Method for preparing organic fertilizer through tobacco extracting solution

Abstract

The invention discloses a method for preparing organic fertilizer through tobacco solution. By adopting the method, the tobacco extracting solution can be subjected to waste recovery and prepared into organic fertilizer, and the method for processing the extracting solution by degrading through a large number of devices at present is replaced. According to the method, a microbial agent is added to the tobacco extracting solution for fermenting, and the prepared organic fertilizer includes a plurality of organic acid, peptides and rich nutrient elements such as nitrogen, phosphorus and potassium, so that the organic fertilizer can be used for providing comprehensive nutrition to crops, and the plant can be absorbed well; and furthermore, the organic matters in the soil can be increased and updated, so that the microbial proliferation can be promoted, and the physicochemical property and biological activity of the oil can be improved. The tobacco extracting solution includes nicotine which can be used for disinfesting, and the nicotine is remained in the finally obtained organic fertilizer during the processing of the method, so that the organic fertilizer has the effect of disinfesting.

Description

technical field [0001] The invention relates to the field of organic fertilizers, in particular to a method for manufacturing organic fertilizers using tobacco extracts. Background technique [0002] my country is the largest producer of tobacco leaves and cigarettes in the world, and a large amount of waste is produced in the tobacco production process, which mainly includes waste tobacco stems, waste tobacco leaves, tobacco residues, tobacco stalks, and tobacco dust. Tobacco stems and tobacco powder contain a large amount of N, P, K, trace elements and organic matter, which are very valuable agricultural resources. Rational use of this resource is an important task for the sustainable development of agriculture. [0003] Relevant data show that only the organic compounds in tobacco stems account for about 90%-95% (accounting for the total dry matter), and the mineral elements are 5%-10%; the nitrogen content is 0.5%-1.2%, and the phosphorus content is 0.1%- 0.25%, potassi...

AI Technical Summary

Problems solved by technology

The disadvantages of this method are: (1) The investment is too large and the operating cost is high

Generally, the investment of 10,000 tons / year paper-making tobacco flake sewage treatment station is more than 10 million yuan, and the operating cost is relatively high. The cost of sewage treatment per ton is more than 6 yuan. In the entire sewage load, the extract accounts for more than 50%

(2) Low degree of resource utilization

Biodegradation degrades organic matter, making it difficult to fully utilize and recycle resources

(3) Operation and management are difficult

Sewage treatment requires a balanced and stable sewage load, and the unbalanced discharge of the extract often has an impact on sewage treatment, resulting in unsatisfactory treatment effects
