    Abstract:

    Three kinds of anti-blocking mechanism, i.e. powered-chain, powered-disc and strip-rotating, for wheat no-till planting had different performance and adaptability, the passing ability, soil disturbance, fuel consumption, yield, etc., were analysed through field experiment. The experimental results indicated that all the three mechanism have the passing ability when the corn stalk is chopped and returned to the field. But the strip-rotating exceeds the others when 100% corn stalks residue covers the soil surface. Compared with strip-rotating and powered-disc, powered-chain has a less soil disturbance, fuel efficiency, better plant performance and yield. 
