Forage grass breeding method

Abstract

The invention discloses a forage grass breeding method comprising the following steps: S1, selecting full-grained forage grass seeds without damaged by worms as seeds, and sowing the forage grass seeds into soil; S2, sowing a row of sweet sorghum seeds between two adjacent rows of forage grass seeds; S3, grasping the flowering time, and ensuring the same flowering time of forage grass and sweet sorghum through field management, so as to make the pollen of the sweet sorghum naturally float to spikes of the forage grass to form natural pollination; S4, after the flowering period of the forage grass, obtaining first-generation hybrid forage grass seeds; S5, sowing the first-generation hybrid forage grass seeds to obtain first-generation hybrid forage grass; S6, sowing a row of sweet sorghum seeds between two adjacent rows of first-generation hybrid forage grass seeds; S7, after the flowering period of the forage grass, obtaining second-generation hybrid forage grass seeds; and S8, sowingthe second-generation hybrid forage grass seeds in the soil to obtain forage grass, and thus completing forage grass breeding. The forage grass obtained by sowing of the forage grass seeds after breeding has the advantages of high yield of the forage grass, large leaf amount and good animal palatability.

Description

technical field [0001] The invention relates to the technical field of pasture planting, in particular to a pasture breeding method. Background technique [0002] Grass generally refers to grass or other herbaceous plants used by livestock. Grass not only contains various nutrients necessary for livestock, but also contains crude fiber which is especially important for maintaining the health of ruminant livestock, which cannot be replaced by grain and other feed. High-quality forage can fully meet the nutritional needs of general livestock. If it is not in the production or fattening period, it is generally not necessary to supplement the concentrate. Many experiments have shown that if the quality of forage grass is too low, no matter how much concentrate is supplemented, the milk production of cattle will show a downward trend. It is not ideal, and it is far from meeting the needs of production. The forage grass planted by traditional breeding methods has low yield, poor...

Problems solved by technology

Many experiments have shown that if the quality of forage grass is too low, no matter how much concentrate is supplemented, the milk production of cattle will show a downward trend. Unsatisfactory, far from meeting the needs of production, and the forage planted by traditional breeding methods has low yield, poor quality, small leaf volume, hard stems, and poor palatability
