Our Story

In the Chinese countryside of 2000, a pivotal transition was underway from traditional to modern agriculture. In the old premises of an agricultural machinery repair shop in the heart of the Huang-Huai-Hai Plain, seven young individuals, with an average age of less than 35, crafted the core components of the first sprayer using borrowed machine tools. Little did anyone anticipate that this small workshop, born at the turn of the century, would grow into a leading plant protection equipment enterprise serving over 5 million farmers across 30 provinces in China twenty-four years later. From hand-forged metal parts to intelligent aerial defense systems, from gathering on-the-ground pain points to setting industry standards, the factory's development history mirrors the microcosm of China's agricultural modernization drive.

In the spring of 2000, Wang Guang, the chief engineer who had just resigned from the Agricultural Machinery Research Institute, rented three old workshops in Dezhou, Shandong, with six colleagues. At that time, China's plant protection equipment market showed a polarized landscape: imported equipment was prohibitively expensive, costing over 80 yuan per mu (a Chinese unit of area, approximately 0.0667 hectares); domestic equipment was crude and rough, with frequent药液 leakage and uneven spraying. During a research trip in the wheat-growing regions of northern Anhui, the team was deeply moved by an elderly farmer bending under the weight of a pesticide sprayer—his back curved by the 20-kilogram chemical bucket, a towel around his neck soaked with sweat, yet less than half of the pesticide actually adhered to the crops.

"First, let's reduce the burden on farmers" became the team's initial goal. They converted their dormitory into a laboratory, visiting farmlands during the day with blueprints marked with countless revisions, and discussing structural improvements around kerosene lamps at night. To address the issue of traditional sprayer straps pressing on the spine, the team drew inspiration from the pressure-relief principle of mountaineering backpacks, designing an S-shaped back frame with buffer devices. To solve the problem of drug liquid residue, they tested over ten types of sealing materials, ultimately selecting nitrile rubber for its strong corrosion resistance. During the autumn harvest of 2002, when the first generation of "30% weight-reduced" backpack sprayers were tested in the cornfields of Xinxiang, Henan, 70-year-old Farmer Zhang walked two miles with the machine on his back and exclaimed in surprise, "This thing feels like an empty bucket!"

Word of mouth spread quietly among farmers. In 2003, this sprayer, priced at only one-third of imported products, achieved sales of 50,000 units, capturing 17% of the market share in the Huang-Huai-Hai Plain. However, a true turning point came in 2004—when the team witnessed in the cotton fields of Xinjiang Production and Construction Corps that a plot requiring 20 people to spray manually in one day could be completed by a single person in just 2 hours using their newly developed tractor-mounted spray boom equipment. This "eye-opening experience" made the team realize that minor improvements were insufficient; a fundamental transformation of plant protection operations was necessary.

In 2005, the factory relocated to a newly built standardized factory area, with its first automated production line put into operation. That winter, the R&D team took the newly produced self-propelled sprayers to conduct low-temperature tests in the snowfields of Heilongjiang Agricultural Reclamation Bureau. When the machines operated continuously for 8 hours without failure in -15℃ conditions, the agricultural technicians present sighed, "You've advanced spring plowing in Northeast China by half a month."

In 2008, the revised "Pesticide Administration Regulations" explicitly proposed requirements to "improve pesticide utilization efficiency and reduce environmental pollution." By this time, the factory already had the capacity to produce 100,000 units of various plant protection equipment annually. However, an environmental survey in the Taihu Lake basin of Jiangsu Province gave the management pause—local farmers reported that traditional sprayers had severe "leakage issues," not only wasting pesticides but also causing fish deaths in surrounding fish ponds.

"We must not only calculate economic accounts but also ecological ones," said the chairman at a company-wide meeting, marking the beginning of the enterprise's transformation. The R&D team spent three years tackling "precision atomization" technology, conducting thousands of experiments to control the atomized particle size within the optimal range of 150-200 microns—ensuring effective adhesion while preventing drift due to excessively fine particles. The "Green Shield Series" sprayers launched in 2010 increased pesticide utilization rate from 35% (with traditional equipment) to 72%, earning the "Green Product Certification" from the Ministry of Environmental Protection that same year.

During the promotion in Xinjiang's cotton-growing areas, a widely told story emerged: a Kazakh cotton farmer initially refused to use the new equipment, believing that "the stronger the spray, the better the effect." Instead of pushing sales, the technicians line out two experimental plots in his field. By harvest time, the plot using the new equipment not only reduced pesticide usage by 40% but also increased yield by 15 kilograms per mu. This once-stubborn old man ultimately purchased three units and even volunteered as a product promoter.

In 2013, the factory established the industry's first "Plant Protection Equipment Environmental Impact Laboratory," setting enterprise standards across six dimensions including pesticide residue, energy consumption indicators, and noise pollution. These standards were later referenced in formulating national industry standards. In the same year, a "Smart Plant Protection Joint Laboratory" was established in collaboration with China Agricultural University, integrating sensor technology into traditional equipment. At a wheat base in Xuchang, Henan, the first batch of sprayers equipped with flow sensors could automatically adjust pesticide dosage based on crop density, reducing pesticide usage by 28% per mu and transforming "pesticide application based on experience" into precise data-driven practice.

