Problems solved by technology

At present, there are many kinds of organic fertilizers on the market, and most of the organic fertilizers are mainly prepared from animal feces through fermentation, such as a high-efficiency general-purpose organic fertilizer disclosed in Chinese patent 201310454388. Fertilizer and its preparation method, Chinese patent 201310456255.4 discloses a kind of rapeseed organic fertilizer, etc. In the above-mentioned technologies, it is simple to use livestock manure or domestic organic waste to prepare organic fertilizer. This type of compost will also bring environmental pollution and agricultural products. The reason for the decline in quality is that the feces of livestock contain harmful chemicals such as growth hormones and antibiotics that are input into feed, and these substances will also remain in agricultural products through fertilizers, especially in fast-growing vegetables. It not only endangers human health, but also increases difficulties for the export of agricultural products in our country.

Embodiment 1

[0022] The preparation method of the organic fertilizer involved in the present embodiment comprises three steps of anaerobic fermentation process, aerobic fermentation process and organic fertilizer production:

[0023] (1) Anaerobic fermentation process: Soybean meal, rice bran, fish meal, bacteria, brown sugar, starter, and water are respectively adjusted to 320-350, 20-30, 380-400, 20-30, 20-30, 1- 2 and 200-210 parts by weight are mixed, fully stirred, and placed in a closed container for anaerobic fermentation, and anaerobic fermentation products are obtained after 2-3 days; the water content of the soybean meal, rice bran, and fish meal are all 10-15%, the water content of the brown sugar is 3-5%, and the bacteria include lactic acid bacteria, yeasts, anaerobic actinomycetes and / or photosynthetic bacteria, etc.; the fermentation process It can preserve nutrients and decompose harmful substances in raw materials to increase the content of anaerobic microorganisms;

Embodiment 2

[0027] The composition and preparation method of the organic fertilizer involved in this embodiment are the same as in Example 1; the organic fertilizer involved can be used as a straw decomposing agent, and inserting this product in the straw can promote the decomposition of the straw and make it into an organic fertilizer, or the organic fertilizer of the present invention can be used The products directly buried in the soil together with the straw can increase the ground temperature, and the released gas can also play the role of carbon dioxide fertilization in the greenhouse; as a composting primer, it can promote the decomposition of cellulose and lignin and generate high temperature , kill harmful organisms, decompose toxic substances, increase microbial diversity, and promote nutrient effectiveness, etc. The specific use effects are as follows: figure 2 shown.

Embodiment 3

[0029] The composition and preparation method of the organic fertilizer involved in this embodiment are the same as in Example 1; the organic fertilizer involved can be used as a garbage reducer, and this product can be added to daily life garbage, which can promote the decomposition of organic matter, degrade harmful substances, eliminate peculiar smell, and produce organic fertilizer; as a sewage purifier, this product and clay are mixed evenly by weight percentage 3-5:95-97 and then made into balls, and placed in a cool place for 3-4 days (such as image 3 Shown) the whole body of the spheroid is covered with hyphae, which can be used to decompose underwater sludge to purify polluted waters, and can decompose 30 centimeters deep sludge in 2-5 hours through specific use detection.

Abstract

The invention relates to a preparation method of an organic fertilizer. The preparation method comprises three steps: an anaerobic fermentation process, an aerobic fermentation process and an organic fertilizer manufacturing process. The preparation method specifically comprises the steps: in the anaerobic fermentation process, fully stirring soybean meal, rice bran, fish meal, a strain, brown sugar, a starter culture and water which are separately mixed in parts by weight; then performing the aerobic fermentation process; and finally, mixing an anaerobic fermentation product with an aerobic fermentation product in a weight ratio of 3: 1 to prepare an organic fertilizer product. The product is green and environmentally friendly, convenient to use, wide in use, high in output, good in quality and obvious in using effect, the preparation process is simple, the production process is easy to control, and the preparation environment is friendly.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of organic fertilizers, and relates to a method for preparing organic fertilizers by using organic matter such as rice bran and soybean meal as a medium and a carrier, in particular to a method for preparing organic fertilizers. [0003] Background technique: [0004] With the rapid development of modern agriculture, crop yields continue to increase. In agricultural production, "fertilizers" play an important role in increasing production. Agricultural fertilizers are roughly divided into two categories: inorganic fertilizers and organic fertilizers. Inorganic fertilizers are mineral fertilizers, also called chemical fertilizers, referred to as Chemical fertilizer, it has the characteristics of simple ingredients, high active ingredients, easy to dissolve in water, fast decomposition, and easy to be absorbed by roots, so it is called "quick-acting fertilizer". Fertilizers produced by chemical synthesi...
