TECHNICAL FIELD

[0001] The present application relates to the technical field of garden plant cultivation, in particular to a red ball flower period regulation composition and a fertilization method. BACKGROUND

[0002] In current garden plant cultivation, red ball is an important ornamental shrub, and its natural flowering period is difficult to meet the ornamental needs in different seasons, and there are problems such as sparse flowers and long internodes, so it is often planted as a general hedge plant without ornamental effect. The existing technology mainly relies on variety selection and environmental regulation (such as temperature and light management) to indirectly affect the flowering period, but the operation is complex, the cost is high, it is difficult to implement in a large range or open space, and the preparation period is long and the flexibility is poor. The natural flowering period of red ball is strictly limited by geographical environment and climate conditions, and cannot be flexibly adjusted, which limits its ornamental value at a specific time, and the existing environmental regulation means (such as greenhouse control and shading treatment) can affect the flowering period, but the cost is high and the applicability is insufficient. SUMMARY

[0003] In view of the deficiencies of the prior art, the present application provides a red ball flower period regulation composition and a fertilization method, which solves the problem that the flowering period of red ball is limited by geographical environment and climate conditions and is difficult to control.

[0004] To achieve the above object, the present application realizes the following technical scheme: a red ball flower period regulation composition, comprising the following components by weight: 100-200 parts of nitrogen, phosphorus and potassium compound fertilizer, 2-12 parts of calcium, magnesium and zinc fertilizer, 1-2 parts of borax, 1000-2000 parts of organic matter fertilizer, 0.5-1.0 parts of polyaspartic acid, 0.1-0.3 parts of polyamine substance, and 5-10 parts of compound microbial agent.

[0012] Preferably, the nitrogen, phosphorus, and potassium compound fertilizer in S1 is high-nitrogen and high-potassium type, with a N-P2O5-K2O ratio of 20-25:8-12:18-22.

[0013] Preferably, the organic fertilizer in S2 specifically includes: mixing livestock and poultry manure with straw at a weight ratio of 3:1, adding 0.5% of total mass of matured bacteria, and composting at 55-65°C for 15-20 days, with 3-4 times of turning during the period, until the water content is reduced to 30-35%.

In spring from February to March, uniformly spread the composition around the soil at the base of the red ball, shallowly till 10-15 cm, and irrigate with 20-30 L / m 2 ; B. 60 days before flowering, dig holes at the edge of the plant canopy projection, with a hole depth of 15-20 cm, cover the soil after applying the composition, and spray the flower-promoting regulator and potassium dihydrogen phosphate solution at an interval of 7-10 days, for a total of 2-3 times; C. In late autumn from October to November, dig a ring-shaped ditch along the plant root distribution area, with a ditch depth of 20-30 cm, apply matured organic matter fertilizer and complex microbial agent, and drip irrigate after covering the soil, with an irrigation amount of 30-40 L / m 2 .

[0015] The present application provides a red ball flower period regulation composition and fertilization method. The following advantages are provided: 1.

The problem of red ball flower period being difficult to control due to geographical environmental and climatic conditions is solved.

[0016] 2. In the present application, spermidine and spermine are compounded at a weight ratio of 2:1.

[0017] 3. In the present application, the synergistic effect of composting and stirring homogenization realizes the micro-combination of organic fertilizer and inorganic compound fertilizer, which increases the organic matter content of red ball rhizosphere soil by 1.5-2.0%, improves the nutrient utilization rate by 30-40%, and avoids the risk of disease and insect pests caused by raw manure. The problem of unstable flower period regulation effect caused by unrotted organic fertilizer, asynchronous nutrient release, and uneven mixing is solved.

[0018] 4. In the present application, fertilization is carried out in stages. In spring, shallowly spread and apply 20-30L / m 2 of water to promote new shoot growth and photosynthesis of red ball; 60 days before flowering, dig holes at the edge of the tree canopy and apply fertilizer, florigenic regulator, and potassium dihydrogen phosphate to improve flower bud differentiation rate and flowering uniformity; at the end of autumn, dig ring-shaped trenches along the root distribution area and apply rotten organic matter and compound microbial agents to improve the organic matter content and microbial diversity of the rhizosphere soil and enhance the cold resistance of the plant. Ultimately, the red ball flower period is precisely regulated, breaking through the limitations of geographical environment and climate, significantly improving the accuracy of flower period regulation, ornamental effect, and technical applicability. The problems of insufficient accuracy of flower period regulation and poor ornamental effect are solved. BRIEF DESCRIPTION OF DRAWINGS

The following advantages are provided: Figure 2 The present application provides a red ball flower period regulation composition and fertilization method. The following advantages are provided: DETAILED DESCRIPTION

[0020] The technical solutions of the present application will be described clearly and completely below in combination with the drawings of the specification. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the protection scope of the present application.

[0021] Please refer to the drawings of the specification Figure 1 The embodiment of the present application provides a red ball flower period regulation composition, which comprises the following components in parts by weight: nitrogen, phosphorus and potassium compound fertilizer 100-200 parts, calcium, magnesium and zinc fertilizer 2-12 parts, borax 1-2 parts, organic matter fertilizer 1000-2000 parts, polyaspartic acid 0.5-1.0 parts, polyamine substance 0.1-0.3 parts, and compound microbial agent 5-10 parts.

