Abstract
On alfalfa grassland in Yellow river beach,a field experiment was conducted to study effects of selenium and cobalt combined basal fertilizers on photosynthesis and production performance of alfalfa(Medicago sativa L.).The results showed that selenium and cobalt combined basal fertilizers could raise chlorophyll content in leaves,enhance net photosynthetic rate and enhance production rate of dry matter from ramification to florescence.When applying 570g/hm2 and 762g/hm2 of selenium and cobalt respectively,combined basal fertilizers had optimal effects which chlorophyll content in leaves could be raised by 6.41%(P0.05),net photosynthetic rate could be promoted by 5.65%(P0.05) from ramification to florescence,aboveground biomass was increased by 8.1%(P0.05) in florescence.
