Description

Technical Field

[0001] The invention belongs to the field of liquid fertilizers, in particular to a method for using lincomycin finished liquid fertilizer to promote bright colors of flowers. Background Art

[0002] Liquid compound fertilizer (Fluid Fertilizer), also known as fluid compound fertilizer, commonly known as liquid fertilizer, is a liquid product containing two or more nutrients required by crops. These nutrients are dissolved in water as solutes to form a solution or suspended in water with the help of a suspending agent to form a suspended paste. Liquid fertilizers have been developed to date and there are many varieties, which can be roughly divided into two categories: liquid nitrogen fertilizer and liquid compound fertilizer. Among them, the effective substances of liquid nitrogen fertilizer include ammonium, nitrate and amide nitrogen, such as liquid ammonia, ammonia water, and nitrogen solution. Liquid compound fertilizer contains all the nutrients required for plant growth, such as nitrogen, phosphorus, potassium, calcium, magnesium, sulfur and trace elements, and can also be added with organic substances soluble in water (such as humic acid, amino acids, plant growth regulators, etc.). Liquid compound fertilizer can be designed according to the nutritional requirements of crop growth. The fertilizer formula can be adjusted at any time according to the different growth of crops. Scientific formulas can significantly improve fertilizer utilization. The fertilizer efficiency of liquid fertilizers is usually more than 30% higher than that of conventional compound fertilizers.

[0003] Lincomycin acts on the 50S subunit of the ribosome of sensitive bacteria, inhibiting the protein synthesis of bacterial cells by preventing the extension of the peptide chain. It is generally an antibacterial agent, but at high concentrations, it also has a bactericidal effect on highly sensitive bacteria.

[0004] In the prior art, liquid fertilizer has the following problems: The ratio of nitrogen, phosphorus and potassium required by plants during flowering is different from that during growth stages. If the ratio of nitrogen, phosphorus and potassium in liquid fertilizer does not meet the needs of plants during flowering, it may lead to insufficient or excessive nutrient supply.

[0005] In addition to nitrogen, phosphorus and potassium, plants also need a variety of trace elements to maintain normal growth and flowering. If these trace elements are lacking in liquid fertilizer, it may lead to poor performance of the plant during flowering. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art and solve at least one technical problem raised in the background technology, for example, if the content of one or more nutrient elements in the compound liquid fertilizer is insufficient or excessive after use, it may cause the problem that crop photosynthesis is hindered.

[0007] The technical solution adopted by the present invention to solve the technical problem is: the method for promoting bright colors of flowers by using a lincomycin finished liquid fertilizer of the present invention comprises the following steps: Step 1: diluting lincomycin dry powder at a mass ratio of 1:100 to obtain a lincomycin finished liquid; Step 2: aeration culture in a liquid culture medium containing starch, yeast powder, soybean powder, yeast extract and inorganic salts, during the lincomycin fermentation process, adjusting the ammonium ion concentration in the initial fermentation medium to 57±5mmol / L, and culturing lincomycin Streptomyces under suitable conditions; when the ammonium ion concentration in the fermentation medium is 0.2-1.5mmol / L, adding ammonium ions, and then controlling the ammonium ion concentration in the fermentation medium to 2-5mmol / L until the fermentation is completed, and the fermentation time is controlled to be 36-110h, to obtain a lincomycin fermentation liquid; Step 3: Dissolve urea, potassium chloride, zinc sulfate and ferric humate solution in water and mix well to prepare a nutrient solution; After 200 mesh zeolite is subjected to a high temperature treatment at 200°C, the above nutrient solution is sprayed onto the zeolite; Drying the zeolite in the sun or by drying it to reduce its moisture content to no more than 5%; The remaining chemical fertilizer is then evenly mixed with the zeolite to form a lincomycin finished liquid fertilizer.

[0013] As a further solution of the present invention: the preparation process of the modified zeolite comprises the following steps: Dissolve chitosan in acetic acid, stir and mix to dissolve, then add dimethyldiallyl ammonium chloride solution, mix well and heat to react, cool to room temperature after the reaction, then add acetone to generate precipitation, wash, dry and grind into powder to obtain quaternized chitosan; The natural zeolite is first mixed with quaternary ammonium chitosan and water, stirred evenly, then dripped into a sodium hydroxide solution, washed and dried, then stirred and mixed evenly with lanthanum nitrate hexahydrate, adjusted the pH to 11-14, stirred, washed and dried; or the natural zeolite is first stirred and mixed evenly with lanthanum nitrate hexahydrate, adjusted the pH to 11-14, stirred, washed and dried, then mixed with quaternary ammonium chitosan and water, stirred evenly, then dripped into a sodium hydroxide solution, washed and dried, to obtain a lanthanum-chitosan-zeolite composite material; The lanthanum-chitosan-zeolite composite material is mixed with cement to form granules, dried in the shade, steam cured, and dried to obtain phosphorus-removing and antibacterial modified zeolite filler.