[0022] Specifically, by adding the nitrogen, phosphorus and potassium compound fertilizer, a composition containing high-nitrogen, high-potassium and low-phosphorus nutrients is obtained, so as to provide differentiated basic nutrients for the vegetative growth and reproductive growth of the red ball.

[0023] By adding the calcium, magnesium and zinc fertilizer, a composition containing soluble calcium, magnesium and zinc compounds is obtained, so as to supplement trace elements and enhance the stress resistance of the plant.

[0024] By adding the borax, a composition containing borate is obtained, so as to promote the flower bud differentiation, pollen tube elongation and fertilization process of the red ball.

[0025] By adding the organic matter fertilizer, a composition containing humus and balanced basic nutrients is obtained, so as to improve the soil aggregate structure and release the organic nutrients.

[0026] By adding the polyaspartic acid, a composition containing organic chelating agent is obtained, so as to chelate metal ions such as iron, manganese and zinc in the soil and improve the root absorption effectiveness of the red ball.

[0027] By adding the polyamine substance, a composition containing plant growth regulating factor is obtained, so as to regulate the balance between auxin and cytokinin in the red ball, promote the morphological differentiation of flower buds, and the like.

[0028] By adding the compound microbial agent, a composition containing functional microbial flora is obtained, so as to decompose soil insoluble phosphorus and potassium salts, fix nitrogen in the air, and improve the effective nutrient content in the rhizosphere.

[0029] Through the synergistic effect of each component, the precise regulation of the flowering period of red ball is achieved, breaking the limitations of geographical environment and climate conditions; the high-nitrogen high-potassium low-phosphorus compound fertilizer matched with trace elements, organic matter, etc. supplies nutrients differentially for red ball at different growth stages, enhances the plant resistance, promotes flower bud differentiation, pollen tube development and fertilization process, improves photosynthetic efficiency and flower quality; the chelation of polyaspartic acid, the regulation of polyamine substances on plant hormones and the improvement of soil microecology by compound microbial agent improve the nutrient absorption efficiency and soil fertility, improve the soil structure, prolong the ornamental period, and reduce the fertilization frequency and cost, improve the applicability and ornamental value of the technology. The problem of red ball flower period being difficult to control due to the limitation of geographical environment and climate conditions is solved.

[0030] The ratio of N-P2O5-K2O in the nitrogen, phosphorus and potassium compound fertilizer is 20-25:8-12:18-22.

[0031] Specifically, the high-nitrogen ratio (20-25) utilizes the principle of amino acid synthesis path to promote chlorophyll synthesis in leaf blades during the spring vegetative growth period of red ball (such as glutamic acid and alpha-ketoglutaric acid generating glutamine under the catalysis of glutamine synthetase to provide nitrogen source for chlorophyll porphyrin ring), accelerates the carbon assimilation process of photosynthesis, and at the same time stimulates the synthesis of cell division substances (such as zeatin) precursors to stimulate cell division of stem tip meristem, achieving an effect of increasing new shoot daily growth by 20%-30%.

[0032] The low-phosphorus ratio (8-12) is based on the energy metabolism regulation principle of phosphorus in the reproductive growth stage, and provides energy carriers for flower organ primordium differentiation during the flower bud differentiation period by participating in ATP (adenosine triphosphate) synthesis (such as 3-phosphoglyceraldehyde dehydrogenation to generate 1,3-diphosphoglycerate in the glycolysis pathway to release energy for ATP synthesis), as a component of nucleic acids (DNA / RNA), ensuring the transcription and expression of flower bud differentiation related genes (such as LFY gene), solving the problem of excessive vegetative growth inhibiting flowering caused by traditional high-phosphorus formula.

[0033] The high-potassium ratio (18-22) utilizes the potassium ion osmotic regulation principle to activate the potassium ion channel (such as inward rectifying K + channel KAT1) in guard cells during the flowering period, regulates the opening and closing of stomata to reduce water transpiration, and at the same time promotes the transportation of sugar substances (such as sucrose) to flowers (through the proton-coupled transport mechanism involved in K + loading process in phloem), so that the osmotic pressure of petal cell sap is maintained at 0.8-1.2 MPa, ensuring the fullness and color stability of flowers, and prolonging the flowering period by 15-20 days compared with the traditional formula.

[0034] By designing N-P2O5-K2O in the compound fertilizer according to the ratio of 20-25:8-12:18-22, high nitrogen is used to promote new shoot germination and leaf growth during the vegetative growth period of red ball, so that the daily growth of new shoots is increased by 20%-30%; during the flower bud differentiation period, low phosphorus is used to regulate energy metabolism and gene expression to ensure the differentiation of flower organ primordia; during the flowering period, high potassium is used to maintain cell osmotic pressure, reduce water transpiration, and promote sugar transport, so that the petal cell osmotic pressure is maintained at 0.8-1.2 MPa, the flowering period is prolonged by 15-20 days compared with the traditional formula, and the accurate supply of nutrients in different stages is realized. The problem that the ratio of nitrogen, phosphorus and potassium in the compound fertilizer is fixed in the prior art and cannot adapt to the dynamic changes of nutrient requirements for red ball flowering regulation is solved.

[0035] The calcium, magnesium and zinc fertilizer is composed of calcium acetate, magnesium sulfate and zinc sulfate according to the weight ratio of 40-50:30-40:20-30.

