Description
Technical Field
The invention relates to the field of human life necessities, in particular to a culture medium.
Background
The plant tissue culture technology is a new technology developed by modern biological science, is a main component of biotechnology (namely bioengineering), and is mass production carried out in an ultra-clean tissue culture room for rapid propagation and detoxification, namely an industrialized cultivation room. Totipotency of plant cells was proposed since haberlandt (g.haberlandt)1902, that is, the own cell or sexual cell of each plant has a complete set of genetic genes of the plant, so that each cell can develop into a plant identical to the mother under certain culture conditions. This concept, although it was proposed in the beginning of the last century, is not practically possible under the current technological conditions. Over 80 years of efforts of countless scientists, the tissue culture technology is continuously improved, the technology tends to be perfect and mature, and the totipotency of the cells is completely verified in theory at present, and a foundation is laid for the practical application of the tissue culture. Plant tissue culture has been flowering throughout the world and has progressed rapidly around the world.
The culture medium for flower planting in the prior art is poor in flower growth effect, fertilization, insect killing and sterilization are carried out continuously in the flower growth process, along with the use of chemicals by people, firstly, the environment is easy to pollute to change soil, secondly, medicine residues are easy to accumulate on plants, so that people seek green environment protection, pollution-free and additive-free green plant vegetables more and more at present, and the quality of the culture medium plays a vital role in the growth of flowers.
Disclosure of Invention
The invention aims to solve the problem that an innovative scheme is provided aiming at the defects in the prior art, in particular to a culture substrate which can slowly release nutrients and has an inhibiting effect on plant pathogenic bacteria.
In order to solve the problems, the invention adopts the following scheme: a novel flower culture medium comprises the following components: expanded perlite, vermiculite, potassium feldspar powder, ground phosphate rock and peat soil, and is characterized by also comprising any one or more of artemisia desertorum seed powder, nitraria seed shell particles, oleaster kernel particles and scutellaria baicalensis dreg powder.
Further, the novel flower culture medium is characterized in that the nitraria seed shell particles, the oleaster kernel particles and/or the scutellaria root dreg powder account for 30-40% of the total mass of the medium.
Furthermore, the novel flower culture medium is characterized in that the nitraria seed shell particles are prepared by crushing byproducts of nitraria seed after nitraria seed is extracted to prepare nitraria seed oil and nitraria flavone, and the particle size of the particles is 0.5-1.5 mm.
Furthermore, the novel flower culture medium is characterized in that the oleaster seed particles are prepared by crushing byproducts of oleaster seed extracted with oleaster oil and oleaster flavone, and the particle size of the particles is 1-3 mm.
Furthermore, the novel flower culture medium is characterized in that the artemisia desertorum seed powder is prepared by grinding artemisia desertorum seed peels and then sieving the seeds through a 40-mesh sieve.
Further, the novel flower culture medium is characterized in that the scutellaria drug residue powder is a byproduct after baicalin is extracted from scutellaria ultra-fine powder.
The invention has the following technical effects: the sand sagebrush seed powder has the main effects that the sand sagebrush polysaccharide contained in the powder has good water absorption and retention effects, and meanwhile, the viscous crosslinking effect generated after the sand sagebrush polysaccharide absorbs water can promote the formation of a soil aggregate structure, so that the water retention capacity and the water buffering capacity of soil are improved. Therefore, the matrix is more suitable for cultivating the flower plants sensitive to the soil moisture condition, and the physiological plant diseases caused by improper watering can be prevented.
The white thorn seed shell particles, the oleaster kernel particles and the scutellaria baicalensis dreg powder have the following effects: on one hand, the nitraria seed shell particles and the narrow-leaved oleaster kernel particles can increase the porosity and air permeability of soil and serve as important components of soil organic matters; on the other hand, the three raw materials contain bacteriostatic substances with different bacteriostatic spectrums, and the combination of the three raw materials can generate broad-spectrum inhibitory effect on plant pathogenic bacteria possibly existing in the matrix, thereby preventing plant diseases; finally, the nitraria seed shell particles and the narrow-leaved oleaster kernel particles both contain organic acid with soil pH value buffering effect, so that the pH value of the matrix is weakly acidic. Most flowers are suitable for growing in slightly acidic soil environment, so the flower substrate is particularly suitable for cultivating the flowers.
The expanded perlite and the vermiculite in the matrix have the characteristics of looseness and air permeability, and the nitraria seed shell particles and the oleaster kernel particles can increase the looseness, the air permeability and the water retention capacity of the soil.
The pH value of the substrate is about 6 (slightly acidic), and the substrate is suitable for the cultivation of most of flower plants. Flavonoid compounds contained in the nitraria seed husks and the oleaster pits and baicalin contained in the scutellaria drug residue powder have broad-spectrum bacteriostatic effects, can inhibit various plant pathogenic bacteria, and the nitraria seed husks, the oleaster pits and the scutellaria drug residue powder provide the baicalin with a bacteriostatic action, and can play a role in preventing flower diseases. The potassium feldspar powder and the phosphate rock powder in the matrix can slowly release medium and trace elements necessary for various flowers such as phosphorus, potassium, calcium, silicon, magnesium, zinc, iron and the like for a long time under the condition of the pH value of the matrix; and the pH value of the substrate can be buffered, and the effect of preventing the substrate from being excessively acidified in the flower cultivation process can be achieved.
The matrix formed by the invention is loose and breathable, has rich and comprehensive plant nutrient components and can be slowly released, can stably supply nutrient substances required by plant growth for a long time, and simultaneously has excellent water retention performance and uniform water supply characteristic. The substrate also contains various natural plant bacteriostatic components, and has strong effects of inhibiting plant pathogenic bacteria and preventing plant diseases.
The matrix development of the invention expands the application range of the byproduct (waste) of deep processing of nitraria tangutorum bobr, narrow-leaved oleaster and scutellaria baicalensis, reduces the generation of organic solid waste in the processing process, and improves economic benefit and ecological environmental benefit.
