Abstract: The tobacco straw was used as the test material,the tobacco straw was used to replace the corn straw, corn cob and other raw materials to cultivate the Agaricus bisporus, and effects of three kinds of material on the yield and weight of the Agaricus bisporus were studied. The results showed that the bud of the Agaricus bisporus with tobacco straw was concentrated and the first tide mushrooms accounted for more than 60%. The yield of the three tide mushrooms was above 18 kg/m². Compared with the traditional corn stalk, the total output and average weight of the Agaricus bisporus cultivated with tobacco straw increased significantly. Compared with the corn cob, the total output and average weight of the Agaricus bisporus with tobacco straw was not significantly.

Key words: tobacco straw, Agaricus bisporus, the total output
