According to the planning of the relevant state departments, by 2015, the area of ​​Jatropha curcas cultivation in my country will reach 8×10 6 hm 2 , Jatropha curcas will leave a large amount of oil residue after oil extraction, and tens of millions of tons of Jatropha curcas cake waste will be produced. This situation has brought great pressure to the local environment. The centralized treatment and recycling of jatropha oil meal has brought possibility

Embodiment 1

[0021] Production of 2 kg of product: take 2 kg of fresh jatropha oil meal crushed through a 100-mesh screen at 0.1MPa, 120°C, and sterilize for 30 minutes, then take 0.6 kg of Trichoderma viride seed liquid and mix evenly to control the initial content of The water content is 70%, the pH=7.0, the atmospheric pressure is turned over once every 24 hours, maintained at 30-32°C, and the aerobic fermentation is continued for 120 hours. After drying, it is measured and packaged to obtain the required microbial organic fertilizer. The effective components are: Organic matter ≥ 40% (including amino acid ≥ 14%), N+P 2 o 5 +K 2 O≥13.33%, the total number of effective viable bacteria≥1.43×10 8 cfu / g, Fe, Zn, Mo trace element content 1.5%, As, Hg heavy metal content 0; roundworm egg mortality rate is higher than 95%, the number of fecal coliform bacteria is lower than 100 / g, pH is 7.16, Moisture content 30%.

Embodiment 2

[0023] Production of 10 kg of product: Take 10 kg of fresh jatropha oil meal crushed through a 200-mesh sieve at 0.1MPa, 120°C, sterilize for 30 minutes, then take 1 kg of Trichoderma viride seed liquid and mix evenly to control the initial content The water volume is 75%, the pH=7.0, the normal pressure is turned over every 24 hours, maintained at 30-32°C, and the aerobic fermentation is continued for 6 days. After air-drying, it is measured and packaged to obtain a microbial organic fertilizer. Requirements for inventing microbial organic fertilizers.

Embodiment 3

[0025] Production of 20 kg of product: take 20 kg of fresh jatropha oil meal that has been crushed through a 400-mesh sieve at 0,1MPa, 120°C, and sterilize for 30 minutes, then take 5 kg of Trichoderma viride seed liquid and mix evenly to control the initial Moisture content is 75%, pH=7.0, turned over every 24 hours under normal pressure, maintained at 30-32°C, continued aerobic fermentation for 7 days, measured and packaged after drying, and obtained microbial organic fertilizer, in which the indicators of each component meet the requirements of The requirements of the microbial organic fertilizer of the present invention.

[0026] The microbial organic fertilizer of the present invention is tried out in vegetable planting such as lettuce, fertilizer 0.6 tons / ha (or 40kg / mu), topdressing mode is applied, and the use time is carried out when the lettuce is strong. The depth of fertilization is 15cm, and the soil should be turned or covered after fertilization. When fertilizi...

Abstract

The invention discloses a microbial organic fertilizer and a preparation method thereof. The method comprises the following steps: inoculating a Trichoderma viride fungus seed solution into jatropha oil meal in preparation; controlling the initial moisture content at 70-80%; evenly stirring, and setting the temperature at 20-40 DEG C; and adopting still fermentation, and turning over once at an interval of 24 hours under the condition of pH=7.0 at constant pressure to ensure an aerobic condition, and controlling the fermentation time at 4-7 days, so as to obtain the microbial organic fertilizer.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a microbial organic fertilizer and a preparation method thereof. Background technique [0002] Jatropha curcas is a large-scale oil crop planted in tropical and subtropical regions. It is widely planted in Yunnan, Guizhou, Guangxi, Hainan, and Southeast Asia. According to the planning of the relevant state departments, by 2015, the area of ​​Jatropha curcas cultivation in my country will reach 8×10 6 hm 2 , Jatropha curcas will leave a large amount of oil residue after oil extraction, and tens of millions of tons of Jatropha curcas cake waste will be produced. This situation has brought great pressure to the local environment. The centralized treatment and recycling of jatropha oil meal has brought possibility. [0003] The bio-organic fertilizer produced by microbial technology is a new type of fertilizer that has developed rapidly in recent years. It is a biological product that c...
