**Cd-covered car sowing:** Before emergence is essential, it is considered that covering the seedbed improves seed germination. By using this method, seeds can expand within two days, with germination rates reaching over 98%. Additionally, the timing of emergence becomes more centralized, leading to more uniform seedling growth and better commitment to healthy plants.
Furthermore, increasing the regulation of surface temperature can promote hot, rigid bud dynamics. **Covering material:** Straw is the best option.
**Method of operation:** First, use straw to cover the remnants of grain in the field. Spread the straw evenly, with a thickness of approximately 1-1.5 centimeters after sowing. Ensure that the seeds are covered uniformly and that water leaching through the straw allows for maximum absorption by the seeds. The straw helps stabilize external temperature changes. Typically, seeds will germinate within 8-10 days under these conditions. If transplanting seedlings, the straw should be removed just before emergence to avoid delaying the growth process. Removing the straw too early may weaken the seedlings, while removing it too late can hinder emergence persistence and plant growth. Properly timed removal of the straw ensures strong, robust seedlings with higher survival rates.
