Abstract:
In order to ascertain the trend of soil quality with the increasing year of gravel mulched field and improve the sustainable use of gravel-sand mulched fields in arid area of central Ningxia Hui Autonomous Region.Taking gravel-sand mulched wasteland of different years of sand-mulching (1,3,5,7,10,20,30 a) in Hong juanzi Village,Xingren County,Ningxia Hui Autonomous as object,and the soil physiochemical properties of different years of sand-mulching were analyzed by One-Way ANOVA and Pearson correlation.The results indicated that soil moisture,moisture capacity,saturation moisture capacity,capillary porosity,total porosity and saturated hydraulic conductivity presented a declined trend with the increasing year of gravel mulched field and the soil bulk density increased.Soil pH showed nonsignificant trend with the increasing year of gravel mulched field.The contents of organic matter,total salt,total phosphorus,total potassium,total nitrogen,available phosphorus,available potassium and nitrate all decreased significantly with the increasing year of gravel mulched field.The soil physiochemical properties turned to become poor quality gradually.In order to ensure sustainable use of gravel-sand mulched fields,people must fertilize and cultivate scientifically and rationally in the process of farming.
