摘  要:
[Objective] To explore the mixture sowing effects and optimal mixture ratio of alfalfa and orchard grass. [Method] The alfalfa and orchard grass were sowed at different ratios (1∶0, 3∶1, 1∶1, 1∶3 and 0∶1). They were grouped and named as CK1, A1, A2, A3 and CK2, respectively. The forage yield, relative yield total (RYT) and the competition rate (CR) of alfalfa and orchard grass in each group were determined, respectively. [Result] In the A3 treatment group, the total forage yield was the highest (4 827.67 kg/hm2) and significantly different from that of other treatment groups (P 0.01). In every treatment group, the RYT was higher than 1, and the alfalfa was more competitive than the orchard grass in the mixed-seeding pasture. [Conclusion] Our studies may provide a basis for the establishment of high yield and high quality artificial mixture pasture.
