摘要: 采用Farquhar数学模型对3种覆盖措施下春小麦的光响应曲线进行了模拟分析,并计算了不同覆盖措施下春小麦光合特征参数。模拟结果显示:RMSE的变化范围为0.29~0.59,R2的变化范围为0.99,拟合效果极佳。春小麦光合特征参数显示,地膜覆盖措施较其他覆盖措施更有利于提高春小麦的最大净光合速率,且具有最高的光饱和点和较低的光补偿点,并使春小麦暗呼吸速率消耗减小,是春小麦光合产量累积的最佳种植方式。

Abstract: Abstracts: Spring wheat photosynthetic light response curve was analyzed under three kinds of mulching treatments by Farquhar mathematical model, and the photosynthetic characteristic parameters of spring wheat under different mulch treatments were calculated. The results showed that there was a good imitative effect with RMSE ranging from 0.29 to 0.59 and the correlation coefficient range (R2) of 0.99. The photosynthetic characteristic of spring wheat showed that the plastic film mulching treatment had better improvement effect on the maximum net photosynthetic rate of spring wheat than other mulching treatments, and it had the highest light saturation point and a lower light compensation point, and it also reduced the dark respiration rate consumption of spring wheat. So the plastic film mulching treatment was the best planting way to photosynthetic production accumulation of spring wheat.