[0036] Specifically, the chelation stability principle of acetate ions (CH3COO-) and calcium ions (Ca 2+ ) is used. The Ca 2+ is transported to the root elongation zone through the plasmodesmatal pathway and participates in the synthesis of pectic acid calcium in the cell wall (such as the cross-linking of galacturonic acid and Ca 2+ to form a pectin network), thereby enhancing the rigidity of the cell structure and increasing the lodging resistance of red ball branches by 40%-50%. Meanwhile, Ca 2+ activates the activity of pollen tube elongation-related enzymes (such as calcium-dependent protein kinase CDPK) as a second messenger, ensuring the normal development of pollen tubes during the flower bud differentiation period.

[0037] Based on the structural characteristics of magnesium ions (Mg 2+ ) as the center atom of the chlorophyll porphyrin ring, Mg 2+ combines with protoporphyrin IX in leaf chloroplasts to form chlorophyll a / b, so that the absorption peak of the photosystem II (PSII) reaction center is maintained at 680 nm (red light region), and the photosynthetic rate is increased by 25%-30%. Meanwhile, Mg 2+ acts as an activator of ATPase (such as participating in the catalysis of glucose phosphorylation by hexokinase) to promote carbohydrate metabolism and provide sufficient carbon source for flower bud differentiation.

[0038] Zinc ions (Zn 2+ ) activate the key enzyme (tryptophan transaminase) for auxin synthesis to promote the conversion of tryptophan to indole acetic acid (IAA) in the apical meristem of new shoots, so that the IAA concentration is maintained at 15-20 μg / g FW, which stimulates the germination of lateral buds and shortens the internodes, solving the problem of excessively long internodes caused by traditional zinc fertilizer application. Meanwhile, Zn 2+ participates in the synthesis of cytokinin oxidase to regulate the degradation rate of cytokinin, avoiding excessive vegetative growth and inhibiting flower bud differentiation.

[0039] By compounding calcium acetate, magnesium sulfate, and zinc sulfate in a weight ratio of 40-50:30-40:20-30, the calcium in calcium acetate enhances the rigidity of the cell wall to improve the lodging resistance of the branches by 40%-50%, the magnesium in magnesium sulfate is involved in the synthesis of chlorophyll to increase the photosynthetic rate by 25%-30%, and the zinc in zinc sulfate regulates the synthesis of auxin to shorten the internode length, thereby realizing the multi-dimensional optimization of the structural stability, photosynthetic efficiency, and hormone balance of the red ball during the flowering period, and ensuring the differentiation of flower buds and the quality of flowering. The problem of element antagonism and low absorption efficiency caused by the application of single calcium-magnesium-zinc fertilizer in the prior art is solved.

[0040] The polyamine substances are spermidine and spermine, and the weight ratio of the two is 2:1.

[0041] Specifically, spermidine, as the main component of the polyamine substances, binds to histone H1 to change the chromatin structure and activate the transcription of flower meristem determination genes (such as AP1 gene). During the flowering induction period of the red ball, when the concentration of spermidine reaches 5-8 μmol / g FW, the FT protein synthesized by the leaves is transported to the stem apex, causing the stem apex meristem to switch from vegetative growth to reproductive growth, and shortening the time required for flower bud differentiation by 10-15 days.

[0042] Spermine maintains the IAA concentration in the new shoots of the red ball at 10-15 ng / g FW by inhibiting the activity of IAA oxidase, thereby avoiding the inhibitory effect of high-concentration auxin on flower bud differentiation. Meanwhile, spermine promotes the synthesis of CTK, causing the CTK / IAA ratio to be maintained at 0.3-0.5, which is conducive to the formation and development of flower primordia.

[0043] When spermidine and spermine are compounded in a weight ratio of 2:1, they can enhance the stability of the cell membrane through synergistic action. Specifically, they are embedded in the phospholipid bilayer of the cell membrane to increase the membrane lipid phase transition temperature, so that the red ball can still maintain normal pollen mother cell meiosis under conditions of temperature fluctuations (such as a diurnal temperature difference of more than 10℃), and the pollen viability is increased by 30%-40% compared to single polyamine treatment.

[0044] By compounding spermidine and spermine in a weight ratio of 2:1, the use of spermidine to activate the transcription of flower meristem determination genes and promote the transportation of FT protein, and the use of spermine to inhibit the oxidation of IAA and maintain hormone balance, together with the synergistic enhancement of cell membrane stability, the time required for flower bud differentiation of the red ball is shortened by 10-15 days, the pollen viability is increased by 30%-40%, and the red ball can still maintain normal flowering under conditions of a diurnal temperature difference of more than 10℃, thereby realizing the precise regulation of the flowering period under different climate conditions. The problems of low flowering induction efficiency and sensitivity to environmental temperature during the flowering period caused by the application of single polyamine in the prior art are solved.

[0045] The compound microbial agent is composed of phosphate-solubilizing bacteria, potassium-solubilizing bacteria, and nitrogen-fixing bacteria in a weight ratio of 1:1:1.

[0046] Specifically, phosphate-solubilizing bacteria (such as Bacillus megaterium) convert insoluble calcium phosphate (Ca3(PO4)2) and iron phosphate (FePO4) in the soil into soluble phosphate ions (PO4) by secreting acid phosphatase (EC3.1.3.2) and organic acids such as citric acid and gluconic acid. 3- In the root microenvironment of *Pyrrosia lingua*, phosphate-solubilizing bacteria produce H+. + It lowers the local pH by 1.5-2.0 units, causing the dissociation of phosphorus complexes such as Ca-P and Fe-P, releasing PO4. 3- Through the root system H + - The ATPase-driven cotransport system is absorbed, increasing the available phosphorus content in the soil by 40%-60%, meeting the phosphorus requirements during the flower bud differentiation period.

