Nutritional type biological tablet

Abstract

The invention discloses a nutritional type biological tablet which comprises the following components by weight percent: carrier kieselguhr and bacillus amyloliquefacien X-278 fermentation liquor at a massic volume ratio of 1:1.5, 15% of glucose serving as a carbon source, 30% of groundnut meal serving as a nitrogen source and 20% of starch slurry serving as an adhesive. An accelerated breakdown test is performed on a sample, the viable content of the sample is detected regularly, and the viable content of the sample is kept at 107cfu / g after 200 days. The nutritional type biological tablet has the characteristics of short development period, low cost and simple process, and can be used for performing large-scale production. Since nutrient substances are added, the tablet is capable of realizing self propagation after being applied to soil, so that the field dosage is greatly reduced in comparison with fermentation liquor and solid bacterial manure, the lasting period is prolonged, and the package cost and the transportation cost are lowered.

Description

technical field [0001] The invention relates to a nutritional biological tablet for preventing and controlling plant diseases. Background technique [0002] Formulation processing is a key factor restricting the development of biopesticides, especially in the process of storage and use, the impact of each component in the formulation on the biocontrol activity of live bacteria is a particularly important factor in the processing of biopesticide formulations. Hebei Agricultural University applied for a patent in 2011 as "a solid microbial fertilizer and its preparation method" with the patent number 201110303507.0. The laboratory and field efficacy tests of Bacillus amyloliquefaciens X-278 fermentation liquid and solid bacterial fertilizer have proved that the bacteria has a good control effect on cotton and has a certain growth-promoting effect on cotton. However, studies have found that the use of fermented liquid for field experiments shows that the stability of the liqui...

Problems solved by technology

However, studies have found that the use of fermented liquid for field experiments shows that the stability of the liquid dosage form is poor, the antibacterial activity decreases during storage, it is not easy to preserve, and the frequency of application is high; although the solid fermentation product can be directly applied and the post-treatment is simple, it will There are still some problems in its large-scale use in the prevention and control of plant diseases, such as too much dosage, low bacterial content, easy pollution, and high cost
