DISSEMINATION METHOD OF PADDY RICE UNTILLED WELL-DRAINED PADDY FIELD V-GROOVE DIRECT SOWING CULTIVATION

摘要

To provide a dissemination method of paddy rice untilled well-drained paddy field V-groove direct sowing cultivation capable of enlarging rice yield by using a subirrigation utilizing an underdrain pipe.SOLUTION: Concerning paddy rice untilled well-drained paddy field V-groove direct sowing cultivation in which a dissemination groove 16 having a V-shaped groove cross section is formed in a paddy field 12 enabling a subirrigation 10 utilizing an underdrain pipe 10a, and a paddy rice seed and a fertilizer are disseminated and fertilized simultaneously into the dissemination groove 16 by using a direct seeder, a dissemination method of the paddy rice untilled well-drained paddy field V-groove direct sowing cultivation is provided, which is formed by allowing a longitudinal dissemination groove 16a to intersect orthogonally with a crosswise dissemination groove 16b in the paddy field 12.SELECTED DRAWING: Figure 1