[0047] Potassium-solubilizing bacteria (such as Bacillus mucilaginosus) disrupt the crystal structure of minerals like feldspar and mica by synthesizing extracellular polysaccharides and thermophilic proteases. The extracellular polysaccharides react with potassium ions (K+). + The formation of water-soluble complexes and the degradation of the aluminosilicate layer on the mineral surface by thermophilic proteases allow the K+ within the crystal lattice to form water-soluble complexes. + It is released into the soil solution. At the roots of *Polygonum cuspidatum*, the biofilm structure formed by potassium-solubilizing bacteria can adsorb the released potassium. + Through the root system K + The pathway (such as AKT1) transports potassium ions into the plant, maintaining the potassium ion concentration in the leaves at 1.5-2.0% (dry weight), thus enhancing the flowers' resistance to adverse conditions.

[0048] Nitrogen-fixing bacteria (such as rhizobia) catalyze the reduction of nitrogen (N2) to ammonia (NH3) via a nitrogenase complex (composed of ferritin and molybdenum-ferritin). In an anaerobic microenvironment, nitrogenase consumes ATP (16 mol of ATP is consumed for every 1 mol of N2 fixed) and reducing power (NADPH) to convert N2 to NH4. + Then, glutamate is synthesized through glutamate dehydrogenase (GDH), providing an organic nitrogen source for the red velvet ball. This process increases the nitrogen content of the rhizosphere soil by 20-30% and reduces the number of nitrogen fertilizer applications by more than 50%.

[0049] The phosphorus solubilizing bacteria, potassium solubilizing bacteria and nitrogen fixing bacteria are compounded according to a weight ratio of 1:1:1, the organic acid secreted by the phosphorus solubilizing bacteria is used to activate the soil insoluble phosphorus, the potassium solubilizing bacteria is used to destroy the mineral crystal lattice to release potassium ions, and the nitrogen fixing bacteria is used to convert nitrogen into ammonia through the synergistic metabolism, so that the effective phosphorus content in the soil around the red ball is increased by 40%-60%, the potassium content is increased by 30%-50%, and the nitrogen content is increased by 20-30%, the nitrogen fertilizer application frequency is reduced by more than 50%, the soil nutrient supply during the flower period is realized, the fertilizer application cost is reduced by 30%-40%, and the plant stress resistance is enhanced.

[0050] The humic acid content of the organic matter fertilizer is greater than or equal to 30%, and the total content of nitrogen, phosphorus and potassium is greater than or equal to 5%.

[0051] Specifically, the humic acid forms a stable organic-inorganic complex with calcium and magnesium ions in the soil through functional groups such as phenolic hydroxyl and carboxyl, and the dispersed clay particles in the soil are cemented into a granular structure with a diameter of 0.25-5 mm, so that the soil porosity is increased by 15-20% and the field water capacity is increased by 25-30%. In the red ball root distribution area, the colloidal network formed by the humic acid can adsorb heavy metal ions (such as Cd 2+ , Pb 2+ ), reduce their bioavailability, and at the same time, through ion exchange (exchange capacity 150-300 mmol / kg), adsorb and store nutrients such as ammonium nitrogen and potassium ions, and reduce leaching loss.

[0052] The organic matter fertilizer with a total content of nitrogen, phosphorus and potassium greater than or equal to 5% releases nutrients continuously in the growth cycle of the red ball through microbial decomposition. Among them, the ammonium nitrogen (NH4 + ) is absorbed by the root NH4 + transport protein (AMT) and participates in chlorophyll synthesis; the water-soluble phosphorus (H2PO4 - ) is activated by the root acid phosphatase for ATP synthesis; and the exchangeable potassium (K + ) regulates the opening and closing of stomata through the guard cell K + channel to maintain the flower turgor pressure. The release process is synchronized with the fertilizer requirement of the red ball, and the nitrogen release accounts for 40-50% in the spring vegetative growth period, and the phosphorus and potassium release accounts for 60-70% in the autumn flower bud differentiation period.

[0053] The complex system of humic acid and nitrogen, phosphorus and potassium releases nutrients continuously in the growth cycle of the red ball through the dual mechanisms of "structure improvement-nutrient slow release". In the soil environment with a pH of 6.0-7.5, the buffering effect of humic acid makes the soil acid-base fluctuation amplitude ≤0.5 units, creates suitable conditions for microbial activities (such as nitrogen fixing bacteria and phosphorus solubilizing bacteria), and further promotes the biological conversion efficiency of nitrogen, phosphorus and potassium to be increased by 30-40%.

[0054] The design of the organic matter fertilizer with humic acid content ≥30%, total nitrogen, phosphorus and potassium content ≥5% indexes, the phenolic hydroxyl and carboxyl of humic acid form organic-inorganic complex with soil ions, so that the soil porosity is increased by 15-20%, the field water capacity is increased by 25-30%, and the nutrient leaching loss is reduced through ion exchange; the total nitrogen, phosphorus and potassium content ≥5% ensures that 40-50% of the nitrogen is released during the spring vegetative growth period of red ball, and 60-70% of the phosphorus and potassium are released during the autumn flower bud differentiation period, which is synchronized with the plant nutrient demand law, and the buffer effect of humic acid makes the soil acid-base fluctuation amplitude ≤0.5 units, promotes the conversion efficiency of microorganisms to nutrients by 30-40%, and realizes the synergy of soil structure improvement and precise nutrient supply. The problems of poor soil aggregate structure improvement effect and weak nutrient adsorption capacity caused by insufficient humic acid content in the prior art are solved.

