"Chinese Chip" injects new impetus into China's agriculture

　　Experts from the Ministry of Agriculture of China came to Zhangqiu, Jinan, thousands of miles away from Beijing, for research. In the context of the current domestic corn full-process mechanization technology not yet fully mature and the lack of "key cores", the purpose of their trip was only to take a look at the "lineup" of domestic top-level equipment for mechanized corn operations. Let's follow the mobile phone portable editor to learn about the relevant content.

　　At the Huanghuaihai corn full mechanization technology equipment demonstration, the corn high-speed precision seeder equipped with the " China Core " is comparable to the world's top equipment and has achieved intelligent operation; the corn cob and stalk harvesting and baling combine harvester that fills the domestic gap swallows the cobs and spit out square bales... These equipment jointly launched by Shandong Academy of Agricultural Machinery Sciences (hereinafter referred to as Shandong Academy of Agricultural Machinery Sciences) and related companies through industry-university-research cooperation cover the plowing, planting, management, harvesting, drying, and silage links of corn production. It not only demonstrates the major achievements made by China in scientific and technological innovation in the full mechanization of corn production, but also leads the development direction of China's corn machinery.

　　For the Shandong Provincial Agricultural Machinery Institute, which has been working in the agricultural machinery industry for more than half a century, there are more than just these to display. In particular, in the past five years, the institute has repeatedly challenged the commanding heights of agricultural machinery technology. The first high-efficiency and precise garlic planter developed by the institute ended the long-term history of garlic being unable to be mechanized in China. The process equipment designed to automatically produce organic fertilizer using crop straw and livestock and poultry manure has filled the gap in domestic biotechnology for processing vegetable straw. The series of "key technologies and equipment for mechanized production of vineyards" developed by the institute, such as grape ditching, pruning, burying vines, and spraying, meet the requirements of mechanized operations in the main links of grape production and fill the domestic gap... In 2016 alone, the institute won one first prize in the China Agricultural Equipment Innovation Design Competition, one first prize, five second prizes, and thirteen third prizes in the Shandong Provincial Mechanical Industry Science and Technology Award; and won two first prizes and nine third prizes in the Sixth Shandong Provincial Equipment Manufacturing Industry Computer Three-Dimensional Design Competition.

　　How can this "veteran" of agricultural machinery radiate such youthful and passionate vitality? Researcher Fan Benrong, Chairman and Party Secretary of Shandong Agricultural Machinery Institute, gave the answer in one sentence: We always put scientific and technological innovation and market demand first, and the two are closely combined and promote each other. Scientific research is our "rice bowl" and the market is our "food". Based on scientific research, we strive to make independent innovation technology the leader in the industry; guided by market demand, we continuously launch "fist products" that break the bottlenecks that restrict the development of modern agriculture.

　　Independent research and development to equip agricultural machinery with " Chinese chips "

　　Whether a seeder can accurately sow seeds of different shapes and sizes depends on the seeder. As a core component, the seeder has always been an important research direction of precision seeding technology, and the R&D cost accounts for 60% of the whole machine. However, this core technology has always been controlled by European and American agricultural machinery giants.

　　"Due to the lack of core technology, the seeding accuracy and working stability of the seed-metering devices produced in my country under high-speed operation conditions are far behind those of foreign equipment. As a result, the existing domestic high-efficiency seeding machines can only rely on imported seed-metering devices to meet the demand." As the leader of the institute's seeding technology research team, Dr. Shi Song feels deeply about this.

　　To support the research and development work of Shi Song and his team, the institute has invested tens of millions of yuan to build a first-class laboratory in China and purchased a large number of advanced instruments and equipment for these young people to display their talents. Shi Song's team took improving the performance of the seed meter as the starting point of the research and succeeded after thousands of tests. "We have eliminated the complex seed mixing device of the traditional pneumatic seed meter and adopted intelligent drive and control technology, breaking through many core technologies such as 'disturbance efficient seed filling', 'double-sided floating seed cleaning', and 'flexible sealing lubrication'." According to Shi Song, the bench test of the seed meter has verified that the operating speed can reach 12km/h, and the corresponding seed spacing qualified index is as high as 97%, which can gradually replace foreign products.

　　Talent is the foundation of innovation. Whoever has first-class innovative talents will have the advantage and dominance of scientific and technological innovation. The decision-makers of Shandong Agricultural Machinery Institute are well aware of this. In fact, the advent of domestically produced high-quality and efficient seed-metering devices is due to the effective combination of "top talents + high-end platforms". Over the past half century, no less than dozens of similar "China-first" scientific and technological achievements have been born in Shandong Agricultural Machinery Institute. Strong scientific research strength and a good innovation environment have helped it leap to the forefront of domestic local agricultural machinery institutes and become a true "leader".

