Composite seaweed fertilizer and preparation method thereof

Abstract

The invention discloses a composite seaweed fertilizer and a preparation method thereof. The composite seaweed fertilizer comprises raw materials and auxiliary materials. The fertilizer is prepared from the following raw material components in parts by weight: 7-9 parts of seaweed, 5-7 parts of algae residues, 6-8 parts of microalgae residues, 4-6 parts of ascophyllum nodosum, 1-3 parts of Ecklonia kurome, 4-6 parts of kelp, 3-5 parts of gulfweed, 2-4 parts of Chewangzao, 2-4 parts of desert algae, 2-4 parts of Rhodomelaceae, 3-5 parts of fucus, 1-3 parts of enteromorpha, 1-3 parts of Ulva lactuca, 3-5 parts of Kappaphycus, 3-5 parts of brown algae, 2-4 parts of citrus peel residues, 1-3 parts of zeolite, 4-6 parts of shells and 4-6 parts of urea. According to the composite seaweed fertilizer and the preparation method thereof, compared with an organic fertilizer, thec omposite seaweed fertilizer use algae as main raw material, the cost can be effectively reduced, the environment optimization effect can be achieved, the manufacturing method changes a traditional evaporation and concentration process, energy consumption is reduced, and through the processes of drying, cooling, reacting, fermenting and the like, the composite seaweed fertilizer has the advantages that various nutrients in the algae are fully used, the cost is conveniently reduced, the application range of the seaweed fertilizer is widened, the environment is effectively protected and the like.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a compound seaweed fertilizer and a preparation method thereof. Background technique [0002] Seaweed fertilizer is a kind of fertilizer produced and processed by marine brown algae or mixed with a certain amount of nitrogen, phosphorus, potassium and medium and trace elements. Seaweed fertilizer is a kind of fertilizer produced and processed by marine brown algae or mixed with certain It is a kind of fertilizer processed from a large amount of nitrogen, phosphorus, potassium and medium and trace elements. It has various forms. The market is mainly liquid and powder, and a small part is in granular state. Seaweed fertilizer uses marine plant seaweed as the main raw material. Bio-fertilizers made through scientific processing, the main components are natural bioactive substances extracted from seaweed that are beneficial to plant growth and mineral nutrients absorbed by seaweed and enri...

Problems solved by technology

[0005] With the development of society, organic fertilizers are produced through chemical processes, which have great harm to the environment. However, without using fertilizers, the elements contained in the soil will be reduced, which is not conducive to the growth of plants. The use of organic fertilizers will cause harm to a certain extent. The soil causes eutrophication, which reduces the production efficiency of plants, and may also cause soil damage and become barren. At present, most of the seaweed fertilizers on the market are produced with brown algae as a single raw material. Although the alginic acid contained in brown algae has been proved to be a A natural soil conditioning substance, which can promote the formation of soil aggregate structure, improve the internal pore space of the soil, increase the ability of soil to retain fertilizer, water and gas, quickly restore the colloidal balance of the soil, and increase the biological vitality of the soil. However, the total amount of brown algae appears to be It is relatively low, which is not conducive to production. Even if the cost of the produced seaweed fertilizer is relatively high, it is not conducive to sale, resulting in a decrease in use efficiency. Secondly, the domestic seaweed fertilizer production process mainly uses methods such as physical crushing and chemical extraction to reduce the effective active ingredients in seaweed. More damage, seriously affecting the effect of post-processing fertilizer production
