Design and Experiment of a Precision Seeding Implement for Morchella esculenta

To address the technical challenges in the artificial sowing of Morchella esculenta, such as high labor intensity, poor seeding uniformity, and easy accumulation of spawn, a lightweight precision seeding machine based on electric control technology was designed. This mechanical device adopts a double-layer structure, with its core components comprising a stirring mechanism, a metering device, a sprocket transmission system, and a traveling mechanism. Through the coordinated action of a two-stage stirring device （a primary stirring barrel and a secondary stirring disc）, it effectively overcomes issues like spawn adhesion, blockage, and uneven seeding under high humidity conditions （60%−65%）. Field test results indicate that the machine performed well overall at operating speed was 20 m/min. The seeding uniformity error was less than 10%, no blockage occurred, and the seeding rate remains stable at 1.0 ± 0.1 kg/m²; under the fully open state of the discharge port. All performance metrics met the agronomic requirements for precision sowing of Morchella esculenta. This machine significantly reduces manual labor intensity and improves operational efficiency by more than five times compared to traditional manual sowing methods, providing an efficient and reliable mechanized solution for the large-scale cultivation of Morchella esculenta.
