摘　　要：利用农业废料棉花秸秆制作棉花秸秆草砖。根据棉花秸秆的形状特点,研究棉花秸秆草砖制作工艺;并对草砖的力学性能进行测试,研究草砖的承载能力与压缩率之间的关系。实验结果表明,棉花秸秆合理的摆放和草砖密度的控制是制作的棉花秸秆草砖的关键;不同方向放置的草砖力学性能和压缩率表现差异较大。Preparation of cotton straw hale with agricultural waste cotton straw is studied. According to the shape characteris- tics of cotton stalks,the cotton straw bale production process is discussed;And related experiments are made on the mechanical properties of grass brick to research the relationship between the bearing capacity of the grass brick and its compression ratio. The experimental results are as follows：reasonable layout of cotton stalks and good control of straw bale density are the key to the pro- duction of cotton straw bale. There are big differences in the mechanical properties and compression ratio of the grass bricks put in different directions.
