Technical Field
The invention is suitable for the technical field of fertilizer preparation, and provides a fertilizer containing plant polyphenol and a preparation method thereof.
Background
Plant polyphenol is a secondary metabolite of plants, widely exists in leaves, shells, pulp and seed coats of plants, and mainly comprises lignin, tannin, flavonoids and the like. Common plant polyphenols include tea polyphenols, grape polyphenols, apple polyphenols, etc., and polyphenols have astringency, can cause dyspepsia of plant eating pests, can influence reproduction of pests, and reduce survival rate. The synergistic effect of polyphenol substances and polyphenol oxidase can inhibit the stress of soil acidity and heavy metals on plants, so that the plants grow normally in adverse circumstances. The polyphenol structure of the plant polyphenol can be used for inactivating the activity of heavy metals in soil and carrying out organic chelation with trace element fertilizer.
The plant polyphenol can be chelated with other microelements such as Zn, cu, mn and the like, and can effectively solve the problem that the yield of crops is reduced due to the lack of microelements in the growing and developing process. The plant polyphenol has wide functions of antioxidation, antibiosis, disease resistance and the like, is a natural organic matter, is easy to biodegrade, does not have environmental risk, and is not widely applied in the field of crop planting at present.
Therefore, development of a plant polyphenol water-soluble fertilizer which can promote crop growth and increase crop yield is needed.

Further, the preparation method of the plant polyphenol stock solution comprises the following steps:
(1) cleaning at least one of tea tree branches and leaves, apples, grape skin and seaweed, drying and pulverizing;
(2) adding the plants treated in the step (1) into ethanol solution for ultrasonic leaching, centrifuging and filtering;
(3) adding the ultrasonic leaching extract obtained in the step (2) into macroporous resin for adsorption;
(4) washing the macroporous resin adsorbed in the step (3) with water, then desorbing the adsorbed macroporous resin with ethanol solution, and collecting desorption liquid;
(5) and (3) removing ethanol in the desorption liquid in the step (4) to obtain plant polyphenol stock solution.
A preparation method of a fertilizer containing plant polyphenol comprises the following steps:
(1) firstly adding water into a stirring tank, starting stirring and adding plant polyphenol stock solution until the plant polyphenol stock solution is completely dissolved, and obtaining plant polyphenol solution;
(2) adding glucose into the plant polyphenol solution while stirring until the glucose is completely dissolved, so as to obtain a mixed solution A;

(4) and adding rhamnolipid into the mixed solution B while stirring until the rhamnolipid is completely dissolved, so as to obtain the water-soluble fertilizer containing plant polyphenol.
The plant polyphenol stock solution can enhance plant root system development, improve soil environment, and improve soil ventilation and water retention capacity, thereby increasing the activity of plant root systems, promoting nutrient absorption and metabolism of crops, and increasing the yield and quality of crops.
The alginic acid has the functions of enhancing the efficacy and fertilizer efficiency, relieving the phytotoxicity and fertilizer injury, improving the soil environment, improving the stress resistance of crops, improving the quality and the quality of crops and improving the utilization rate of the modifier.
The sugar alcohol has moisture keeping effect, and can prevent leaf from being burnt due to topical concentration of micronutrient, and improve stress resistance of plant.
Glucose, as an organic substance, can provide nutrients that provide conditions for the formation of microbial metabolites. The metabolites of the microorganisms can be stabilized in the soil to form new organic matters, which is beneficial to soil improvement and fertility improvement.
Rhamnolipids have good biodegradability and excellent surface activity, and dissolve various substances in a solution, so that they are more uniformly dispersed in the solution, thereby improving the speed and dissolution rate of dissolution reaction.
The invention aims to provide a fertilizer containing plant polyphenol, which has the following beneficial effects:
(1) the raw materials have wide sources, the used raw materials are green and pollution-free, and substances harmful to crops and the surrounding environment are not generated after the raw materials are completely decomposed.
(2) Enhancing plant root system development, improving soil environment, improving soil air permeability and water retention capacity, thereby increasing plant root system activity.
(3) Can promote nutrient absorption and metabolism of crops and increase the yield and quality of crops.

The implementation effects are shown in Table 1:
as can be seen from Table 1, the area where the fertilizer of the present invention is used has high tomato yield, high sweetness and small pest ratio, and the main reasons may be as follows, and as can be seen from the analysis of comparative example 1, the plant polyphenol stock solution is added in the examples to improve the adaptability of crops to the environmental stress, so that the survival rate of the crops is improved, the plant polyphenol can promote the growth and development of the crops, increase the leaf area and root system development degree of the crops, improve the photosynthesis efficiency of the crops, and the pest reproduction is affected and the pest survival rate is reduced due to the dyspepsia of the plant pests caused by the convergence of the polyphenol.
Of course, the present invention is capable of other various embodiments and its several details are capable of modification and variation in light of the present invention, as will be apparent to those skilled in the art, without departing from the spirit and scope of the invention as defined in the appended claims.
