Water-soluble organic fertilizer containing medium trace elements and preparation method thereof

Abstract

The invention relates to water-soluble organic fertilizer containing medium trace elements and a preparation method thereof, which are applied to the field of agriculture and forestry production. The water-soluble organic fertilizer comprises organic matters, major elements and the medium trace elements. Compared with other fertilizer, the water-soluble organic fertilizer achieves two functions of soil amelioration and plant growth promotion, has the advantages of fast fertilizer efficiency, long fertilizer efficiency, comprehensive and balanced nutrition and the like, and is simple and convenient to apply; and in addition, the water-soluble organic fertilizer is completely water-soluble and adopts complete ionic states, and is convenient to be absorbed and utilized by the plants directly. The water-soluble organic fertilizer takes organic fertilizer as a raw material, wherein yeast grows to form mother liquor after cane molasses fermented, and the mother liquor is processed through spray drying so as to form the organic fertilizer; NPK (Nitrogen, Phosphorus and Potassium) and the medium trace elements are added in the material according to certain standard proportions, and a dose of plant-growth regulators and ion keeping agent are added in the material; and finally, the water-soluble organic fertilizer containing both the organic matters and the inorganic nutrition can be produced after full and uniform mixing. The water-soluble organic fertilizer takes the cane molasses, that is an industrial byproduct, as the raw material, and changes waste into valuable; the material is convenient to get; the operation is simple; the requirements on temperature and humidity are low; and the manufacturing cost is low.

Description

technical field [0001] The invention relates to a water-soluble organic fertilizer containing medium and trace elements, and also relates to a preparation method of the fertilizer. Background technique [0002] Chemical fertilizers (chemical fertilizers for short) include inorganic fertilizers and organic fertilizers; they can be divided into solid fertilizers and liquid fertilizers in terms of morphology. Fertilizers play a significant role in increasing the yield of crops and are an indispensable factor of production in modern agriculture. However, long-term use of inorganic fertilizers can easily lead to a decline in soil fertility, which not only destroys the acid-base balance of the soil, but also leads to problems such as soil acidification, salinization, and compaction; Although the use of organic fertilizers can replace inorganic fertilizers for the production of pollution-free products, improve soil fertility and improve crop quality, but organic fertilizers are sl...

Problems solved by technology

However, long-term use of inorganic fertilizers can easily lead to a decline in soil fertility, which not only destroys the acid-base balance of the soil, but also leads to problems such as soil acidification, salinization, and compaction;

Although the use of organic fertilizers can replace inorganic fertilizers for the production of pollution-free products, improve soil fertility and improve crop quality, but organic fertilizers are slow in fertilizer efficiency and crop yields are not high. If you want to increase crop yields, you must increase the use of organic fertilizers.

However, organic fertilizer resources are limited, which is far from meeting the development needs of modern agriculture. Therefore, fertilizer products containing both organic matter and organic nutrition have become an inevitable development trend.
