Abstract: This study was aimed to screen the corresponding cultivation technique of forage with high yield and superior quality which was suitable to be promoted in Songtao Miao Nationality Autonomous County of Guizhou Province. The experiment was conducted using a randomized block design. The productive performance and quality of forage under different interplanting patterns with Pennisetum purpureum cv. Guiminyin and tall fescue were determined. The results showed that under the pattern of Pennisetum purpureum cv. Guiminyin interplanting two lines of tall fescue, the total fresh grass yield was up to 14666.53 kg/667 m^2,and the economic benefit was 5866.61 Yuan/667 m^2 which was 3926.48, 182.07, 601.31 Yuan/667 m^2 higher than that under the pattern of single planting tall fescue and Pennisetum purpureum cv. Guiminyin interplanting one line and three lines of tall fescue,respectively. In conclusion, the interplanting pattern of Pennisetum purpureum cv. Guiminyin ＋ two lines of tall fescue not only greatly increases the forage yield in unit land area, but also meet the demand of animal husbandry development of Songtao region from March to September for green fodder and early spring forage feed. Furthermore, under this interplanting pattern, the forage exhibited superior nutritional quality and significant economic benefits are brought, indicating that the interplanting pattern is suitable to be promoted in this region.