[0055] Please refer to the attached Figure 1 A preparation method of a red ball flowering period regulating composition, for a red ball flowering period regulating composition, comprising the following steps: S1, nitrogen, phosphorus and potassium compound fertilizer, calcium, magnesium and zinc fertilizer, borax are put into a double-shaft mixer, and mixed at a speed of 20-30 revolutions per minute for 15-20 minutes.

[0056] The nitrogen, phosphorus and potassium compound fertilizer in S1 is high-nitrogen and high-potassium type, and the N-P2O5-K2O ratio is 20-25:8-12:18-22.

[0057] Specifically, the opposite rotating paddles of the double-shaft mixer form a shear force field, so that the solid particles with a particle size of 5-500 μm produce radial and axial movement, and through the triple action of "convection mixing-diffusion mixing-shear mixing", the crystal particles (such as potassium nitrate and urea crystals) of high-nitrogen and high-potassium compound fertilizer and the surfaces of trace element salts such as calcium acetate and magnesium sulfate are fully exposed. When the speed is controlled at 20-30 revolutions per minute, the filling rate of the material is maintained at 30%-50%, and the collision frequency between particles reaches 10-20 times per second, ensuring that the variation coefficient of the uniformity of each component is ≤5%.

[0058] The potassium ion (K + ) in the high-nitrogen and high-potassium compound fertilizer and the magnesium ion (Mg 2+ ) in the calcium, magnesium and zinc fertilizer form an ion pair during stirring, reducing the competitive adsorption of calcium and magnesium ions in the soil through charge interaction. For example, K + dissociated from potassium nitrate and Mg 2+ dissociated from magnesium sulfate form K + -Mg 2+The composite ions make the diffusion coefficients of both in the soil solution increase by 15%-20%, and the low phosphorus content (P2O5 accounts for 8-12%) avoids the formation of insoluble precipitates (such as calcium phosphate and zinc phosphate) of phosphate and calcium and zinc, ensures the uniform dispersion of borax (H3BO3) in a molecular state, and reduces the inhibition of boron absorption caused by local high phosphorus.

[0059] The mixing time of 15-20 minutes makes the material experience three stages of "initial particle rearrangement-mid-term interface reaction-late-term balance stability". In the initial stage (0-5 minutes), the large particle compound fertilizer is broken to 100-200 μm; in the mid-term stage (5-15 minutes), humic acid (from the subsequently added organic matter fertilizer) forms a chelate with metal ions (stability constant lgK=3.5-5.0); in the late stage (15-20 minutes), borax is adsorbed on the surface of the compound fertilizer particles through hydrogen bonding, forming a coating layer with a thickness of 50-100 nm, so that the boron element is released in the soil in a gradient, continuously meeting the demand of red ballflower for boron during the bud differentiation period (0.5-1.0 mg / kg of soil).

[0060] Through the control of stirring speed and time, the micro-uniform dispersion of high-nitrogen and high-potassium compound fertilizer and medium and trace element fertilizer is realized, so that the nitrogen absorption rate of red ballflower during the vegetative growth period is increased by 25%-30%, the potassium utilization rate during the reproductive growth period is increased by 35%-40%, and the burning root phenomenon caused by too high local nutrient concentration is avoided. The problem of asynchronous release of nutrients and serious antagonism between elements caused by uneven mixing of the prior art is solved.

[0061] S2, add organic matter fertilizer, continue stirring for 25-35 minutes.

[0062] The organic fertilizer in S2 specifically includes: mixing livestock and poultry manure and straw at a weight ratio of 3:1, adding 0.5% of total mass of mature bacteria agent, and composting at 55-65℃ for 15-20 days, during which the pile is turned over 3-4 times until the water content is reduced to 30-35%.

[0063] Specifically, livestock manure provides nitrogen-containing organic matter (protein accounts for 20-30%) and microbial community (such as Bacillus accounts for 40-50%), straw supplements cellulose (accounts for 40-50% of dry weight) and carbon source, and the two are mixed at a ratio of 3:1 to form an ideal fermentation substrate with a C / N ratio of 20-25:1. 0.5% of the matured bacterial agent (containing cellulose-decomposing bacteria and actinomycetes) starts the high-temperature fermentation stage at 55-65°C, in which the cellulose-decomposing bacteria secrete β-glucosidase (enzyme activity ≥50 U / mL) to decompose straw cellulose into glucose, and proteins generate amino acids under the action of protease to provide precursor materials for humus synthesis. Turning over 3-4 times maintains the oxygen content of the material at 8-12%, promotes the metabolism of aerobic microorganisms, and raises the temperature of the pile to above 55°C within 3-5 days and maintains it for 7-10 days, killing pathogenic bacteria (such as Escherichia coli with a killing rate ≥90%) and insect eggs, and accelerating the demethylation reaction of lignin to form humic acid precursors with a molecular weight of 1000-5000 Da.

