Organic fertilizer capable of slowly releasing medium trace elements and compound microorganisms and preparation method thereof

Abstract

The invention belongs to the technical field of organic fertilizer preparation, and discloses organic fertilizer capable of slowly releasing medium trace elements and compound microorganisms and a preparation method thereof. The organic fertilizer is prepared from, by mass, 10-15 parts of sodium alginate coating materials, 8-15 parts of solid carrier mixture and 35-50 parts of medium trace elementand compound microorganism organic fertilizer mixtures; the sodium alginate coating materials are sodium alginate-zeolite coating materials. The organic fertilizer can specifically provide medium trace elements needed by growth in the plant growth period, secondary metabolites released in the growth process of compound microorganisms can also be obtained, meanwhile, the slow release effect can beachieved, the fertilizer consumption is lowered, and the disease resistance and cold resistance of plants are improved; the organic fertilizer has the advantages that the plant yield can be obviouslyincreased, the quality can be improved, and the resistance can be improved; the organic fertilizer can be used for one or more types of plants, and particularly used for greenhouse vegetables.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizer preparation, and in particular relates to a slow-release medium trace element and compound microbial organic fertilizer and a preparation method. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Sodium alginate is a polysaccharide polymer extracted and refined from kelp or other algae. It is an odorless, tasteless white or light yellow amorphous powder. It is widely used in the food industry, medical and health, textile industry and other fields due to its excellent properties such as high performance, high safety and degradability. [0004] At present, the current process of industrial extraction of sodium alginate is complicated and the production cost is high, and the products are mainly concentrated in medium and high viscosity products, and the proportion of low viscosity sodium alginate is very small.

Problems solved by technology

[0010] (1) Among the prior art fertilizers, the medium and trace elements that cannot meet the needs of plant growth and several common microorganisms that improve the soil

[0011] (2) Due to the long-term excessive application of chemical fertilizers: environmental deterioration, water pollution, serious soil degradation, compaction, soil fertility decline, aggravated pest damage, decline in the quality of agricultural products, chemical residues in the soil lead to increased serious disease rates, and genetic distortions A series of ecological and economic problems, such as a series of ecological and economic problems, have posed a serious threat to the survival and development of human beings.

However, a single zeolite powder has poor selective adsorption to toxins, heavy metals and other harmful substances, and the removal efficiency of harmful substances is not high, and it is easy to absorb nutrients to reduce the release of nutrients and reduce the utilization rate of fertilizers.
