目前,在我省水稻生产上,育苗时采用的床土调酸材料主要是工业用浓硫酸。由于它是液体,在使用、运输、贮藏过程中要求比较严格,也易造成伤害,而且货源短缺,价格较贵(每吨约200～300元),所以在生产中受到了一定的限制。为了探讨用塑料工业的废弃物糠醛渣来代替浓硫酸作水稻苗床土壤的调酸材料,我们于 At present, in the rice production in our province, bed soil used in raising seedlings is mainly acid-based concentrated sulfuric acid. Because it is a liquid, it has strict requirements in use, transportation and storage. It is also easy to cause injury, and the supply is short and the price is more expensive (about 200-300 yuan per ton). Therefore, it is limited in production. In order to explore the plastic industry waste furfural residue instead of concentrated sulfuric acid as rice seedbed soil acidification material, we
