[0043] Step five: soil turning and fertilizing: turning the soil in the sub-areas, and respectively fertilizing;
[0044] Step six: partition fence: the fence device is arranged in the subzone after fertilization, the fence device can be inserted into the soil to a certain depth, the fence device is arranged in a rectangular shape, and the fence device can separate the tail of the fence device from the soil outside;
[0045] Step seven: multi-point sampling: multi-point sampling of soil in each subzone;
[0046] Step eight: index calculation: plant function is calculated, and the benefits of key technologies for synergistic repair and ecological multi-function improvement are evaluated. In the field area, an area with uniform species composition is selected and divided into large areas, small areas and subareas. Different shrub-grass configuration combinations (different livestock combinations for grazing) are used in each large area. The small areas in the large area are separated to avoid mutual influence. Subareas are set in each small area. Different fertilization methods are set in the subareas. The small areas in each large area are used as mutual controls. Then, the effects of shrub-grass configuration combinations on the ecological system are quantified under various fertilization methods and various shrub-grass configurations. Then, the most beneficial scheme for ecological environment repair and economic benefits of livestock grazing is obtained. Through the combination with local farmers' lives, the environment is repaired, and the wind and sand prevention and control ability of grassland desertification land is improved, which greatly improves the environment.
[0047] The six large areas are horse-cattle-sheep-camel mixed grazing area, horse single grazing area, cattle-sheep mixed grazing area, summer grazing and winter grazing area, sheep single grazing area and perennial enclosure area.

The four subareas are not fertilized, fertilized with organic fertilizer and chemical fertilizer, applied rhizosphere growth promoting bacteria, and applied biochar-bacteria agent complex. The three small areas are arranged in a diagonal line in the large area, so that the distance between each small area and the small area in the adjacent large area is also far away, avoiding the influence. At the same time, the distance between the four subareas in each small area is far away, which can avoid the influence caused by different fertilizers.
[0049] When fertilizing the subplots, turn over the soil in the three subplots where organic fertilizer and chemical fertilizer are applied, rhizosphere growth promoting bacteria are applied, and biochar-bacteria complex is applied, and fertilize according to the fertilization method of the three fertilizers.

Rhizosphere growth promoting bacteria are applied near the seed roots during seed turning and fertilization. When turning and fertilizing, the range is larger than the sub-plot range. After fertilization, the fence device is driven into the turned land. The larger turning range ensures that each part of the area enclosed by the fence device (i.e. the sub-plot area) is fully turned and fertilized.
