Embodiment 1

[0019] A restoration method for dominant plants in degraded grasslands is mainly used in the typical Inner Mongolian grassland, which is located in Maodeng Pasture, Xilinhot City, Inner Mongolia Autonomous Region. Wild leek composition.

[0020] The restoration method promotes the restoration of the dominant plants in the degraded grassland by grazing sheep in different periods; the restoration method is: during the grazing period from June to August of that year, the grazing time of the sheep every day is from 7:30 am to 12:30 am. :00 end; the grazing density in the grazing stage from June to August of the current year is 2.5 sheep units / ha, and after the grazing ends, feed supplementation is carried out for the flock; in the grazing stage from September to next March, every day The grazing time of the flock is from 13:00 p.m. to 17:00 p.m.; the grazing density during the grazing period from September of the current year to March of the following year is 1.0 sheep units / ha, a...

Embodiment 2

[0031] The difference between this example and Example 1 is that in this example, the grazing density during the grazing period from June to August of that year was 3 sheep units / ha, and feed supplementation was carried out for the sheep after the grazing ended; The grazing density in the grazing period from September to March of the following year is 1.5 sheep units / ha, and the supplementary feeding amount in the grazing period from June to August in the current year is 100g / cow. The amount of feed supplementation in the grazing stage from September of the current year to March of the next year is 200g / only.

[0032] The present embodiment has the following effects: compared with traditional all-day grazing, the technical scheme provided by embodiment 2 makes pasture pasture hay output be 132.4g / m 2 (Table 3), compared with whole-day grazing, it has improved by 65.3%, and at the same time, the grazing pressure of the whole pasture is reduced by more than 45%.

[0033] Table ...

Embodiment 3

[0036] The difference between this embodiment and Example 1 is that in this embodiment, the grazing density during the grazing period from June to August of that year was 3.5 sheep units / hectare, and feed supplementary feeding was carried out for the flock after the grazing ended; The grazing density in the grazing period from September of the current year to March of the following year is 2.0 sheep units / ha. The amount of feed supplementary feeding in the grazing stage from June to August of that year is 150g / only. The amount of feed supplementation in the grazing stage from September of the current year to March of the next year is 300g / only.

[0037] The present embodiment has the following effects: compared with the technical scheme of traditional all-day grazing, the technical scheme of the present embodiment makes pasture hay output of grazing field be 113.3g / m 2 (Table 4), compared with whole-day grazing, it has improved by 41.4%, and the grazing pressure of the whole ...

Abstract

The invention relates to a restoration method for degraded grassland dominant plants, belonging to the technical field of grassland grazing. The restoration method of the invention is used for typical grasslands in Inner Mongolia, and the restoration method promotes restoration of dominant plants in degraded grasslands by grazing sheep in different periods of time; the method is suitable for typical grasslands in Inner Mongolia, and can realize Leymus chinensis, the dominant plants in degraded grasslands in typical grasslands and the repair of Cinnamon japonica. The method can effectively coordinate the balance between grazing and grassland restoration, and achieve restoration of grassland plants and stabilize the diversity of grassland species on the premise of ensuring the production quality and yield of grassland animal husbandry. In addition, the method is simple and easy to implement, and is suitable for use by many herdsmen.

Description

technical field [0001] The invention relates to a restoration method for dominant plants in degraded grasslands, and belongs to the technical field of grassland grazing. Background technique [0002] Herbivorous livestock are important determinants of grassland plant community composition and growth. In a grassland ecosystem, the composition of a balanced and stable plant community depends to a large extent on the grazing activities of herbivorous livestock, such as foraging, trampling, and excretion of feces and urine, which have an impact on the plant community (Newman et al., Optimal diet selection by generalist grazing herbivore. Function Ecology, 1995, 9:255-268). As an intersection point on the production interface of animals and plants, feeding behavior is the most direct factor affecting the structure and growth of plant communities, and the core issue is feeding habits selection. Food choice is an effective choice made by domestic animals in order to meet the nutr...