[0064] During the 25-35 minute stirring process, the shear force of the paddle of the double-shaft stirrer further breaks the organic matter particles (particle size 1-5 mm) after maturation to 500-1000 μm, forming a micro-structure with the inorganic fertilizer mixed in the previous step. At this time, the water content of the organic matter fertilizer is 30-35%, making the humic acid (content ≥30%) in sol state, which is adsorbed on the surface of the compound fertilizer particles through hydrogen bonds and ionic bonds, forming an organic-inorganic coating with a thickness of 200-500 nm, in which the carboxyl group (-COOH) of the humic acid forms a stable chelate (stability constant lgK = 3.2-4.5) with the potassium ion (K + ) in the compound fertilizer, reducing the leaching loss of potassium in the soil (loss rate reduced by 25-30%).

[0065] The humus (accounts for 40-50% of dry weight) formed during the composting process has a porous structure (specific surface area 100-200 m 2 / g), and after fully contacting with inorganic nutrients in the stirring stage, an "organic colloid-inorganic ion" complex is formed. When this composition is applied to the soil, the weakly acidic (pH 5.5-6.5) environment of the humic acid makes the wrapped nitrogen, phosphorus and potassium release slowly: 30-40% of the ammonium nitrogen (NH4 + ) is released within 7-10 days to meet the growth needs of the new shoots of red ball in spring; water-soluble phosphorus (H2PO4 - ) is continuously released within 20-30 days, synchronizing with the high phosphorus demand during the flower bud differentiation period; and the exchangeable potassium (K + ) is gradually released through ion exchange, keeping the potassium content of the leaves at 1.5-2.0% (dry weight) during the flowering period.

[0066] Through the synergy of composting and stirring homogenization, the micro-composite of organic fertilizer and inorganic compound fertilizer is realized, the organic matter content of the soil around the red ball is increased by 1.5-2.0%, the nutrient utilization rate is increased by 30-40%, and the risk of pests and diseases caused by the application of raw manure is avoided. The problem of unstable flower period regulation effect caused by unrotted organic fertilizer, asynchronous nutrient release and uneven mixing in the prior art is solved.

[0067] S3, spray polyaspartic acid solution and polyamine substances, keep the rotation speed at 30-40 revolutions per minute, mix for 10-15 minutes.

[0068] Specifically, the linear molecular chain of polyaspartic acid (molecular weight 10000-20000 Da) is distributed with a large number of carboxyl groups (-COOH) and amide groups (-CONH-), which are dissociated into COO - and Mg, Zn and other metal ions form five-membered or six-membered ring chelates (stability constant lgK=4.5-6.0). When the rotation speed is controlled at 30-40 revolutions per minute, the shearing force of the material makes the polyaspartic acid molecules fully unfold, and the contact probability of their chelating sites with the surface of the trace element salts of calcium acetate, magnesium sulfate and other trace element salts mixed in the previous stage is increased by 30-40%, forming soluble chelates (such as polyaspartic acid-Ca 2+ ), which increases the availability of trace elements in the soil by 50-60% and avoids the deficiency caused by the precipitation of metal ions.

[0069] The polyamine substance composed of spermidine and spermine in a weight ratio of 2:1 is adsorbed on the surface of the polyaspartic acid-metal ion chelate through hydrogen bonds and van der Waals forces during stirring, forming a composite coating with a thickness of 50-100 nm. Among them, the amino group (-NH2) of spermidine reacts with the carboxyl group of polyaspartic acid to form a stable ionic bond (dissociation constant pKa=9.0-10.5), so that the adsorption amount of polyamine substances on the surface of the composite is 80-90%. The adsorption structure is gradually desorbed under the action of organic acids (such as citric acid) secreted by the red ball root system, slowly releasing polyamine substances, maintaining the rhizosphere concentration at 5-10 μmol / L, and continuously activating the expression of flower meristem determinate genes (such as AP1 gene).

[0070] 10-15 minutes of mixing duration allows the system to experience three stages of "molecular diffusion - interface reaction - stable adsorption". Within the initial 5 minutes, the polyaspartic acid solution is uniformly dispersed into the material gap (water content increases to 35-40%), forming a continuous phase; at 5-10 minutes, the polyamines react with polyaspartic acid to form a network polymer; at 10-15 minutes, the polymer wraps around the inorganic fertilizer particle surface to form a "polyaspartic acid-polyamine-inorganic nutrient" ternary complex, with a particle size distribution concentrated in 200-500 μm, a specific surface area of 50-80 m 2 / g, ensuring that the nutrient release rate after application to the soil is synchronized with the red ball period of flower bud differentiation - polyaspartic acid chelated trace elements are slowly released within 10-15 days, and polyamines act continuously within 20-30 days to promote flower bud differentiation.

[0071] Through precise control of speed and time, the synergistic effect of trace element chelation and flower period hormone regulation is achieved, which increases the absorption rate of red ball to calcium, magnesium and zinc by 40-50%, shortens the flower bud differentiation time by 10-15 days, and avoids the growth inhibition phenomenon caused by high local concentration of polyamines. The problem of uneven mixing of polyaspartic acid and polyamines in the prior art and easy molecular degradation is solved.

[0072] S4, add a compound microbial agent and stir for 5-8 minutes at a temperature ≤30°C.

