Environmental Requirements for Precision Sowing

Precision sowing requires specific environmental conditions to ensure optimal crop growth and yield. First, the field should be well-prepared with fine, loose soil suitable for high-yield plots that have good access to water, nutrients, and proper soil structure. The land must be deeply plowed, thoroughly tilled, and compacted to create a uniform seedbed that promotes even germination and strong root development. Second, high-quality seeds are essential for successful wheat sowing. The selected seeds should be high-yielding, with strong tillering ability and high individual plant productivity. Before planting, the seeds should be cleaned using a long-hole sieve to remove any damaged or underdeveloped grains. This ensures that only full, viable seeds are used, which increases the germination rate. Additionally, it is recommended to treat the seeds with appropriate pesticides or fungicides to protect against pests and diseases before sowing. Third, choosing the right sowing date is crucial. Early sowing is beneficial for certain wheat varieties, as it allows for more tillers to develop, leading to higher yields. However, this should be based on local weather conditions, such as temperature and soil temperature. For winter wheat, the ideal sowing period is when the average daily temperature ranges between 15°C and 18°C. Troubleshooting Common Sowing Issues During the sowing process, several common problems may arise. One issue is missing seeds, which can be caused by a blocked seed outlet, clogged input tubes, an unengaged clutch, or weak or broken springs in the row-type reducer box. Another problem is the repressor wheel not turning smoothly or the clay scraper blade being dull or having excessive clearance. In such cases, the scraper may hit the anti-slip gear or the soil may be too moist, affecting performance. Additionally, if the drive shaft becomes misaligned during operation, the seeder may become unbalanced. This often happens when the unilateral limit chain of the tractor's suspension mechanism is too short, causing uneven pressure and poor seed placement. Safety and Operational Precautions Operators must follow strict safety procedures to prevent accidents and equipment damage. It is important not to engage the power unit before the seeder is properly positioned, and avoid suddenly lowering the seeder, as this can damage both the tractor and the seeding equipment. When reversing or turning, the machine should be stopped to maintain control and avoid collisions. Never allow anyone to stand or work on the seeder while it is in operation, as this poses a serious risk of falling or being caught in moving parts. Finally, always turn off the engine before replacing any components to ensure safe maintenance and reduce the risk of injury. By following these guidelines, farmers can improve the efficiency and success of their precision sowing operations while ensuring the safety of both operators and equipment.
