Abstract: Pot experiment was conducted to study the effect of peat and weathered coal on soil alkali-salinity and rice plant yield in Keerqin sandy area. Results showed that, soil total salt was increased when adding peat or weathered coal mainly because the increasing of soil soluble Ca and Na. Soil organic carbon was positively corelated to the increasing of peat or weathered coal adding, so as to soil available N, P and K. Rice yield was significantly enhanced with the plant height, tiller length and rice grain amount of per tiller were raised.
