Research development of Italian ryegrass

Introducing and selecting varieties, situation of breeding varieties of home and abroad and its basic research were summarized In this paper, concluding and summarizing highyield cultivation, high efficiency agriculture grass field system，seed production, forage collection storage technical. Synthesizing high crude protein, good palatability, high digestibility, feeding cattle, sheep, hare, goose, pig, can obviously save grain feed , debase aquaculture cost. Analyzing existing problem of productive practice,in view of popularizing and planting of Italian ryegrass developed grassland husbandry and adjusted agricultural structure, we put forward future research objective and emphases.
