- Abstract:
- The desalting effect of drip irrigation amount and soil amendments ratio on the coastal saline soil were discussed under the condition of simulating drip irrigation through soil column for the purpose of quick desalination of coastal heavy solonchack with low cost. The influence of soil amendments on soil infiltration and desalting effect were analyzed by orthogonal experiments design, and desalination modifier of muddy coastal heavy solonchak was screened. The results suggest that the irrigation amount of 0.26 m3/m2 is the best drip irrigation schedule, the desalination rate is over 78.73%, which can achieve rapid desalting. According to the analysis of orthogonal design, the sequence of the influences of 5 kinds of modifiers on soil total salt is phosphogypsum > humic acid > organic matter > ZnSO4 > straw, sequence of influence on soil pH value is phosphogypsum > humic acid > ZnSO4 > straw > organic matter. Finally, the best proportion of soil amendments of muddy coastal heavy solonchack is A1 B1 C2 D2 E4, which is 0.05 m3/m2 straw, 3 kg/m2 phosphogypsum, 0.05 m3/m2 organic fertilizer, 0.03 kg/m2 humic acid + 0.03 kg/m2 ZnSO4.
