摘要: 本研究利用EPIC模型对北京顺义地区的春播紫花苜蓿当年生长中的地上部生物量的累积和刈割进行了模拟。结果表明,EPIC模型可以较好的模拟地上生物量累积;在对刈割的模拟中,地上部生物量和产量的模拟结果可以接受,但对于留茬的模拟结果不理想。

Abstract: In this study, the simulat ion of alfalfa growth and harvest in its f irs-t year growth was made using EPICmodel in Beijing.The results showed that the EPIC model predicted well the alfalfa aboveground biomass. For the cutting,the results of simulation did not differ significantly from the experimental data for aboveground biomass and yield, but forthe residue.the residue.
