Embodiment 1

[0033] 1. Materials and methods

[0034] 1.1 Isolation and storage of bacteria

[0035] In this example, rhizosphere soil samples were collected for the isolation of bacteria, and the rhizosphere soil samples were collected from facility greenhouses during the pepper growing season in Beidi Village, Yongchang County, Gansu Province. Randomly select 25 points in the sampling plot, take the root system of a healthy pepper plant and shake it gently with your hands until the soil on the root system does not fall off, collect the soil that has not fallen off on the root system, mix it and bring it back with a sealed bag, and remove it with a 0.2cm mesh sieve Pepper remains, air-dried at room temperature. Weigh 10g of soil sample into a conical flask filled with 90mL sterilized water, shake it for 10min, and make 10 -1 Concentration of soil suspension, let it stand until the soil particles settle, then draw 1mL supernatant and transfer it into a test tube filled with 9mL sterilize...

Abstract

The invention belongs to the technical field of microorganisms, and particularly discloses paenibacillus terrae YC16-08 and application thereof. A preservation number of the paenibacillus terrae YC16-08 is CGMCC No.16181. By virtue of test research, the paenibacillus terrae YC16-08 has an antagonism effect for phytophthora capsici, botryis cinerea, colletorichum acutatum, rhizoctonia solani, fusarium oxysporum, fusarium solani and fusarium verticillioides. The paenibacillus terrae YC16-08 can generate siderophore, amylase, protease, pectinase, cellulase, IAA and NH3, and has nitrogen fixationcapacity and phosphorus dissolving capacity.

Description

technical field [0001] The invention belongs to the technical field of microorganisms, and in particular relates to a strain of Paenibacillus terreus YC16-08 and its application. Background technique [0002] Demand for crops to feed a growing population is increasing, and likely will continue for decades. However, due to factors such as environmental degradation, destruction of biodiversity, and loss of soil fertility, agricultural production has been greatly reduced, resulting in insufficient food supply for humans. At the same time, the impact and restrictions on the application of chemical fertilizers and pesticides have raised public concerns about the sustainability and safety of the food supply. These factors provide impetus to identify alternatives to chemical pesticides, such as biopesticides. Microbial pesticides, probiotics, or microbial inoculants are live microorganisms applied to soil, seeds, or rhizomes that can colonize the rhizosphere and / or plant tissue, ...
