Problems solved by technology

[0004] The traditional aerobic composting technology of tobacco stalks mainly has two outstanding problems: one is that the main fermentation temperature is generally lower than 70°C, which cannot eliminate pathogenic microorganisms in tobacco stalks, which increases the risk of planting diseases and insect pests in tobacco planting in the next year (Zhang Nan, Liu Dongyang, Yang Xingming, et al. Screening of cellulose-decomposing high-temperature fungi and their degradation effects on tobacco stems [J]. Journal of Environmental Science, 2010, 30 (3): 549-555.); the second is to make fertilizer after crushing tobacco stems The fermentation cycle is relatively long, and the biodegradation is very slow, usually for several months, or even longer
This is mainly due to the fact that the dense and complex spatial structure of tobacco stalks restricts its biodegradation and is also a bottleneck factor hindering its resource utilization.

Embodiment 1

[0025] First, the collected tobacco stalks were crushed into 7cm pieces, and then put into the gas explosion chamber of the steam explosion equipment, and the steam explosion treatment was carried out under the conditions of steam pressure 2.5MPa and pressure holding time 120s. According to the ratio of 55% steam explosion straw, 30% chicken manure, and 12% conditioner (natural zeolite powder, diatomaceous earth, sawdust, rice husk, the mass ratio of the four substances is 1:2:1:2), the raw materials Mix well, stock C / N ratio is 30 / 1, moisture is 60%, pH6.5, inoculated with 3% microbial flora (Bacillus subtilis, Bacillus megaterium, Dispospora thermophiles and Aspergillus oryzae , the mass ratio of the four strains is 1:2:1:2), made into fermented strips with a height of 1.2m, mechanized turning and throwing to loosen materials and increase the amount of oxygen, and the temperature inside the fermentation is 40-70 ℃, after 15 days of fermentation, C / N ≤ 20, seed fermentation i...

Embodiment 2

[0027] First, the collected tobacco stalks were crushed into 5cm pieces, and then put into the gas explosion chamber of the steam explosion equipment, and the steam explosion treatment was carried out under the conditions of steam pressure 1.5MPa and pressure holding time 240s. According to the ratio of 60% of steam explosion straw, 27% of pig manure, and 10% of conditioner (natural zeolite), the raw materials are fully mixed and uniform, the stock C / N ratio is 28 / 1, the water content is 55%, and the pH is 5.5. 3% microbial flora (Bacillus subtilis, Bacillus megaterium, Sporosporium thermophila and Trichoderma reesei, the mass ratio of the four strains is 1:1:1:1), made into fermented strips , with a height of 1.0m, mechanized turning and throwing to loosen materials and increase the amount of oxygen. The temperature in the fermentation chamber is 40-75°C. After 12 days of fermentation, C / N≤20, seed fermentation index≥50%, and the fermentation is effective The number of viable...

Embodiment 3

[0029]Firstly, the collected tobacco stalks were crushed into small pieces of 10 cm, and then put into the gas explosion chamber of the steam explosion equipment, and the steam explosion treatment was carried out under the conditions of steam pressure 2.0 MPa and pressure holding time 120 s. According to the ratio of 30% of steam explosion straw, 50% of peat, and 15% of conditioner (sawdust, rice husk, the mass ratio of the two is 1:2), the raw materials are fully mixed and the stocking C / N ratio is 25 / 1, The water is 65%, pH5.5, inoculated with 5% of the microbial flora Bacillus subtilis, and made into a fermented bar with a height of 1.2m, which is mechanized to loosen the material and increase the amount of oxygen. The temperature in the fermented bar is 40-75℃, after 10 days of fermentation, C / N ≤ 20, seed fermentation index ≥ 50%, fermentation to reach effective viable count ≥ 0.2×10 8 When the index of each / g, pH6-8, organic matter content (dry basis) ≥ 30%, is the produ...

Abstract

The invention discloses a method for quickly producing a bio-organic fertilizer by using tobacco stalks and the bio-organic fertilizer. The raw materials for producing the bio-organic fertilizer in the method comprise the following substances in percentage by weight: 30 to 70 percent of tobacco stalks subjected to steam explosion treatment, 20 to 50 percent of mixed accessories, 5 to 15 percent of conditioning agent and 1 to 5 percent of microbial flora; and the bio-organic fertilizer is prepared through an aerobic composting process, wherein the stacking C / N ratio is adjusted to be 25 to 35 / 1, the water content is adjusted to be 50 to 65 percent, the pH is controlled to be 5.0 to 8.5, the strip stamping height is 1.0 to 1.5 m, and the tobacco stalks are crushed, screened and packaged after reaching a maturity index. The method has the characteristics of fast treatment, high efficiency and fast maturity, and has an important practical significance for fully using wasted tobacco stalk resources, improving the ecological environment of tobacco planting areas and reducing environmental pollution. The bio-organic fertilizer has high organic content, has the effects of improving the soil structure and improving the soil fertility, and can be widely used for planting economic crops of tobaccos, vegetables and the like.

Description

technical field [0001] The invention belongs to the technical field of agricultural resource utilization and bio-organic fertilizer production, and in particular relates to a method for rapidly producing bio-organic fertilizer by using tobacco stalks and the bio-organic fertilizer. Background technique [0002] Tobacco is the main economic crop in my country. According to statistics, in 2011, the planting area of ​​tobacco reached 21.18 million mu, the planting scale ranked first in the world, and the annual purchase volume of tobacco leaves reached 54.296 million tons. At the same time, about 3 million tons of agricultural waste—tobacco stalks—is produced every year. Due to the relatively high degree of lignification of tobacco stalks, it is not easy to rot, and it takes 2-3 years to naturally degrade and transform into humus even after crushing, which brings many technical difficulties for the resource utilization of tobacco stalks. Therefore, most of them are discarded o...
