Problems solved by technology

However, direct crushing and returning to the field without high-temperature fermentation can easily bring a large number of pathogenic bacteria into the soil; while indirect composting and returning to the field can also play a role in improving the soil, although it has undergone high-temperature fermentation to ensure that the soil is not brought into pathogenic microorganisms, but in addition to the above In addition to the function, there is no additional product output, and the added value is low

specific Embodiment approach 1

[0016] Specific embodiment one: a strain of Trichoderma viride in this embodiment is Trichoderma viride (Trichoderma viride) NECC30006, which is preserved in the General Microbiology Center of China Microbiological Culture Collection Management Committee, and the preservation address is No. 1, Beichen West Road, Chaoyang District, Beijing No. 3, the deposit date is July 15, 2015, and the deposit number is CGMCC No.11117.

[0017] In this embodiment, in the autumn of 2013, Trichoderma viride NECC30006 was isolated from the rhizosphere soil of Cirsiumsetosum in the field next to Baisheng Homeland in Harbin, Heilongjiang Province; the fungus grew rapidly, and the colony radius was 27mm in 48 hours at 28°C , the mycelial layer is thicker, conidia are produced later, dark green, and the colonies are concentric ring patterns. Microscopically, there are curved or hooked bottle stems. It was identified as Trichoderma viride through combination of morphological identification and mole...

specific Embodiment approach 2

[0019] Specific embodiment two: the application of a strain of Trichoderma viride in this embodiment refers to the application of Trichodermaviride (Trichodermaviride) NECC30006 in the production of Trichoderma bacterium fertilizer with corn stalks, wheat bran and ferrous sulfate as fermentation materials.

[0020] The beneficial effect of this implementation mode:

[0021] 1. The excellent characteristics of corn stalks are suitable for the preparation of Trichoderma fertilizer: compared with other raw materials, the main components of corn stalks are cellulose, sugar, inorganic salts and water, which are the nutrients needed for the growth of Trichoderma; corn stalks Compared with other raw materials, it has stronger air permeability, water absorption and water retention, and is more suitable for cultivating Trichoderma. The specific gravity of corn stalks is low, the relative surface area is larger after crushing, and the same quality can obtain greater spore production, wh...

specific Embodiment approach 3

[0025] Specific embodiment three: this embodiment differs from specific embodiment two in that the formula of the fermented material is: mix 76 parts of crushed corn stalks with 24 parts of wheat bran in parts by mass to obtain mixture A, and then add sulfurous acid Iron and water, wherein the addition of ferrous sulfate and water is the water that adds 0.3g ferrous sulfate and 3L in every kilogram of mixture A. Others are the same as in the second embodiment.

Abstract

The invention relates to trichoderma viride and application thereof. The trichoderma viride is trichoderma viride NECC30006, and is preserved in the China General Microbiological Culture collection center, the preservation address is No.3, #1 courtyard, Beichen West Road, Chaoyang District, Beijing City, the preservation date is July 15th, 2015, and the preservation number is CGMCC No.11117. Application of the trichoderma viride refers to application of the trichoderma viride NECC30006 in production of trichoderma sp fertilizer with corn straw, wheat bran and ferrous sulfate as fermentation materials.

Description

technical field [0001] The invention relates to a strain of Trichoderma viride and its application. Background technique [0002] As a biocontrol fungus against plant fungal diseases, Trichoderma has been widely used in agriculture and forestry due to its wide distribution, strong adaptability, short maturity period, fast growth, ability to improve soil, and broad-spectrum antibacterial and antibacterial properties. widely used in industry. Trichoderma viride in the genus Trichoderma has been widely studied and applied in terms of promoting plant growth and inhibiting the growth of pathogenic bacteria due to its good biocontrol effect. However, Heilongjiang Province is located in a cold area, and Trichoderma in other areas may not be able to fully exert its biocontrol function due to the limitation of low temperature conditions in cold areas. Therefore, it is necessary to isolate and identify Trichoderma strains that are suitable for low temperature conditions. [0003] Co...
