根据大田和人工气候箱试验资料,模拟了单季晚稻生长过程中叶片含氮量随施肥量和时间的变化规律,及其对净光合速率和生物学产量及籽粒增重过程的影响,通过模拟不同施肥策略下产量的变化,为大田肥料运筹提供了参考依据。
According to field and artificial climate chamber data, the changes of nitrogen content in leaves of single late rice with fertilizer amount and time were simulated and their effects on net photosynthetic rate, biological yield and grain weight gain were simulated. The changes of yield under different fertilization strategies provided the reference for the operation of field fertilizer.
