Abstract: In order to better promote and apply protective tillage techniques in the Jianghan plain, and fulfil the farmers’ demand for no-tillage soybean planters in this area. According to the quailty of no-tillage planters seeding detection index and method of provisions of the Ministry of agriculture machinery test station and national standards and the agricultural industry standards, the field performance test of 2BMFJ-6 multifunctional no-tillage soybean straw covering planter was carried out under two kinds of natural stubble surface conditions in Jianghan plain, and the operation quality and adaptability of the seeder were analyzed. The results showed that the planter was higher than the national qualification standard in planting performance indicators such as machine’s trafficability, it depth of seed fertilizer, the uniformity of sowing, and the rate of airing seeds,etc., This machine has good trafficability and seedability, and has stable performance. It has strong adaptability in the natural stubble land in Jianghan plain and can meet the requirements of soybean precision sowing.

Key words: conservation tillage, soybean no-tillage planter, field performance test, adaptability
