Description

Carbon-containing organic fertilizer suitable for corn and production process thereof

Technical Field

The invention relates to the technical field of production and processing of carbon-containing organic fertilizers, in particular to a carbon-containing organic fertilizer suitable for corn and a production process thereof.

Background

The annual output of the quick-acting fertilizer in China is ranked first in the world, the annual usage amount of the quick-acting fertilizer reaches more than 5100 ten thousand tons (pure amount), accounts for more than 30% of the total consumption amount in the world, and is the sum of America and India. The amount of the homogenized fertilizer per mu is 21.2 kilograms which is far higher than the world average level of 8 kilograms in China, 3 times that in the United states and 2.5 times that in India and European Union, and China becomes the largest chemical fertilizer consuming country in the world. Excessive fertilizer not only increases the agricultural planting cost, but also causes soil hardening and fertility reduction, thereby entering into the vicious circle of increasing the fertilizer.

Biochar refers to a carbon-rich solid material formed by biomass at a certain temperature. In the aspect of agriculture, the biomass charcoal has the functions of soil improvement and soil carbon fixation, and is a good soil improvement agent and fertilizer slow-release material. The biomass used as the solid waste in agricultural production is converted into biochar through a low-temperature carbonization process to become the main component of the carbon-based fertilizer, and the biochar is applied to the soil, so that the problems of soil impoverishment, soil pollution, soil degradation, soil hardening, slow release of fertilizer efficiency, water retention and carbon sequestration and ground temperature increase can be solved.

Corn plays an important role in national economy as the second major food crop in China. In recent years, the "mission" of corn, which is the crop with the widest growing area in the world, is shifting from ordinary food consumption and feed consumption to industrial processing raw materials.

Although the corn planting area and the corn yield are steadily increased in China, the production cost is also continuously increased. Especially, the input of chemical fertilizers is increased rapidly, and the competitiveness of corn products in China in domestic and foreign markets is severely limited. In the corn planting process of China, farmers pursue high yield on one side and apply chemical fertilizers for a long time in a blindly excessive way, which has caused the problems of no yield increase of the fertilizer increase, weak lodging of corn plants, low nutrient utilization efficiency, poor grain quality, soil acidification, nutrient loss and water eutrophication. These problems in turn largely inhibit the improvement of corn yield. Therefore, the development of a multi-benefit functionalized ecological fertilizer product aiming at the soil with reduced productivity caused by the application of a large amount of fertilizers is a problem to be solved urgently in the corn planting industry in China at present.

Disclosure of Invention

The carbon-based fertilizer is an ecological environment-friendly fertilizer prepared by taking biochar which is a product obtained by carbonizing wheat straws, corn straws, cotton straws, soybean stalks, peanut shells and branches as a matrix and adding organic matters and inorganic matters according to the characteristics of land in different areas and the characteristics of nutrients and elements required by the growth of different crops.

According to actual production experience, in the production process of the carbon-containing organic fertilizer, the adsorption effect of the biochar is utilized, the granular structure of soil is improved, carbon elements required by plants are supplemented, the utilization rate of the fertilizer is improved, the growth environment of plants is effectively improved, and the stress resistance of the plants is improved.

The invention develops the carbon-based organic fertilizer suitable for planting corn by utilizing the soil improvement effect of the biochar and combining factors of the requirements on organic matters and nutrient elements in the corn growth process.

In order to achieve the above purpose, the technical scheme adopted by the invention is as follows:

a. selection of raw materials: selecting biochar as a main material of the carbon-containing organic fertilizer, and controlling the water content of the biochar to be below 5%;

b. the proportion of the raw materials is as follows: a carbon-containing organic fertilizer suitable for corn is composed of the following raw materials in parts by weight: 20-50 parts of humic acid, 20-40 parts of plant ash, 20-35 parts of biochar and 10-40 parts of thoroughly decomposed edible fungus stick waste;

c. selecting a preparation site: a dry and totally-enclosed workshop is selected as a preparation site;

d. preparing a mixture: firstly, all the raw materials are crushed into 80 meshes, mixed evenly according to the proportion and then granulated.

The invention has the beneficial effects that:

1. the invention solves the demand of carbon element in the corn planting process, enhances the fertility efficiency of the growing environment of corn plants, and innovates the production formula of the special carbon-containing organic fertilizer for corn;

2. the invention provides the combination of the biochar and the traditional organic fertilizer production process, and provides a feasible formula and process for solving the problem of the special carbon-based fertilizer for the corn;

3. the invention utilizes the adsorption effect of the active carbon to improve the granular structure of the soil, supplement carbon elements required by plants and improve the utilization rate of the fertilizer.
