Description

Technical Field

[0001] The present invention relates to the technical field of cosmetics, and in particular to an organic nutrient soil and a preparation method thereof. Background Art

[0002] With the acceleration of urbanization and the vigorous development of the horticultural and flower industry, the demand for high-quality soil is increasing. Traditional soils often have problems such as insufficient fertility, poor air permeability, and weak water retention, which are difficult to meet the diverse needs of plant growth. Organic nutrient soil can provide plants with rich nutrients, good physical structure and biologically active environment, which helps to promote the healthy growth of plants, improve stress resistance and ornamental value. However, the existing organic nutrient soil still has many shortcomings in formula and production process, such as unbalanced nutrients, complex production process, and high cost. Therefore, it is of great practical significance to develop an organic nutrient soil that is comprehensive in nutrition, easy to make and low in cost.

[0003] Currently, no effective solution has been proposed for the problems in the related technologies. Summary of the invention

[0008] As a further solution of the present invention, the leaf mold is taken from rotten leaves piled up under a pine forest and is used after preliminary screening to remove impurities.

[0009] As a further solution of the present invention, the fiber length of the peat soil is 1-5 mm, and the pH value is between 4.5-5.5.

[0010] As a further embodiment of the present invention, the particle size of the perlite is 2-4 mm mesh.

[0011] As a further solution of the present invention, the expansion multiple of the vermiculite is 8-10.

[0012] As a further embodiment of the present invention, the raw materials of the organic fertilizer include but are not limited to animal manure, plant straw, cake residue, etc., which are subjected to high-temperature composting fermentation treatment. The temperature, humidity and ventilation conditions are controlled during the fermentation process to ensure that the organic fertilizer is fully decomposed and has no odor and no residual bacteria or insect eggs.

[0013] As a further embodiment of the present invention, the effective viable count of beneficial microorganisms in the biological agent is not less than 2×10 8 CFU / g.

[0014] As a further solution of the present invention, the following steps are included:

[0015] Step 1: Raw material preparation, collect the above-mentioned leaf mold, peat soil, perlite, vermiculite, organic fertilizer and biological agent in parts by weight, and ensure that the quality of each raw material meets the requirements;

[0016] Step 2: Raw material pretreatment, (1) crushing the leaf mold to make its particles uniform in size; (2) drying or drying the peat soil to remove excess water and adjust its water content to 30-35%; (3) screening perlite and vermiculite to remove dust and oversized particles to ensure that their particle size meets the requirements; (4) crushing the organic fertilizer to refine its particle size;

[0017] Step 3: Mix and stir. Add the pretreated leaf mold, peat soil, perlite, vermiculite and organic fertilizer into the mixer in turn, stir evenly for 15 minutes, then sprinkle the biological agent evenly on the surface of the mixed material and stir again for 10 minutes.

[0018] Step 4: Composting and fermentation: the mixed materials are piled into a trapezoidal pile with a height of 1.5m and a width of 2m. Plastic film is covered on the pile to keep it warm and moist. The pile is turned every 7 days. The fermentation process lasts for 45 days.

[0019] Step 5: Post-processing: the organic nutrient soil after fermentation is air-dried or air-dried to reduce its moisture content to 20-25%, and then screened to remove lumps and impurities that are not completely decomposed to obtain the finished organic nutrient soil, which is packaged for storage or direct use.

[0020] Beneficial effects of the present invention

[0078] Experimental example:

[0079] Several tomato seedlings with similar growth conditions were selected and randomly divided into 5 groups, and planted in the nutrient soil prepared in Example 1, Example 2, Comparative Example 1, Comparative Example 2 and ordinary garden soil (control group), respectively. Cultivation experiments were carried out under the same environmental conditions (light, temperature, humidity, watering and fertilization management, etc.), and the growth indicators of the tomato plants (plant height, stem thickness, number of leaves, flowering and fruiting time, fruit yield and quality, etc.) were observed and recorded.

[0080] The test results show that the tomato plants planted in the organic nutrient soil of Example 1 and Example 2 grow vigorously, and the plant height, stem thickness, and leaf number are significantly higher than those of Comparative Example 1, Comparative Example 2, and the control group; the flowering and fruiting time is advanced by 3-5 days, the fruit yield is increased by 20-30%, and the fruit quality (taste, sugar content, vitamin C content, etc.) is also significantly better than other groups. Comparative Example 1 has certain advantages in plant growth in the short term due to the use of chemical fertilizers, but later phenomena such as soil compaction and poor plant growth occur; Comparative Example 2 does not add biological agents and is not fermented, the nutrients in the nutrient soil are released slowly, the microbial activity is low, and the promotion effect on plant growth is limited.
