Description

Technical Field

[0001] This invention relates to the field of tree seed ball processing technology, specifically a method for making tree seed balls. Background Technology

[0002] Seed coating is a seed treatment technology that provides seeds with precise and appropriate amounts of nutrients and protective substances, reducing the use of chemical fertilizers and pesticides, resisting adverse factors, promoting seed germination, and modifying the physical structure and size of seeds to facilitate mechanized sowing. It is an important engineering technology for sustainable agricultural development. In ecological restoration work, ecological restoration of challenging sites is difficult, with low plant survival rates and low seed germination rates. How to comprehensively utilize solid waste generated from agriculture and forestry to improve the planting and sowing environment and enhance seed germination rates is a task worthy of continuous exploration and innovation. Summary of the Invention

[0003] In view of the problems existing in the prior art, the present invention discloses a method for making tree seed balls, comprising the following steps: Step 1: Collect agricultural and forestry solid waste materials by category, and ferment them through aerobic composting. Control the moisture content to 50-60%, the carbon-nitrogen ratio to 25-30:1, turn the pile regularly to ensure oxygen content, control the temperature to 55-65℃, and ferment until the solid waste materials are dark brown or black, loose in texture, and without foul odor. Fermentation is then complete, and fermented solid waste materials are obtained. Step 2: Crush the fermented solid waste material using a crushing device and then sieve it to obtain solid waste powder; Step 3: Prepare the material by weight ratio of 80-85% solid waste powder, 14.9-19.9% ​​clay, 0.1% binder, and 0.02% microbial agent. Mix the solid waste powder, clay, and microbial agent initially and evenly to obtain a dry-mixed material. Step 4: Add the binder to water to prepare an aqueous solution, and then spray the aqueous solution into the dry mixture while stirring to adjust the moisture content to 30%-50%, until it can be formed into a ball by hand without dripping water, thus obtaining the mixture. Step 5: Put the mixture into the refining equipment, control the temperature and humidity, stir and knead, extrude and shape into rods, and let the rods stand for 5-10 days to obtain the coating matrix material. Step 6: Process the coating matrix material into uniform particles using a pelletizing machine to obtain the coating embryo. Combine the target plant seeds with the coating embryo one by one, and roll them to coat them, so that the seeds are coated in the coating embryo to form uniformly sized pre-made tree seed balls. Step 7: Dry the pre-made tree seed balls at low temperature using a drying device to ensure that all pre-made tree seed balls are dried to a uniform degree. Step 8: Cool the dried pre-made tree seed balls to room temperature and pack them in a moisture-proof and breathable bag to obtain the tree seed balls.

[0004] As a preferred embodiment of the present invention, the agricultural and forestry solid waste mentioned in step one includes straw, sawdust, fruit shells, pruned branches and leaves, edible fungus residue, and livestock and poultry manure.

[0005] As a preferred embodiment of the present invention, the sieve used in step two is a 20-60 mesh sieve.

[0006] As a preferred embodiment of the present invention, the adhesive in step three is sodium methyl cellulose (CMC), sodium alginate, starch gum, xanthan gum, bio-gum, etc.

[0007] As a preferred embodiment of the present invention, the microbial agent in step three is nitrogen-fixing bacteria, phosphorus- and potassium-solubilizing bacteria, rhizobia, arbuscular mycorrhizal fungi, stress-resistant and growth-promoting bacteria, etc.

[0009] As a preferred embodiment of the present invention, the temperature of the low-temperature drying process in step seven is controlled at 30-45°C.

[0010] The beneficial effects of this invention are as follows: This invention primarily addresses the challenges of ecological restoration in challenging environments. It involves collecting and processing agricultural and forestry solid waste materials such as straw, sawdust, fruit shells, pruned branches and leaves, edible mushroom residue, and livestock manure. After crushing and fermentation, these materials are mixed with clay, binders, and microbial agents to create a seed coating substrate. This substrate coats the seeds of plants to be planted, transforming solid waste into valuable ecological restoration materials. This achieves resource recycling, provides physical protection for seed germination and seedling growth, reduces risks such as wind erosion and animal predation, provides nutrients, and acts as a moisture and heat retainer. Furthermore, it allows agricultural and forestry solid waste to return to nature, helping to improve soil structure, increase organic matter content, and enhance water and fertilizer retention capacity. This facilitates efficient, economical, and sustainable ecological restoration projects in challenging environments, demonstrating promising development and promotion prospects.
