A green manure embedding machine was developed according to the operational principle of rotary spade. The main structure and working process of the machine were determined. The lengthwise edge of the blades can effectively prevent the blades from winding the grasses by using the sine index curve. A top plate was equipped to assist the furrow slice to turn over. A soil scraping device was equipped to scrape the soil adhering to the blade. The results of field tests showed as follows: the green manure coverage rate was more than 85%,the maximum tillage depth was 200 mm. The power consumption of the machine was lower. This machine meets the design requirements and returns green manure,rice straws and wheat straws to the field through mechanization operation. It would be important, practical and valuable to improve the utilization ratio of the existing straws.
