The main causes of seedling transplanting issues and the corresponding solutions are as follows:
One common problem is poor seedling posture, which may lead to floating. This can be caused by insufficient water in the seedling box or improper watering depth. If the seedlings are planted too deep in the topsoil, it's recommended to slow down the transplanting speed and press down the handlebar to ensure proper placement.
Another issue arises when the planting fork brings back seedlings without enough moisture. To fix this, the planting fork should be properly watered in the seedling box. Improper movement or deformation of the planting fork, along with gaps between the needles and the rice field, can also affect performance. Ensuring a sufficient water supply is essential for smooth operation.
Insufficient moisture in the seedling box, deformation of the box itself, wear on the needles, incorrect fork insertion, and deformation of the rubber guide plate can all contribute to problems. Additionally, issues like poor expansion and contraction, uneven paddy fields, or inconsistent water release and transplanting speed need attention.
When the number of holes in the seedling box is too large, or the seeding rate is too high, it can lead to overpopulation and weak seedlings. Absolute planting, where seedlings are not evenly distributed, can occur due to uneven density or seedling arching. Proper adjustment of the pressure device, using soil clips, and carefully handling the roots can help improve this situation.
Wear and deformation of the needles can also cause absolute planting. Inconsistent hole numbers and uneven sowing density often result from the seedling box not sliding properly. Releasing the pressure, watering the box, and guiding the roots correctly can resolve these issues.
If four rows of seedlings show uneven distribution due to water differences, the seedlings should be adjusted accordingly. Seedlings that arch on the seedling box may be caused by excessive moisture. It's important to dry the box and ensure the seedlings are properly aligned before planting.
Poor contact between the seedlings and the needles, along with improper seedling adjustment, can affect the process. A loose tightening nut on the inserting crank or misalignment of the seedling box holder can also be contributing factors.
Inconsistencies in the depth of four rows, uneven positioning of the floating plates, or a loose hydraulic valve can lead to improper seedling support. Adjustments to the hydraulic steel wire, draw rope, and insertion speed are necessary for better performance.
Slow travel speed during planting can also impact the quality of the transplanting. Ensuring the hydraulic valve is properly adjusted and the main clutch wire is secure will help maintain consistent operation.
Finally, if seedlings do not slide smoothly, check for water shortages in the seedling box. A too-wide hoe block or vertical vibration of the seedling roll around the roots can also cause problems. Addressing these issues step by step will improve the overall efficiency and success of the transplanting process.
