Abstract:

Leymus chinensis is a famous Poaceous forage in China, with a history of breeding and improvement programs spanning more than 70 years. It plays an important role in ecological construction and animal husbandry production. As at the beginning of the 21st century, L. chinensis had played an important role in the development of the modern dairy industry. However, as China enters the current new development period, with the alfalfa and forage oats industries booming, the L. chinensis industry is in a depressed state. However, China’s alfalfa and forage oats industries are facing many difficult challenges (such as land and water shortages); Hence, it is particularly important and urgent to examine the new advantages and new meanings of revitalizing the L. chinensis industry with new ideas, new perspectives and new technologies. Compared with forage oats, L. chinensis has obvious advantages in both stress resistance eco-biology and cultivation requirements. However, due to the limited policy support for the L. chinensis industry, its development lags behind that of the alfalfa and forage oat industries. In the future, policy support for the L. chinensis industry and scientific and technological innovation should be strengthened. Major breakthroughs should be pursued in the “three-low” problems (low heading rate, low seed setting rate and low germination rate) and seed yield improvement. Greater progress should be an imperative in the key core technologies of the whole L. chinensis industrial chain, such as large-scale planting, intelligent management, water-saving irrigation, mechanized operation, standardized processing, specialized production and competitive cost of the forage to users. Significant effort should be expended to expand the planting area, improve the quality and increase the yield of L. chinensis, as well as to realize the win-win situation for both ecology and economy. Full play should be given to the ecological and biological advantages and cultural biological characteristics of L. chinensis, by developing its use on marginal land, so as to break resource constraints, cultivate leading enterprises, establish a digital trading platform, open up the sales channels of products, and create well-known L. chinensis products and brands.
