Production technology of compound microorganism bacterium agent for resisting bacterial wilt of eggplant

Abstract

The invention provides a production technology of a compound microorganism bacterium agent for resisting bacterial wilt of an eggplant. The production technology is characterized in that raw materials of a fertilizer comprise the following components: 15-20 parts of bacillus mucilaginosus, 15-20 parts of trichoderma harzianum, 15-20 parts of streptomyces microflavus, 10-35 parts of chitosan oligosaccharide, 10-15 parts of vegetable oil sludge, and 10-15 parts of plant ash; three probiotics are mixed by thallus preparation, material mixing, pelletizing of compound bacteria, coating of the vegetable oil sludge at the first layer, coating of plant ash at the second layer, and coating of chitosan oligosaccharide at the third layer; the three probiotics are separated from the antibacterial compound which is chitosan oligosaccharide and play each function to the maximum. According to the production technology, the antagonism and disinfecting effect of the microorganism to bacterial wilt and the induced resistance of chitosan oligosaccharide to the eggplant are utilized to realize the prevention and control of bacterial wilt; the compound microorganism bacterium agent has the advantages of being free from pollution, environmentally friendly, low in cost, and long-lasting in effect.

Description

Technical field [0001] The invention belongs to the technical field of fertilizer processing, and specifically relates to a production process of a composite microbial inoculum resistant to eggplant bacterial wilt. Background technique [0002] Eggplant, Solanum (scientific name: Solanum melongena L.) Solanaceae, Solanum plant. Eggplant erect branches herb to subshrubs, up to 1 meter tall, branchlets, petioles and pedicels are all branched by 6-8-(10), flat or short-stalked stellate hairs, branchlets are mostly purple (wild There are often prickles), and the hair will gradually fall off as it grows old. The leaves are large, ovate to oblong-ovate, and the petiole is about 2-4.5 cm long (wild prickly). The fertile flower is solitary, the flower stalk is about 1-1.8 cm long, and the hair is dense. The shape and size of the fruit vary greatly. The shape of the fruit is long or round, and the colors are white, red, and purple. Fruits can be eaten as vegetables. The roots, stems...

AI Technical Summary

Problems solved by technology

[0005] The prevention and treatment of eggplant bacterial wilt has a certain history, especially the biological control of eggplant bacterial wilt is the focus of current research, such as the patent application number 201010608576.8 of Nanjing Agricultural University, which can prevent and control eggplant bacterial wilt. Microbial organic fertilizer, using self-isolated Bacillus subtilis Ⅱ-36 to add to the organic fertilizer to make bio-organic fertilizer to prevent eggplant bacterial wilt, has the disadvantage of single strain and ineffective effect

Another example is application number 201510132794.1, a disease-resistant drug for eggplant bacterial wilt. The disclosed disease-resistant formula is prepared from Chinese herbal medicines, resulting in a waste of Chinese medicine resources.

In addition to adding antagonistic bacteria to fertilizers, the above patents do not add chitosan oligosaccharides, a beneficial ingredient that can improve the resistance of eggplants, and without production treatments such as sticking and coating, they cannot achieve long-term disease resistance. Invention can solve this problem well
