Since 1998, Shandong Liangyi Farm has been using the 2BQM-6A corn no-tillage precision seeder to adopt and promote new techniques in no-tillage machinery. Over the years, we have accumulated practical experience that we would like to share below.
Firstly, to ensure even seed distribution and consistent spacing for easier field management later on, we developed a custom marking system. We place marker poles across the field to guide the machine and maintain straight rows during sowing.
Secondly, we noticed that foreign objects on the seed trays can cause the cylinder seedlings to be cut off, which affects the suction process and may lead to unexpected machine stoppages. Therefore, it is essential for operators to constantly monitor the seedlings and quickly address any issues. If there are missing seeds, they should be replanted immediately to avoid yield loss.
Thirdly, when starting the machine, if the throttle is too low or the rotation speed is insufficient, the negative pressure may not be enough to suck the seeds properly. To prevent this, the throttle should be increased at the beginning of the operation.
Fourthly, the problem of sparse seedlings and low yields occurs annually. This is often due to excessive plant spacing. Adjustments can be made by increasing the number of seed holes and adjusting the sprocket ratio. Another reason could be a low germination rate or insufficient seeding volume. The germination rate should exceed 90%, and before sowing, seeds should be cleaned, soaked, and prepared properly. The recommended seeding rate is about 38 kg per hectare, with approximately 90,000 plants per hectare and 67,750 to 7,500 seedlings per hectare depending on the variety.
To ensure uniform seedling emergence, we follow a specific process tailored to our field conditions: first, a combine harvester cuts the wheat straw and returns it to the field. Then, we perform no-tillage sowing, use a straw returning machine to crush the stubble, apply herbicides, and conduct sprinkler irrigation. It's worth noting that chopped wheat stalks can be returned to the soil, offering multiple benefits—covering the soil surface, suppressing weed growth, keeping the soil loose, and improving drought resistance.
Lastly, common faults observed in this model include: one row of seed disks failing to pick up seeds, usually due to low rotation speed or blockage from debris. Second, the intermediate shaft breaking, often caused by a tight belt. Third, the knife not being properly buried or broken, which results from wear or looseness. Fourth, disc openers not rotating, typically due to poor bearing conditions, which require inspection, lubrication, or adjustment.
By continuously refining our practices and addressing these challenges, we aim to improve efficiency and crop yield in our no-tillage farming operations.
