Embodiment 1

[0050] Embodiment 1 A kind of compound bacterial fertilizer

[0051] This embodiment provides a kind of composite bacterial fertilizer, which is prepared from the following components by weight:

[0052] Carrier 99.2 parts;

[0053] Composite bacterial agent 0.8 parts.

[0054] Described composite bacterial agent is made up of following bacterial strain:

[0055] Bacillus subtilis 800 million cfu / g;

[0056] Beauveria bassiana 400 million cfu / g.

[0057] The carrier is made by mixing cotton stalks, sheep dung, rapeseed meal and cow dung in a weight ratio of 8:4:1:5, and fermenting through microbial composting. The microbial starter required for the composting fermentation contains Streptomyces californica hygroscopicus, Paecilomyces lilacinus, and Bacillus subtilis, and the ratio of the number of viable bacteria among the three is 1-2:0.5-1.5:5-8, wherein the total bacteria The number is 20 billion / g, and the addition amount is 4.0kg / ton dry material.

Embodiment 2

[0058] Embodiment 2 A kind of compound bacterial fertilizer

[0059] This embodiment provides a kind of composite bacterial fertilizer, which is prepared from the following components by weight:

[0060] Carrier 99.5 parts;

[0061] Composite bacterial agent 0.5 parts.

[0062] Described composite bacterial agent is made up of following bacterial strain:

[0063] Bacillus subtilis 1 billion cfu / g;

[0064] Beauveria bassiana 400 million cfu / g.

[0065] The carrier is the same as in Example 1.

Embodiment 3

[0066] Embodiment 3 A kind of compound bacterial fertilizer

[0067] This embodiment provides a kind of composite bacterial fertilizer, which is prepared from the following components by weight:

[0068] Carrier 99.7 copies;

[0069] Composite bacterial agent 0.3 parts.

[0070] Described composite bacterial agent is made up of following bacterial strain:

[0071] Bacillus subtilis 600 million cfu / g;

[0072] Beauveria bassiana 200 million cfu / g.

[0073] The carrier is the same as in Example 1.

Abstract

The invention relates to a compound bacterial fertilizer as well as a preparation method and application thereof. The compound bacterial fertilizer comprises the following components in parts by weight: 0.3-1.5 parts of compound bacterial agent and 98.5-99.7 parts of carrier, wherein the compound bacterial agent contains 0.3-1.5 billion cfu/g of bacillus subtilis and 0.15-0.5 billion cfu/g of beauveria bassiana; the collection number of the bacillus subtilis is ACCC10118; the collection number of the beauveria bassiana is ACCC30724; and the carrier is powder prepared from cotton straw, sheep manure, rapeseed meal and cow dung through compositing fermentation treatment of a microbial fermenting agent. In the invention, the beauveria bassiana and bacillus subtilis are mixed, and in specific proportion condition of the two, the maximum synergistic effect can be realized, and the agricultural and forest pests are effectively controlled; and moreover, due to relatively small quantity of strains, the bacterial fertilizer cost can be further reduced, the preparation technology is simplified, and agricultural control popularization is facilitated.

Description

technical field [0001] The invention relates to a compound bacterial fertilizer prepared by using cotton stalks, a preparation method and application thereof, and belongs to the field of organic fertilizers. Background technique [0002] Beauveria bassiana (B. bassiana) belongs to Deuteromycotina, Hyphomycetes, Moniliales, Moniliaceae, Beauveria in classification (Beauveria). Beauveria bassiana (B. bassiana) is one of the insecticidal fungi widely used in the biological control of pests at home and abroad, and is considered to be the most promising entomopathogenic fungus. Researchers at home and abroad have used Beauveria bassiana to control agricultural and forestry pests such as corn borer, pine caterpillar, small sugarcane borer, blind toon, grain weevil, citrus red spider and aphids. Because Beauveria bassiana can effectively control the population of insects without harming other natural enemy insects and beneficial organisms, it fully meets the purpose of integrated...
