Water flush fertilizer

Abstract

The invention discloses a water flush fertilizer, the water flush fertilizer comprises, by mass, 20-35% of urea, 17-30% of phosphorus pentoxide, 15-30% of potassium nitrate and 5-30% of alginate oligosaccharide, and the water flush fertilizer has the advantages that: the alginate oligosaccharide is innovatively added into the water flush fertilizer for continuously providing nutrients for plants, the water flush fertilizer is long in effect time, promotes various necessary stages of plant growth cycles, has no impact on the environment, also can form effective protective films on the surface of the plant body, enhances the disease resistance and resistance to tolerance of the plant body.

Description

technical field

[0001] The invention belongs to the technical field of fertilizers, and in particular relates to flush fertilization. Background technique

[0002] Flush fertilization is a fertilizer used with irrigation, which is similar to plant growth regulators and foliar fertilizers, and is also a type of topdressing fertilizer. According to the classification of fertilization, it is different: fertilization can be a macronutrient fertilizer (such as N, P, K, Ca, Mg, etc.), or a micronutrient fertilizer (such as Zn, B, Mn, Fe, Mo, Cu, Cl, etc.) etc.), it can also be organic fertilizer (such as amino acid, humic acid, etc.), or bacterial fertilizer, compound fertilizer, etc. Therefore, in a broad sense, fertilization is not a special fertilizer, but only a method of application. The fertilizer applied is called flush fertilization. In a narrow sense, with the development of modern science and technology, especially the development of the chemical fertilizer industry, f...

Examples

Embodiment 1

[0009] Embodiment 1: The fertilization formula of the present invention includes 20% of urea, 17% of phosphorus pentoxide, 15% of potassium nitrate, and 5% of seaweed oligosaccharides, all of which are percentages by mass. The molecular weight is 3-5KDA.

[0010] The above seaweed oligosaccharides are extracted from alginic acid, alginate, alginate derivatives or raw seaweed.

[0011] The above-mentioned original seaweed includes one or more of kelp, macroalgae and sargassum.

[0012] In order to illustrate the yield-increasing effect of fertilization by flushing of the present invention, the present invention has done a large amount of comparative experiments, adopts fertilization by flushing of the present invention and existing fertilization by flushing to do yield increase contrast in the test field, chooses plant test fields such as cucumber, Chinese cabbage, capsicum, and fertilization by flushing of the present invention The average yield increase rate of the test fiel...

Embodiment 2

[0013] Embodiment 2: The fertilization formula of the present invention includes 35% urea, 30% phosphorus pentoxide, 30% potassium nitrate, and 30% seaweed oligosaccharides, all of which are percentages by mass. The molecular weight is 3-5KDA.

[0014] The above seaweed oligosaccharides are extracted from alginic acid, alginate, alginate derivatives or raw seaweed.

[0015] The above-mentioned original seaweed includes one or more of kelp, macroalgae and sargassum.

Embodiment 3

[0016] Embodiment three: the fertilization formula of the present invention, the fertilization includes 25% urea, 25% phosphorus pentoxide, 25% potassium nitrate, and 25% seaweed oligosaccharides, all of which are percentages by mass. The molecular weight is 3-5KDA.

[0017] The above seaweed oligosaccharides are extracted from alginic acid, alginate, alginate derivatives or raw seaweed.

[0018] The above-mentioned original seaweed includes one or more of kelp, macroalgae and sargassum.
