| 摘 要： | 以黑龙江省大庆市林甸县长青林场3个不同小区为实验地,分别采用酸雨石等5种吸盐材料对不同小区盐碱土壤进行改良,根据改良后土壤pH、导电率变化,对不同材料的盐碱土壤改良效果进行比较。研究表明,短期内吸盐速率:酸雨石活性炭腐熟牛粪沸石稻壳,长期吸盐量:酸雨石活性炭沸石稻壳腐熟牛粪,效果持久性为酸雨石最强,活性炭、沸石次之,稻壳较弱,腐熟牛粪最弱。酸雨石解碱能力最强,活性炭次之,沸石、牛粪、稻壳解碱能力较弱。因此,酸雨石在5种盐碱土改良剂中具有最强吸盐解碱能力。

| Abstract: | Five kinds of salt-absorbing materials, such as acid rain stone, were used to improve the saline-alkaline soil in three different experimental plots in Changqing Forest Farm of Lindian County, Daqing City, Heilongjiang Province. The improvements of saline-alkaline soil were compared based on the soil pH and conductivity variation of soil. The results suggested that on short-term salt-absorption effects, acid rain stone > activated carbon > composted cow manure > zeolite > rice hull. On long-term salt-absorption effects, acid rain stone > activated carbon > zeolite > rice hull > composted cow manure. On effect of salt-absorption persistence, acid rain stone was the best, followed by activated carbon, zeolite, rice hull, and composted cow manure in sequence. In addition, for the ability of neutralizing alkali, acid rain stone was the strongest, followed by activated carbon, zeolite, composted cow and rice hull. Overall, acid rain stone had the strongest ability of salt absorption and alkali neutralization among five kinds of materials. |
