Description

Technical Field

[0001] The invention belongs to the technical field of fertilizers, and in particular relates to a foliar spray-type silicon fertilizer and a preparation method thereof. Background Art

[0002] Silicon has been confirmed by the international soil science community as the fourth plant nutrient element after nitrogen, phosphorus and potassium. It is an essential nutrient for grasses and root crops. After applying a large amount of nitrogen, phosphorus and potassium fertilizers, the silicon nutrition provided by natural circulation alone is far from enough to make crops grow healthily. Therefore, silicon nutrition has become a limiting factor for plant growth. Scientific supplementation of silicon nutrition has become a hot topic in modern agricultural production. The characteristic of modern agriculture is balanced fertilization. After applying a large amount of nitrogen, phosphorus and potassium fertilizers, the scientific and reasonable application of silicon fertilizers and other trace elements can not only increase crop yield and quality, but also improve the ecological environment. In September 1999, the US Department of Agriculture held the first "Silicon and Agriculture" International Academic Seminar in Florida, marking that silicon fertilizers have received attention from the global agriculture and fertilizer industry.

[0003] Foliar fertilization is a method of fertilizing crops by absorbing nutrients through the leaf surface (including part of the stem surface) by osmotic diffusion. It is an economical and effective fertilization measure. It can strengthen crop nutrition and prevent crop nutrient deficiency, and it is also a good way to improve fertilizer utilization. However, the existing foliar fertilizer cannot be effectively spread and attached to the leaf surface after spraying, which seriously affects the absorption of nutrients by the leaf surface, and it is easy to cause the problem that the foliar fertilizer cannot be effectively utilized. Summary of the invention

[0004] In view of the above-mentioned prior art, the present invention provides a foliar spray-type silicon fertilizer and a preparation method thereof, so as to solve the problem that the existing foliar fertilizer cannot be effectively utilized.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is to provide a foliar spray-type silicon fertilizer, comprising the following components:

[0006] Water-soluble silicon fertilizer, organic silicon additive, amino acid, gibberellin, seaweed extract, zinc sulfate, manganese sulfate, medium element water-soluble fertilizer, surfactant and water;

[0007] 1L of foliar spray silicon fertilizer includes: 0.4-0.8g silicon, 0.5-1g silicone additive, 1-3g amino acid, 1-3g gibberellin, 0.5-2g seaweed extract, 3-5g zinc sulfate, 3-5g manganese sulfate, 3-6g medium element water-soluble fertilizer, and 0.5-1g surfactant;

[0008] Seaweed extract is prepared by the following steps:

[0009] S1: mixing fresh seaweed and water in a mass ratio of 1:1 to 3, and then preparing the mixture into a slurry;

[0010] S2: adding a composite enzyme accounting for 1 to 3% of the mass of the slurry to the obtained slurry, and performing enzymolysis at 35 to 45° C. for 3 to 6 hours to obtain an enzymatic hydrolysis system; the composite enzyme includes cellulase, xylanase and pectinase;

[0011] S3: the enzymatic hydrolysis system is mixed with a 75% ethanol solution in a volume ratio of 1:2 to 5, stirred for 10 to 20 minutes, and then centrifuged to collect the upper solution;

[0012] S4: Concentrate and dry the collected solution to obtain.

[0013] Based on the above technical solution, the present invention can also be improved as follows.

[0014] Furthermore, based on 1L of foliar spray-type silicon fertilizer, it includes: 0.5g of silicon, 0.5g of silicone additive, 2g of amino acid, 2g of gibberellin, 1g of seaweed extract, 4g of zinc sulfate, 4g of manganese sulfate, 4g of medium element water-soluble fertilizer, and 0.8g of surfactant.

[0015] The beneficial effects of the present invention adopting the above technical solution are:

[0016] The foliar spray silicon fertilizer of the present invention contains water-soluble silicon fertilizer as the main active ingredient. The water-soluble silicon fertilizer is attached to the leaves of crops during spraying and can be effectively absorbed by the crops, thereby improving the utilization rate of the silicon fertilizer.

