Grass breeding method

Abstract

The invention discloses a grass breeding method. The technological steps of the grass breeding method comprise that (1) grass and corn are planted according to the planting manner of one row of grass and one row of corn; (2) the flowering time is grasped, the grass and the corn are flowered simultaneously, and natural hybridization pollination is performed; (3) first generation hybrid grass seeds are obtained after the grass flowering phase, and full first generation hybrid grass seeds are selected for use; (4) the first generation hybrid grass seeds are used for planting first generation hybrid grass; (5) the corn is planted among rows of the first generation hybrid grass, the flowering time is grasped, the grass and the corn are flowered simultaneously, and natural hybridization pollination is performed; second generation hybrid grass seeds are obtained after the grass flowering phase; (6) full second generation hybrid grass seeds are selected, and grass breeding is completed. Grass planted through the grass seeds with the breeding method is high in yield, large in leaf quantity, brittle in straw and good in palatability, and the sugar content can be as high as 5%.

Description

technical field [0001] The invention relates to the technical field of pasture planting, in particular to a pasture breeding method. Background technique [0002] At present, forage is an important feed for herbivorous livestock. Breeding of high-yield and high-quality forage is the premise and basis for the development of efficient animal husbandry. The problem is that the limited natural forage or stocking livestock causes vegetation damage and a large amount of water and soil loss, and the area of ​​grassland continues to shrink, which makes it difficult to scale up livestock breeding in our country. In order to overcome the problem of insufficient forage, people have adopted artificial planting forage, but at present, the varieties used in large quantities in the forage industry in our country, such as ryegrass in winter, alfalfa and teosinte in summer (Mexico forage corn), etc. It still relies on imports from abroad, and the level of pasture breeding in my country is st...

Problems solved by technology

[0005] After research, it was found that the above disclosed forage seed production method, the forage obtained by using traditional planting techniques, the yield of the planted forage is not high enough, the stalks are hard, and the palatability is slightly poor
