摘  要:
为了探究不同改良剂对滨海盐渍土的改良效果,以河北省中捷友谊农场学院路的滨海盐渍土为研究对象,试验设定5种不同的改良处理:TR1(有机改良剂+天然沸石)、TR2(园林废弃物+天然沸石)、TR3(有机改良剂+园林废弃物+天然沸石)、TR4(天然沸石)、TR5(有机改良剂)以及CK(对照),进行田间试验,分别于改良1个月后以及改良1a后取样,分析并测定土壤8大离子质量分数以及土壤全盐量。结果表明:改良1个月后,5种改良处理均能显著地降低土壤Ca~(2+)、Mg~(2+)和SO_4~(2)质量分数和全盐量;TR2处理和TR4处理能显著降低土壤中K~+质量分数;除TR5处理外,其他4种处理均能显著降低土壤中Na+和Cl-质量分数;只有TR5处理能够显著降低土壤中HCO_3~-质量分数和pH值。改良1a后,5种改良处理均能显著地降低土壤K~+、Ca~(2+)、Mg~(2+)、Cl~-、SO_4~(2)质量分数和全盐量;除TR5处理外,其他4个改良处理均能显著降低Na~+质量分数;改良后土壤pH值和HCO_3~-质量分数均无显著变化。因此,有机改良剂、天然沸石和园林废弃物作为改良土壤降盐材料均有助于滨海盐碱地改良,达到降盐效果。

摘  要:
In order to investigate the effects of applying organic and inorganic amendments on the coastal saline-alkaline soil,field experiments were conducted in Bilateral Friendship Farm in Hebei with six treatments,which were TR1(OSA+Zeolite),TR2(Zeolite+Green- Wast),TR3(OSA+Zeolite+GreenWast),TR4(Zeolite),TR5(OSA)and CK.Soluble salt ions contents were measured to assess the desalination after one month and one year.The results showed that all treatments had significant effects on the desalination(P>0.05),for one month and one year after applying amendments.Compared with the control,the desalting ratios of TR1,TR2,TR3,TR4 and TR5respectively were 32.23%,41.57%,41.77%,42.78% and 23.61% for one month after applying amendments.Application of five treatments into soil could significantly decrease the available contents of Ca~(2+),Mg~(2+)and SO_4~(2) not only after one month but also after one year.TR5 treatment had a significant effect on the contents of HCO_3~- and the value of pH during one month.Compared with the control,the desalting ratios of TR1,TR2,TR3,TR4 and TR5respectively were 67.72%,73.20%,68.44%,70.10% and 46.66%for one year after applying.What's more,TR1,TR2,TR3 and TR4treatments had better effects on the desalination than TR5 treatment after one year.And TR1,TR2,TR3 and TR4treatments all could decrease the available contents of Na+during two periods.However,there were no significant changes of pH and the content of HCO_3~- during one year.To sum up,OSA,Zeolite and Green-Wast were effective salt-reduction materials in the coastal regions of Bilateral Friendship Farm.The results would provide a theoretical basis and valuable reference to select an effective way to ameliorate coastal saline soil.
