Abstract: Aiming at the existing problems in the production of Alfalfa,The study proposes and describes the consideration to grass and grain planting pattern of alfalfa, corn, and triticale in order to improve agricultural productivity and economic benefits. The study explores the influence of three crops different planting and matching ways on yield and economic benefits by a split plot design with Alfalfa rows as main treatment and corn/ triticale rows as secondary treantment, And try to explain the competition relationship of different crops simply through yield analysis. The results showed that the planting pattern contains 5 rows of alfalfa , 2 rows of corn and 4 rows triticale is considered to be the best. The spatial and temporal collocation of the three crops is most reasonable. The pattern is beneficial to the mutual promotion among crops, could minimize the losses caused by interspecific competition, and get the best yield and economic benefits.
