Abstract：The effects of ammonium carboxymethyl cellulose(CMC-NH4)as a soil conditioner on soil moisture,electrical conductivity,nutrients and rice yield in Yucheng paddy field in Shandong Province were analyzed.A field experiment was conducted in Cuili Village,Fangsi Town,Yucheng City,Shandong Province.Rice was used as the test crop,and the CMC-NH4 application rate was 0,75 and 150 kg/hm2(labeled as C0,C1 and C2),respectively.Soil water content,electrical conductivity,soil nutrients and rice yield under different treatments were determined.The correlation between CMC-NH4 application amount and soil physicochemical properties and rice yield was also analyzed.The results showed that the application of CMC-NH4 had no significant effect on soil water content and electrical conductivity compared with C0.The contents of total nitrogen,total phosphorus,available phosphorus and nitrate nitrogen in soil were significantly reduced by the application of CMC-NH4 treatment,which indicated that CMC-NH4 treatment could promote the absorption and utilization of soil nutrients on the whole.The application of CMC-NH4 significantly increased rice yield,and C1 and C2 treatments increased by 11.80％ and 7.60％,respectively.In conclusion,the application of CMC-NH4 could improve the utilization rate of soil nutrients and increase rice yield in newly cultivated paddy field.It could be used as a soil amendment for newly cultivated paddy field.The recommended application amount was 75 kg/hm2.
