| Abstract: | In this paper, the crop growth simulation model LID.CSM developed by Dr. Penning de Vries in 1988, and Fuzzy Maths are used to analyze the potential yield of two cropping systems under the effect of climate, the limitation of paddy soil fertility. The simulated results showed that the climatic potential yield of wheat/corn-late rice cropping pattern is about 300kg/ha higher than that of whe-at-single rice. The climatic potential yield of corn is greatly affected by the va-riation of annual rainfall, while rainfall has little effects on the potential yield of wheat when the soil is under well drainage condition. Potential yield of three paddy soils, which account for 80% of paddy soil areas, is about 13510.5kg/ha under the wheat-single rice cropping system. The highest yield of wheat under sufficient fer. tilizer supplying account for 70.6% of paddy soil potential yield, while for single rice, its highest yield reaches or is close to the climatic potential yield under the same condition. As for wheat production at present in Danyang city, we should put the emphasis on the increase of soil potential yield.For single rice, emphasis should be put on the increase of climatic potential yield of stra-ins |
