Scientific and technological innovation, green development, vigorously promote conservation tillage

[China Agricultural Machinery Industry News] For agricultural mechanization work, in the past, agricultural mechanization talked about increasing labor productivity and land productivity, as long as agricultural production tasks were completed on time, increasing production and income, and also causing soil erosion and environmental degradation. , causing people to question the mechanization. However, mechanization is also an important means of managing the environment.
Scientific and technological innovation, green development, vigorously promote conservation tillage
“Strengthening the promotion of new technologies such as conservation tillage” is one of the key tasks of this year's agricultural machinery, which is closely followed by the Ministry of Agriculture, focusing on the central task of “strengthening and improving efficiency, stabilizing grain and increasing income”. This has great benefits for the sustainable development of cultivated land.
On March 30th, the 2016 Shaanxi Conservation Farming Forum and “Shaanxi Agricultural Machinery Lecture Hall” with the theme of “Science and Technology Innovation Green Development” was held in Xi'an.
He Cungui, director of Shaanxi Agricultural Machinery Bureau, Liu Xian, executive director of China Agricultural Mechanization Association, Li Hongwen, director of the Conservation Farming Center of the Ministry of Agriculture, Zhu Ruixiang, chairman of Shaanxi Agricultural Machinery Association, and Shi Keji, chairman of Xi'an Ya'ao Agricultural Machinery Co., Ltd. The development of agricultural mechanization innovation, "World Conservation Tillage Development", "Shaanxi Conservation Tillage Development and Innovation" and "Innovative Research on Protective Tillage Special Machines" were exchanged.
Traditional agricultural development methods out of protective farming spring or
"For a long time, the agricultural industry has been pursuing high output growth, and has basically utilized cultivated land and water resources. Although grain production has achieved 12 consecutive increases, it has also paid a heavy ecological and environmental cost." Liu Xian at the forum Expressed concern. The traditional agricultural development mode of fighting resources and consumption has made China's environment and resources “red light”. In the context of over-cultivation of the soil, the promotion of conservation tillage needs to be increased.
In his speech, He Cungui pointed out that the implementation of conservation tillage is a major strategic measure to achieve "grain grain in the land, and grain storage in technology", and is an important way to protect the ecological environment and promote the sustainable development of agriculture. In recent years, Shaanxi Province has adhered to the concept of green development, vigorously promoted the application of conservation tillage techniques, and achieved good ecological, economic and social benefits, which played an important role in increasing agricultural production and increasing farmers' income. "China's agricultural development faces the double extrusion of price ceilings and agricultural resource floors. Many factors have forced the scale of agriculture, and the scale has forced mechanization. The development of agricultural mechanization has ushered in a period of opportunity for transformation and upgrading."
Li Hongwen believes: “Conservative farming techniques have a great impact on Chinese agriculture, second only to cross-regional operations.” In his speech, he introduced the development of conservation tillage in Brazil, the United States, and Europe, such as Brazil’s protection in 1971. The study of sexual farming did not begin to show rapid growth until the 1990s. Argentina and Australia were similar. They did not accept slow acceptance from the beginning, and completed the accumulation of technology in this process until promotion. In comparison, the development of conservation tillage in China, under the joint efforts of the Ministry of Agriculture, the agricultural machinery promotion department and the agricultural machinery management department, will usher in a better development trend in the context of continuous research and development of new machinery and products. "China has changed the grain concept of grain production at all costs, which is a new historical opportunity for the development of conservation tillage." Liu Xian believes.
The management of conservation tillage and the management of enterprises need to work together.
The industry believes that the protective tillage machine has completed the design, production and improvement of the generation of no-till planter, but the development of the second generation no-till planter product with "no problem, can be used, quality and reliability" And promotion depends on the two-way efforts of agricultural machinery enterprises and agricultural machinery departments.
“The industry is grateful to the agricultural machinery companies such as Asia and Australia for their efforts in the research and development of conservation tillage and no-till seed drills.” Li Hongwen said frankly, “For the promotion of conservation tillage, experts can only talk on paper, whether the people really accept it, or It depends on whether the agricultural machinery enterprises can make suitable and useful tools."
Shi Keji, chairman of Asia-Australia Agricultural Machinery Co., Ltd. believes that farmers' purchase of agricultural machinery is largely guided by policies. The direction of subsidies from the state and local governments determines the direction of choice when farmers purchase agricultural machinery. “If subsidies can tilt to the machinery of conservation tillage, farmers have the enthusiasm for purchasing, and they can lay the foundation for the next promotion of conservation tillage in China.”
For the time being, the development of conservation tillage has created an unavoidable problem. According to reports, in 2002, no more than 10 enterprises were producing no-till seed drills. Now, there are more than 135 catalogues of national purchase subsidies in 2015. "On the one hand, we see that enterprises attach importance to this market. On the other hand, in the case of a small area of ​​conservation tillage, there are many similar products and single technology, which restricts the development." Representatives analyzed, the quality of equipment needs to be improved, reliability Low, low efficiency; severe blockage in performance, lack of seedlings and broken ridges; the quality of new machines on the market is mixed, the price difference is large, and there is malicious competition, which are all issues that the industry should pay attention to.
In addition, for the industry's general concern whether "protective farming will cause food production cuts", experts at the meeting believe that conservation tillage itself should not reduce production, but in the actual promotion, it is found that there is indeed a reduction in production, it is certain that conservation tillage It can increase soil water content, especially in the area north of the Yangtze River. Straw returning can increase soil organic matter. It is also an indisputable fact that no plowing land will be produced without arable land. Water and fertilizer are better, and seeds and climatic conditions are the same. Why is it reduced? The quality of the sowing is not good enough, and the equipment is not enough, which is the reason for the reduction in production.
The forum was sponsored by the Conservation Tillage Center of the Ministry of Agriculture, the China Agricultural Mechanization Guide, and the Shaanxi Agricultural Machinery Association. It was co-organized by Xi'an Ya'ao Agricultural Machinery Co., Ltd., and the agricultural machinery management departments and cooperatives from Shandong, Hebei, Liaoning, Ningxia and Shaanxi cities and counties. More than 200 representatives from agricultural machinery companies attended the conference. After the forum, the delegates also watched the product demonstration of Xi'an Asia-Australian conservation tillage equipment.

The stator core of the shaded pole motor is the same as the ordinary single-phase motor.T he stator winding adopts distributed winding,the main winding is distributed in the stator slot. The pole winding dosen`s use short circuit copper ring,Instead, a coarse enameled wire is wound into a distribution winding Embedded in stator slots(About 1/3 of the total slot number).


When the main winding of the shaded pole motor is energized,the pole winding also generates an induced current,the stator flux over the pole winding part of the quilt cover and not part of the rotary part to cover the direction.
