In a no-till field, hoppers 26, 26 are separately charged with seeded rice seeds coated with an oxygen generating agent (calper) and granular fertilizers coated with a hard solvent to make them slow-acting. When the machine body is moved forward while rotating in the reverse direction so that the forming claw 14 rotates upward at the front, the forming claw 14 raises the seeding groove having a narrow width (for example, 3 to 5 cm) by 3 cm while scraping it up at the front. The cultivated soil excavated at the inner and outer depths and thrown up is thrown rearward through the upper part while being guided by the rotary cover 15, and the groove forming plate 24 is 1 to
The bottom surface is formed in an inverted V-shape by advancing in a state of entering into the groove at a position 2 cm away.

The cultivated soil that has been separately thrown into the left and right depressions at the bottom of the sowing groove through the insides of the pits 8, 28 collides with the rake 18 to collide with the rake 18 and is further crushed and sieved to separate fine cultivated soil. The large-diameter cultivated soil, straw or weeds, etc., which are covered with seed rice and granular fertilizer, slide down on the rake 18 and flow obliquely backward along the sieve rods 20. At this time, since the sieve rods 20 are inclined backward, the rake 18
Cultivated soil that has been thrown onto it by throwing large-diameter lumps, weeds, etc., to be deposited on it. The covering soil should be 1cm or less in particle size.
In a state in which 0% or more is contained, a thickness of 0.5 cm causes drying damage, and a thickness of 2 cm or more causes poor germination due to lack of oxygen.
It is desirable to set it to 2 cm.

Also, even if the heights of the lower ends of the seed conduit 28 and the fertilizer conduit 28 are shifted up and down, the separation of the fertilizer and the seeds is improved, and the burning of the fertilizer immediately after germination can be prevented. In any case, it is desirable that the interval between the seed rice and the granular fertilizer is 2-3 cm. Then, when water is supplied to the field at the time of germination 7 to 10 days after sowing, the growth is improved.
