[0013] Example 1: Mixed sowing combination of annual ryegrass and white clover

[0014] Mixed sowing varieties: white clover (Haifa) + reed fescue (Duowei) + annual ryegrass (extra high);

[0015] Mixed sowing ratio: Mixed sowing of leguminous and gramineous forages, 30% of the single sowing amount of leguminous forage, and 70% of the single sowing amount of gramineous forage, specifically: the sowing amount of white clover per acre is 256 grams, The sowing rate of reed fescue is 1025 grams per mu, and the sowing rate of annual ryegrass is 220 grams per mu;

[0016] Sowing time: autumn sowing, at the end of August for areas above 800 meters above sea level, and in mid-September for areas below 800 meters above sea level;

[0017] Sowing method: remove debris on the ground, plow and prepare the ground, apply base fertilizer, farm organic fertilizer 2000kg / mu, drill, first sow gramineous pasture, cover soil 1cm, and then sow white clover, cover soil about 0.5cm, slope along the...

Embodiment 2

[0019] Example 2: Mixed sowing combination of annual ryegrass and red clover

[0020] Mixed sowing varieties: red clover (Wuxi red clover), reed fescue (Duowei) + duckweed (Amber), annual ryegrass (extra tall);

[0021] Mixed sowing ratio: mixed sowing of leguminous forage and gramineous forage, leguminous forage is 30% of the unicast sowing amount, gramineous forage is 70% of the unicast sowing amount, specifically: the sowing amount of red clover per acre is 400 grams, The sowing rate of reed fescue is 512 grams per mu, the sowing rate of duck grass is 512 grams per mu, and the annual ryegrass is 220 grams per mu;

[0022] Sowing time: Sowing in late February to early March in spring, planting in areas above 800m above sea level;

[0023] Sowing method: remove debris on the ground, plow and prepare the ground, apply base fertilizer, farm organic fertilizer 2000kg / mu, drill, first sow gramineous pasture, cover soil 1cm, then sow red clover, cover soil 0.5cm, slope along the ...

Embodiment 3

[0025] Embodiment 3: Mixed sowing combination of annual ryegrass and alfalfa

[0026] Mixed sowing varieties: alfalfa (tourist), reed fescue (Duowei), duckweed (Amber), annual ryegrass (extra tall);

[0027] Mixed sowing ratio: mixed sowing of leguminous and gramineous herbage, 30% of the sowing rate of leguminous herbage and 70% of the unicasting rate of gramineous herbage, specifically: the sowing rate of alfalfa is 337 grams per mu, and the sowing rate of reed The sowing rate of fescue fescue is 512 grams per mu, that of duck grass is 512 grams per mu, and that of annual ryegrass is 220 grams per mu;

[0028] Sowing time: autumn sowing, planting in areas below 800m above sea level;

Abstract

The invention relates to a method for mixedly sowing annual ryegrass and perennial grass, which is suitable for establishing artificial grassland in south, in particular to a method for establishing artificial grassland by introducing annual ryegrass onto perennial artificial grassland. The annual ryegrass and the perennial grass are mixedly sowed by a certain proportion. By utilizing the advantages of rapidly growing of the annual ryegrass, the cutting is performed at the right time, the grass yield in season is improved, and the height can be controlled by cutting. Therefore, the growth of the perennial grass can be ensured, the growth of the weeds is inhibited because of insufficient light, and then the weeds gradually disappear from the grass. The invention solves the problems of low grass yield of the artificial grassland established in the current year in south and heavy weeds, thereby being of great significance for popularizing artificial grassland growth in south and promoting the development of grassland agriculture in south.

Description

technical field [0001] The invention relates to the field of pasture planting, in particular to a method for mixing annual ryegrass and perennial pasture. Background technique [0002] Artificial grassland is newly built or improved grassland using agricultural technical measures. Its productivity is higher than that of natural grassland, and it is of great significance to reduce the loss of livestock due to insufficient forage in winter and spring, increase the yield and quality of livestock products, improve soil quality, prevent soil erosion, and improve land utilization. Therefore, the amount of artificial grassland area has become a symbol to measure the development level of grassland animal husbandry in a region or country. [0003] In recent years, due to the drought and frequent sandstorms in the north, the traditional northern grassland animal husbandry has been greatly impacted. The existing northern grasslands are difficult to support the growing number of lives...
