Creeping bentgrass (Agrostis palustris Huds.; Agrostis stolonifera) are often used in golf course greens, tees, and fairways, courtyard and park green space can also be used. Because of its delicate texture, resistance to low pruning, it is applied to the lawn of the high level of conservation and management.

Thin bentgrass the Ying (Agrostis tenius) mainly distributed in the northeastern United States and New Zealand, commonly used in the fairways and greens of the golf course, but also a small amount for the courtyard green space, more common in the old cemetery near. It is a big advantage the upward growth characteristics, however, it is poor tolerance for the ambient pressure (for example, heat intolerance trampling), and uneven lawn varieties, and gradually decreased over time, turf quality. It is suitable for the low pH of the soil is often used in the Mixture.

Annual ryegrass (Lolium multiflorum L.) leaves a rough texture, green for extensive management. Its main advantage is rapid germination floor space fast, but not cold resistant and high temperature. Does not apply to high-quality lawn.

Perennial ryegrass (Lolium perenne L.) is widely used cool-season turfgrass Mixture of Northern Kentucky bluegrass, applied to the courtyard lawns, golf courses and sports turf; used for sowing dormant bermudagrass lawn in the south .
The main advantages of perennial ryegrass germination fast (5-7 days), seedlings of high activity, and therefore floor space quickly (much faster than other cool-season turfgrass), In addition, it has the following advantages: 1) long life; 2) heat; 3) resistant to trampling; 4) insect; 5) resistance to low trim can be used for Bermuda grass in the winter sowing.

The main disadvantage of perennial ryegrass: 1) susceptible to diseases against; 2) leaves hard, and therefore more difficult to trim; 3) rapid vertical growth Mixture easily lead to rootzones uneven surface; 4) sparse cluster growth characteristics, slow to reproduce (some genotypes seem to have the rhizome growth characteristics); 5) vulnerable to frost damage in winter; 6) as repair damaged lawn grass, or Bermuda grass in the winter sowing grass seed, it showed too much lasting impact normal turf quality.
