[0008] (3) Freeze-dried bacteria dosage form: no adsorbent, white powder, the bacteria content is dozens of times higher than that of peat, but it is widely used in production few
[0010] (1) There is a lack of high-efficiency rhizobia strains and strain resources. Many manufacturers are using the same strain for the strains, and the fertilizer variety is single; on the other hand, the strains used Improperness will also bring potential safety hazards. Some manufacturers' production strains are put into production without formal identification, which is also an inappropriate behavior;
[0011] (2) The production equipment is obsolete. Many production plants are transformed from closed down small enzyme preparation factories, monosodium glutamate factories, citric acid factories, etc. The equipment itself Low efficiency, high energy consumption, barely produced, no long-term development plan;
[0012] (3) The technical process is backward. Some manufacturers believe that as long as there are microbial fertilizer strains and corresponding culture media, microbial fertilizers can be produced. advanced monitoring and testing methods, and some are even small workshop-style production methods

Abstract
The invention discloses a special humic acid-urea coated rhizobium fertilizer for soybean and a preparation method thereof and belongs to the technical field of special fertilizers for crops. The special humic acid-urea coated rhizobium fertilizer for soybean comprises the following raw materials in parts by weight: 50-350 parts of humic acid-urea coated rhizobium agent composition, 200-500 parts of 5% humic acid coated urea, 200-500 parts of triple superphosphate, 100-400 parts of potassium sulfate and 20-200 parts of calcium magnesium phosphate. Compared with the prior art, the fertilizer and the preparation method disclosed by the invention are an important measure for improving the yield and quality of the soybean, reducing the production cost, protecting the ecological environment and developing organic green agriculture and ecological agriculture.
Description
technical field [0001] The invention belongs to the technical field of special fertilizer for crops, and in particular relates to a special humic acid-urea coated rhizobia fertilizer for soybeans and a preparation method thereof. Background technique [0002] Crop nitrogen fertilizer comes from chemical nitrogen fertilizer and biological nitrogen fixation. Chemical nitrogen fertilizer has made a huge contribution to crop yield. However, chemical nitrogen fertilizer has high production cost, low utilization rate, and constantly destroys soil fertility and environmental ecology. It has become one of the obstacles to sustainable agricultural development. one. Biological nitrogen fixation is completely spontaneously carried out by organisms and microorganisms without providing any energy and equipment, so it reduces energy consumption, has no pollutant emissions, and is conducive to protecting the ecological environment. At the same time, due to the reduction and exemption of ...
