In the present invention, urea is the nitrogen fertilizer with the highest nitrogen content at present. Nitrogen is one of essential nutrients for plant growth, the content of chlorophyll is reduced due to nitrogen deficiency, leaves are changed from green to light yellow to cause premature senility, and the increase of nitrogen fertilizer can promote plants to synthesize more protein and chlorophyll, enhance the photosynthesis assimilation ability and facilitate the formation of yield.

The regulating raw materials and the nutritional raw materials are compounded, wherein the soybeans are induced to bloom through forchlorfenuron, alpha-sodium naphthalene acetate and sodium phenylpeptide amine acid, and the flowers and the fruit pods are prevented from falling off. The nutrient elements required by the growth of soybean plants are supplemented by potassium dihydrogen phosphate, urea and ammonium molybdate. In addition, after the compound sodium nitrophenolate is compounded with the nutrient elements, the absorption of the soybean plants to the nutrient elements is enhanced, and the yield is favorably formed. Therefore, the substances are applied in a matching way, so that the effect of the regulator can be better played, the effects of promoting flowers and keeping pods are achieved, and the yield of the soybeans is further improved.

The above-mentioned raw materials are distinguished herein by a first component and a second component according to the solubility of the above-mentioned components, wherein the components such as urea, ammonium heptamolybdate, potassium dihydrogen phosphate, sodium nitrophenolate, sodium phenylpeptide aminate and sodium alpha-naphthylacetate are all dissolved in water, and thus, the above-mentioned components are mixed with water herein to form a first solution. In the application, water is adopted to dissolve the components, so that the cost can be saved, and all the components can be dissolved together. While forchlorfenuron is insoluble in water and soluble in ethanol, therefore, forchlorfenuron is mixed with alcohol to form a second solution in the present application. Preferably, the alcohol in the present application is absolute ethanol.

Further preferably, the raw materials comprise, by weight: 400-70 parts of urea, 45-70 parts of ammonium heptamolybdate, 110-130 parts of monopotassium phosphate, 0.5-0.7 part of compound sodium nitrophenolate, 12-18 parts of sodium phenylpeptide aminate, 6-8 parts of forchlorfenuron and 1.2-1.8 parts of alpha-sodium naphthylacetate.
In the application, regulating substances and nutrient elements are compounded to achieve the effects of promoting flowers and protecting pods. The method prevents the flower and fruit pod from falling off by inducing the soybean to bloom by utilizing forchlorfenuron, alpha-sodium naphthalene acetate and sodium phenylalanine. The nutrient elements required by the growth of soybean plants are supplemented by potassium dihydrogen phosphate, urea and ammonium molybdate. In addition, after the compound sodium nitrophenolate is compounded with the nutrient elements, the absorption of the soybean plants to the nutrient elements is enhanced, and the yield is favorably formed. Therefore, the substances are applied in a matching way, so that the effect of the regulator can be better played, the effects of promoting flowers and keeping pods are achieved, and the yield of the soybeans is further improved.
In a second aspect, the application provides a preparation method of the soybean flower and pod promoting and controlling agent, which comprises uniformly mixing the raw materials.
Because the solubility of the raw materials is different in the application, in the specific mixing, the following are adopted:

dissolving forchlorfenuron in ethanol to obtain a second solution;
and uniformly mixing the first solution and the second solution.
The whole preparation method is simple, and the dissolution properties of all raw materials are combined, so that the finally obtained soybean flower and pod promoting control agent is uniformly mixed, and the subsequent spraying process is facilitated.
In addition, the application also provides an application method of the soybean flower and pod promoting and preserving regulator, which comprises the step of spraying the soybean flower and pod promoting and preserving regulator on the leaf surfaces of soybeans.
Specifically, the soybean flower and pod promotion and protection regulating agent is diluted by 100-fold and 150-fold (specifically, the total mass percentage concentration of the regulating raw material and the nutrient raw material in the spraying liquid is 0.23-0.45%), and foliage spraying is carried out for 2 times in total during the period from the initial flowering stage to the full flowering stage and the period from the initial pod stage to the full pod stage of the soybeans; wherein the interval between the first flowering stage and the full flowering stage and between the first pod stage and the full pod stage is about 15-25 days. The amount of the soybean flower promoting and pod keeping regulator is 20-25L per mu. The spraying is carried out at about 4 o' clock in the afternoon of a sunny day, and the quantity is reduced and the spraying is supplemented within 12 hours after the spraying. Cannot be used in combination with herbicides. Since herbicides are mostly acidic or basic substances, which affect the effect of the soybean pod-promoting regulator in the present application, they cannot be applied in combination.
In the application, the foliar spraying is carried out for 2 times in total during the period from the initial flowering stage to the full flowering stage and the period from the initial pod stage to the full pod stage of the soybean, so that the plant can be induced to bloom, and flower and pod protection is carried out on flower buds and fruit pods of different nodes, therefore, the invention has better flower and pod protection effect, and finally, the number of single-plant pods can be increased by more than 20%, the number of single-plant seeds can be increased by more than 15.0%, and the yield can be increased by more than 15.0%. The regulating agent has obvious effects of promoting flowering, protecting pods and increasing yield, and has very wide application prospect in soybean production.

As can be seen from the above table, the yields of the direct mixing of all the raw materials (comparative example one), the deletion of sodium phenoxide (comparative example two), the replacement of sodium phenoxide with choline chloride (comparative example three), the deletion of sodium nitrophenolate (comparative example four) are significantly lower than the treatment of example one. From the above table, it can be calculated that the yield of example one is increased by 6.16% compared to comparative example 1, 10.73% compared to comparative example 2, 7.68% compared to comparative example 3, and 5.21% compared to comparative example 4.
To sum up, the effect of promoting flowers and protecting pods is achieved by compounding the regulating substances and the nutrient elements in the application. The method is characterized in that the flowering of soybeans is induced by using forchlorfenuron, alpha-sodium naphthalene acetate and sodium phenylalanine, so that the shedding of flowers and fruit pods is prevented. The nutrient elements required by the growth of soybean plants are supplemented by potassium dihydrogen phosphate, urea and ammonium molybdate. In addition, after the compound sodium nitrophenolate is compounded with the nutrient elements, the absorption of the soybean plants to the nutrient elements is enhanced, and the yield is favorably formed. Therefore, the substances are applied in a matching way, so that the effect of the regulator can be better played, the effects of promoting flowers and keeping pods are achieved, and the yield of the soybeans is further improved. The preparation method provided by the application is simple, and the dissolution properties of all raw materials are combined, so that the finally obtained soybean flower and pod promoting and protecting regulating agent is uniformly mixed, and the subsequent spraying process is facilitated.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
