摘要
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。
Based on the data of field observation and controlled environment chamber experiment, the simulation of leaf nitrogen content variation with time and different nitrogen fertilizer application rates during the growth of single-cropping late rice and its effects on net photosynthesis rate as well as dry matter accumulation is carried out by the authors. The growth of grain weight is calculated by biological yield and grain weight distribution coefficient. The simulation result of yield variation with different fertilization schemes could contribute to plan making of field nitrogen fertilizer application
