This invention discloses a method for producing crop cultivation substrate using sugarcane filter mud and sugarcane pith as main raw materials, comprising the following steps: (1) dissolving and diluting 4,5-dihydro-4,5-dioxo-1H-pyrrolo[2,3-f]quinoline-2,7,9-tricarboxylic acid in water to obtain a solution; (2) mixing sugarcane slurry, sugarcane pith, the 4,5-dihydro-4,5-dioxo-1H-pyrrolo[2,3-f]quinoline-2,7,9-tricarboxylic acid solution, fermentation agent, and improver, adjusting the moisture content, and then composting and fermenting. The compost is turned over every few days and continuously composted and fermented for several days to obtain the crop cultivation substrate. The crop cultivation substrate produced by this invention is of excellent quality, allowing direct planting of plants without root burn. Therefore, this invention, using sugarcane filter mud and sugarcane pith as main raw materials to prepare and produce crop cultivation substrate, can effectively solve the problem of comprehensive utilization of sugarcane filter mud and improve product sales.

This invention discloses a method for treating livestock and poultry manure through composting, which can significantly improve the seed germination index. This method effectively increases the seed germination index. After a secondary aerobic treatment in a composting tank for 5 to 10 days, the seed germination index is significantly improved. Experiments have verified that it can increase by more than 50% compared to the untreated state, meeting or even exceeding the requirements of organic fertilizer industry standards for seed germination index. The aerobic treatment method used in this invention requires no chemical reagents, utilizing only a natural aerobic fermentation process, thus avoiding the potential harm of chemical residues to the soil and environment, and aligning with the concept of green and environmentally friendly agricultural development.

This invention discloses a method for preparing functional compost, belonging to the field of agricultural waste resource utilization and grassland ecological restoration technology. The key technical points include: mixing fresh sheep manure, wheat straw, and corn straw at a specific wet weight ratio and adding superphosphate to obtain a basic mixture; inoculating this mixture with a compound microbial fermentation agent composed of *Bacillus steatophilus*, *Bacillus subtilis*, and *Bacillus mucilaginosus* at a specific viable count ratio to obtain an inoculum; subjecting the inoculum to aerobic composting fermentation and implementing dynamic turning control based on dual temperature thresholds to maintain the compost within a specific high-temperature range for a sufficient number of days; and finally, aging the material until its seed germination index reaches a specific range to obtain functional compost. The functional compost prepared by this method is mainly used for restoring degraded grazing grasslands.

This invention discloses a dry heat treatment method for tomato seeds to enhance seed vigor and extend storage life, relating to the field of tomato seed storage technology. The method includes: selecting mature, plump, and undamaged commercial tomato seeds with consistent maturity and maintaining appropriate moisture content; placing the pre-treated seeds in a single layer on a tray and placing it in a dry heat treatment device, performing dry heat treatment sequentially according to a preset program; comparing the germination indicators of dry heat-treated and untreated seeds to determine the effect of the dry heat treatment; and sealing and storing tomato seeds with qualified germination rates. This invention, through precisely controlled stepwise heating and high-temperature constant-temperature sterilization, effectively activates the seed's internal repair enzyme system while inhibiting metabolic processes that lead to seed deterioration, avoiding physical or physiological damage to the seeds caused by high-temperature treatment, and effectively preventing seed coat cracking, radicle burn, or excessive dehydration.
