Abstract: In view of the current development status of ecological animal husbandry of meadow and forage grass resources utilization in Songtao Miao Nationality Autonomous County of Guizhou Province, a study on different interplanting patterns of hybrid giant napier and tall fescue was designed and performed. The results showed that when hybrid giant napier was interplanted with two lines of tall fescue, the total yield of fresh grass was up to 15 387.69 kg/667 m^2,and the highest economic benefits reached up to 6 155.08 Yuan/667 m^2, which were 4 188.76 Yuan/667 m^2 higher than those in the mono culture pattern of tall fescue, and were 102.72 Yuan/667 m^2 and 696.61 Yuan/667 m^2 higher than those when hybrid giant napier was interplanted with one line and three lines of tall rescue, respectively. Our results demonstrate the extension of the interplanting pattern that hybrid giant napier was interplanted with two lines of tall fescue in Songtao region can greatly increase the fresh grass yield in unit land area and improve the comprehensive utilization efficiency of land resource and famers＇ income.
