摘要
大气CO2浓度升高使作物光合效率提高、生长速度加快、根系发达、株高增加、生育期缩短、产量提高、品质下降。因此,作物育种应培育相对晚熟品种,加强抗倒、抗病虫育种,注重品质改良。
With atmospheric CO2 concentrations elevated, increased the photosynthetic efficiency of crop, speeded up the growth, enriched the root system, increased the plant height, shortened the growth period, increased the production, de- clined the quality. As a result, we should be breed varieties to possess relatively late maturing, strengthen the lodging re- sistance and disease resistance, improve the quality.
