[0052] Comparative Example 4: The difference between this comparative example and Example 1 is that the additive is not contained in this comparative example.

[0053] Performance test: The organic fertilizers prepared in Example 1, Example 2, Example 3, Comparative Example 1, Comparative Example 2, Comparative Example 3 and Comparative Example 4 are subjected to performance tests, and the obtained test data are recorded in the following table:

[0054] In the performance test, multiple apple tree test fields with an area of 1 mu are selected. The planting varieties and planting densities of the apple tree test fields are the same. The double-component organic fertilizers containing probiotics prepared in Example 1, Example 2, Example 3, Comparative Example 1, Comparative Example 2, Comparative Example 3 and Comparative Example 4 are respectively used for fertilization on multiple test fields, and the average single-plant yield and mu yield are recorded after harvesting.

[0055] It can be seen that the per-plant yield performance and mu-yield performance of the organic fertilizers prepared in Comparative Examples 1, 2, 3, and 4 are lower than those in Examples 1, 2, and 3. This shows that: in the preparation of organic fertilizers, after the cow dung undergoes two composting and fermentation treatments, it can promote the decomposition of cellulose, improve the humification efficiency. By adding sawdust and rice husk powder, it can regulate the porosity and enhance the air permeability. After the humic acid undergoes citric acid activation treatment, it can chelate trace elements in the soil and improve the absorption rate of nutrients by plant roots. Using its porous structure, diatomite can act as a carrier to play a role in slow-release of nutrients, enabling the plant roots to effectively and stably receive the nutrient supply of the organic fertilizer for a long time, thereby improving the production efficiency of plants and achieving the purpose of increasing production. By using the solid material and the liquid material in combination, after the solid material completes fertilization, the nutrient elements are slowly released in the soil. After the liquid material is used, it can transport the active bacteria group to the position of the plant roots through water, quickly respond to complete the nutrient supply to the plant roots. The pores of diatomite can provide colonization sites for lactic acid bacteria and bacillus in the liquid material, forming an effective load structure, further improving the absorption rate of nutrients by plant roots.

[0056] By comparing and analyzing the relevant data in the table, it can be seen that the organic fertilizer prepared by the present invention not only has good per-plant yield performance, but also has excellent mu-yield performance. This shows that the two-component organic fertilizer containing probiotics provided by the present invention has a broader market prospect and is more suitable for promotion.
