A preparation method of a plant nutrient medium is characterized by comprising the following steps:
s1, exposing and killing insects on herbaceous soil, coal, crushed corn straws, wheat bran, rice hulls, perlite, vermiculite and river sand, and fully and uniformly mixing to obtain a material (1);
s2, dissolving chitosan oligosaccharide in water to obtain a chitosan oligosaccharide solution;
s3, uniformly spraying the chitosan oligosaccharide solution on the surface of the material (1), and airing to form a material (2);
and S4, mixing the material (2) with the rest of other raw materials to obtain the plant nutrient medium.
As a further technical scheme, the mass ratio of the chitosan oligosaccharide to the water in the step S2 is 1.
A plant nutrient substrate is applied to potted plants, and the plant nutrient substrate and soil are uniformly mixed according to the mass ratio of 1:1.
The working principle and the beneficial effects of the invention are as follows:
1. the invention provides a potted plant nutrient medium which comprises herbaceous peat, wheat bran, rice hulls, crushed corn straws, weathered coal/lignite, perlite, vermiculite, river sand, fertilizer nutrients, vitamin bags, trace element bags, a water-retaining agent, crushed pyrethrum plants and chitosan oligosaccharide, and is obtained by fully and uniformly mixing the materials. The plant nutrient medium has simple process in the preparation process, convenient operation, low energy consumption in industrial production and reduced production cost.
2. Compared with other plant nutrient substrates, the plant nutrient substrate prepared by the invention is different from other plant nutrient substrates in that the pesticide and the bactericide are directly added into the formula, and the formula is changed into the formula which is added with pyrethrum plant fragments (including flowers, stems and leaves of pyrethrum) and chitosan oligosaccharide. The addition of pyrethrum plant fragments (including flowers, stems and leaves of pyrethrum) not only achieves the effects of expelling insects and killing insects, but also gradually decays and degrades in the nutrient medium to increase the content of organic matters, and is safer than the addition of pesticide type insecticide (bactericide) in the use process of the family plant nutrient medium. And chitosan oligosaccharide is added to change microbial flora in the nutrient medium and promote the growth of beneficial microorganisms, and can induce disease resistance of plants and generate immunity and killing effect on various fungi, bacteria and viruses. The matching application of the pyrethrum plant pieces and the chitosan oligosaccharide not only has the functions of expelling parasites and sterilizing, but also improves the stress (disease) resistance of the plants. The combination and matching of the pyrethrum plant fragments and the chitosan oligosaccharide replaces the function of pesticide (bacteria) in the nutrient medium, and is safer to human and environment in home gardening.
3. The quick-acting humic acid and the stable potential humic acid are matched and applied, so that the quick-acting humic acid is quickly utilized by plants, the growth of plant roots is promoted, and the survival rate of plant transplantation is improved. And secondly, the addition of the weathered coal/lignite is equivalent to the addition of macromolecular substances with relatively stable properties, and in the plant growth process, factors such as the alternate change of the dryness and the wetness of a nutrient substrate, the activity of microorganisms and the like can cause the degradation of the macromolecular weathered coal/lignite, so that the macromolecular weathered coal/lignite is converted into humic acid micromolecules which can be utilized by plants. In addition, the addition of the chitosan oligosaccharide in the formula promotes the growth of crop roots, increases root secretions and promotes the decomposition of weathered coal/lignite, so that the weathered coal/lignite is slowly converted into utilizable humic acid, the aim of providing humic acid nutrients for plant growth for a long time is fulfilled, and meanwhile, the rationalization and resource utilization of the weathered coal/lignite low-rank coal are realized.
4. The potted plant nutrient medium prepared by the invention has the following characteristics: (1) The quick-acting nutrients and the slow-release nutrients act together, so that the fertilizer supply time is long. (2) The quick-acting humic acid is combined with the phosphorus element, so that the root system of the transplanted plant can be recovered quickly, and the growth of the root system of the plant can be promoted better. (3) The microelement and the compound vitamin are added, so that the supply of the nutrient medium to the plant microelement is ensured, and the compound vitamin plays a role in enhancing the stress resistance of the crops. (4) The pyrethrum plant pieces (including flowers, stems and leaves of pyrethrum) are added to achieve the effect of expelling and killing the insect bacteria, and the insecticidal composition is safer on potted plants in the courtyard than the insecticidal (bacterial) composition added with pesticide. (5) During the use process, the chitosan oligosaccharide can change microbial flora in the nutrient substrate, promote the growth of beneficial microorganisms, induce the disease resistance of plants, generate immunity and killing effect on various fungi, bacteria and viruses and improve the stress (disease) resistance of potted plants.

The test process comprises the following steps: 600g of plant nutrient medium is put into a flowerpot, 4 corn seeds are planted, 300g of plant nutrient medium is watered in each flowerpot every 7 days, each treatment is repeated for 5 times, and the culture time is 45 days. After the cultivation is finished, the contents of organic matters and humic acid in the plant nutrient media and the indexes of single plant biomass, plant height, stem thickness and root system weight of the corn crops in the example 1 and the example 2 and the corresponding control groups are respectively measured, and the results are shown in tables 3 and 4.
Determination of organic matter:
the determination method is a potassium dichromate volumetric method, and the specific principle is that organic carbon in the organic fertilizer is oxidized by using a quantitative potassium dichromate-sulfuric acid solution under the heating condition, the redundant potassium dichromate solution is titrated by using a ferrous sulfate standard solution, and meanwhile, a blank test is carried out by using silicon dioxide as an additive. And calculating the organic carbon content according to the consumption of the oxidant before and after oxidation, and multiplying the organic carbon content by a coefficient 1.724 to obtain the organic matter content. (Standard NY/T525-2021)
Determination of humic acid:
the determination method is a volumetric method, and specifically comprises the steps of extracting humic acid from a coal sample by using sodium pyrophosphate alkali liquor or sodium hydroxide solution, oxidizing carbon in the humic acid into carbon dioxide by using potassium dichromate in strong acid solution, and calculating the yield of the humic acid according to the consumption of the potassium dichromate and the carbon content ratio of the humic acid. (Standard GB/T11957-2001)

Table 5 results of measurement in example 2
As can be seen from tables 4 and 5, after 45 days of culture, the content of humic acid in the plant nutrient substrate which is treated by adding chitosan oligosaccharide is improved by 1.04 percent and 0.94 percent compared with the plant nutrient substrate which is not treated by adding chitosan oligosaccharide, and the increase rate of humic acid is 5.28 percent and 5.68 percent. The corn planted by the plant nutrient medium which is added with the chitosan oligosaccharide and not added with the chitosan oligosaccharide has obvious influence on the biomass, stem thickness and root weight of a single plant, and is respectively improved by 13.46 percent and 9.30 percent, 6.43 percent and 5.60 percent, 9.40 percent and 8.82 percent. The long-time cultivation and the influence of conditions such as water and the like show that the chitosan oligosaccharide added into the plant nutrient medium can promote the growth of crop roots, increase root secretions, promote the decomposition of weathered coal/lignite, increase the content of humic acid and promote the growth of crops.
