Embodiment 1

[0027] Example 1: The preparation method of organic and inorganic drought-resistant compound fertilizer comprises the following steps:

[0028] (1) Organic fertilizer equipment: crush the larger individual raw materials in the organic fertilizer raw materials, such as straw, deciduous poultry and livestock manure, etc., into small pieces of 2-3 cm;

[0029] (2) Composting and fermenting organic fertilizer: dry the straw or fallen leaves, kitchen waste, etc. in the organic raw materials, and then crush them into the mixer, and add any proportion of poultry manure, monosodium glutamate residue, humic acid, and sludge at the same time , peat, etc., inoculated with high-efficiency microbial fermentation strains, added water and stirred evenly, to a humidity of 50% to 60%; stacked into a flat-top fermentation stack with a width of 1.5 to 3 meters and a height of 1.0 to 1.5 meters, and covered with black plastic Thin film, carry out anaerobic composting; remove the film after 3 to ...

Embodiment 2

[0033] Example 2: Take 8 parts of dried orange stalks, chop them, mix them with 5 parts of dried monosodium glutamate residue, 12 parts of crushed chicken manure and duck manure, 5 parts of humic acid, 5 parts of peat, and 4 parts of sludge, and put them into a mixer. Inoculate high-efficiency microbial fermentation strains, add water and stir evenly until the humidity is 60% and the pH value is 7.0. The pile is made into a flat-top fermentation pile with a width of 2 meters and a height of 1.5 meters, and is covered with a black plastic film for anaerobic stacking. After 3 to 5 days, remove the film, turn the pile with a throwing machine, aerobically stack until the temperature rises to 70°C, turn the pile again, and replenish water; repeat 3 to 5 times until the material is decomposed and the volume is reduced to the raw material 2 / 3 of the volume; natural volatilization and drying, when the moisture content of the organic fertilizer is below 25%, the organic fertilizer is...

Embodiment 3

[0036] Take 7 parts of dried rice orange stalks, 3 parts of kitchen waste, chop and mix with 5 parts of dried monosodium glutamate residue, 15 parts of crushed cow dung, 4 parts of humic acid, and 5 parts of peat, put them into a blender, and inoculate High-efficiency microbial fermentation strains, add water and stir evenly, until the humidity is 60%, and the pH value is 7.0. Pile into a flat-top fermentation pile with a width of 2.2 meters and a height of 1.8 meters, and cover the outside with a black plastic film for anaerobic stacking. After 3 to 5 days, remove the film, turn the pile with a turning machine, aerobically stack until the temperature rises to 70°C, turn the pile again, and replenish water; repeat 3 to 5 times until the material is decomposed and the volume is reduced to the raw material 2 / 3 of the volume; natural volatilization and drying, when the moisture content of the organic fertilizer is below 25%, the organic fertilizer is made.

Abstract

The invention provides an organic/inorganic drought resisting compound fertilizer and a preparation method thereof. The preparation method comprises the following special steps of: at first, carrying out harmless treatment on raw materials of an organic fertilizer, such as livestock excrement, crop straws, kitchen garbage, fallen leaves, turf and peat, humic acid and the like, so as to obtain the organic fertilizer; then adding a macromolecule moisture retention material and an inorganic fertilizer at a certain ratio and uniformly stirring; and finally obtaining the organic/inorganic drought resisting compound fertilizer by extruding granulation. The organic/inorganic drought resisting compound fertilizer disclosed by the invention has functions of drought resistance and moisture retention, nutrient slow release and soil fertilization, so that the effects of increasing production and income of the crops are achieved. Furthermore, the organic/inorganic drought resisting compound fertilizer can effectively solve the environment pollution caused by the livestock excrement, straw burning and domestic garbage.

Description

technical field [0001] The invention relates to a compound fertilizer, in particular to an organic-inorganic drought-resistant compound fertilizer and a preparation method thereof. Background technique [0002] my country is a traditional large agricultural production country with a large population. In the process of agricultural production and life, a large amount of organic waste will be generated, such as livestock and poultry manure, crop straw and kitchen waste. Relevant data show that the annual production of livestock and poultry manure in the country is about 1.73 billion tons, of which the annual production of nitrogen is about 15.97 million tons, and the annual production of phosphorus is about 3.63 million tons. The loss rate of livestock and poultry manure entering water bodies is as high as 25%-30% % . The loss of N and P caused by poultry manure is even greater than the loss of chemical fertilizers. my country can produce more than 700 million tons of straw ...
