Embodiment 1

[0034] The organic fertilizer for tobacco with antibacterial effect in this example is prepared by the following method.

[0035] The organic fertilizer for tobacco is obtained by fermenting oleaginous acid and humic acid as raw materials, that is, fermentation base, by adding microbial fermentation agents and harmful organism inhibitors. Humic acid can promote fermentation and increase the humic acid content in organic fertilizers. RT fermentation agent, containing Bacillus subtilis, Bacillus licheniformis, Aspergillus fumigatus, Aspergillus niger, cellulase (live), protease (live); the effective number of viable bacteria (cfu) is 2 to 3 billion / g, and the amount added is for fermentation 0.05 to 3% of the basis. In this example, the RT fermentation bacterial agent was purchased from the microbial bacterial agent produced by Hebi Runtian Biotechnology Co., Ltd., and the registration certificate number is Microbial Fertilizer (2018) Zhunzi (4306). The pest inhibitor is one o...

Embodiment 2

[0038] The present embodiment adopts the method of embodiment 1 to prepare the organic fertilizer for tobacco.

[0039] Mix 1000kg oily rot and 300kg humic acid, add 2.6kgRT fermentation agent and 2kg pest inhibitors, the pest inhibitors are Bacillus subtilis and Trichoderma after mixing 1:1, add 1100kg water and mix evenly, start fermentation.

[0040] Transfer the fermented material to a fermentation tank with a turner. After 2 days, the temperature of the material reached 60°C, and began to record the temperature change with the fermentation practice. Afterwards, it was turned and thrown once a day. After 20 days of fermentation, the temperature of the material dropped to 42° C., and the water content dropped to 35%. After the fermentation was completed, an organic fertilizer for tobacco with antibacterial effect was obtained.

[0041] The fermented organic fertilizer was detected by an amino acid automatic instrument, and the contents of different amino acids are shown in...

Abstract

The invention discloses an organic fertilizer for tobacco and a preparation method thereof. Oil cakes and humic acid are taken as raw materials, and a microbial fermentation inoculant and a pest inhibitor are added for fermentation treatment, thereby obtaining the organic fertilizer for tobacco. Trichoderma and bacillus subtilis are added into the organic fertilizer, so that organic matter decomposition can be promoted, tobacco plants can be prevented from being infected with black shank and bacterial wilt germs, the incidence rate of tobacco bacterial wilt and black shank is reduced, and the use of pesticides is reduced. The production period of the organic fertilizer is short, and the free amino acid content of the prepared organic fertilizer is increased from 0.18% to 5%. When the organic fertilizer is applied to tobacco planting, tobacco plants grow robustly, leaves develop well, and cured tobacco leaves are bright in color and luster, oily and moist and improved in aroma quality.

Description

technical field [0001] The invention belongs to the field of organic fertilizers, and relates to an organic fertilizer for tobacco and a preparation method of the organic fertilizer for tobacco. Background technique [0002] my country is a big tobacco planting country, and the tax revenue generated by the tobacco industry exceeds one trillion yuan every year. In the production of flue-cured tobacco, the quantity and scope of the application of oil-cured oil in the tobacco area is increasing continuously. The application of oil-cured oil can increase the agronomic traits of tobacco plants, such as stem height, stem girth, number of leaves, especially the largest leaf area, and finally increase in yield and quality, The economic benefits of flue-cured tobacco are increased on the average price and the ratio of upper medium tobacco. The application of oil can increase the activity of soil enzymes, accelerate the decomposition of soil organic nutrients, increase the nutrients ...
