【 摘 要 】

In 2010 and 2011, the characteristics of seedling establishment, dry matter production, and yield of rice direct-seeded by simultaneous seeding with fertilizer application were compared with those of rice direct-seeded in accordance with conventional practice to establish a direct seeding culture method using an air-assisted row seeder in a cold climate area. In the simultaneous seeding with fertilizer application, the rate of seedling establishment was the same as that in the conventional practice. After seedling establishment, top dry weight, stem number, Leaf area index and nitrogen absorption in the simultaneous seeding with fertilizer application were the same as or superior to those in the conventional practice. Thus, the yield was the same as or higher in the simultaneous seeding with fertilizer application than in the conventional practice.
