Rice transplanters were invented in Japan in the 1960s. This machine was introduced in Pakistan a few years ago. Mechanical rice transplantation is gaining popularity in Pakistan with time.
Rice Transplanter is an automated machine for rice nursery transplantation into paddy fields. Rice transplanters are classified into two categories.
The riding type is derived by the driver sitting on it and transplants six lines in one pass. While the walking type is manually driven and is further of two types
- 4-Line Transplanter
- 6-Line Transplanter
Mechanical Rice Transplantation consists of two machines,
- Seeding Machine
- Seedling Transplanter
The rice seed is given by the farmer to the Transplanter operator, who subsequently sows the rice seeds into the plastic trays. The sowing machine contains three compartments: the first is loaded with soil, the second with rice seeds, and the third and final compartment is filled with soil once more. The soil used in this seeding equipment has been thoroughly sieved to remove any unwanted debris such as pebbles.
Firstly, soils are placed into the trays followed by the rice seeds then another layer of the soil is placed over the seeds to cover them. Then these trays are watered lightly to promote germination.
Rice Seedling Transplanter:
Rice Transplanter is made up of the following components:
- A shed in which the seedling trays are stored.
- A seedling tray mover that moves the trays.
- Pickup forks that take up seedlings from trays and then transplant them onto the paddy field all at once.
After the seeds are sown in the trays, the seedlings are ready to be transplanted onto the paddy field after 20-25 days. One hundred seedling trays are sufficient for one acre, which typically forms 105000 hills and up to two hundred thousand rice plants.
The 4-Line Transplanter can transplant seedlings at a rate of 7-8 acres per day, while the 6-Line Transplanter can transplant seedlings at a rate of 13-14 acres per day.
Rice Transplanter Benefits:
- The fundamental advantage of this strategy is the large number of plants in the field, which results in a high yield of rice.
- Transplant shock is less severe.
- The transplanter uses less fuel, approximately 2 liters per acre.
- Uses a low water level.
- Less time and labour are necessary; one man is sufficient for one acre.
- Mechanical rice transplantation has a lower input cost than conventional rice transplantation.
- The rice seedling is transplanted to a better depth by the transplanter.
