摘要
PURPOSE:To provide a process for the application of a sprout-promoting material and an application apparatus to promote the sprouting and stabilize the yield by applying a sprout-promoting material to seeds in sowing under a field condition to cause the dissolution of the soil surface by a large amount of rainfall after sowing a direct sowing crop and the formation of a soil crust by the following dry weather to inhibit the extension of the sprouted seed to the ground surface. CONSTITUTION:The present application process comprises (a) the opening of a furrow and the sowing of seeds 1, (b) the application of a sprout-promoting material 2 and covering with soil and (c) the tamping of the soil surface. The application apparatus is composed of a conventional sowing machine 7 and a main body 8 of the sprout-promoting material application apparatus placed at the back of the sowing machine. The apparatus is provided with a hopper 8A of a sprout-promoting material placed above the sowing machine 7, a chute 8D connected to a delivery roll 8C placed just below the lower opening of the hopper 8A and a rear opener 8E placed below the chute 8D. The rear opener 8E is positioned at the back of the opener 7C of the sowing machine 7.
