Description

Technical Field

[0001] The invention relates to the technical field of mineralized bio-organic fertilizers, in particular to a method for preparing the mineralized bio-organic fertilizers. Background Art

[0002] Bio-organic fertilizer is a fertilizer that has the effects of both microbial fertilizer and organic fertilizer. It is made by combining specific functional microorganisms with animal and plant residues (such as livestock and poultry manure, crop straw, etc.), and undergoing harmless treatment and composting. This fertilizer not only contains the advantages of organic fertilizer, but also incorporates the characteristics of microbial fertilizer, making it outstanding in promoting crop growth and improving soil structure.

[0003] The main raw materials of bio-organic fertilizer include agricultural waste, such as livestock and poultry manure, crop straw, etc. Through specific fermentation, deodorization and complete composting processes, these raw materials are converted into organic fertilizers rich in various functional microorganisms and trace elements. This fertilizer can not only provide necessary nutrients for crops, but also improve soil structure, reduce soil compaction, and enhance the soil's water and fertilizer retention capabilities. In addition, after the beneficial microorganisms in the bio-organic fertilizer enter the soil, they will form a symbiotic proliferation relationship with the microorganisms in the soil, inhibit the growth of harmful bacteria, and promote the healthy growth of crops.

[0004] Bio-organic fertilizers have various functions, including providing nutrition, resisting diseases and insects, and improving soil. By adding different bacterial agents, bio-organic fertilizers can be given specific functions. For example, rhizobium fertilizers and nitrogen-fixing fertilizers can provide the nutrients needed by plants; while bio-control agents can inhibit the reproduction of pathogens and improve the disease resistance of crops. In addition, bio-organic fertilizers can also improve the physical and chemical properties of the soil, increase the population of beneficial microorganisms in the soil, thereby improving soil fertility and the crop growth environment.

[0005] When applying biological organic fertilizer, it is necessary to pay attention to maintaining the activity of beneficial microorganisms and avoid adverse conditions such as high temperature, low temperature, flooding, etc. that affect its effect. Scientific and reasonable selection of application types and quantities, as well as correct application methods, are the key to ensuring that biological organic fertilizers can achieve maximum effectiveness. Through the reasonable application of biological organic fertilizers, it can effectively alleviate the obstacles of continuous cropping and reduce environmental pollution. It is an environmentally friendly and efficient agricultural fertilizer choice.

[0006] Minerals are naturally occurring compounds or natural elements in the earth's crust, also known as inorganic salts, and are the general term for inorganic substances in the human body. Minerals are the general term for various elements necessary for the formation of human tissues and the maintenance of normal physiological functions. They are one of the seven essential nutrients for the human body. Minerals cannot be produced or synthesized by the human body itself and must be ingested through diet. Minerals play a vital role in the human body. They not only serve as building materials to form human tissues, but also maintain the normal physiological functions of the human body. There are about 50 kinds of minerals in the human body, of which about 20 are necessary for the formation of human tissues, the maintenance of physiological functions, and biochemical metabolism. These elements can be roughly divided into two categories: major elements and trace elements. Major elements include calcium, phosphorus, potassium, sodium, chlorine, etc., while trace elements include iron, zinc, copper, manganese, iodine, selenium, etc. Therefore, how to add minerals to biological organic fertilizers to make the nutritional elements of biological organic fertilizers richer and more effective has become a new direction for the development of biological organic fertilizers.

[0062] In summary: the present invention proposes a method for preparing a mineralized bio-organic fertilizer. The mineralized bio-organic fertilizer obtained by the proportioning method of Example 1 can not only quickly activate soil microorganisms and accelerate soil air circulation, but also effectively increase the nitrogen content of the soil, which is more conducive to the growth of crops. The mineralized bio-organic fertilizer obtained by the proportioning method of Example 2 increases the fermentation time to 40 days, which will reduce the survival rate of soil microorganisms. The mineralized bio-organic fertilizer obtained by the proportioning method of Example 3 shortens the fermentation time to 30 days, which will reduce the nitrogen content in the soil. The mineralized bio-organic fertilizer obtained by the proportioning method of Example 4 has a ratio of 5:1 between the bio-organic fertilizer and the mineral, which will aggravate the heavy metal pollution of the soil and agricultural products, and cause potential harm to the environment and human health. The mineralized bio-organic fertilizer obtained by the proportioning method of Example 5 has a ratio of 20:1 between the bio-organic fertilizer and the mineral, which cannot give full play to the role of organic fertilizer in improving soil structure and soil fertility, and affects the growth of crops.
