Background
The poplar and willow seeds are wrapped by the poplar flying catkins, the poplar flying catkins are low in density and easy to fly with wind, the poplar flying catkins accumulated on the ground can pollute the environment and even cause fire in severe cases, and if the poplar flying catkins are contacted with people with sensitive skin, skin allergy and even inflammation are easy to cause.
Patent application No. 201811460192.9 discloses a method for inhibiting the generation of flying flocs or flying hairs in tree species, in which a plant growth regulator is injected into poplar and willow to inhibit the generation of flying flocs in the poplar and the willow, but the growth regulator in the patent has poor drug effect and cannot well inhibit the generation of flying flocs in the poplar and the willow.

There is a need for a plant growth regulator that can effectively inhibit the formation of poplar willow flying floc and can be stored stably.
Disclosure of Invention
In order to solve the technical problems, the invention provides a plant growth regulator in a first aspect, which comprises the following raw materials, by mass, 5-20% of gibberellin powder, 0.5-5% of penetrating agent, 0.001-0.1% of defoaming agent, 2-9% of antifreezing agent, 8-25% of cosolvent and the balance of water, wherein the gibberellin powder comprises gibberellin and an auxiliary agent, and the auxiliary agent comprises at least one of nitrogen fertilizer, phosphate fertilizer and potassium fertilizer.
As a preferable mode, the gibberellin is at least one selected from the group consisting of gibberellin GA1, gibberellin GA3, gibberellin GA4, and gibberellin GA 7.
As a preferred technical scheme, the gibberellin is gibberellin GA3.
Gibberellin is a plant growth regulatory hormone, and the inventors found that gibberellin can promote growth, germination and development of fruiting when applied to crops such as tomatoes, potatoes, rice and wheat, but can promote growth of poplar and willow when applied to poplar and willow, but can inhibit growth of flower buds of poplar and willow to differentiate the flower buds into leaf buds, and has an effect of thinning flowers and fruits when applied to poplar and willow, so that the differentiated flower buds fall off to inhibit formation of flying-flocks of poplar and willow. Especially, gibberellin GA3 is more effective in inhibiting the flying-floc of poplar and willow. The plant growth regulator in the technical scheme is applied by a method of injecting the plant growth regulator into the main branch and trunk of the plant.
As a preferable technical scheme, the auxiliary agent comprises a nitrogen fertilizer and a phosphorus-potassium compound fertilizer, and the mass ratio of the nitrogen fertilizer to the phosphorus-potassium compound fertilizer is (1.5-2.5): (3-5).
As a preferable technical scheme, the nitrogen fertilizer is at least one selected from ammonium sulfate, ammonium bicarbonate, ammonium chloride, ammonia water and liquid ammonia.
As a preferred technical scheme, the nitrogen fertilizer is ammonium sulfate.
As a preferable technical scheme, the phosphorus-potassium compound fertilizer is potassium dihydrogen phosphate.
The inventor adds a certain amount of nitrogen fertilizer in gibberellin GA3, can promote the plant growth and development of poplar and willow, the leaf is dark green, and can with gibberellin synergism, restrain the flower bud differentiation, promote the flower bud to drop, and when nitrogen fertilizer chooseed for use ammonium sulfate, can make direct quick absorption of poplar and willow, but too much nitrogen fertilizer can influence the plant to elements such as calcium, magnesium and potassium and gibberellin GA 3's absorption, nitrogen fertilizer is too little does not play better effect that promotes plant growth again. The inventor finds that by compounding a nitrogen fertilizer with a certain phosphorus-potassium compound fertilizer, the whole components of the plant growth regulator can better promote the growth of plants, can better inhibit flower bud differentiation, reduce the generation of flying catkins of salix populi, and have no inhibiting effect on elements such as calcium, magnesium, potassium and the like. However, the gibberellin GA3 has poor permeability in plants, so that the gibberellin GA3 is unevenly transported in the plants, the inhibition effect on each part of the plants is uneven, the solubility of the gibberellin GA3 in an aqueous solution is poor, the gibberellin GA3 has strong acid-base sensitivity when being used, and the applicability is poor for different use environments. And along with the increase of the inhibition degree of the flower buds of the plants, the resistance capability of the plants is gradually reduced, which is mainly reflected in the poor capability of resisting diseases and pests, resisting drought and resisting cold.
As a preferable technical scheme, the gibberellin powder also comprises a pH regulator and saccharides.
In a preferred embodiment, the pH adjuster is at least one selected from the group consisting of ammonium salts, acetic acid and salts thereof, and citric acid and salts thereof.

