1. Selection of Seed Coating Agents
To ensure effective seed coating, suitable agents were carefully selected through community trials and field demonstrations conducted in the region. These trials helped identify the most appropriate options that align with local growing conditions and crop requirements.2. Seed Quality Standards Before Coating
Before applying any coating agent, the seeds must meet strict quality standards. These include a species purity of at least 99%, seed purity of no less than 95%, clarity of over 99%, moisture content below 12%, germination rate exceeding 80%, residual acid content not exceeding 0.15%, and a breakage rate under 7%. These standards are essential to guarantee the effectiveness of the coating process and the performance of the treated seeds.3. Seed Coating Methods
The coating process should strictly follow the manufacturer's instructions for each type of seed coating agent. For example, some agents do not contain insecticides, such as 26% more than foxrocide, which may not provide sufficient protection against cotton seedling pests. In such cases, an alternative approach is recommended: first coat the seeds with phosphorus-based material at a ratio of 0.8:100, then let them sit for a while before drying and applying the 26% Duofu Jiamu coating. After drying, the seeds can be bagged for broadcasting. Another method involves mixing phorate and dofloxacin in a ratio of 0.3 to 0.4:1, then applying the mixture directly to the seeds. After drying, they can be bagged for sowing. If a seed coating dryer is available, the seeds can be directly bagged without additional drying steps.4. Quality Testing of Coated Seeds
Prior to coating, it is crucial to test the germination rate, moisture content, residual acid level, and breakage rate of the seeds to ensure they meet national seed quality standards. Only seeds that pass these tests should be used for coating. During the coating process, moisture levels must be monitored regularly. If the moisture exceeds the allowed limit, immediate drying is required until the level drops to 12% or below. Additionally, germination tests should be conducted on each batch of coated seeds to maintain quality. The coverage and adhesion of the coating must also be inspected thoroughly to ensure the final product meets all quality specifications for coated seeds.By following these detailed procedures, farmers can significantly improve the performance and success rate of their cotton crops, ensuring better growth and higher yields.
Polylactic acid (PLA) is a novel biodegradable material made from starch derived from renewable plant resources such as corn. Starch raw materials obtained glucose through saccharification, and then fermentation of glucose and certain strains to produce high purity lactic acid, and then through chemical synthesis method to synthesize polylactic acid of a certain molecular weight. It has good biodegradability and can be completely degraded by microorganisms in nature after use, resulting in carbon dioxide and water, which does not pollute the environment. It is very beneficial to environmental protection and is recognized as an environmentally friendly material. Ordinary plastics are still incinerated, causing a large amount of greenhouse gases into the air, while polylactic acid plastics are buried in the soil to degrade, resulting in carbon dioxide directly into the soil organic matter or absorbed by plants, will not be discharged into the air, will not cause the greenhouse effect.