[0015] As a further solution of the present invention: the volume percentage of dimethyldiallylammonium chloride in the dimethyldiallylammonium chloride solution is 20-25 vol%.

[0016] As a further solution of the present invention: the mass ratio of natural zeolite to quaternized chitosan is 3:0.5-1; the mass ratio of lanthanum-chitosan-zeolite composite material to cement is 2-8:1; the washing and drying temperature is 50-60°C.

[0017] The beneficial effects of the present invention are as follows: The invention dilutes lincomycin dry powder according to a mass ratio of 1:100 to obtain a lincomycin finished liquid; aerates and cultures the lincomycin in a liquid culture medium containing starch, yeast powder, soybean powder, yeast extract and inorganic salts; during the lincomycin fermentation process, adjusts the ammonium ion concentration in the initial fermentation culture medium to 57±5mmol / L, and cultures lincomycin streptomyces under suitable conditions; when the ammonium ion concentration in the fermentation culture medium is 0.2-1.5mmol / L, adds ammonium ions, and then controls the ammonium ion concentration in the fermentation culture medium to 2-5mmol / L until the fermentation is completed, and controls the fermentation time to 36-110h to obtain a lincomycin fermentation liquid; dissolves urea, potassium chloride, zinc sulfate and fulvic acid iron solution in water and mixes them uniformly to prepare a nutrient solution; treats a zeolite with a fineness of 200 meshes at a high temperature of 200°C, and then sprays the nutrient solution on the zeolite; airs or dries the zeolite to reduce its water content to no more than 5%; and uniformly mixes the remaining chemical fertilizer with the zeolite to prepare a lincomycin finished liquid liquid fertilizer; Modified zeolite plays multiple important roles in fertilizers, which are mainly due to its unique structure and properties. The following is a detailed summary of the role of zeolite in fertilizers: Provide trace elements: Modified zeolite is rich in trace elements, such as calcium, magnesium, iron, etc., which are essential for the growth and development of plants. By adding zeolite to fertilizers, these essential trace elements can be provided to plants to help them maintain a healthy growth state.

[0018] Improve soil structure: Modified zeolite has excellent water absorption and ion exchange properties, which can improve soil permeability and structure. It absorbs and releases water, helps the soil maintain proper moisture, and prevents the soil from being too wet, which is beneficial to the growth of roots and plants.

[0019] Regulating soil pH: The ion exchange properties of modified zeolite enable it to regulate soil pH. In acidic soils, zeolite can absorb excess hydrogen ions, reducing the acidity of the soil; while in alkaline soils, zeolite releases hydrogen ions, helping to reduce the alkalinity of the soil. This regulating effect helps create a soil environment suitable for plant growth.

[0020] Promote nutrient absorption: The ion exchangeability of modified zeolite also helps plants absorb nutrients from the soil. It can adsorb and release nutrients needed by plants, improve nutrient utilization efficiency, and promote healthy growth of plants. Zeolite relies on its strong adsorption force and the electrostatic attraction of cations to tightly bind a large number of nutrient elements around the internal lattice. When mixed with chemical fertilizers, it has the functions of retaining nitrogen and reducing phosphorus fixation, which can promote the long-term maintenance of fertilizer effect.

[0021] Increase soil water retention: Modified zeolite can absorb and retain water, increasing the water retention capacity of the soil. This is especially important in arid areas or places where the soil is poorly drained, helping to provide a steady supply of water to maintain plant growth.

[0022] Inhibit harmful substances in the soil: Modified zeolite also has the ability to adsorb harmful substances, such as heavy metal ions and some chemicals. By adding zeolite, the impact of these harmful substances on plants can be reduced and the environmental friendliness of the soil can be improved.

[0023] Reduce fertilizer loss: Modified zeolite has strong adsorption capacity. After being mixed with fertilizer, zeolite crystals retain nutrients such as nitrogen and then slowly release them into the ground, improving fertilizer efficiency and extending the fertilizer supply time of the soil, reducing the rapid release of fertilizer components and the loss of fertilizer to the air and water, and reducing the pollution of fertilizer to the environment The lincomycin finished liquid fertilizer of the present invention effectively increases the flowering period, thereby promoting the bright color effect of flowers.
