| Abstract: | Two plot experiments were performed to examine the effects of varying K-fer-tilization rates on the growth,nutrient uptake and rice yield of rice plant,and soil K-supply-ing ability of the new- cultivated paddy field reclaimed from sandstone in Jiangyong County,Southern Hunan Province. According to the results obtained,the reasonable K fertilizationrates are recommanded for early rice and later rice in new-cultivated paddy field, respective- ly. |