The inventor finds that by adding a certain amount of sodium citrate dihydrate, the adaptability of the gibberellin GA3 to acid-base environments can be improved, and the solubility of the gibberellin GA3 in water can also be improved. In particular, the mass ratio of the gibberellin GA3 to the sodium citrate dihydrate is 2:1.9, the optimum effect is obtained.
As a preferable embodiment, the saccharide is at least one selected from the group consisting of monosaccharide, disaccharide and polysaccharide.
As a preferable technical scheme, the saccharide is monosaccharide, and the monosaccharide is glucose monohydrate.
The inventor finds that the addition of a certain amount of monohydrate glucose into gibberellin GA3 can not only improve the drought resistance, cold resistance and resistance to diseases and insect pests of plants, but also promote the wettability of a plant growth regulator at plant injection sites, improve the absorption effect of poplar and willow on the plant growth regulator, and further enable gibberellin GA3 to have the effect of inhibiting flying floc of the whole plant. The monohydrate dextrose as a monosaccharide substance can be well and directly absorbed and utilized by plants, the growth and development of the plants are promoted, the plants are stronger, and the monohydrate dextrose contains more hydroxyl groups, so that the monohydrate dextrose is easy to absorb moisture at an injection position, the injection position is kept moist, and the long-acting absorption of the plants to the plant growth regulator is promoted.
In a preferred embodiment, the cosolvent is at least one selected from alcohols, ethers and alcohol ethers.

As a preferable technical scheme, the cosolvent is a monohydric alcohol, and the monohydric alcohol is methanol.
The inventor finds that the methanol not only can improve the solubility of the gibberellin GA3, but also can play a synergistic effect with the gibberellin GA3, so that the branches and leaves of the plant are more fresh and tender and vigorous, and the drought resistance of the plant can be improved to a certain extent.
In a preferred embodiment, the penetrating agent is selected from one of fatty alcohol-polyoxyethylene ether, alkylphenol ethoxylate, fatty acid-polyoxyethylene ester, polyoxyethylene alkylamine, polyoxyethylene alkylolamide, carboxylate, sulfonate, sulfate, and phosphate.
As a preferable technical scheme, the penetrating agent is a mixture of fatty alcohol-polyoxyethylene ether and sulfonates, and the mass ratio of the fatty alcohol-polyoxyethylene ether to the sulfonates is (3-7): (1-3).
As a preferable technical scheme, the fatty alcohol-polyoxyethylene ether is isomeric tridecanol polyoxyethylene ether.
As a preferable technical scheme, the addition number of the ethylene oxide in the isomeric tridecanol polyoxyethylene ether can be one of 3, 5, 6, 7, 8, 10 and 12.
As a preferable technical scheme, the addition number of ethylene oxide in the isomeric tridecanol polyoxyethylene ether is 8, and specifically isomeric tridecanol polyoxyethylene ether TO8.
In a preferred embodiment, the sulfonate is at least one selected from the group consisting of alkyl benzene sulfonate, α -olefin sulfonate, alkyl sulfonate, α -sulfo monocarboxylic acid ester, fatty acid sulfoalkyl ester, succinate sulfonate, alkyl naphthalene sulfonate, petroleum sulfonate, lignin sulfonate, and alkyl glyceryl ether sulfonate.
As a preferable technical scheme, the succinate sulfonate is succinic acid monoester sulfonate and/or succinic acid diester sulfonate.
As a preferable technical scheme, the succinic acid diester sulfonate is dioctyl sodium sulfosuccinate.
As a preferable technical solution, the sulfonate is sodium diisooctyl succinate sulfonate.
