摘要
为研究生物有机肥配施脱盐剂、脱硫石膏对苏打型盐碱地改良效果,2020年、2021年连续2年进行了小区定位改良试验。结果表明:0~20 cm、20~40 cm土层的土壤指标,T3处理(生物有机肥+脱硫石膏)下全盐量、pH值改良效果最好,T2(生物有机肥+脱盐剂)次之,T1(生物有机肥)最差;在玉米出苗率、株高茎粗上,均表现为T3处理最好,且与其他2个处理达显著差异,产量表现为T3>T2>T1。各指标年际间均表现为2021年优于2020年。
In order to study the improvement effect of bioorganic fertilizer combined with desalination agent and desulfurization gypsum on soda saline-alkali land,a plot location improvement experiment was carried out in 2020 and 2021.Results showed that in 0-20 cm and 20-40 cm soil layers,the effects of T3 treatment(bioorganic fertilizer+desulfurized gypsum)on total salt content and pH were the best,followed by T2 treatment(bioorganic fertilizer+desalting agent)and T1 treatment(bioorganic fertilizer).In terms of seedling emergence rate,plant height and stem diameter,T3 treatment had the best performance,and it was significantly different from the other two treatments,and the yield showed T3>T2>T1.The interannual performance of all indicators was better in 2021 than in 2020.
