Description

High-efficiency biologically active organic fertilizer and preparation method thereof

The invention relates to an efficient biologically active organic fertilizer and a preparation method thereof. Background technique '

At present, the application of long-acting fertilizers and bio-organic fertilizers is becoming more and more common. In particular, bio-organic fertilizers are popular due to their environmentally friendly, high fertilizer utilization rate, and improved crop quality. However, bio-organic fertilizers currently on the market Fertilizer efficiency is generally low, or a large amount of inorganic fertilizers are mixed. Summary of the Invention

Therefore, the object of the present invention is to provide a highly effective bioactive organic fertilizer, which has the advantages of strong fertility and long-lasting fertilizer effect, high fertilizer utilization rate, improved soil structure, improved crop quality, increased yield and income, and low cost.

The biological organic fertilizer of the present invention includes the following raw materials in parts by weight:

(A) 30-60 parts by weight of plant straw,

(B) 10-20 parts by weight of meat and bone meal,

(C) 20-50 parts by weight fly ash and / or furnace ash,

(D) 8-20 parts by weight of plant seed cake,

(E) 1 to 10 parts by weight of sesame;

(F) 0-8 parts by weight of oxytetracycline can be added,

And / or (G) optional 5 billion to 50 billion biological bacteria / 100 kg (A) + (B) + (C) + (D) + (E) + (F).

The plant straw is usually a crop straw, such as a sorghum straw, a corn straw, a straw straw, a wheat straw, a soybean straw, or the like, or a mixture thereof. Meat and bone meal can be purchased as a normal feed, for example. The plant seed cake is the dregs left after the use of plant seeds (such as pressing oil, etc.). For example, it can be cottonseed cake, rapeseed cake, peanut cake, tea seed cake, soybean meal, etc., or a mixture thereof. Fly ash is a waste material, for example, it can be obtained from a thermal power plant and used as a raw material to solve the problem of waste disposal at the same time; the furnace ash can be the residue after burning of coal and the like. Oxytetracycline scraps are leftovers from the process of producing oxytetracycline, and it contains culture medium, trace oxytetracycline, etc., which can be obtained from a pharmaceutical factory, for example. The biological bacteria include nitrogen-fixing bacteria, phosphate-dissolving potassium-dissolving bacteria, lactic acid bacteria, etc. or Their mixture.

Of course, the bio-organic fertilizer of the present invention may also include inorganic fertilizers (such as nitrogen fertilizer, potassium fertilizer, phosphate fertilizer, or a mixture thereof), trace elements, and other optional ingredients, although this is not preferred. Among them, the inorganic fertilizer preferably accounts for 5-30 wt% of the entire fertilizer.

The preparation of the biologically active organic fertilizer of the present invention includes the following steps: mixing the above raw materials, and fermenting in a fermentation tank at 50-80 ° C, preferably at 55-70 ° C for 15-72 hours and preferably 20-30 hours, and then Dry, preferably at 40-70 ° C or air-dry, then pelletize and package.

The biological organic fertilizer of the present invention is characterized by a high total bacteria content after fermentation, which can reach more than 300 million per gram, an organic matter content of up to 75% or more, a humic acid content of up to 18%, a scientific formula, a strict process, and a biological organic fertilizer. Contains a large number of nutrients and nitrogen, phosphorus, potassium, and other trace elements and ultra-trace elements required by crops, which can provide crops with various nutrients required for growth and development, promote the formation of auxin in crops, and activate the growth function of plants, especially It is a one-time application of biological iTL fertilizer. From the time of sowing the crop to the time of harvesting, the crop can be deep-rooted without the need for topdressing to ensure high-quality production.

Bio-organic fertilizer is applied to the soil, which increases the content of beneficial bacteria and organic matter. On the one hand, the high-temperature fermentation under the action of bacteria in the soil further decomposes, but the decomposition rate is much slower than during the fermentation process. A large number of microbial cells will gradually release fixed nutrients to be supplied to crops, and the activities of special microorganisms of biological organic fertilizer will convert potential nutrients in the soil into quick-acting nutrients for crops. It can be seen that the nutrients of crops come from the following three aspects: the nutrients of biological fertilizer itself, the nutrients absorbed by microorganisms in fixed fertilizers, and the potential nutrients absorbed by microorganisms in soil.

Due to the large increase and decomposition of organic matter in the soil, the increase in the number of microbial fungi and rapid mass reproduction, the nutrients of the organic matter in the fixed soil are absorbed, and in turn the rapidly multiplying microbial fungi release nutrients to the crop. This process is due to The application of bio-organic fertilizers is repeated cyclically during crop growth. Each fertilizer particle is not only a source of fertilizer applied, but also a source of fermented nutrients in the soil. At the same time, it supplies nutrients to the crops. Therefore, as long as the biological organic fertilizer is applied when the crop is planted, the mature process is no longer necessary. Applying other fertilizers, the fertilizer effect is high, the fertilizer effect is durable and harmless. detailed description
