Design and Experiment of a Precision Seeding Implement for Morel Mushroom

To address the technical challenges in the artificial sowing of morel mushroom, 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 device 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 show that the implement performs well at an operating speed of 15 m/min, with the sowing uniformity error less than 10 % and no blockage occurring. When the feeding outlet is fully opened, the sowing rate is stably maintained at 1.0±0.1 kg/m². All performance metrics met the agronomic requirements for precision sowing of morel mushroom. This machine significantly reduces manual labor intensity and improves operational efficiency by more than five times compared with traditional manual sowing methods, providing an efficient and reliable mechanized solution for the large-scale cultivation of morel mushroom.