　　Strengthen applied research to break through intelligent agricultural machinery sensing technology

　　Precision production is an inevitable trend in the development of agricultural modernization, but extensive management in current grain crop production is still a "common problem" that is difficult to eliminate. "In the process of mechanized fertilization, there is a lack of precise control over the amount, location, depth and level of fertilization, resulting in low fertilizer utilization. Mechanized sowing and mechanized irrigation also face similar problems. How can we achieve 'just right'?" Director Sun Yitian of the intelligent technology research team told reporters: "We have found the 'good medicine', which is to rely on intelligence to solve it." It is reported that the institute established an intelligent research team in 2013, becoming one of the earliest institutes in China to enter the field of agricultural machinery intelligence.

　　The bold idea of ​​Sun Yitian's team is to make agricultural machinery and equipment sense the environment and sow, fertilize, irrigate and spray pesticides as "intelligently" as a human brain. Through intensive research, they finally installed self-developed sensors on agricultural machinery, which enable them to detect what is happening above and below the ground at any time, and transmit data to the operation end in real time to receive "commands" from the operator. Due to the outstanding core technology, the corn sowing operation monitoring system and corn harvester row and profiling control system developed by the team won the first prize of Shandong Province's Mechanical Industry Science and Technology Progress Award.

　　"Holding a diamond drill, dare to take on porcelain work." In recent years, the intelligent research team of the institute has taken on the national science and technology support plan project "Development of a large-scale pneumatic corn precision seeding and fertilization machine seed and fertilizer monitoring system" and a number of provincial projects with its good scientific research foundation and innovation ability. It has also worked with relevant leading agricultural machinery companies to develop a number of internationally advanced or domestically leading scientific and technological achievements such as "intelligent high-speed pneumatic corn no-tillage precision seeding and fertilization machine", "intelligent boom sprayer", and "intelligent corn harvester". The promotion and use of intelligent technology will surely bring about a new "agricultural revolution", and Shandong Agricultural Machinery Institute has already stood at the forefront of the trend.

　　Industry-university-research cooperation brings real benefits to farmers

　　After harvesting corn, what should we do with the straw? Burning it will seriously pollute the environment. Although returning it to the field is convenient, returning too much of it to the field will cause the seed germination rate to drop, the roots to be weak, and it will compete with the seedlings for nutrients. Dealing with the straw has become a headache for farmers.

　　"The difficulties encountered by farmers are the precise direction of our scientific research." Director Zhou Jin and his colleagues from the institute's harvesting technology research team started with actual needs and developed and designed a machine that can harvest corn cobs and stalks and baler corn stalks, finding a new way out for the comprehensive utilization of corn stalk recycling. The silage technology research team has developed a green fodder harvester that integrates cutting, crushing, and collecting, providing a relatively complete solution for the recycling of corn stalks. After two years of promotion and application verification, this product has played a huge role in harvesting silage corn and sweet sorghum. In addition, its combined use with balers and silage wrapping machines has greatly improved work efficiency and reduced production costs.

　　Innovation must be implemented to create new growth points. How to produce, promote and apply so that enterprises and farmers can truly benefit? The industry-university-research cooperation model adopted by the institute solves this problem.

　　"For a long time, the cooperation between the institute and enterprises has brought a lot of promotion to our scientific research, such as the research and development results are more down-to-earth, the pace of entering the market is faster, and the funding supply is more timely and sufficient." Jiao Wei, deputy director of the institute, cited several successful cases to reporters: the 4YZX-2 corn harvester jointly developed with Shandong Guofeng in 2011 sold more than 3,000 units; the high-speed precision corn planter, a flagship product jointly developed with Shandong Dahua Machinery, can complete multiple processes such as precision single-grain sowing, extrusion covering, deep loosening, and layered fertilization at one time, and can gradually replace imports; the green fodder harvesting and baling machine jointly developed with Wuzheng Group integrates cutting, crushing, and collection into one, meeting the timeliness requirements of grain-to-feed users for silage corn harvesting. In addition, garlic planters and harvesters have been launched in cooperation with Shandong Maria Company and Shandong Huayuan Laidong Internal Combustion Engine Co., Ltd.

　　"At present, my country's agricultural machinery industry and agricultural mechanization have entered a new historical stage of rapid development. We are also facing new opportunities and challenges of scientific and technological innovation and rapid development. We will give full play to our own advantages, integrate scientific research forces, focus on changing modes and adjusting structures, and solve key scientific and technological problems of full-process mechanization technology and equipment as the main line. We will promote the rapid transfer and transformation of scientific and technological achievements, comprehensively build a full-process mechanization model for agricultural production, and strive to lead the transformation of new and old kinetic energy with scientific and technological innovation. Promote the development of the "new six industries" in agriculture and contribute our wisdom and strength to the realization of agricultural modernization!" The resounding words of Fan Benrong, chairman and party secretary, revealed the ambition and ambition of Shandong Agricultural Machinery Research Institute to stride forward.
