Abstract: Nursery trays are essential agricultural tools in rice production. Plastic nursery trays pose problems such as resource waste and environmental pollution. Biomass seedling trays are an effective way to achieve sustainable agricultural development. Previous research has been conducted on biomass seedling tray molding equipment and molding process, but the impact of raw material ratio on seedling tray molding quality and seedling growth is still unclear, and the ratio combination still needs further optimization. In this study, we used slurry concentration, pulp content, adhesive content, and the ratio of straw to cow manure as variables. We selected the bowl hole molding rate and the strong seedling index as evaluation indicators, and carried out biomass seedling tray forming experiments and seedling cultivation experiments. The response surface analysis method was used to optimize the raw material ratio of biomass seedling trays from the perspectives of forming effect and seedling quality. The results show that when the slurry concentration is 30%, the pulp content is 20%, the adhesive content is 530 g, and the mass ratio of straw to cow manure is 2:1; the bowl hole molding rate is 91.03%, and the strong seedling index is 0.22, indicating good molding effect and seedling growth. The verification test results indicate that the theoretical analysis results are accurate, and the model fitting is good. These research results provide a theoretical basis for the preparation of biomass seedling trays and technical support for achieving green development in agriculture.
