Abstract
According to current requirement ment of prataculture production in Henan province,a field experiment was conducted to study the effect of selenium and cobalt combined fertilizers on disease prevention of alfalfa(Medicago sativa L.) under the conditions of basal fertilization before sowing in order to promote green production of forage products of alfalfa.The results showed that selenium and cobalt combined basal fertilizer had great disease prevention effect on rust,brown spot,summer black stem and appeared more obvious effects in flowering-ripening stage.Under combined basal fertilization when application rate of selenium was 76.5 g/hm2,that of cobalt was 76.2 g/hm2 and 157.2 g/hm2 respectively,rust,brown spot,and summer black stem could be prevented effectively,and alfalfa rust could be decreased by 24.7% and 31.6% respectively,brown spot could be decreased by 25.2% and 22.7% respectively,summer black stem could be decreased by 25.2% and 19.0% respectively.Furthermore,selenium and cobalt combined basal fertilizer also had obvious preventing effect on root rot which could be decreased by 19.8% and showed more obvious effects in pods formation-ripening stage when selenium application rate being 57 g/hm2 and cobalt application rate being 157.2 g/hm2.
