Embodiment 1

[0027] The invention provides a kind of breeding method of forage grass, specifically comprises the following operation steps:

[0028] Step 1: Configure the dominant parent:

[0029] (1) Select sudangrass seeds and sorghum seeds with full particles and no moth-eaten phenomenon as parent material A and parent material B of pasture seeds respectively, sow 2-2.5kg / mu seeds, and will be selected in 10-15 days before sowing The good seeds are stacked into a thickness of 3-4cm, exposed to the sun for 4-5 days on sunny days, and recycled indoors on cloudy days and at night, so that the seed coat will crack due to heat expansion and contraction, and the gas exchange inside and outside the seeds will be accelerated, thereby Release the dormancy of seeds, accelerate the germination of seeds, and increase their survival rate;

[0030] (2) Soak the sun-dried seeds in water at 26-28°C for 12 hours before sowing, then remove them, and place them in an environment of 30°C for 8-10 hours of...

Embodiment 2

[0038] The invention provides a kind of breeding method of forage grass, specifically comprises the following operation steps:

[0039] Step 1: Configure the dominant parent:

[0040] (1) Select sudangrass seeds and sorghum seeds with full particles and no moth-eaten phenomenon as parent material A and parent material B of pasture seeds respectively, sow 2-2.5kg / mu seeds, and will be selected in 10-15 days before sowing The good seeds are stacked into a thickness of 3-4cm, exposed to the sun for 4-5 days on sunny days, and recycled indoors on cloudy days and at night, so that the seed coat will crack due to heat expansion and contraction, and the gas exchange inside and outside the seeds will be accelerated, thereby Release the dormancy of seeds, accelerate the germination of seeds, and increase their survival rate;

[0041] (2) Soak the sun-dried seeds in water at 26-28°C for 12 hours before sowing, then remove them, and place them in an environment of 30°C for 8-10 hours of...

Embodiment 3

[0049] The invention provides a kind of breeding method of forage grass, specifically comprises the following operation steps:

[0050] Step 1: Configure the dominant parent:

[0051] (1) Select sudangrass seeds and sorghum seeds with full particles and no moth-eaten phenomenon as parent material A and parent material B of pasture seeds respectively, sow 2-2.5kg / mu seeds, and will be selected in 10-15 days before sowing The good seeds are stacked into a thickness of 3-4cm, exposed to the sun for 4-5 days on sunny days, and recycled indoors on cloudy days and at night, so that the seed coat will crack due to heat expansion and contraction, and the gas exchange inside and outside the seeds will be accelerated, thereby Release the dormancy of seeds, accelerate the germination of seeds, and increase their survival rate;

[0052] (2) Soak the sun-dried seeds in water at 26-28°C for 12 hours before sowing, then remove them, and place them in an environment of 30°C for 8-10 hours of...

Abstract

The invention discloses a pasture breeding method, specifically belonging to the technical field of pasture planting. The pasture breeding method specifically comprises the following operation steps:preparation of parents of a superiority combination; intergeneric hybridization seed selection; mutagenesis treatment, and interspecific hybridization of sibling species. Pasture cultivated by using acombined manner of intergeneric hybridization, mutagenesis treatment and interspecific hybridization of sibling species not only has the same characteristics of strong tillering capability and good regeneration as Sudan grass, but also has the same characteristics of low toxicity, drought resistance, waterlogging resistance and saline-alkali resistance as sorghum, and further has the same characteristic of good disease and pest resistance as Collinsonia canadensis; and the cultivated pasture is high in yield, large in leaf width, thick and strong in stalk, resistant to mowing, good in palatability and high in environmental adaptability.

Description

technical field [0001] The invention relates to the technical field of pasture planting, more specifically, the present invention relates to a method for breeding pasture. Background technique [0002] Grass generally refers to grass or other herbaceous plants used by livestock. It has strong regeneration ability and can be harvested many times a year. Forage in a broad sense includes green fodder and crops. As forage grass, the best conditions are vigorous growth, soft grass, high yield per unit area, strong regenerative ability, multiple harvests in a year, good palatability to livestock, rich in high-quality protein in nutrition and proper amount necessary for long bones Phosphorous calcium and rich vitamins and so on. [0003] Grass is the basis for the development of livestock production, especially the production of grass-fed livestock. Grass not only contains various nutrients necessary for livestock, but also contains crude fiber which is especially important for ...
