Present State and Development on Technology of Stubble Chopping

The significance of breaking stubble, especially for maize, was discussed in this paper, and the development of the technology of chopping stalk and stubble was introduced. On the basis of analyzing the structure and performance of a few of types of multiplex chopping implements widely used in North China, the problems in the technology of chopping stubble were pointed out. It was put forward that computer analogy, imitation and image manipulation of chopping process, precise chop of stubble using high technology and the better combination of agronomy with agricultural machinery should be taken as the direction of future study in this area.
