Microbial organic fertilizer and compound fertilizer, and preparation methods thereof

Abstract

The invention relates to microbial organic fertilizer and compound fertilizer, and preparation methods thereof, belonging to the field of fertilizer production. Firstly, chicken manure, grass peat, brown sugar, carbamide, powdered rock phosphate, rice bran or wheat bran and zymocyte are proportionally mixed and then are fermented, and the microbial organic fertilizer can be prepared by adding functional bacteria to the mixture after the fermentation; and inorganic fertilizer, medium trace elements, humic acid, biologic protein and functional bacteria are proportionally added to the prepared microbial organic fertilizer, the obtained mixture is thoroughly stirred and then is processed by granulation, polishing, drying and screening, thereby obtaining the compound fertilizer. The functional bacteria include photosynthetic bacteria, lactic acid bacteria, microzyme, Gram positive actinomycetes, phosphate-solubilizing bacteria, potassium-solubilizing bacteria and nitrogen-fixing bacteria. The fertilizer prepared by the invention can effectively improve the ecology environment for the growth of crop, increase the quality of the crop, inhibit plant diseases and insect pests and kill pathogenic bacteria, and the medium trace elements contained are of many types, are sufficient in quantities and present high fertilizer efficiency; and during application, the fertilizer just needs to be applied for once, thereby saving labor power and causing no environmental pollution.

Description

technical field [0001] The invention relates to a fertilizer and a production method thereof, in particular to a microbial organic fertilizer and a compound fertilizer and a production method thereof, belonging to the field of fertilizer production. Background technique [0002] In recent years, due to the rise of the large-scale chicken industry, a large amount of chicken manure has become a new pollutant. In order to turn waste into treasure, microbial organic compound fertilizers or microbial organic-inorganic compound biological fertilizers made of chicken manure as raw materials have emerged as the times require. . [0003] The Chinese patent publication number is CN101417897A, and the patent of invention published on April 29, 2009 discloses a kind of microbial organic compound fertilizer. The main components of this kind of microbial organic compound fertilizer are chicken manure, corn stalk powder, coal slime, microbial Fermentation agent, urea, potassium sulfate, c...

Problems solved by technology

However, this kind of fertilizer lacks other beneficial functions except for increasing a certain amount of organic matter content and increasing limited trace elements. The resistance and immunity of the plant, and the trace elements contained are not many types, the amount is small, and the fertilizer efficiency is not high. When using it, it needs to apply fertilizer many times, which is a waste of manpower and easy to pollute the environment.
