The pneumatic seed sowing device has a complex structure, has high requirement on the air tightness of a cavity, needs a stable air pressure source during operation, and is blocked by suction Kong Yifa to leak suction, so that the seed sowing effect is poor in practical application. The mechanical seed metering device has simple structure, low manufacturing cost and easy operation, and can adapt to changeable and complex field sowing environments.
The current direct seeding variety mainly comprises hybrid rice and conventional rice, wherein the hybrid rice is generally sowed with 2-4 grains per hole due to different tillering capacities of the two kinds of rice, and the conventional rice is generally sowed with 5-8 grains per hole.
