SEEDING FURROW IN APPARATUS FOR DIRECT SOWING OF RICE ON FLOODED PADDY FIELD

摘要

PURPOSE:To obtain the subject seeding furrow, performing seeding at a shallow place and penetrating the seeds deep into soil after germination and capable of providing high yield by arranging a furrow constituent unit having protrusions at the back of a puddling unit, etc., in a direct rice sowing machine for flooded paddy field such as a tractor and forming the seeding furrows with the protrusions so as to drop seeds into the seeding furrows. CONSTITUTION:A furrow constituent unit 3 is arranged in a prescribed position at the back of a puddling unit 2 or a direct sowing machine of a tractor 1 and protrusions 4 are formed into a desired shape in the furrow constituent unit 3 so as to produce seeding furrows 5 with the protrusions 4. Thereby, seeds 6 can be dropped into the seeding furrows 5. The shape of the furrow constituent unit 3 is optional and the depth (h) of the seeding furrows 5 is embodied as desired to drop the seeds 6. As a result, soil cover on the top surface of the seeds 6 is shallow at the beginning so as to facilitate the germination. After the germination, the top surface of the seeds 6 is gradually covered with soil thick by waves, etc., of water to form the seeding furrows in the apparatus for direct sowing of rice on flooded paddy field so that the seeds may be resistant to tillering, growth and lodging and related with high yield.
