How to store cotton seeds?
Cotton seed storage involves several key technical considerations to ensure quality and longevity. First, it's essential to harvest the cotton seeds before frost sets in, when the embryos are fully developed, and the seed shells are hard and resistant to damage during storage. This ensures that the seeds are mature and less prone to spoilage.
Second, cotton seeds have a natural tendency to absorb moisture, so after sun-drying, they should be properly sealed to prevent humidity from affecting their quality. Proper drying and sealing are crucial steps in maintaining seed viability.
Third, imported cotton seeds must meet specific quality standards. The moisture content should not exceed 11-12%, impurities must be below 0.5%, and the germination rate should be at least 90%. Additionally, the seeds should be free from mold, pests, diseases, and damaged kernels to ensure successful planting.
Fourth, proper storage conditions are vital. When placing seeds in storage, it's recommended to fill the containers to about half their capacity to allow for good air circulation and easier monitoring. The temperature should be kept below 15°C, and regular checks should be conducted to ensure stability.
Lastly, safety measures such as fire prevention and rodent control are essential. Storing seeds in a clean, dry, and secure environment helps protect them from external threats. By following these guidelines, farmers and storage facilities can maintain high-quality cotton seeds for future use.
