Optimize China's "land advantage" conditions to drive the development of agricultural machinery industry
[China Agricultural Machinery Industry News] Many Chinese people pay attention to "day, place, and people." The upcoming "Tian Shi" in 2016 is not very good for agricultural machinery and even the agricultural industry. After all, "Tian Shi" is difficult to be controlled by manpower. Only "land" and "human harmony" are greatly affected by people's behavior and will. The “land†environment is an important factor in the overall operation of the agricultural machinery industry.
Optimize China's "land advantage" conditions to drive the development of agricultural machinery industry
415.8 billion yuan invested in improving "land profit"
Hu Hengyang, inspector of the Rural Economic Development Department of the National Development and Reform Commission, said that during the “Twelfth Five-Year Plan†period, the finance, land, agriculture and other departments have integrated about 130 billion yuan to build 400 million mu of high-standard farmland, with an average increase of 10% to 20% per mu. . By 2020, 800 million mu will be built to secure 1 billion mu of high standard farmland. The total area of ​​large-scale irrigation districts in China is not large, but it produces one-quarter of the country's grain and contributes one-third of the total agricultural output value. During the “Thirteenth Five-Year Plan†period, we will transform 4,300 large-scale irrigation districts and more than 2,500 medium-sized irrigation districts to develop an effective irrigation area of ​​1 billion mu.
Recently, the Ministry of Water Resources organized and issued the “2016-2017 National Winter and Spring Farmland Water Conservancy Fundamental Construction Implementation Planâ€, which determined the overall requirements, main indicators, implementation priorities and safeguard measures. It is understood that this year's winter and spring national farmland water conservancy basic construction plan completed a total investment of 415.8 billion yuan, farmers invested 3.597 billion, put in machinery 325 million sets (sets), completed earth and stone volume of 11.034 billion cubic meters; repair water damage damage water conservancy There are 268,000 projects, 47,000 kilometers of dredging rivers, 368,000 kilometers of dredging ditches, 337 new pumping stations, 4811 reservoirs and dams, and 258,000 roads in Qiangtang. It is estimated that the area of ​​farmland will be increased by 13.83 million mu. The newly-added irrigated area was 29.28 million mu, the newly-improved area for removing mites was 38.99 million mu, the area of ​​medium- and low-yield fields was 19.05 million mu, the area of ​​newly-added water-saving irrigation project was 40.21 million mu, and the area of ​​soil erosion control was 34,700 square kilometers.
“District†helps “large-scale†of agricultural machinery products
With the acceleration of the rural land transfer process, more farmland will be concentrated and contiguous, which is more suitable for large-scale operation of agricultural machinery. Only when farmland is gradually concentrated, large and medium-sized agricultural machinery may be useful. The continuous upgrading of the harvesting of the harvester is the confirmation of the results of the centralized contiguous crops. After the investment in farmland and water conservancy facilities in this winter and spring, the scale of land contiguous will definitely be further enhanced.
Take the self-propelled wheel wheat machine as an example: in 2012, the main selling model was 2.5 kg of feed product, representing the product of the Levo GE25; in 2013, 4 kg, representing the product Levo GE40, the same year GE50 also began to sell; 2014 In the year, 5 kg and 6 kg products became the main models of wheat machines. 89.5% of the sales of Revo wheat machines were GE50 of 5 kg products, while the main products of Zhonglian were marked as 6 kg. In 2015, 6 kg and 7 kg became the main models of wheat machines. The Lovol GE60 and China United TB50 showdowns were the highlights. By 2016, the Revo GE70 and the China United TB60 have increased the feed to a level of 7 kg. At present, Leiwo, China United, New Research, and China Enterprises have already had 8-10 kg models.
Take the self-propelled crawler rice machine as an example: in 2012 and 2013, the main sales model is 2.0-2.5 kg feed product, which represents the product of Kubota's PRO688Q and Starlight's 2.0D; in 2014, except for Starlight and Kubota, the rest of the domestic sales The top ranked Volde, Lovol and Zoomlion are mainly 4 kg products; in 2015, the starlight is also 4.2 kg, 3.6 kg starlight to Ding 4.0 as the main sales model, Kubota 4.5 kg products are also test. In 2016, the major rice machine manufacturers hit a total of 5 kilograms.
"Geo advantage" factors determine different modes of agriculturalization
Regardless of the scale of rural land transfer in China, it must be influenced by the unique geomorphological features of each region. Therefore, the geomorphological characteristics are important factors affecting the situation of the agricultural machinery industry. If we compare the landform characteristics of China's major grain producing areas with the global agricultural developed countries, we may see blueprints for different regions in 2017 and even a longer period.
China's Xinjiang, Heilongjiang region and some farms, farms and other large arable land, similar to North America, suitable for large-scale power, machinery, automatic navigation operations; China's Huanghuaihai area, Weihe Plain, Hetao area, similar to Europe, suitable for large and medium power , the operation of the middle machine; the paddy field in southern China, similar to Japan, suitable for medium-sized, small-powered, medium-machined operations.
It is not difficult to see that the development of China's agricultural machinery products is not only a "large-scale" trend. Small and medium-sized agricultural machinery in the southern and hilly mountainous areas is also a development direction, especially in the southern paddy fields and terraced areas. It is also an important staple food for the Chinese people - the importance of rice. Production area. Sichuan Gangyi, Laizhou Jindawei and other production enterprises have taken this small seam field as the research and development direction and gradually gained a firm foothold in the market. However, due to the low profit margin of such products, they are not concerned by large and medium-sized enterprises with research and development capabilities, and the development speed is not fast.
Concluding remarks: After the investment of 415.8 billion yuan in the construction of farmland and water conservancy projects in the winter and spring this year, China's “land profit†trend will become more obvious, and the scale of agricultural machinery will be smoother.
