When the UV spectrophotometer determines that the initial ultramicronized polyenergy humic acid raw material solution does not begin to absorb light energy, irradiate the initial ultramicronized polyenergy humic acid raw material solution again according to the ultraviolet light wave wavelength until the UV spectrophotometer determines that the initial ultramicronized polyenergy humic acid raw material solution begins to absorb light energy;

[0134] Comparative Example 1:

[0135] Conduct an experiment on the composition of the soil without using the ultrafine particle energy - gathering humic acid soil conditioner to obtain the experimental results of the soil without using the ultrafine particle energy - gathering humic acid soil conditioner.

[0136] Conduct soil environment detection experiments on Examples 1 - 8 and Comparative Example 1 respectively. The experimental data are shown in Table 1:

[0137] Table 1

[0138]

[0139] In Table 1, when comparing Example 1 with Comparative Example 1, the proportion of micro - aggregates in the soil increased by 4.9 percentage points, indicating that after using the ultrafine particle energy - gathering humic acid soil conditioner, the problem of soil compaction was solved. When comparing Example 2 with Example 1, the proportion of micro - aggregates increased by 1 unit, indicating that by controlling the particle size of the coarse - crushed discharge and the particle size of the fine - crushed discharge, the soil compaction treatment effect of the ultrafine particle energy - gathering humic acid soil conditioner can be improved. The use effect of the ultrafine particle energy - gathering humic acid soil conditioner in Example 3 was slightly improved compared with that in Example 2, indicating that adding thermophilic bacterial agents to the formula to adapt to the high - temperature environment in desert areas can increase the environmental tolerance of the ultrafine particle energy - gathering humic acid soil conditioner. When comparing Example 4 with Example 5, the soil nutrient contents increased by 0.3, 3.6, and 20 units respectively, and the numbers of bacteria, actinomycetes, and fungi increased by 1.71, 1.49, and 1.13 units respectively, indicating that after adding organic fertilizers and inorganic fertilizers to the preparation formula of the ultrafine particle energy - gathering humic acid soil conditioner, the soil fertility was greatly improved. When comparing Example 8 with Example 5, it shows that by determining a specific wavelength for ultrafine particle activation, the use effect of the ultrafine particle energy - gathering humic acid soil conditioner can be improved.

[0140] Example 9:

[0141] Through the experiment on the application effect of the ultra-fine particle energy-concentrating humic acid soil conditioner on processing tomatoes, the processing tomato variety used in the experiment was Heinz No. 3402. 0.7 kg of ultra-fine particle energy-concentrating humic acid was spread per mu of land at a ratio of 1:1, and then the leaves were sprayed twice with a 2,500-fold liquid of soluble ultra-fine particle energy-concentrating humic acid. For the treatment with conventional fertilizer, 18 kg of diammonium phosphate was applied per mu of land, 25 kg of urea and 8 kg of potassium sulfate were applied per mu during the growth period. The experimental data of tomato planting are shown in Table 2:

[0142] Table 2

[0143]

[0144] As shown in Table 2, both the measured yield and the actual yield of tomatoes using the ultra-fine particle energy-concentrating humic acid soil conditioner are higher than those using conventional fertilizer.

[0145] Example 10:

[0146] Experiment on the application effect of the ultra-fine particle energy-concentrating humic acid soil conditioner on processing tomatoes. The processing tomato variety used in the experiment was Tunhe 5501. The experimental treatment results are shown in Table 3:

[0147] Table 3

[0148]

[0149] The effects of the ultra-fine particle energy-concentrating humic acid soil conditioner, organic fertilizer and chemical fertilizer on the yield of processing tomatoes are shown in Table 4:

[0150] Table 4

[0151]

[0152]

[0153] As shown in Table 4, under the same experimental conditions, the ultra-fine particle energy-concentrating humic acid soil conditioner did not cause a significant reduction in the yield of processing tomatoes. The use effect of the ultra-fine particle energy-concentrating humic acid soil conditioner is the same as that of organic fertilizer + chemical fertilizer, indicating that the ultra-fine particle energy-concentrating humic acid soil conditioner has a significant effect on reducing fertilizer amount and increasing efficiency. If the ultra-fine particle energy-concentrating humic acid soil conditioner and organic fertilizer + chemical fertilizer are applied together, the effect of increasing the yield and efficiency of processing tomatoes is significant.

