Problems solved by technology

Among them, in addition to the configuration of raw materials, the production process of the agglomerate method and the slurry method also includes several processes such as granulation, drying, cooling, screening, crushing, returning materials, dry and wet treatment of tail gas, and then can enter product packaging. process, the corresponding process is long, the investment occupies a large area, the energy consumption of the production process is high, and it has different impacts on the environment
For melt granulation, since the production process includes metering and mixing of raw materials, heating and melting of raw materials, tower (rotary steel belt) granulation, and cooling process, the corresponding investment occupies a large area and the energy consumption of the production process increases.

Embodiment 1

[0022] A novel fertilizer, which is prepared according to the following method:

[0023] 1) Dry the corn stalks in the sun, then crush them into corn stalk powder with a grinder, add them to the fermenter, then add soybean meal and 80°C water to the fermenter, stir well, and when the temperature drops to 30°C, add the mixed bacteria liquid, under 100 rpm stirring condition, fermented for 36 hours to obtain fermentation liquid; wherein, the mass ratio of corn stalk powder, soybean meal, water and mixed bacterial liquid was 5:2:20:1; Bacillus liquid, Trichoderma harzianum liquid and nitrogen-fixing bacteria liquid were mixed according to the volume ratio of 1:1:1, and the concentrations of the three bacterial liquids were all 2×10 7 Individual / ml; Bacillus subtilis is ATCC6051 (can refer to documents such as CN1831115A); Trichoderma harzianum is ATCC20873 (can refer to documents such as CN1901797 A); Torus azotobacter is ATCC4412 (can refer to Production of exocellular polysacch...

Embodiment 2

[0027] A novel fertilizer, which is prepared according to the following method:

[0028] 1) Dry the corn stalks in the sun, then crush them into corn stalk powder with a pulverizer, add them to the fermenter, then add soybean meal and 90°C water to the fermenter, stir evenly, and when the temperature drops to 30°C, add the mixed bacteria Under the stirring condition of 200 rpm, ferment for 40 hours to obtain a fermented liquid; wherein, the mass ratio of corn stalk powder, soybean meal, water and the mixed bacterial liquid is 5:2:20:1; the mixed bacterial liquid is composed of subtilis Bacillus liquid, Trichoderma harzianum liquid and nitrogen-fixing bacteria liquid were mixed according to the volume ratio of 1:1:1, and the concentrations of the three bacterial liquids were all 3×10 7 pieces / ml.

[0029] 2) Add vermiculite powder, peat, lignite powder, zeolite powder and water into the mixing tank according to the mass ratio of 3:2:1:1:10, stir at 500 rpm for 30 minutes, then...

Embodiment 3

[0032] The field test effect of the fertilizer that the embodiment of the present invention prepares:

[0033] Control 1: ordinary compound fertilizer: the content of nitrogen, phosphorus and potassium is 15:15:15;

[0034] Contrast 2: preparation method is the same as embodiment 1, but without fermented liquid;

[0035] Experimental group: the fertilizer prepared in Example 1.

[0036] Experimental method: selected from the Tanghe experimental field in Hedong District to plant winter wheat, the experimental fields treated with three groups of fertilizers have an average area of ​​one mu of land, and the amount of fertilizer used in each experimental field is 40kg. Wheat is harvested at the same time, and the yield per mu of wheat and the increase rate of wheat are measured; Simultaneous detection The number of grains per spike and thousand-grain weight of wheat. Experimental results: refer to Table 1.

[0037] group Grains per spike Thousand grain weight (g) ...

Abstract

The invention belongs to the technical field of agricultural fertilizers, and discloses a novel fertilizer. The fertilizer is prepared from microbial fermentation crop waste materials in combination with raw materials such as vermiculite powder, grass carbon, brown coal powder, zeolite powder, urea, monoammonium phosphate, potassium chloride and ammonium chloride. The invention also discloses a preparation method of the fertilizer. The fertilizer is prepared by effectively utilizing organic waste materials of crops in combination with the microbial fermentation technology, and is capable of improving the soil structure and controlling the loss of nutrients, and therefore, the fertilizer efficiency lasts for a long time.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to a novel fertilizer and a production process thereof. Background technique [0002] The fertilizer manufacturing industry has a history of more than 100 years. After entering the 21st century, with the development of modern agricultural production, people are looking forward to the emergence of multifunctional fertilizers in the field of fertilizers, which can improve the quality of soil, improve the yield of crops, and improve Production efficiency, reduce production or improve working conditions, protect the natural environment, so that people can eat agricultural products that are beneficial to health and pollution-free. [0003] Plant growth needs sixteen kinds of elements. In addition to N, P, and K, other small elements needed to activate plants must be added to the soil, otherwise it will cause an imbalance of plant nutrition in the soil and a...
