秸秆覆盖还田是保护性耕作技术的核心技术之一，可以有效减少环境污染和大田水分蒸发，提高作物产量，而不同秸秆覆盖量对土质状况又有不同的影响。为此，就不同玉米秸秆覆盖处理对土壤质量的影响进行了试验，并在小麦全生育期的3个阶段进行采样，分析了不同时期不同处理下土壤质量的变化，然后进行模糊综合评价。结果表明，较优的秸秆处理方案为50％覆盖有腐解剂，较优的秸秆覆盖量为50％覆盖，即半覆盖量。

Straw mulching , which is one of the core technologies of conservation tillage techniques , can effectively reduce environmental pollution and field evaporation , and increase crop yields .Different straw mulching has different effects on the quality of soil.In this paper,we tested different effects of corn straw mulching on soil quality ,sampled at three stages of the whole growth period in the wheat , analyzed the changes of soil quality in different periods and different process-ings, and then proceed to the fuzzy comprehensive evaluation .We come to a conclusion: a better treatment program of straw is that fifty percent of the straw mulching has the decomposing agent , and optimum ratio of straw mulching is 50%, semi-cover volume .
