Microorganism bacterium composition, special biological organic fertilizer for tobacco containing the same, preparation and use method for the microorganism bacterium composition

Abstract

The present invention provides a microbe composition, tobacco-dedicated biological organic fertilizer containing the composition, its usage method. The microbe composition comprises aztobacter sp., pseudomonas fluorescence, Bacillus megaterium, bacillus mucilaginosus and bacteria capable of preventing and treating plant disease and insect pests. The microbe composition is mixed according to proportion with oligochitosan, lignite, grass charcoal, and bean cake and fermented to make bacteria powder fertilizer, and further added with potassium-enriching shale, bentonite and water-keeping agent to make bacteria granule fertilizer. The tobacco-dedicated biological organic fertilizer contains the above-mentioned bacteria powder fertilizer and granule fertilizer which contains natural mineral and good organic substance, C/N value being large, which fit the growth rule of tobacco plant and promote potassium fertilizer efficiency and possesses long-lasting potassium-supply capability and provides effective ingredient for tobacco.

Description

Technical field [0001] The invention relates to the technical field of bio-organic fertilizers, and more specifically to a combination of special bio-organic fertilizers for tobacco containing microbial flora, prevention and control of tobacco plant diseases and insect pests and beneficial nutrients required for the growth of tobacco plants, and preparation and use methods. Background technique [0002] Tobacco contains more than 40 elements, some of which are essential elements. Among the essential elements, C, H, and O come from air and water, and the rest come from the soil, so they become mineral nutrients. The essential elements are: large elements (N, P, K), medium elements (Ca, Mg, S), and trace elements (Cl, Cu, B, Mo, Mn, Zn, Fe). [0003] At present, as the main measure to improve tobacco quality, increase output value and protect tobacco plants from various pests and diseases, a variety of chemical pesticide control methods are used. Chemical control is still one of th...

Problems solved by technology

Since biological control is based on prevention and long-term management, spraying biological pesticides when diseases appear cannot be effective immediately (the absorption of biological pesticides on the leaf surface of tobacco plants is very small), and the effect is not good.

[0010] (2) A large amount of harmful germs and diseased insect eggs remain in the organic matter in the existing bio-organic fertilizers. Although the sterilization treatment is carried out, they cannot be completely removed, causing the soil environment of the tobacco plants to be artificially polluted.

Tobacco planting soil in my country has strong potassium fixation capacity. Although the currently used bio-organic fertilizers have a certain potassium-dissolving effect, due to poor soil water retention and the impact of soil dry-wet alternation, the supply capacity of potassium in the middle and late stages is insufficient.

Therefore, after bio-organic fertilizer is applied, a large amount of chemical potassium fertilizer needs to be topdressed. At present, the potassium fertilizers used in tobacco planting are mainly potassium sulfate and potassium nitrate, which are quick-acting fertilizers. The water leaching is wasteful and pollutes the soil. The residue increases, and the internal quality is manifested as insufficient aroma, bad taste, high tar content, and does not meet the needs of the development of the safe cigarette industry.