[0154] Example 11:

[0155] An experiment on peppers was carried out using the soil improved with the ultra-fine particle energy-concentrating humic acid soil conditioner. The pigment pepper variety used in the experiment was Hongwan 13. The experimental data are shown in Table 5:

[0156] Table 5

[0157]

[0158] The effects of the ultrafine-particle energy-concentrating humic acid soil conditioner and organic fertilizer + chemical fertilizer on the yield of pigment peppers are shown in Table 6 as follows:

[0159] Table 6

[0160]

[0161] As shown in Table 6, under the same experimental conditions, the pepper population using the ultrafine-particle energy-concentrating humic acid soil conditioner grows uniformly and changes the progress of its growth period. The main factors for the yield increase are to increase the dry matter weight of a single pepper by 5.6% and the pepper-bearing ability by 4.5%. The ultrafine-particle energy-concentrating humic acid soil conditioner increases the pepper-bearing ability per unit area and the dry weight of a single fruit of peppers.

[0162] Example 12:

[0163] An experiment on wheat was carried out using the soil improved with the ultrafine-particle energy-concentrating humic acid soil conditioner. The wheat variety used in the experiment was Xindong 17. The experimental data are shown in Table 7 as follows:

[0164] Table 7

[0165]

[0166] The wheat variety was Xindong 17. Samples were collected at the seedling stage, tillering stage, jointing stage, heading stage, and filling stage of wheat to measure the dry matter weight. A total of 7 drip irrigations were carried out during the whole growth period, and the irrigation amount was 4500 m 3 ·hm-2. The plant height analysis of wheat at different growth stages under different treatments is shown in Table 8 as follows:

[0167] Table 8

[0168]

[0169] As can be seen from Table 8, the plant height of wheat at the seedling stage with only organic fertilizer applied alone is slightly higher than that of other treatments during the seedling stage and tillering stage of wheat. However, as wheat grows, the plant height of the treatment with the ultrafine-particle energy-concentrating humic acid soil conditioner + organic fertilizer applied at the jointing stage and heading stage is significantly higher than that with only organic fertilizer applied alone. The dry matter weight analysis of wheat at different growth stages under different treatments is shown in Table 9 as follows:

[0170] Table 9

[0171]

[0172] As can be seen from Table 9, regarding the changes in the dry matter weight per unit area of wheat under different treatments at each growth stage, when applying the ultrafine particle energy-gathering humic acid soil conditioner, the changes in the dry matter weight of wheat at each growth stage in the treatment of ultrafine particle energy-gathering humic acid soil conditioner + organic fertilizer + chemical fertilizer are not very obvious. There is an increase at the tillering stage and the heading stage. The comparison of soil bulk density of wheat at each growth stage under different treatments is shown in Table 10:

[0173] Table 10

[0174]

[0175] As can be seen from Table 10, at the tillering stage, the soil bulk density of each treatment has increased to varying degrees. For the treatments applying the ultrafine particle energy-gathering humic acid soil conditioner and adding organic fertilizer, the soil bulk density has increased. The analysis of wheat yield and yield components under different treatments is shown in Table 11:

[0176] Table 11

[0177]

[0178] Table 12

[0179]

[0180] As can be seen from Table 11 and Table 12, for the wheat treated with the ultrafine particle energy-gathering humic acid soil conditioner, the number of grains per spike, 1000-grain weight and yield have increased by 16.5%, 25.3% and 37.4% compared with the organic fertilizer treatment. The 1000-grain weight and yield have increased by 22.9% and 16.8% compared with the treatment of ultrafine particle energy-gathering humic acid soil conditioner + organic fertilizer.
