Abstract: The rice varieties using biogas manures (BM ) and a few chemical fertilizer grow more slowly in the early growing season，but turn to he better in the late growing season，and more filled grains per panicle，higher full grain rate，higher 1000-grain weight can be obtained than those using chemical fertilizer or special fertilizer for rice．However，the yield has no obvious effect of increase than that using chemical fertilizer．and is 4．6％ lower than that using fertilizer special for rice During the whole rice growing season．the costs of using biogas manures are cut down 19.0％ and 42.5％than that of using chemical fertilizer and fertilizer special for rice，respectively．Furthermore，cultivating rice with biogas manures can improve the soil physicochemical characters．
