Embodiment 1

[0052] Embodiment 1 Composite microbial bacterial agent, its preparation and application

[0053] 1.1 Formula of compound microbial agent

[0054] The active ingredient of the complex microbial agent is: Bacillus licheniformis 1×10 9 cfu / g, Bacillus Laterosporu (Brevibacillus laterosporu) 0.5×10 9 cfu / g, Bacillus pumilus 0.5×10 9 cfu / g, Bacillus magaterium 2×10 9 cfu / g, Silicate bacteria (Silicate bacteria) 1×10 9 cfu / g, etc., so that the total number of effective viable bacteria is ≥5×10 9 cfu / g. Among them, Bacillus licheniformis is ACCC10618 of China Agricultural Microorganism Culture Collection Management Center; Bacillus pumilus is China Agricultural Microbiology Culture Collection Management Center ACCC10121; Culture Collection Management Center ACCC03031; silicate bacteria is China Agricultural Microbiology Culture Collection Management Center ACCC02983.

Embodiment 2

[0087]4. It can be seen from the above table 1 that the application of compound microbial agent can promote the growth and development of tobacco plants, and its effect is significantly better than that of common fertilizers. Embodiment 2 Fertilizer for tobacco planting, its preparation and application

[0088] 1.1 Composition of fertilizers for tobacco planting (by weight)

[0089] 1 part of compound microbial agent;

[0090] 5 parts of activator;

[0091] 5 parts of binder;

[0092] 89 parts of nitrogen, phosphorus and potassium fertilizers.

[0093] The active ingredient of the compound microbial agent is: Bacillus licheniformis (Bacillus licheniformis) 1×10 9 cfu / g, Bacillus Laterosporu (Brevibacillus laterosporu) 0.5×10 9 cfu / g, Bacillus pumilus 0.5×10 9 cfu / g, Bacillus magaterium 2×10 9 cfu / g, Silicate bacteria (Silicate bacteria) 1×10 9 cfu / g, etc., so that the total number of effective viable bacteria is ≥5×10 9 cfu / g.

Embodiment 3

[0109] Embodiment 3 Application Effect Test of Fertilizer for Tobacco Planting of the present invention

[0110] 1.1 Materials and methods

[0111] 1.1.1 The name and source of the tested bacterial fertilizer

[0112] The tobacco planting fertilizer prepared in Example 2, anti-fusarium verticillium wilt bacteria fertilizer (purchased from Laohekou Biological Fertilizer Company of Hubei Province).

[0113] 1.1.2 Test treatment

[0114] The experiment adopts random block design, and the experiment involves 2 kinds of biological fertilizers and 1 control. According to the conventional fertilization method, each treatment is repeated 3 times, in a single row area, and 30 tobacco plants are planted in each plot. Tobacco planting fertilizer of the present invention and Verticillium dahliae resistant bacterium fertilizer of the present invention are used as bottom fertilizer 30kg per mu, and 15kg per mu is used as hole fertilizer when transplanting tobacco seedlings, and topdressin...

Abstract

The invention provides a fertilizer for cultivation of tobacco. The fertilizer consists of the components by weight as follows: 0.5-1.5 parts of a composite microbial agent, 3-7 parts of an activating agent, 3-7 parts of binder, and 86-92 parts of nitrogen, phosphorus and potassium fertilizer. The effective components of the composite microbial agent are Bacillus licheniformis, Bacillus pumilus, Brevibacillus laterosporus, Bacillus megatherium and Silicate bacteria. The invention further provides a preparation method and an application of the fertilizer. The product provided by the invention can remarkably improve crumb-structure of soil for cultivation of tobacco, and microflora distribution and micro-environment of the soil. A plenty of derivatives are generated, thereby chelating or blocking damage of heavy metals, and absorption and assimilation of tobacco to nutrient elements are improved, the drought resisting and disease resisting abilities of tobacco are enhanced, damage of diseases and insects caused by continuous cropping of tobacco in successive years are effectively prevented, and in particular, tobacco mosaic virus and brown spot disease are specially prevented and treated. According to the invention, the raw materials are low in cost and easy to obtain and the preparation and using methods are simple and easy to operate.

Description

technical field [0001] The invention belongs to the field of microbial fertilizers, and in particular relates to a tobacco planting fertilizer, its preparation method and application. Background technique [0002] The existing biological fertilizers in my country are all based on organic matter, and then mixed with bacterial agents and inorganic fertilizers. The application of biological fertilizers in agriculture has been gradually recognized by people. In order to broadly improve the status quo of this traditional bio-fertilizer, researchers are committed to developing new bio-fertilizer products that can not only provide crop nutrition, but also improve soil; Eliminates pollutants in the soil and at the same time rehabilitates the soil. [0003] Like chemical fertilizers and organic fertilizers, biological fertilizers are important fertilizer sources in tobacco production. In recent years, due to the large amount of unreasonable application of chemical fertilizers and ...
