The research on the field soil salinity environment change with different drip irrigation years

摘要：

With the increasion of the application years under-mulch drip irrigation,the field soil salinity environment change and its influence on the crops cause the concern.To choose the field close and continuously apply under-mulch drip irrigation about 2-14 and the cotton field 8 pieces in order to monitor soil salinity variation.The results initially show that :the soil of inner mulch with 0-20cm soil desalts,from40cm to 80cm accumulates salt;between the mulch bare land the soil salinity on the surface assembles,above the 60cm the soil salinity accumulates,below the 100cm the soil salinity is close to the inner mulch.The soil salinity content within four drip irrigation years is relatively high,is comparatively low over 6 drip irrigation years.the field salinity environment is relatively good.From 0 to 40cm the soil salinity content decreases with the drip irrigation years increases at the end of the growth process;from 60 to 100cm the accumulated salinity with the drip irrigation four years is highest.Suggest enlarging the salinity regulation dynamics within 6 drip irrigation years.