In order to improve the permeability of the plant growth regulator, the inventor adds a certain amount of dioctyl sodium sulfosuccinate into gibberellin powder, and finds that the dioctyl sodium sulfosuccinate can better improve the solubility and stability of gibberellin GA3 in water, improve the permeation effect of the plant growth regulator, enable the plant growth regulator to wet the application positions of poplar and willow, enable the plant growth regulator to quickly permeate into the interior of the plant, enable the plant growth regulator to be smoothly transported to each branch part of the plant through a catheter in the branch part, and transport the plant growth regulator to each part through a catheter in the branch part or through a cell membrane transfer mode. The inventors have found that plant growth regulators are better transported from the site of application to the branches of the plant, but are less effective when transported from the branches to smaller shoots. The inventor believes that the possible reason is that the plant growth regulator is transported in the plant body through the main conduit from the application position to each branch position, the plant growth regulator is transported more smoothly in the main conduit due to the fact that the cavity of the main conduit is larger, but the plant growth regulator is transported through a smaller conduit or a cell membrane from the branch position to the smaller branch position, and the sodium diisooctyl succinate sulfonate has higher viscosity, so that the viscosity of the plant growth regulator is increased, and the transfer efficiency of the plant growth regulator between the cell membranes is weakened. The inventor finds that the dioctyl sodium sulfosuccinate can reduce the high-temperature resistance of the plant growth regulator, has lower drug effect when the plant growth regulator is used at higher temperature, and reduces the high-temperature stability of the plant growth regulator during storage. The inventor unexpectedly finds that when the isomeric tridecanol polyoxyethylene ether, in particular the addition number of ethylene oxide in the isomeric tridecanol polyoxyethylene ether is 8, is added into the plant growth regulator, the plant growth regulator not only has better permeability and transportability in the whole plant, but also further improves the solubility of gibberellin GA3 and improves the high-temperature resistance stability of the whole plant growth regulator. However, when the addition amount of ethylene oxide in the isomeric tridecanol polyoxyethylene ether is too small, the high temperature resistance of the plant growth regulator is not well improved, and when the addition amount of ethylene oxide in the isomeric tridecanol polyoxyethylene ether is too large, the solubility of gibberellin GA3 in water is reduced. The inventors considered that the possible reason is that the hydrophilic group in the dioctyl sodium sulfosuccinate has a small force with water, the water molecules and the rest molecules move vigorously when the temperature is increased, the hydrophilic group in the dioctyl sodium sulfosuccinate is separated from the water molecules, and the collision probability between the dioctyl sodium sulfosuccinate micelles is increased when the temperature is higher, so that the dioctyl sodium sulfosuccinate micelles aggregate with each other to generate sedimentation, thereby reducing the high temperature stability of the plant growth regulator. The heterogeneous tridecanol polyoxyethylene ether has good high temperature resistance, and heterogeneous tridecanol polyoxyethylene ether micelles can be inserted between dioctyl sodium sulfosuccinate micelles, so that aggregation among the dioctyl sodium sulfosuccinate micelles is reduced, the sedimentation phenomenon is reduced, and the high temperature resistance stability is improved. And the isomeric tridecanol polyoxyethylene ether has fewer branched chains and smaller steric hindrance, and can be smoothly transferred between cell membranes, so that the plant growth regulator can be uniformly and smoothly transported to each part of a plant. And the addition of the isomeric tridecanol polyoxyethylene ether can also improve the dilution stability of the plant growth regulator, and the plant growth regulator still has better stability when being diluted to 20 times by using hard water, and can not generate turbidity and precipitation. However, the plant growth regulator easily foams more during storage, transportation and use due to the addition of the penetrant.
As a preferred technical scheme, the defoaming agent is alcohols and/or organic silicon.
As a preferable technical scheme, the defoaming agent is a silicone defoaming agent.
The inventor finds that the foaming phenomenon of the plant growth regulator can be well inhibited and the high-temperature resistance of the whole plant growth regulator can be improved by adding a certain amount of organic silicon defoaming agent. However, the plant growth regulator has poor low temperature stability, and at a lower temperature, the plant growth regulator is crystallized and turbid, so that the usability of the plant growth regulator is reduced.
As a preferable technical scheme, the antifreezing agent is alcohol, and the carbon chain length of the alcohol is C2-C8.
As a preferred technical scheme, the antifreezing agent is 1, 2-propylene glycol.
In a second aspect of the present invention, there is provided a method for preparing said plant growth regulator, comprising at least the steps of:
(1) Adding water and gibberellin powder into a mixing and stirring kettle, and stirring to obtain a mixture A;
(2) Adding a cosolvent, an antifreeze, a penetrating agent and a defoamer into the mixture A, stirring and filtering to obtain the composite material.
Has the advantages that:
the inventor uses gibberellin as a main effective component of a plant growth regulator, the gibberellin can promote the growth and development of poplar and willow, can well inhibit the flower bud development of the poplar and willow to differentiate the flower bud into leaf bud, and the gibberellin has the effect of flower thinning and fruit thinning when acting on the poplar and willow, so that the differentiated flower bud falls off, and the formation of flying catkins of the poplar and willow is inhibited. In the technical scheme, the inventor adds the penetrating agent to promote the penetrating effect and the speed of the plant growth regulator on the plant body, improve the absorption and the utilization of the plant to the plant growth regulator and further improve the inhibition effect and the stability of the willow flying catkin.
