The air suction type precision seeding is divided into 3 main modes of suction needle type, drum type and sucking disc type, wherein the suction needle type seeding machine is widely applied due to accurate seeding, good seeding performance and adaptability to the shape and size diversity of seeds. Most of the principles of domestic automatic sowers are that two parts of soil in a cavity are filled, a hole punching device and a soil filling device after sowing are needed, the steps are complicated, the efficiency is low, and the positions of seed suction and seed sowing are needed to be determined.
However, the existing seeder generally adopts a mode of seeding from top to bottom, and the seeding mode from top to bottom has the advantage of conforming to the design of the plug tray, so that the seeding can be realized in a simpler mode. The sowing depth of the plug is different according to different seeds, but is generally about 1.0cm, the height of the plug is 2.3-6 cm, and the size of a standard 72-hole plug is 540 gamma 280cm; seed hole size: upper gamma bottom gamma depth: 38 gamma 22 gamma 42mm.
