Water flush fertilizer containing chitosan oligosaccharide

Abstract

The invention relates to the field of agriculture, in particular to a water flush fertilizer containing chitosan oligosaccharide. The water flush fertilizer consists of the following components in percentage by weight: 20-35% of amino acid raw powder, 10-20% of calcium nitrate dehydrate, 5-15% of monopotassium phosphate, 0.1-0.5% of chitosan oligosaccharide, 3-8% of iron vitriol, 1-5% of zinc sulfate heptahydrate, 1-5% of boric acid, 15-30% of potassium nitrate, 3-8% of urea and 0.01-0.05% of brassinolide. According to the water flush fertilizer provided by the invention, chitosan oligosaccharide is innovatively added into the water flush fertilizer, so that nutrition can be provided to plants continuously, the action time is long, different essential growth periods of the plants can be promoted, the environment is not affected, effective protecting films can be formed on the surfaces of the plants, and the anti-disease property and the resistance of the plants are improved.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to a fertilizer containing chitosan oligosaccharides. 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 f...

Problems solved by technology

[0003] Existing fertilization is rich in trace elements, but this will hinder the growth and metabolism of the plant itself. The trace elements needed by plants can be produced by promoting the growth and metabolism of plants, but they will be lost when fertilization is applied. Cause plants to passively absorb too much trace elements, resulting in waste of fertilizers

[0004] At the same time, general fertilization, such as: fertilization containing amino acids, fertilization containing humic acid, fertilization containing a large amount of elements, etc., can supplement various nutrients of plants, but few can be absorbed and utilized by plants. There are some diseased plants that need to supplement nutrients, not all have normal capillary roots that can absorb nutrients

The reason is that plants cannot absorb it. Although the nutrients in fertilization are sufficient, the number of roots of plants is limited and cannot be absorbed in a short period of time. Especially for diseased plants, the roots are even more deficient and absorb less nutrients. The nutrients in fertilization permeate downwards with the water, farther and farther away from the roots of the plants, and the plants cannot absorb them for a long time
