Abstract: Straw burning or throwing out at random is one of the main problems destroying ecological environment of our country. This paper analyzed the objective reasons for straw regional, seasonal, and structural surplus described by  the literature and policy documents, and put forward the thoughts about straw utilization way and method from the angle of technology and research. The major objective reasons of straw regional, seasonal and structural surplus were increased straw yield, reduced consuming quantity of straw by traditional utilization method, continuous increasing of straw using cost and changes in planting pattern, etc.. All these factors intensified the contradiction between harvest and planting seasons. Adopting measures of  improving varieties, optimizing crop distribution, and adjusting planting patterns could reduce the straw yield. Vigorously developing straw biomass energy industry could fortify consuming nearby straw. Accelerating R & D of matched machinery and equipment could enhance the straw collecting efficiency. Making overall plans to develop economy, society and ecological effect, etc. sustainable agricultural technology were favorable for solving straw surplus problem and promoting the full dose utilization of straw.

Key words: straw surplus, regional, structural, seasonal, utilization way
