On the past Double Eleven, Shen Xiaofen, an agricultural mechanic of Zengcheng Shixiang Agricultural Machinery Professional Cooperative, walked into the live broadcast room and enthusiastically promoted his agricultural products to the audience.
Petite and slender, wearing glasses, looking quiet and well-behaved, is Shen Xiaofen's initial impression of the outside world. If you don't see it with your own eyes, it is difficult to believe that this "post-95" girl is actually an agricultural machine expert who deals with large agricultural machinery equipment and drones every day.
From "going out to pursue dreams" to "returning to hometown to build dreams", more and more ambitious young people are returning to their hometowns to practice new ideas and new technologies in the fields to help agricultural products cross thousands of mountains and rivers and move towards a broader market.
To achieve common prosperity, rural revitalization is the only way, and the arrival of young people has revitalized the countryside, and more importantly, they have also brought new technologies to push smart devices into mechanized blank areas. Behind them, rural revitalization is showing vitality.
Holding the "bull's nose" of rural revitalization
Rural revitalization and modern agricultural equipment are the key.
As early as 1959, China put forward that "the fundamental way out of agriculture lies in mechanization", which pointed out the direction for the road of agricultural development.
The prototype on the third set of RENMINBI "One Yuan" coupons issued in 1962 was Liang Jun, China's first female tractor driver.
In December 1976, the People's Daily editorial "The Fundamental Way Out of Agriculture Lies in Mechanization" foresaw that with the process of social urbanization, the rural population is getting smaller and smaller, and how to cultivate more land with less manpower has become a major problem.
After so many years of continuous appeal, do you think that the degree of mechanization of Agriculture in China is already very high? Actually not, there are still a lot of blank areas.
Relevant data show that in 2018, the mechanization rate of potato planting and harvesting in the dryland area was only about 25%, the mechanization rate of cotton picking was only 41%, and the comprehensive mechanization rate of fruit and tea was only 25% and 28%, respectively. There are 8 hilly mountainous provinces with a comprehensive mechanization rate of less than 50% in crop cultivation and harvesting, and 2 southwest hilly mountainous provinces with less than 30%.
According to data from the National Bureau of Statistics, in 2019, the total area of orchards in the country was 184 million mu, and the production operations in many places and many links also relied on manual labor, on the one hand, the variety of forest fruits and the complex planting environment were the reasons for the low level of mechanization of orchard operations. On the other hand, it is because the effective supply of orchard machinery is insufficient, and the promotion and popularization of orchard machinery are not enough.
Even in Guangdong, a large number of fruit trees are planted, from planting to harvesting, almost many environments are still manual operations. For example, farmers like to plant rice with flood irrigation, and there are many fertilizers, but in fact, a lot of fertilizer is wasted.
The "cow nose" of rural revitalization is still in mechanical modernization.
According to the "Major Challenges and Strategic Tasks Facing agricultural mechanization in the 14th Five-Year Plan" issued by the Development Planning Department of the Ministry of Agriculture and Rural Affairs, it is of great significance to deeply understand the relationship between mechanization and agricultural modernization in the new era and to give better play to agricultural mechanization, which is of great significance to the supporting role of agricultural and rural modernization and rural revitalization goals.
Also in accordance with the "Strategic Plan for Rural Revitalization (2018-2022)", China must realize the full mechanization of the whole agricultural process by 2035, and provide material equipment and technical support for the realization of agricultural and rural modernization and rural revitalization goals.
Just recently, various places have been spending great efforts to promote "high-standard farmland construction projects", in fact, it is precisely to promote agricultural machinery to really enter the field.
Young people bring new technologies
In the mechanization of agriculture, drones have increasingly become a new force that cannot be ignored.
In Hainan planted mangoes for 15 years, now managing 8,000 acres of mango orchards Zheng Mianpeng, when the purchase of machinery is also a try mentality, after all, in the busy agricultural season, orchards are difficult to hire labor, at the beginning, he only used drones in part of the orchard for management, did not expect that a year, drones helped him save 600,000 yuan. What is even more surprising is that when the year-end accounting is settled, he also found that the drone can save pesticides.
Zheng Mianpeng carefully analyzed and found that when the drone sprayed pesticides, although the concentration of the liquid was high, it could only be sprayed in the canopy area, avoiding pesticide waste. The branch-to-target technology and large wind field carried by the UAV can make the pesticide adhere well to the leaves, and improve the utilization rate of the pesticide. So he began a drone pesticide reduction experiment on a mango orchard.
DJI also organized a team of engineers to support him, optimizing the route, changing the sprinkler head, testing the amount of mu used, and finding the optimal spray parameters. After half a year of exploration. At relative limits, mango orchards can achieve pesticide savings of up to 50 percent and as low as more than 30 percent.
A mango tree can reduce the pesticide by 30% to reduce the input by 21 yuan, and the mu of land can be reduced by 900 yuan. If Sanya's 400,000 acres of mango orchards can apply this new technology, it will bring 360 million yuan of income to fruit farmers. If you take into account the environmental impact of pesticide reductions, the value of this technology will be even more substantial.
Mangoes are grown in this way, so can other varieties also play the role of drones? The answer is yes.
In the Guangxi Wo Orange and Gannan Navel Orange projects, DJI engineers have found a breakthrough. In Ganzhou, there are more than 200,000 navel orange growers, and before that, Liu Senliang of Ningdu County managed 350 acres of orchards, before that, his father was hiring long-term workers, and it took 10 people 12 days to complete a single medicine, and paid 15,000 yuan or even higher for labor wages.
