Abstract
The aim of this research was to promote forage production in soils insufficient in selenium(Se) and cobalt(Co) by basal dressing of Se-Co combined fertilizers in alfalfa(Medicago sativa L.) grassland.An experiment was conducted in Yellow River beach areas for 3 years from 2006 to 2008 and the effect of Se-Co combined fertilizer on the productive performances of alfalfa was evaluated in order to improve the growing environment and enhance the forage yield and quality of alfalfa.The results show that basal dressing of Se-Co combined fertilizer increased the net photosynthetic efficiency,decreased the plant respiration loss,and enhanced the production rate of dry matter from budding to flowering stage in favor of the alfalfa hay production before flowering stage.Among the 4 combined fertilizers,the application rates of Se at 570 g·hm-2 and Co at 765 g·hm-2 had best effects on forage production,forage yield,1000-grain weight,and underground biomass in soil depth of 0-20 cm which were increased by 8.0%(P0.05),12.5%(P0.01),and 1 4.6% within two years,respectively.
