北方地区许多乡镇在建砖厂时,为避免毁田烧砖,都选择了荒山丘土作土源.这样既能吃丘造田,又能为国家建设增砖添瓦.总结我们利用山丘土生产砖瓦近30年的经验,以及我厂化验室十几年来对自治区内外数10家砖厂进行的土质调查与土样理化分析结果,我认为北方地区利用山丘土制砖瓦,一定要注意以下问题. When many townships in the northern region built brick factories to avoid destroying the land and firing bricks, they chose barren hills as their source of soil. This way, they can both eat hills and make land, and they can add bricks and tiles to the country’s construction. Summarize the use of hills and soils. Nearly 30 years of experience in producing bricks and tiles, as well as the results of soil investigations and physicochemical analysis of soil samples from 10 brick factories both inside and outside the autonomous region in our factory’s laboratory for more than ten years, I believe that in the northern regions, the use of hills and earth to make bricks and tiles must be Pay attention to the following questions.
