preparation example Construction

[0052] The invention provides a preparation method of the special organic fertilizer for corn, comprising the following steps:

[0053] A. Mix the modified peanut shell biochar, decomposed bacteria residue, fish bone meal, dehydrated enteromorpha, 2-2.5 parts of yeast compost starter and 0.1-0.25 parts of cellulase, and adjust the water content to 60%-70% Finally, set up piles and ferment at 25-40°C for 12-18 days, and turn the piles once every 2-4 days to obtain the first fermented product;

[0054] B. When the temperature of the first fermented product is lowered to below 40°C, mix it with wood vinegar, glucose, a remaining amount of yeast compost starter and a remaining amount of cellulase, and adjust the water content to 40% to 50%. 20~40℃ for the second compost fermentation to obtain biochar-based organic fertilizer.

Embodiment 1

[0066] A preparation method of special organic fertilizer for corn, comprising the following steps:

[0067] Raw material preparation:

[0068] A. Bacterial residue decomposing: Inoculate the bacterial residue with Bacillus megaterium PP84 for aerobic fermentation and decomposing. Adjust the water content of the bacteria residue to 60% to 70%, and the concentration of the bacteria solution is about 2×10 8 The spore suspension of Bacillus megaterium PP84 with 1 spore / mL was added to the spores according to the inoculation amount of 1.5%, fully mixed and stirred, and naturally fermented for 12 days. The fungus residue is naturally air-dried to normal temperature, dried, placed in a pulverizer to pulverize, and passed through a 20-mesh sieve to obtain a decomposed mushroom residue.

Abstract

The invention provides an organic fertilizer special for corn and a preparation method and application thereof, and belongs to the technical field of fertilizers. The organic fertilizer special for the corn is prepared from, by weight, 30-40 parts of modified peanut shell biochar, 30-45 parts of bacterial residues, 15-25 parts of dehydrated enteromorpha prolifera, 15-20 parts of fish bone meal, 6-8 parts of wood vinegar, 4-6 parts of glucose, 3-5 parts of a yeast composting starter and 0.2-0.35 part of cellulase through fermentation. By applying the biochar-based organic fertilizer special forthe corn to corn planting, the effects of land nourishment and yield increase are achieved, and the organic fertilizer is an optimal fertilizer source for corn organic cultivation; the needed raw materials are mostly organic waste and are easy to obtain, the cost is low, the technology is advanced, and the fertilizer can be produced on a large scale.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a special organic fertilizer for corn and its preparation method and application. Background technique [0002] Corn is an important planting crop in eastern Shandong. In order to increase production and control the planting density reasonably, chemical fertilizers must be used scientifically. At present, the phenomenon of unreasonable and excessive use of chemical fertilizers is particularly common. Excessive and unreasonable application of chemical fertilizers not only wastes valuable agricultural resources, but also leads to a rapid decline in soil fertility, directly affecting crop yield and quality. In addition, after a large amount of chemical fertilizer is applied, a large part of the chemical fertilizer will easily flow into the surrounding water body along with the farmland drainage path, causing agricultural non-point source pollution.
