Problems solved by technology

This method does not need to use equipment such as blowers. The method is simple and operable, and is easy to be mastered by the majority of farmers. It is very suitable for small farms to process pig manure on the spot (without transportation), thereby avoiding the existing "pig manure is not easy The problem of pig manure that cannot be effectively used and pollutes the environment caused by the difficulty of transportation and treatment

Embodiment 1

[0026] (1) Pretreatment: Dry the fresh pig manure for 2 days to reduce its moisture content to 53.01%. Use a pulverizer to crush the dried vegetable stalks until the length is less than 15mm. Use an atomizing spray tool to evenly spray water on the crushed straws. After spraying, the water content is 54.52%, and set aside.

[0027] (2) Mixing: mix the treated pig manure with vegetable straw, the proportion is 52.84kg dry weight of pig manure, 25.92kg dry weight of vegetable straw, the dry weight ratio of the two is 2:1, and then add water Evenly adjust the water content of the mixed material to 60.1%.

[0028] (3) Heating stage: the mixture obtained in step (2) is transported to a ventilated and rain-sheltered place and piled up together. The length of the heap is 1.5 meters, the width is 1.2m, and the height is 1.5m for aerobic fermentation. At the same time, one hole is punched on the top surface of the pile near the four sides, and one hole is punched in the center. The fi...

Embodiment 2

[0032] (1) Pretreatment: Dry the fresh pig manure for 2 days to reduce its moisture content to 65.52%. The dried vegetable stalks are pretreated with a mechanical pulverization method. The mechanical pulverization method uses a pulverizer to pulverize the dried vegetable stalks. Crushed stalks to make their water content 54.19%, treated for later use

[0033] (2) Mixing: mix the treated pig manure with vegetable straw, the ratio is 40.32kg dry weight of pig manure, 20.16kg dry weight of vegetable straw, the dry weight ratio of the two is 2:1, and then add water The water content is uniformly adjusted so that the water content of the mixed material is 61.72%.

[0034] (3) Heating stage: the mixture obtained in step (2) is transported to a ventilated and rain-sheltered place and piled up together. The length of the heap body is 1.6m, the width is 1.1m, and the height is 1.4m for aerobic fermentation. At the same time, a hole is drilled on the surface of the pile near the four ...

Abstract

The invention discloses a method for producing an organic fertilizer by pig manure and vegetable stalks. According to the method, the pig manure and the vegetable stalks are directly mixed for compostfermentation after simple treatment; the dry weight ratio of the pig manure and the vegetable stalks and the water content of the mixed materials are strictly controlled; the artificial hole formingnatural ventilation mode is used for ventilation so as to improve the compost success ratio. The artificial hole forming natural ventilation is used for replacing blast blower equipment; the additionof fermentation bacterial agents, inorganic fertilizers and other lignocellulose substances is not needed; the vegetable stalks are used as pig manure compost conditioning agents; the pig manure compost fermentation period is shortened; the product thoroughly decomposed degree and the nutrient content in the compost product are improved. The whole method is simple; the implementation is easy; theoperability is high; the method can be easily mastered by wide farmers; the method is very suitable for being popularized and applied to small farms.

Description

technical field [0001] The invention belongs to the technical field of composting, and in particular relates to a method for producing organic fertilizer by using pig manure and vegetable stalks. Background technique [0002] With the continuous improvement of my country's economic and social level, people's demand for pork products is increasing year by year, and the scale of pig farming is expanding, while the damage to the environment is also increasing. According to statistics, my country produces 3.8 billion tons of livestock and poultry manure every year. From the perspective of utilization, pig manure is the product of preliminary digestion, rich in organic matter, high content of nitrogen, phosphorus, potassium and trace elements, after fermentation, it can be used as organic fertilizer, suitable for various soils and crops, with good It is the fertilizer with the most comprehensive nutrition. However, due to the characteristics of high water content, difficult tra...
