Problems solved by technology

Green mud is one of the three wastes in the sugarcane sugar industry; green mud accounts for 2 to 3% of the amount of cane squeezed. my country's sugarcane output is about 6,700 tons, and about 2 million tons of green mud are produced; green mud contains a lot of nutrients Substances, including protein: 15-17%, fat: 10-15%, sugar: 10%, etc., nitrogen: 6-7%, phosphorus: 1-2%, potassium: 1-2% and other trace elements, It is an important organic fertilizer source and a good raw material for organic fertilizer production; besides the above-mentioned nutrients, green mud also contains 60% water, so it cannot be directly used, and it needs to be used after fermentation and storage. Conventional fermentation and storage is carried out under natural conditions, so beneficial microorganisms cannot occupy an absolute advantage in the fermentation process. Many miscellaneous bacteria will breed, a large number of bacteria will grow, and toxic and harmful substances will be produced to cause secondary pollution to the environment.

Embodiment 1

[0027] First spread the green mud on the leveled land, with a thickness of 60cm, spray the microbial agent based on enzyme bacteria on the green mud, ferment and dry it; when the water content is 33%, detect its nutrient content , calculated as dry matter: nitrogen 6-7%, phosphorus 1-2%, potassium 1-2%, protein 1517%, fat 10-15%, sugar 8-10%.

[0028] By 55% green mud after fermentation, 39.9% of chemical fertilizers, 5% of trace elements, 0.1% ratio of microbial bacterial agent, wherein in the bacterial agent, enzyme bacteria: nitrogen-fixing bacteria: phosphorus-solubilizing and potassium-decomposing bacteria weight ratio is 5 : 3.0: 6.5; put the above-mentioned raw materials together into a mixer and mix evenly; make powdery green clay bio-organic-inorganic compound fertilizer.

Embodiment 2

[0030] Spread the green mud on the leveled land with a thickness of 90cm, spray the microbial agent based on enzyme bacteria on the green mud, ferment and dry. When the water content is 40%, detect its nutrient content, calculated by dry matter: 5-6% nitrogen, 0.6-1.5% phosphorus, 0.6-1.5% potassium, 12-15% protein, and 8-10% fat 12%, containing 5-6.5% sugar.

[0031] According to the ratio of 65% of fermented green mud, 33.5% of chemical fertilizer, and 1% of trace elements, the above raw materials are put into a mixer and mixed evenly. Through extrusion granulation and drying, the aqueous solution of microbial flora is sprayed on the granular fertilizer by spraying method at the discharge port. The amount of microbial bacterial agent is 0.5% of the total weight of the fertilizer. The weight ratio of bacteria: nitrogen-fixing bacteria: phosphorous and potassium-solubilizing bacteria is 7:1.5:4.5; the granular green mud bio-organic-inorganic compound fertilizer is made.

Abstract

The present invention relates to fertilizer, and is especially one kind of biological organic composite green mud fertilizer and its preparation process. The green mud fertilizer consists of microbial fermented green mud 40-75 wt%, inorganic azophoska 20-55 wt%, trace elements 1-5 wt% and microbial preparation 0.1-0.5 wt%. The present invention has the following advantages: low cost, balanced nutrients, long fertilizing effect, obvious yield increasing effect, wide application range, capacity of raising organic matter content improvement of soil physical and chemical characters, raising water and fertilizer maintaining ability of soil, raising the quality of agricultural product and reducing pollution.

Description

technical field [0001] The invention relates to a bio-organic fertilizer, in particular to a green clay bio-organic compound fertilizer and a preparation method thereof. Background technique [0002] Sugarcane is the main sugar crop in my country, with an annual planting area of ​​1,189,000 hectares and a production of 66.876 million tons of sugarcane, which is mainly used in the sugar industry. In the sugarcane sugar industry, many by-products and wastes are produced. The by-product bagasse is mainly used to process construction and furniture materials; molasses is mostly used to produce alcohol; green mud is the waste of the sugar industry that is discarded. Green mud is one of the three wastes in the sugarcane sugar industry; green mud accounts for 2 to 3% of the amount of cane squeezed. my country's sugarcane output is about 6,700 tons, and about 2 million tons of green mud are produced; green mud contains a lot of nutrients Substances, including protein: 15-17%, fat: 10...