[0017] Amino acids are also added to the silicon fertilizer of the present invention. Amino acids can form complexes with silicon in water-soluble silicon fertilizers to increase the solubility of silicon in water, thereby improving the absorption efficiency of silicon by plants. At the same time, amino acids can serve as transport carriers of silicon to transport silicon from the leaf surface to other parts of crops, thereby promoting the distribution and utilization of silicon in crops. In addition, amino acids can promote the utilization and conversion of silicon by plants by regulating the metabolic pathways in crops, thereby improving the stress resistance and yield of crops.

[0018] The silicon fertilizer of the present invention also contains gibberellins, which are a broad-spectrum plant growth regulator that can promote the elongation of crop stems and the expansion of leaves, and also has a promoting effect on the improvement of leaf stomatal conductance, thereby improving the photosynthesis of crops; at the same time, gibberellins have a regulating effect on the structure and function of crop cell walls, which helps the deposition and fixation of silicon in crop cell walls, thereby improving the absorption and utilization efficiency of silicon by crops.

[0019] The silicon fertilizer of the present invention is also added with seaweed extract, which is rich in seaweed polysaccharides and other substances, which can increase the viscosity of the sprayable silicon fertilizer, so that the silicon fertilizer can be better attached to the crop leaves and is not easily washed away by wind and rain, thereby improving the utilization rate of the silicon fertilizer; moreover, the active substances in the seaweed extract, such as vitamins, minerals, etc., can promote the metabolic activities of plant leaves and improve the leaves' ability to absorb nutrients, which helps the nutrients in the silicon fertilizer to be better absorbed and utilized.

[0020] The silicon fertilizer of the present invention is also added with a water-soluble fertilizer of a medium amount of elements, which can directly provide elements such as calcium and magnesium to crops, meet the needs of crops for the medium amount of elements, and promote the normal growth and development of crops.

[0021] The silicon fertilizer of the present invention also contains surfactants and organosilicon additives, and the interaction between the two can effectively spread the sprayable silicon fertilizer of the present application on the leaf surface, which is beneficial for the crop leaves to absorb the effective ingredients.

[0022] Furthermore, the water-soluble silicon fertilizer is sodium silicate, potassium silicate, sodium disilicate or sodium metasilicate; and the organosilicon additive is polyether modified silicone oil IOTA2000.

[0023] Furthermore, the medium element water-soluble fertilizer is citric acid chelated copper.

[0024] Furthermore, the surfactant is sodium dodecylbenzene sulfonate or sodium fatty alcohol polyoxyethylene ether sulfate.

[0025] Furthermore, the complex enzyme is prepared by mixing cellulase, xylanase and pectinase in a mass ratio of 10:1 to 3:5 to 6.

[0026] Furthermore, the enzymatic hydrolysis temperature in S2 is 40°C and the enzymatic hydrolysis time is 5 h.

[0027] The present invention also discloses a method for preparing the foliar spray-type silicon fertilizer, comprising the following steps:

[0028] (1) dissolving a formulated amount of water-soluble silicon fertilizer, amino acid, gibberellin, zinc sulfate, manganese sulfate and medium element water-soluble fertilizer in water to form a base solution;

[0029] (2) 5 to 10 minutes before spraying, dissolve the formulated amount of silicone additives, seaweed extracts and surfactants into the base liquid and mix well.

[0030] The beneficial effects of the present invention are as follows: the foliar spray silicon fertilizer in the present invention comprises a plurality of components, which work together to provide sufficient nutrition for crops and effectively promote the growth of crops. In addition, the amino acids in the components can chelate with silicon and transport it, which can effectively improve the absorption and utilization of silicon by crops; the seaweed extracts in the components can make the foliar fertilizer stably adhere to the surface of crop leaves, which can avoid the waste of foliar fertilizer; and the surfactants and organosilicon additives in the components can promote the spreading of foliar fertilizer on the surface of crop leaves, so that the leaves can better absorb the nutrients in the foliar fertilizer. That is, the nutrients in the foliar spray silicon fertilizer in the present application can be fully utilized by crops, and the utilization rate of foliar fertilizer can be improved.
