Description

Technical Field

[0001] The invention belongs to the technical field of soil conditioners, and in particular relates to a conditioner for regulating the pH value of organic soil. Background Art

[0002] In the field of agricultural production and horticulture, the pH of organic soil plays a vital role in the growth and development of plants. Appropriate soil pH can provide a good growth environment for plants and promote the absorption and utilization of nutrients. However, due to the influence of natural factors and human activities, the pH of organic soil often changes. Overly acidic or overly alkaline soils will have an adverse effect on plant growth. At present, the common soil pH regulators on the market mainly include lime, gypsum, sulfur, etc. However, the regulating effects of lime and gypsum are relatively simple and easily lead to soil compaction; the amount of sulfur used is difficult to control, and excessive use may cause pollution to the soil and the environment. In addition, these traditional regulators often cannot meet the specific needs of different plants for soil pH. Summary of the invention

After stirring for a while, pause and observe the uniformity of the mixture. Repeat the stirring several times until the three substances are completely and evenly mixed.

[0012] The specific preparation steps of the Chinese medicine residue include: Select hawthorn, tangerine peel and black plum and place them in the medicine pot; Pour clean water and heat until boiling for 5 minutes; After the Chinese medicine is collected, the residues after processing hawthorn, tangerine peel and black plum are obtained, and the Chinese medicine residue is obtained after mixing.

[0013] The beneficial effects of the present invention are as follows: the regulator for regulating the pH value of organic soil can improve the conduction efficiency of the alkali regulator with the help of bamboo fiber filaments, soybean fiber filaments and carbon fiber filaments, so that the regulator is conducted along a specific path and accurately reaches the area where the pH value needs to be adjusted, so that the acid-base regulator can play a more full role, improve its utilization rate, reduce the waste of regulators caused by uneven diffusion or loss, and reduce the regulation cost. Compared with the prior art, the regulator of the present invention has obvious advantages in regulating the pH value of organic soil, and provides an effective soil improvement solution for agricultural production and horticulture.

[0034] 3. According to "Soil Testing Part 6: Determination of Soil Organic Matter" (NY / T1121.6-2006), the organic matter content change of the organic soil conditioned by the conditioning agent prepared by Examples 1-3 and Comparative Examples 1-3 was tested.

[0035] According to the "Soil Total Nitrogen Determination Method (Semi-micro Kelvin Method)" (NY / T53-1987), the total nitrogen content of the organic soil conditioned by the conditioners prepared by Examples 1-3 and Comparative Examples 1-3 was tested.

[0036] According to the "Soil Total Phosphorus Determination Method" (NY / T88-1988), the total phosphorus content of the organic soil conditioned by the conditioners prepared by Examples 1-3 and Comparative Examples 1-3 was tested.

[0037] According to the "Soil Total Potassium Determination Method" (NY / T88-1988), the total phosphorus content of the organic soil conditioned by the conditioners prepared by Examples 1-3 and Comparative Examples 1-3 was tested.

[0038] According to "Soil Testing Part 21: Determination of Maximum Moisture Absorption of Soil" (NY / T1121.21-2008), the water retention of organic soil conditioned by the conditioning agents prepared in Examples 1-3 and Comparative Examples 1-3 was tested. At the same time, the fertility, air permeability, water retention and other indicators of the conditioned soil can also be tested to comprehensively evaluate the performance of the conditioner; It should be noted that the experimental test requires the collection of organic soil 30 days after it is put into the planting site; Table 1 project Organic matter content (%) Nitrogen content (ppm) Phosphorus content (ppm) Potassium content (ppm) Example 1 15.2 16.5 18.3 13.8 Example 2 120 135 150 105 Example 3 80 90 100 70 Comparative Example 1 100 110 120 85 Comparative Example 2 15.2 16.5 18.3 13.8 Comparative Example 3 120 135 150 105 From the test results, we can see that: According to the organic soils prepared in Examples 1-3 and Comparative Examples 1-3, the organic matter content (%), nitrogen content (ppm), phosphorus content (ppm), and potassium content (ppm) in the organic soil prepared in Example 3 are optimal. The conductive fiber silk can improve the conduction efficiency of the regulator, thereby improving the nutrient supply of the soil and improving the soil ecological environment.

[0039] 4. According to "Determination of Soil pH" (NY / T1377-2007), the pH value of the organic soil adjusted by the regulator prepared by Examples 1-3 and Comparative Examples 1-3 was tested; Table 2 project pH Example 1 6.7 Example 2 6.7 Example 3 6.7 Comparative Example 1 6.7 Comparative Example 2 6.7 Comparative Example 3 6.7 The test results show that: According to the organic soil prepared in Examples 1-3 and Comparative Examples 1-3, the pH value of Example 3 is 7.1, which is closest to neutrality. The pH value of the comparative group is relatively acidic, and there is a certain gap compared with the example group. It is known that the mixed use of conductive fiber filaments and their composition ratio have an important influence on the regulating effect of the regulator. In Example 3, a mixed conductive fiber filament of bamboo fiber filaments, soybean fiber filaments and carbon fiber filaments in a mass ratio of 2:1:1 is used, and its regulating effect is the best, while Comparative Examples 1 and 2 only use single bamboo fiber filaments and soybean fiber filaments, respectively, and Comparative Example 3 does not contain conductive fiber filaments, and its regulating effect is not as good as that of Example 1, Example 2, and Example 3.

Bamboo fiber has good water absorption and air permeability, and can promote the circulation of water and air in the soil. Soybean fiber contains rich protein and amino acids, which can provide nutrients for microorganisms in the soil, promote the activity of microorganisms, and thus improve the soil structure. Carbon fiber has high strength and high conductivity, which can enhance the stability and conductivity of the regulator.

[0042] VI.
