The rice combine harvester has high requirements on bed soil thickness, seedling height, seedling packing and sowing uniformity. Uniform sowing and high-quality machine-transplanted seedlings can be lifted with one hand without scattering seedlings or soil.
Suggestion: In areas where the use of rice transplanters is popularized, especially in areas where seedlings are raised for the first time, it is recommended to start using rice transplanters starting with walk-behind or trailer-mounted rice transplanters, which can artificially reduce seedlings and field non-standard Effects of rice transplanting.
2. Field conditions
1. The non-continuous seedling distance of the field
In the machine transplanting operation, the number of self-contained seedlings is affected by the load and loading space of the machine, and the planting distance is basically about 100 meters. At this time, the field head needs to be shut down to prepare seedlings. Ensuring a certain straight-line transplanting distance is the key to improving operation efficiency. The ideal distance is about 200 meters. If the ridge distance is too long, it will not be possible to continue seedlings in the middle, which will inevitably cause too many seedlings for the transplanter, overloading the machine, serious body subsidence, and even failure to work.
Suggestion: If the field is too large, the rice transplanter may be overloaded with seedling preparation. It is necessary to adjust the distance of the field for seedling loading, and at the same time, it is necessary to choose a high-power model.
2. Deep plowing of fields
The ride-on rice transplanter has higher requirements on the depth of the mud foot in the seedling field. Although rice transplanters are all four-wheel drive devices, once the depth of the mud feet exceeds the radius of the front wheels, it will be difficult for the machine to complete the climb and cannot guarantee normal operation.
Suggestion: The high-speed rice transplanter is limited by the depth of the mud foot. When plowing the land at the initial stage, this requirement should be considered. Once the mud foot depth exceeds the standard, only the walk-behind rice transplanter or the floating boat type (trailer type) can be used.
3. Soil viscosity
The power consumption of the rice transplanter is affected by the soil quality to a certain extent.
Suggestion: In seedling fields with high soil viscosity, when using a ride-on rice transplanter, it is necessary to consider using a higher-power mechanical engine.
4. Reasonable configuration of the balance device of the seedling planting platform
The quality of transplanting is reflected in the depth of transplanting to a certain extent, and stable shallow planting is the guarantee of transplanting quality.
Suggestion: Among the three balancing devices, choose and configure reasonably according to the land where the machine is purchased, and the conditions of the mud base and mud surface after spinning the field.
3. Basic Seedling Requirements
There is a big difference in the amount of seedlings taken by rice transplanters. At present, the row spacing of high-speed ride-on rice transplanters on the market is mostly 30 cm, the plant spacing is 12-28 cm, and the basic seedlings are 120,000-315,000 holes/ha.