[0073] Specifically, the functional bacteria (such as Bacillus megaterium, Bacillus mucilaginosus) in the compound microbial agent (phosphorus solubilizing bacteria, potassium solubilizing bacteria, nitrogen-fixing bacteria in a weight ratio of 1:1:1) maintain the best conformation of the enzyme system (such as acid phosphatase, exopolysaccharide synthase) at a temperature ≤30°C, and the cell activity is maintained above 90%. When the stirring speed is controlled at 20-30 revolutions per minute, the material shear force is ≤50 Pa, which avoids the mechanical damage of the bacterial population to the cell wall. Under this condition, the microbial agent and the organic-inorganic nutrient complex formed in the early stage form micro-aggregates with a diameter of 100-200 μm, the bacterial population colonizes in the organic matter pores (pore diameter 5-10 μm), and forms a biofilm by secreting exopolysaccharides (content 10-20 mg / g dry weight), which isolates the external environment, and the survival rate of the bacterial population in the soil is increased by 40-50%.

[0074] The stirring time of 5-8 minutes enables the bacterial flora to quickly contact the nutrient substrate, and the acid phosphatase (enzyme activity ≥ 40 U / mL) secreted by the phosphorus solubilizing bacteria starts to decompose calcium phosphate in the soil at the initial stage of contact, and the thermophilic protease (optimum temperature 25-30°C) produced by the potassium solubilizing bacteria starts the mineral lattice destruction process, and the nitrogen-fixing enzyme complex (composed of ferredoxin and molybdenum-ferredoxin) of the nitrogen-fixing bacteria starts to catalyze the reduction of nitrogen gas in a low-oxygen environment (stirring causes dissolved oxygen ≤ 2 mg / L). During this process, indole acetic acid (IAA, concentration 5-10 μg / g) and cytokinin (CTK, concentration 1-2 μg / g) produced by the bacterial flora metabolism are adsorbed on the surface of the poly-aspartic acid-polyamine complex to form a “microbial-plant hormone” slow-release system, which continuously promotes the development of the red ball rhizosphere after being applied to the soil.

[0075] The low-temperature environment of ≤ 30°C inhibits the reproduction of miscellaneous bacteria (such as Escherichia coli, molds) (miscellaneous bacteria reproduction rate reduced by 60-70%), while the functional bacterial flora such as phosphorus solubilizing bacteria and potassium solubilizing bacteria establish niche advantage by preferentially utilizing carbon sources (such as glucose, amino acids) in organic matter. The micro-aggregates formed by stirring provide exclusive colonization sites for the functional bacterial flora, and the anaerobic micro-environment (oxidation-reduction potential -100 to -50 mV) inside further promotes the activity of nitrogen-fixing bacteria, making the rhizosphere nitrogen fixation efficiency increase by 30-40%, while reducing resource competition with other microorganisms.

[0076] Through precise control of temperature and time, efficient colonization and metabolic activation of the functional bacterial flora are achieved, which makes the effective phosphorus and potassium contents in the rhizosphere soil of the red ball increase by 40-60% and 30-50% respectively, and the nitrogen supply increase by 20-30%, while avoiding the problem of unstable flowering period regulation effect caused by insufficient activity of the bacterial flora. The problems of bacterial flora inactivation caused by high-temperature stirring and long-time stirring-induced miscellaneous bacterial contamination in the prior art are solved.

[0077] S5, using a granulator, the rotation speed is 15-25 revolutions per minute, and drying is performed at 60-70°C until the water content is ≤ 8%.

[0078] Specifically, the rotation speed of 15-25 revolutions per minute causes the mixed materials to form a falling state in the granulator, and the friction force (friction coefficient 0.3-0.5) and cohesive force (colloid effect from poly-aspartic acid) between the material particles reach a balance, promoting the formation of spherical particles with a particle size of 2-5 mm for the “inorganic nutrient-organic matter-microorganism” complex. At this time, the humic acid (content ≥ 30%) on the surface of the particles forms a thin film coating layer (thickness 10-20 μm) with poly-aspartic acid, which wraps the internal microbial flora (phosphorus solubilizing bacteria, potassium solubilizing bacteria, etc.) in the pore structure (pore rate 15-20%), avoiding external mechanical damage.

[0079] The drying temperature of 60-70℃ makes the internal moisture of the material (initial moisture content 35-40%) lose through the dual action of surface evaporation and internal diffusion. In the initial stage of drying (0-1h), the surface free water evaporates quickly, and the moisture content decreases to 20-25%; in the middle and late stages (1-3h), the bound water slowly escapes from the pores of organic matter (pore size 2-5nm), finally making the moisture content ≤8%. This temperature range not only ensures that the chelate structure of polyaspartic acid is not destroyed (decomposition temperature >200℃), but also maintains the dormant state of the microbial inoculant (spore survival rate ≥80%), which is activated after being applied to the soil.

[0080] The moisture content of ≤8% forms a glassy structure inside the granules, reducing the migration rate of nutrient molecules and preventing the nitrogen, phosphorus and potassium compound fertilizer from absorbing moisture and caking (critical relative humidity increases from 65% to 85%). At the same time, low moisture content inhibits the metabolic activity of microorganisms, preventing excessive reproduction of the microbial population during storage and resulting in nutrient consumption (nutrient loss rate <5%). During the granulation process, the collision frequency between material particles (5-10 times / minute) promotes the uniform distribution of trace element chelates (such as polyaspartic acid-Zn 2+ ) inside the granules, ensuring consistent nutrient release rate after application to the soil - 30-40% of nitrogen is released within 7-10 days, and potassium is continuously released within 20-30 days, synchronizing with the nutrient demand rhythm of red ball flower period regulation.

