Supporting Seeder and Planting Technology for Spring Corn in Arid Areas.

The annual rainfall is low and the fresh water resources are scarce for the rainfed farming in dry zone of northern China, which seriously affects the sowing and growth of spring com. In order to solve this problem, the technology of ridge-mulching and side-sowing of spring com is put forward, the supporting compound operation seeder is developed, and the effect of different speed on the quality of sowing is tested and analyzed. Under the test conations described in this paper, the seeding operation with a high speed (up to 6 km/h) can be realized, and the quality of the seeding operation can meet the requirements of the national standards. The application of this machine can solve the problem of "drought damage at the booting stage" for spring corn, thereby realizing the deep fusion of farming machine and agronomy in dry farming of northern China, and achieving the integration of farming machine and agronomy.
