Ryegrass is a high-quality pasture for raising pigs, geese, fish, rabbits, sheep, cattle and other livestock. Planting grass and raising livestock has been an excellent model of combining planting and breeding in recent years, and is a good way to obtain higher economic benefits. A good way to achieve benefits, ryegrass is the best variety for winter pasture. It has the advantages of good adaptability, easy planting, high yield, good nutrition and good palatability.

Ryegrass is a world-renowned fine grass with a wide planting range and is grown in both southern and northern regions of my country. In the southern region, ryegrass, especially "Jiewei" Lolium multifolram (annual ryegrass), has the characteristics of fast growth in winter and spring, high grass yield, rich leaves, good palatability and nutritional value. Due to its high yield and strong stress resistance, it is very popular among herdsmen and has become the preferred cultivated grass in winter and spring. In addition, "Jiewei" ryegrass is a cool-season grass, which does not affect spring grain production, but also makes full use of winter fallow land resources, and can produce excellent forage with a biological yield 4-5 times that of spring grain. Therefore, "Jiewei" ryegrass has become the "grass of hope" for growing grass and raising livestock in agricultural areas, and its development prospects are very broad.

Jiewei multifloral ryegrass is a broad-leaf, tetraploid variety introduced by Sichuan Jinzhong Liaoyuan Seed Technology Co., Ltd. from Dannon International Seed Company (USA) in 1999. After several years of product comparison, regional testing, and promotion and application in different areas of Sichuan, Jiewei multiflora ryegrass has shown strong adaptability and stability, as well as wide leaves, strong plants, resistance to lodging, resistance to frequent mowing, and rapid regeneration. It has the advantages of high grass yield and strong disease resistance. In December 2004, Jiewei Multiflora Ryegrass passed the approval of the National Forage Variety Approval Committee and was confirmed to be an imported excellent forage variety suitable for promotion and application in southern areas with good water and heat conditions such as Sichuan, Chongqing, Guizhou, Yunnan, Hunan, and Guangxi. Variety registration certificate number 289.