In 2016, when the central government's No. 1 Document first proposed "developing smart agriculture," the factory sharply seized the trend toward intelligentization. At that time, drone-based plant protection was still in its infancy. The team boldly invested 20 million yuan in R&D, forming an interdisciplinary team consisting of aerospace engineers, agricultural technicians, and software developers. Initial experiments faced challenges—in greenhouses in Shouguang, Shandong, drones crashed into tomato fields due to signal interference; on the Inner Mongolian grasslands, strong winds caused severe deviations in spray trajectories.

Technicians immersed themselves in farmlands to address these issues: testing over 200 signal enhancement solutions in greenhouses and recording 300 sets of data on wind speed and spray angles on the grasslands. In 2018, plant protection drones equipped with a "ground-air coordinated navigation system" were launched, capable of centimeter-level positioning in complex terrains, with an operational efficiency 30 times that of manual labor. More importantly, operational data such as area covered and pesticide usage could be accessed via a mobile app, enabling "visible management." At the Jiansanjiang Farm in Heilongjiang, these drones achieved unmanned agricultural pest control in over ten thousand hectare of rice fields earning them the nickname "flying agricultural technicians" among farmers.

During this period, the enterprise completed its transformation from a single equipment manufacturer to an integrated "equipment + services" provider. The "Nongweishi" (Farm Guardian) service platform launched in 2019 integrated functions such as plant protection equipment scheduling, technical training, and agricultural supplies provision, providing one-stop solutions to 200,000 farmers. In Yunnan's Pu'er tea regions, the platform recommended plant protection schemes based on varying altitudes and soil pH levels, reducing pest and disease incidence in ancient tea trees by 60% and increasing income by over 3,000 yuan per mu.

During the COVID-19 pandemic in 2020, the factory demonstrated strong social responsibility. When regions like Hubei and Shandong faced shortages of agricultural machinery operators and disruptions to spring plant protection, the enterprise urgently formed an "Anti-epidemic and Spring Plowing Commando," deploying 200 units of intelligent plant protection equipment and 50 technical service teams to assist. In vegetable bases around Wuhan, technicians operated drones while wearing protective suits, ensuring timely pest control for 50,000 mu of "vegetable basket" bases. During this special period, the enterprise not only provided services free of charge but also donated disinfection equipment worth 5 million yuan, earning recognition as an "Advanced Collective in National Agricultural Disaster Resistance and Relief" by the Ministry of Agriculture and Rural Affairs.

Entering a new stage of development, the factory has set its sights on broader horizons. In 2021, the 120 million yuan "Future Plant Protection Research Institute" was put into operation, focusing on cutting-edge technologies such as low-carbon environmental protection and artificial intelligence. Currently, it has successfully integrated solar power into plant protection equipment, extending the battery life of electric sprayers to 8 hours. The developed "AI Crop Health Monitoring System" can predict pest and disease outbreaks 7 days in advance through image recognition, with an accuracy rate of 92%.

Guided by the rural revitalization strategy, the enterprise has deepened cooperation with remote areas. In Kashgar, Xinjiang, it established the largest plant protection equipment maintenance service center in southern Xinjiang, training 120 Uyghur technical backbones. In the Daliang Mountains of Sichuan, it launched the "Plant Protection Technology Poverty Alleviation Initiative," providing free equipment and training to Yi farmers, helping over 5,000 formerly impoverished households develop characteristic farming. These initiatives have enabled advanced technologies to cross mountains and rivers, benefiting farmers in more remote corners.

Over twenty-four years, the enterprise's product range has expanded from a single type of sprayer to 6 major series and over 80 varieties, including ground machinery, aerial equipment, and intelligent systems. It has produced over 8 million units of various plant protection equipment, reducing pesticide waste by 180,000 tons—equivalent to protecting the ecological safety of 6 million mu of cultivated land. From a 500-square-meter old workshop to a 120-mu modern industrial park, from a 7-person startup team to a 1,200-employee enterprise group, what has changed is scale and technology, while what remains unchanged is the original aspiration of "letting every inch of land receive meticulous care."

Today, in the factory's product exhibition hall, the first handcrafted sprayer stands in silent dialogue with the latest intelligent drone across time, witnessing the growth of an enterprise and reflecting the changes in Chinese agriculture. Looking to the future, the enterprise is advancing steadily on the path of digital agriculture and low-carbon development, with the vision of "building a green plant protection ecosystem." As the chairman stated at the 20th-anniversary celebration, "Our roots will always be in the fields, and our mission will always be to safeguard the vitality and hope of the land."

From a single rivet at the turn of the century to a technological force safeguarding hundreds of millions of mu of fertile farmland today, the story of this plant protection equipment factory continues to unfold. On the journey of agricultural modernization, it is not only a participant and witness but also a guardian that grows in harmony with the land forever.
