Abstract


Mixed culture is a pasture sowing methods , the mixed grassland forage production , excellent quality, good quality . This test tested forage the Aohan alfalfa (Medicago sativar CV.Aohan) and sibiricus ( Elymus sibiricus. L.) sequestration of grasslands workstation by Chifeng City . 2009 to 2010 in a demonstration base of the the Chifeng Comprehensive Experiment Station forage test six different mixed culture treated grass population biology , forage yield , interspecific competition and other observational studies, production of crude protein production per unit area of ??grassland (CP) to infer the best combination of the present experiment . The test results are as follows : ( 1 ) 2009 to 2010 the alfalfa alfalfa and E.sibiricus , growth height mode against sowing methods and different Mixture Proportion . 3 treatment within two years among mixtures of three processing hay production was significantly higher than peer Mixed cropping , mixed culture on hay yield higher than Mixture Proportion . ( 2 ) mixed culture extend the biomass accumulation time , the competitiveness of alfalfa mixtures between line processing is greater than the the mixed culture counterparts alfalfa competitiveness . (3 ) year sowing mixed culture did not play increase the role of unicast highest yield of the crude protein of alfalfa forage yield per unit area ; handle 1:2 1:1 processing and inter- row mixtures of crude protein yield and unit area in the 2010 line mixed culture The yield of the above unicast alfalfa and other processing . Within two years of mixed sowing inter- line treatment 1:1 is superior to other mixed culture treatment .
