Question

what are the things to do before, during, after    operation of mechanical rice transplanter ( walk behind type)

Answer 1

Mechanical transplanting of rice is the process of transplanting young rice seedlings, which have been grown in a mat nursery, using a self-propelled rice transplanter.

Things to do before:

• Apply light irrigation
• Drain off any excess water
• If weed density is high, a pre-plant application of a non-selective herbicide, such as glyphosate, should be done 24-48 hours before planting.
• Prepare the fields to a depth of 5-7 cm using a harrow or cultivator
• Puddled fields should be levelled and the soil allowed to settle for 12-24 hours
• In non-puddled conditions the soil should be tilled one to two times using a harrow or cultivator and then planked.

During planting:

• When planting, maintain a uniform depth of 1-3 cm standing water.
• The machine should be moved forward during the return pass in a manner so that the marker stays above the last transplanted row of the previous path.
• The planting clutch should be engaged While transplanting

After planting:

• Feed nursery mats onto the seedling platform.
• Leave the area equivalent to one pass of machine on all four sides of the field before starting transplanting to avoid damage to the already-transplanted seedlings while turning the machine. Start transplanting at the mark running parallel to one of the bunds.
• Keep feeding the seedling mats as needed during the transplanting operation.
• Where there are gaps, fill them manually.
• After seedling establishment, follow management practices for water, weed, nutrients and pest control as recommended for conventional transplanted rice
