Embodiment 1

[0033] Study on the Symbiotic Ratio of Bradyrhizobium BASWS and Bacillus thuringiensis BtR05 in Peanut

[0034] (1) Cultivation of Bradyrhizobium BASWS and Bacillus thuringiensis BtR05 in peanut

[0035] Bradyrhizobium peanut BASWS medium is YMA medium, the formula is 10 g sucrose, 1 g yeast powder, MgSO 4 ·7H 2 O 0.2 g, K 2 HPO 4 0.5 g, NaCl 0.1 g, CaCl 2 0.05 g, sodium molybdate (0.5% solution) 4.0ml boric acid (0.5% solution) 4.0ml, H 2 O 1 000 mL, pH 6.8-7.0.

[0036] BtR05 slant and shake flask medium is LB. The fermentation medium is: 2% corn flour, 6% soybean flour, 1% sucrose, 0.5% (NH4) 2SO4, 0.2% K2HPO4, 0.2% KH2PO4, 0.03% MgSO4??7H2O, pH7.0-7.5.

[0037] (2) Toxicity determination of bradyrhizobium BASWS and Bacillus thuringiensis BtR05 on grubs

[0038] The 3rd instar larvae of grubs were treated by spraying method.

[0039] Spraying method: spray different concentrations of Bacillus thuringiensis BtR05 and Bradyrhizobium peanut BASWS all over the grub bo...

Abstract

The invention discloses a compound rhizobia agent and its preparation and application. In the present invention, peat soil is used as carrier, ammonium molybdate, peanut seedling powder, γ-polyglutamic acid, sucrose, calcium carbonate, and organic silicon are used as synergistic aids, and peanut Bradyrhizobium BASWS and Bacillus thuringiensis BtR05 fermentation liquid Made into a powder, the effective bacterial count is 1-400 million / g of Bradyrhizobium peanut BASWS and 600 million / g of Bacillus thuringiensis BtR05. This preparation can not only effectively control grubs, but also significantly increase peanut yield.

Description

technical field [0001] The invention relates to the technical field of preparation of biological bacteria agents, in particular to a compound rhizobia agent and its preparation and application. Background technique [0002] Peanuts are grown all over the country, mainly distributed in Liaoning, Shandong, Hebei, Henan, Jiangsu, Fujian, Guangdong, Guangxi, Sichuan and other provinces (regions). Among them, Shandong Province has the largest planting area and the largest output. [0003] In recent years, with the continuous expansion of peanut sowing area, the harm of underground pests has become more and more serious. Among them, grubs are currently the biggest pests that harm peanuts. According to the survey, grubs cause an annual loss of more than 20% of the peanut yield, serious or even extinct (Zhou Shuai, Su Ruifeng, et al. Peanut underground pests - comprehensive control technology of grubs [J]. Seed Industry Guide, 2009 .). Bacillus thuringiensis ( Bacillus thuringi...
