S500Pro Robots Enable Precision Spraying, Overcome Labor Shortages & Weather Challenges in 1200-Acre Fruit Base
(Suqian, Jiangsu Province) A 1200-acre fruit and vegetable base in Suyang, Jiangsu, is undergoing a technological transformation. Gone are the days when General Manager Zhou mobilized dozens of workers in a race against storms to spray peach trees before rain hit – a process fraught with hiring and scheduling pressures.
This year, Lanjiang Tech’s S500Pro orchard robots took over. Simply by planning routes on a smart terminal and uploading them to the cloud, the robots now perform autonomous navigation and one-touch operation, enabling precise, whole-orchard crop protection.
“Before, we relied on massive manual labor to beat the weather. Now, we rely on technology. The efficiency is significantly higher!” remarked Mr. Zhou.
The Three Major Challenges of Traditional Orchard Protection
- The Double Siege: Pests/Diseases & Extreme Weather
Orchards here grow yellow peaches and flat peaches, which require precisely timed spraying at sensitive growth stages. Mr. Zhou once faced reduced yields after missing the window for anthracnose prevention. With extreme weather becoming more frequent, the spraying windows have shrunk, pushing traditional manual methods to their limits. - The Cost Dilemma
Last summer, Mr. Zhou hired 20 temporary workers to combat continuous rain. This spring, local professional sprayer daily wages surged. Rising comprehensive costs, coupled with worker attrition, trap traditional field management in a vicious cycle. - The Hidden Cost of Inefficient Spraying
Traditional tow-behind sprayers have critical flaws: their tanks lack adjustable wind speed and force control, leading to significant chemical waste. Manual spraying also causes misses. This lowers pesticide utilization efficiency. Residue spots on peach leaf undersides even reduce fruit purchase prices. Appearance flaws can lower the marketable fruit rate by 5%-8%, severely impacting premium-market growers.
Facing this impasse, Mr. Zhou urgently needed a breakthrough. After learning about Lanjiang Tech’s orchard robots and their high spraying efficiency and effectiveness, he swiftly decided to adopt them.
Lanjiang Tech’s Next-Gen S500Pro Multi-Function Orchard Robot: The Solution
- World’s First 5D Fusion Navigation Redefines Boundaries
Beyond peaches, Mr. Zhou also uses the robot for daily protection in extensive grapevines. The upgraded S500Pro features a world-first 5D fusion navigation system. Whether in enclosed greenhouses, deep within peach groves, or areas with signal blockage, the robot achieves fully unmanned autonomous operation. This drastically boosts work efficiency while significantly cutting labor costs. - Precision Spraying & Stepless Wind Speed Adjustment
The robot enables precise control of chemical application per acre, ensuring uniform coverage on every plant. Paired with a university-developed air-assisted atomization system, it delivers ultra-fine mist with strong penetration, evenly coating both leaf tops and undersides. This minimizes residue spots, improving fruit appearance and quality. - Efficiency Leap Through Swarm Control
Learning the robot supports multi-machine swarm operation, autonomous recharging, and resume-spraying after interruption, Mr. Zhou highly praised its efficient coordination. “Managing a thousand acres now requires just one person, slashing labor costs by roughly 80% while significantly boosting operational efficiency,” he stated. As his operation expands, he plans to deploy multiple units to further drive intelligent orchard upgrading and scalable development.
Results: Speed, Savings & Superior Quality
Once routes are planned, the autonomous orchard robot achieves fully unmanned operation. It can complete protective spraying over 150 acres in a single day. “It’s vastly faster than manual labor. One robot equals several workers. The spraying is also more precise and even, saving on input costs while drastically reducing chemical residue,” said GM Zhou.
Lanjiang Tech now offers a full range of orchard robots, widely used for crop protection in citrus, grapes, apples, lychees, and more, continuously helping orchard owners reduce costs and improve efficiency.