[0081] Through precise control of rotation speed, temperature and moisture content, the physical properties of the composition are stabilized and the function is long-acting, extending the red ball rhizosphere nutrient release period to 60-90 days, and the granule compression strength to 3-5N / granule, suitable for mechanized application, while avoiding mold growth due to high moisture content during storage. The problems of uneven particle size, nutrient loss during drying and microbial inactivation in the prior art are solved.

[0082] Please refer to the accompanying Figure 2 , a fertilization method for a red ball flower period regulation composition, for a red ball flower period regulation composition, comprising the following steps: A. In spring, from February to March, evenly spread the composition around the red ball rhizosphere, shallow tillage 10-15cm, and irrigation amount 20-30L / m 2 ; B. 60 days before flowering, dig holes at the edge of the plant canopy projection, hole depth 15-20cm, apply the composition, then cover the soil, spray the flower promoting regulator and potassium dihydrogen phosphate solution every 7-10 days, a total of 2-3 times; C. In late autumn, from October to November, dig a ring-shaped ditch along the plant root distribution area, ditch depth 20-30cm, apply decomposed organic matter fertilizer and complex microbial inoculant, then drip irrigation, irrigation amount 30-40L / m 2 .

[0083] Specifically, the spring 2-3 months are in the red ball of the vegetative growth period, at this time the root physiological activity is vigorous (root tip meristem cell division rate of 20-30 per hour), shallow 10-15 cm can destroy the soil hardening layer (bulk density from 1.4 g / cm 3 down to 1.2 g / cm 3 ), so that the high nitrogen and high potassium compound fertilizer (N-P2O5-K2O = 20-25:8-12:18-22) in the composition is quickly dissolved in 20-30 L / m 2 irrigation water, so that ions (NH4 + , K + ) are absorbed through the channel protein (such as AMT1, AKT1) of the root epidermis cells. Nitrogen promotes the cell division of the top meristem (cell cycle shortens by 15-20%), and potassium enhances the cell osmotic pressure regulation ability (cell sap concentration increases by 10-15%), laying a foundation for nutrient accumulation during flowering.

[0084] 60 days before flowering into the critical period of flower bud differentiation, digging holes (50-80 cm away from the trunk) at the projection edge of the crown can accurately locate the distribution area of the absorbing roots (0.2-1 mm in diameter of the root hair accounts for 60-70%). The soil temperature (20-25℃) and humidity (water content 20-25%) at the depth of 15-20 cm are most suitable for the absorption of borax (H3BO3) and calcium magnesium zinc fertilizer. Boron elements are transported through the phloem (transport rate 0.5-1.0 cm / h) to promote pollen mother cell meiosis, and calcium and magnesium ions (Ca 2+ , Mg 2+ ) participate in the synthesis of cell wall pectic acid calcium and the construction of chlorophyll porphyrin ring. Spray the flowering regulator (such as 6-BA 50-100 mg / L) and potassium dihydrogen phosphate (0.2-0.3% solution) every 7-10 days, which is quickly absorbed through the leaf stomata (opening degree 10-15 μm), adjusts the ABA / IAA ratio to 0.8-1.0, and activates the expression of flower primordium differentiation related genes (such as LFY gene).

[0085] The root system enters the growth peak period (root activity index TTC reduction amount 0.4-0.6 mg / g·h) in the late autumn 10-11 months, and the ring-shaped ditch (ditch width 20-30 cm) along the root distribution area can expose the absorbing roots and stimulate the new root germination (new root generation rate increased by 30-40%). After the mixed application of the decomposed organic matter fertilizer (humic acid content ≥30%) and the compound microbial agent (phosphorus solubilizing bacteria: potassium solubilizing bacteria: nitrogen-fixing bacteria = 1:1:1), the humic acid adsorbs the soil insoluble phosphorus and potassium (Ca-P, K-Al silicate) through ion exchange (exchange capacity 150-300 mmol / kg), and the microbial secreted acid phosphatase (enzyme activity ≥50 U / mL) and extracellular polysaccharide (concentration 10-20 mg / L) further activate the nutrients, so that the rhizosphere available phosphorus and potassium contents are increased by 40-60% and 30-50%, respectively. The drip irrigation water supply is 30-40 L / m 2 The wet area (water content 25-30%) is formed, the organic matter decomposition is promoted (decomposition rate 0.5-1.0 g / kg·d), and the microbial colonization (bacteria number up to 10 8 -10 9 CFU / g of soil) is promoted, so that the long-acting nutrients are accumulated for the next year's flowering period.

[0086] Through the phased fertilization, the shallow turning and scattering are applied in the spring 2-3 months, and the 20-30 L / m 2 water irrigation is applied, so as to promote the new shoot growth and photosynthesis of the red ball; the hole fertilization is applied at the edge of the tree crown projection 60 days before flowering, and the flower promoting regulator and potassium dihydrogen phosphate are sprayed, so as to improve the flower bud differentiation rate and flowering uniformity; the decomposed organic matter and the compound microbial agent are applied in the ring-shaped ditch along the root distribution area in the late autumn, so as to increase the rhizosphere soil organic matter content and microbial diversity and enhance the plant cold resistance, so that the red ball flowering period is finally accurately controlled, the geographical environment and climate condition limitations are broken through, and the accuracy, ornamental effect and technical applicability of the flowering period control are significantly improved.