Now, drones coupled with a small number of manual management can not only reduce costs, improve efficiency, but also ensure the health of orchards.
In the agricultural provinces with high popularity of flight prevention, more and more farmers have become the main force of purchase. They buy drones to do their own homework while helping their neighbors.
According to the data of Huifei College's "2020 Plant Protection UAV Industry Development Report", in 2020, the cumulative sales volume of domestic agricultural UAVs has reached 60,000 units, the number of ownership has reached 110,000 units, and the operating area has exceeded 1 billion mu. The data will continue to grow at a high rate in 2021.
It's not just spraying fertilization
At present, drones have played a role in many areas of people's production and life: in the night sky, it accurately arrays and incarnates as "colorful elves"; in the fields and mountains, it sprays pesticides and transforms into "guardian angels"; in the bustling streets, it directs dispatch and becomes the "eye of the air"...
The industry's cognition of DJI was first considered to be a "aerial photography, toy", or consumer drone. In fact, as early as 2015, DJI began to get involved in various industries, including agriculture, security, surveying and mapping, energy, and construction.
From plant protection to allow farmers to be exposed to pesticides as little as possible, DJI has gone deeper into more scenarios. For example, through aerial surveying, after the completion of farmland mapping, and then analyzed with the AI system, the boundaries of farmland can be identified, and different categories of farmland, such as farmland, trees, ponds, buildings, obstacles, and so on.
The multispectral sensor on the drone can collect the spectrum, generate vegetation index information, and then analyze it with an AI system. Because these crops are growing, they will have an impact on the growth status of crops due to different effects of the growth cycle, crop type and soil water source. These have become within the "capability range" of the drone.
At the beginning, DJI mainly attacked relatively flat farmland, rice fields, wheat fields, and then gradually "go up the mountain", towards fruit trees, oil palm trees, tea gardens and other high-value crops, such as oil palm trees are easily troubled by rhino beetles, spraying must be in the center of the tree to kill the beetles, so through AI technology, the tree core is recognized and then accurately sprayed, more penetrating.
In the vast countryside, there are more and more scenes that require drones, and the inspection of electric towers, communication towers, roads, railways, bridges, tunnels, etc., has also been gradually broken.
DJI began with drones, but it has greatly expanded the functions of drones, and become a flight platform for drones, carrying different software through hardware loads, can flexibly respond to various scenarios, face different industries, different fields, realize personalized customization needs, and have end-to-end complete solutions.
On the one hand, compared with ground machinery, agricultural UAVs have the advantages of high efficiency and strong terrain adaptability, which can effectively fill the shortcomings and gaps in the application of traditional ground agricultural machinery, and are of great significance to improving the weak links of Agriculture and the mechanization of weak areas in China.
On the other hand, more importantly, compared with ground machinery, the better intelligent software and hardware system of unmanned aerial vehicles is also an important support for China's future continuous promotion of digital agriculture.
Push the boundaries of imagination
Going deep into the front line, starting from the user value, breaking through one scene after another has become an important driving force driving DJI to deeply cultivate the field.
On November 15, DJI's two new agricultural drones, the T40 and T20P, were officially released. These two products use a new fuselage platform, and for fertilizer sowing, fruit tree spraying and other application scenarios have been optimized, to T40 as an example, compared with the previous generation of load increased by 33%, can be equipped with 40 kg spray box or 50 kg spread box, can make the fruit tree leaves back of the liquid adhesion rate increased by 2 times.
The effective spraying amplitude of T40 can reach 11 meters, and the measured field efficiency can reach 320 mu per hour, which is 30% higher than that of the previous generation. Its emergence has once again raised the efficiency, effect, intelligence and safety of agricultural drones to a new height.
DJI has been pushing the boundaries of imagination and continuing to innovate in various fields. How to liberate producers from complicated farmland management, how to reduce the cost and threshold of tools, etc., T40 and T20P are born in a series of "truth" inquiries.
Their breakthroughs in the four dimensions of operational efficiency, intelligent safety, application scenarios and reliability will help global agricultural producers manage crops more efficiently. They carry DJI's new vision of the agricultural track.
New equipment and new technologies make young people more willing to return to the countryside. In fact, Shen Xiaofen is not alone, in Shihu Village, five "post-90s" including Shen Xiaofen returned to the countryside without hesitation. This is just a microcosm of the "new farmers" returning to their hometowns to start a business.
Returning home to start a business has become a new choice. According to data from the Ministry of Agriculture and Rural Affairs, the cumulative number of entrepreneurial and innovative personnel returning to their hometowns in 2020 reached 10.1 million, an increase of 1.6 million over the previous year, an increase of 19%.
"It is necessary to promote the revitalization of rural talents, put the development of human capital in the first place, and strengthen the support of rural revitalization talents." The "Opinions on Accelerating the Revitalization of Rural Talents" issued by the CPC Central Committee and the State Council put forward that "vigorously cultivate local talents, guide urban talents to go to the countryside, promote professional talents to serve the countryside, and attract all kinds of talents to make contributions in rural revitalization."
In the future, the application expansion of DJI agriculture will form three echelons. The first echelon is the Field Application. The second echelon is fruit tree applications. The third echelon is to promote the application of digital agriculture to reduce weight loss and reduce drugs, increase production and income.
DJI Agriculture will also continue to promote young people to return to their hometowns to start businesses, participate in the revitalization of the country's rural areas, participate in the popularization of agricultural mechanization, participate in the innovation of agricultural industry, and work with DJI Agriculture to promote the sustainable development of China's agriculture and realize the beautiful vision of "making agriculture easier and life better".
