preparation example Construction

[0030] (1) Preparation of bacterial suspension

[0031] Inoculate the Li-2013 single colony grown after streaking on the plate into the seed medium, culture at 40°C for 12 hours at 100 r / min, take 1 mL of the culture medium, centrifuge, wash twice with normal saline, and resuspend with 9 mL of physiological in salt water.

[0032] (2) Ultraviolet-Lithium Chloride-Diethyl Sulfate Compound Mutagenesis

[0033] The bacterial suspension was placed on a sterile plate, stirred and irradiated for 100s under a UV lamp with a distance of 30cm and a power of 15w. The irradiated bacteria solution was diluted and spread on the lithium chloride plate after gradient dilution, and the bacteria solution without ultraviolet irradiation was diluted and spread on the plate as a control. Wrap the uniformly coated plate above with black cloth or newspaper, incubate at 40°C for 48 hours, screen out the plate with the largest ratio of hydrolysis circle to colony diameter on the plate that grows co...

Embodiment 1

[0052] A kind of compound fertilizer, the array of parts by weight becomes: 8 parts of yeast inoculum, 8 parts of colloid bacillus inoculum, 8 parts of Bacillus megaterium phosphate solubilizing inoculum, 12 parts of Bacillus subtilis culture, 3 parts of Aspergillus awamori culture, Plant Lactobacillus agent 3 parts.

[0053] The strains used are as follows:

[0054] Bacillus subtilis subsp CGMCC7926

[0055] Lactobacillus plantarum CICC20764

[0056] Aspergillus awamori (Aspergillus awamori) CGMCC3.6484

[0057] Saccharomyces cerevisiae selected cicc1526, cicc1413, and the strains were purchased from China Industrial Microorganism Culture Collection Center.

[0058] For the production method of yeast inoculum, refer to Xiao Dongguang's "Production and Application Technology of Saccharomyces cerevisiae Active Dry Yeast", published by Inner Mongolia People's Publishing House in 1994.

[0059] The preparation method of Awamori Aspergillus agent:

Abstract

The invention discloses a compound fertilizer and a preparation method thereof. The compound fertilizer is composed of the following ingredients in parts by weight: 5-10 parts of a yeast agent, 5-10 parts of a colloid bacillus microbial agent, 5-10 parts of a phosphors-resolving bacillus-subtilis microbial agent, 10-15 parts of bacillus subtilis culture, 1-5 parts of aspergillus awamori culture and 1-4 parts of a lactobacillus plantarum agent. The fertilizer provided by the invention is rich in nutrition and high in organic matter content. The compound fertilizer provided by the invention is capable of meeting the production requirements of organic food. The fertilizer provided by the invention is formed by fermenting compound microorganisms, and thus is capable of improving the micro-ecological environment of soil and proving good conditions for the growth of crops.

Description

technical field [0001] The invention relates to a compound fertilizer and belongs to the technical field of agricultural fertilizers. Background technique [0002] The application of chemical fertilizers plays an important role in the increase of agricultural production. However, due to the long-term application of chemical fertilizers, the shortage of organic fertilizers and the imbalance of various nutrients in the soil cause the farmland ecological environment, soil physical and chemical properties and soil microbial flora to be damaged to varying degrees. . At the same time, it also affects the quality of agricultural products to a certain extent. "Fruits are not sweet, melons are not fragrant" is the manifestation of this situation. Fertilizer pollution has become a major public hazard in the world today. Agricultural experts have unanimously called for reducing the amount of chemical fertilizers to control the environment. An industry expert and academician Chen Wen...
