[0148] Comparative Example 1:

[0149] Conduct experiments on the composition of the soil without using the soil biological conditioner to obtain the experimental results of the soil without using the soil biological conditioner.

[0150] Specifically, soil environment detection experiments were conducted on Examples 1-5 and Comparative Example 1 respectively, and the experimental data are shown in Table 1:

[0151] Table 1

[0152]

[0153] In Table 1, the units of each index are as follows: the number of bacteria is cfu / g×10 6 , the number of actinomycetes is cfu / g×10 5 , the number of fungi is cfu / g×10 3 , urease is mg, sucrase is mg, and catalase is ml. The numbers of soil bacteria, actinomycetes and fungi can reflect the improvement of material cycling ability and the degree of increased diversity, and soil enzyme activity is an important indicator to measure soil fertility.

[0154] From the above experimental data, it can be concluded that by comparing Example 1 with Comparative Example 1, it is found that there is a multiple increase in the numbers of soil bacteria, actinomycetes, fungi and various enzymes, indicating that the soil fertility and material cycling ability in the high-altitude area have been greatly improved after using the soil biological conditioner. By comparing Example 2 with Example 1, the number of bacteria increases by 1.1 units. Thus, it can be concluded that in terms of the formula, after adding other additives, the conditioner greatly improves the soil material cycling ability. By comparing Examples 2, 3 and 4, it is found that the differences in various indicators are not obvious. Thus, it can be concluded that in terms of the formula, due to insufficient local production, the conditioner prepared by the adjusted formula ratio and the best formula ratio has little difference in various usage effects. By comparing Example 5 with Example 4, the number of actinomycetes increases by 0.88 units. Thus, it can be concluded that during the preparation process, after adding the analysis and improvement of the antagonistic effect level of the sampling quality inspection microbial inoculum and improving the process, the material cycling ability of the soil biological conditioner is improved again. By comparing Example 6 with Example 5, the sucrase increases by 0.95 units. Thus, it can be concluded that during the preparation process, after adding the analysis and improvement of the antagonistic effect level of the sampling quality inspection conditioner and improving the process, and then adding the analysis and treatment method of the nitrogen fixation efficiency of the nitrogen-fixing bacteria agent in the soil biological conditioner under special environments such as low temperature and low oxygen, the soil fertility of the soil biological conditioner is ensured to be improved.
