Description

technical field

[0001] The invention relates to a sinusoidal peak-valley type soybean precision no-tillage seeder with seedlings, belonging to the field of agricultural machinery. Background technique

[0002] Soybean is an important economic crop and an important oil crop in my country. my country's soybean demand has been continuously rising. In order to solve my country's soybean demand, my country's soybean planting area continues to increase. However, there is currently a lack of standardized soybean planters in the domestic market that match the planting model of the Huanghuaihai region. At present, the soybeans in the Huanghuaihai region are small. Field planting mostly adopts rotary tillage with walking tractors, manual fertilization, and manual sowing. Large-scale planting basically realizes a series of work such as mechanized land preparation, sowing, and fertilization. However, the seeds broadcast by each sowing row of the existing soybean planter Arranged in a sin...
