus on optimizing and adjusting the agricultural structure, coordinating the management of the wheat field, and making every effort to capture the good harvest of summer grain and oil; the groundwater over-exploitation area should reduce the water reduction and structural adjustment, and explore the farmland rotation for fallow In combination with the system, on the basis of stabilizing the production capacity of the core food area, we will develop agricultural industries that save water and increase efficiency and are suitable for production, and promote sustainable development of agriculture.
In the land of Yanzhao in May, wheat began to grow and grout, which is a crucial period for agricultural production. Han Changfu went deep into the fields, villages and farms of some counties and cities in Chenzhou City and Shijiazhuang City, and talked with wheat experts, cadres and other people to understand the adjustment of agricultural structure, agricultural water saving, wheat field management and other related work, and listened carefully to your opinions and suggestions.
The adjustment of agricultural structure is the main theme of this year's agricultural work. It is related to the sustainable development of agriculture and the increase of farmers' income. Han Changfu is very concerned and specially came to the groundwater over-exploitation area to understand the adjustment of agricultural structure. In Le Shou Town, Xian County, Zhangzhou City, Han Changfu went into the rapeseed field of Ziya Huahai and talked with the growers to see the cultivation of dry rapeseed. The grassroots cadres introduced that the county used the groundwater over-extraction treatment project to carry out the planting structure adjustment pilot, and gave the rapeseed growers a subsidy of 400 yuan per mu to build a 10,000-mu “canola oil sunflower†continuous cropping agricultural tourism belt. The rapeseed oil sunflower is continuously cropped, reducing irrigation by 2-3 times a year, and saving more than 100 cubic meters of water per mu, achieving ecological water conservation and increasing farmers' income. Subsequently, Han Changfu came to the Juntai Family Farm in Bazhang Village, the 15th-level township of Xian County, to understand the seasonal fallow situation of the groundwater over-exploitation comprehensive treatment project. Zhao Juntai, the person in charge, said that the farm implemented 870 mu of agricultural planting mode project, and subsidized 500 yuan per mu. The wheat and corn companies were changed to fall season and one season of rain, and the annual irrigation was reduced by 3-4 times. Cubic meters, after project implementation, the income is slightly higher than before implementation. Han Changfu pointed out that adjusting the planting structure is an important way and measure for groundwater over-extraction. While exploring and researching water-saving and water-reducing, it is also necessary to reduce the income of farmers and achieve the goal of protecting the agricultural resources and environment, stabilizing production capacity, and increasing revenue. It is necessary to carry out pilot rotation system in groundwater over-exploitation areas, and form an effective long-term mechanism through pilots to ensure that the good momentum of water saving and income increase will not be reversed after the end of the implementation period of groundwater over-exploitation projects. It is reported that in order to promote agricultural water conservation, Hebei Province has implemented a seasonal fallow trial in the groundwater funnel area of ​​Heilongjiang this year to reduce the winter wheat by 1.04 million mu, from winter wheat and summer maize to two-year-old cooked corn, miscellaneous grains and miscellaneous. Beans and other crops.
Malan Farm, Xinjiantou Town, Xinji City, under the jurisdiction of Shijiazhuang City, is the wheat variety test base of Shijiazhuang Academy of Agriculture and Forestry.
Han Changfu went into the wheat water-saving variety breeding base and the new variety display field to check the growth of wheat with different varieties of different watering times, and asked about the water use and output of water-saving varieties. Guo Jinkao, a researcher at the Agriculture and Forestry College of Shijiazhuang City and a wheat expert, is doing experiments in the field. Han Changfu has in-depth discussions with him about wheat production every year, calling him "a friend in the wheat field." Guo Jincao led Han Changfu and his entourage into the large pit dug in the experimental field to understand the growth of water-saving wheat roots through the soil profile. When I learned that there is little difference in the yield of water-saving and pouring water, Han Changfu showed great interest in the water-saving varieties they selected. I hope that the researchers will continue to cultivate more drought-resistant and water-saving wheat varieties and strive for wheat production. It is able to reduce water consumption without reducing production, lowering costs, alleviating pressure on resources and environment, and striving to make grain and land for grain and technology. Han Changfu pointed out that agricultural water saving is a big issue. We must adhere to the combination of promoting water-saving varieties and agronomic water saving, engineering water saving, and planting structure adjustment to improve water resource utilization and improve agricultural efficiency. At present, when wheat production enters the key stage of growth in the middle and late stages, the agricultural sector should increase its guidance services, pay close attention to the implementation of key measures, strengthen field management, and vigorously carry out the “one spray three prevention†of wheat, the number of preserved grains, and the increase in grain weight. Do a good job in maintenance work such as agricultural machinery, fully prepare for wheat harvest, and strive for a good harvest of grain and oil this summer.
Coalescence &Separation Filter Elements
Describe:
The coalescence separation filter element is generally cylindrical in shape, and the coalescence separation filter element is used in the oil-water separation system, mainly separating the oil-water mixture, suspension solution, emulsion solution, etc. The application flow of coalescence separation filter in the system can be divided into solid-liquid separation-demulsification-coalescence-separation. In the system, the number of Coalescence Filter and separation filter is better than that of 3:1, the effect of coalescence is good and the separation speed is fast.
Principle and characteristics:
The surface treated glass fiber or polyester fiber is mainly used as the coalescence medium. The structure of the Filter Material is 0.1 μ m by special design. The filter medium has good coalescence performance. Working process: after the emulsified oil enters the coalescence separator, it first enters the inner filter core from inside to outside, and the small liquid droplet in the dispersed phase changes from small to large. Finally, it falls off on the surface of the coalescence filter core and completes the coalescence process. In the process of flow separation, the larger water drops sink into the sink by gravity, and the small water droplets flow along with the oil to separate the filter elements. The separation filter has hydrophilic effect to block the passage of water. Small water beads collide to form large water droplets, which then settle into the sink again, thus dehydrating the oil.
Different packing sizes should be selected according to different oil-water systems: the smaller the packing size, the larger the specific surface area per unit mass and the larger the contact area with droplets. As a result, the performance of the coalescence filter element is enhanced. Therefore, it is suggested that the separation efficiency of coalescence filter should be taken into account when choosing fiber size, and the pressure drop should be taken into account at the same time.
Range of applications
