Abstract:
The spatial movement of soil salinity with different straw returning methods in greenhouse was studied.Total soil salinity，conductivity,soil nitrate and pH value of different soil depth under different straw returning method treatments were determined.Different saline indexes were compared between different treatments.The correlations of different saline indexes were analyzed.The results showed that there were not significant differences between straw reactors under the ridge 2 000 kg/667m2 to regulate soil saline indexes.Straw reactors under the ridge can decrease soil total salinity from 0 to 10 cm soil depth 20.16%-21.75%，decrease soil total salinity from 10 to 20 cm soil depth 13.25%-24.40%，decrease soil nitrate from 0 to 10 cm soil depth 25.00%-25.80%，decrease soil nitrate from 20 to 30 cm soil depth 22.41%-24.75% respectively than CK(no straw).There was a significant positive correlation between total soil salinity and soil nitrate.There was a significant negative correlation between total soil salinity and pH value.
