Technical Field

The invention relates to the technical field of organic fertilizers, in particular to a mineral biological organic fertilizer.

Background

After a large amount of chemical fertilizers are used in the existing agricultural land, the problems of soil hardening, desertification, secondary salinization and the like are easily caused, and the cultivated area with seriously unbalanced nutrition is increased sharply. The deterioration of the ecological environment of soil causes the reduction of the activity of soil microorganisms, the sharp reduction of the quantity, the poor development of crop root systems, metabolic disturbance, increasingly poor stress resistance, frequent occurrence of plant diseases and insect pests, the over-use of pesticides by farmers and the over-standard accumulation of pesticide residues and other toxicants become problems which cannot be ignored. Among them, the effective method is to use organic fertilizers and microbial fertilizers to gradually replace the use of fertilizers.

The main substance in the organic fertilizer is organic matter, and the organic fertilizer is applied to increase the content of the organic matter in the soil. The organic matter can improve the physical, chemical and biological characteristics of soil, mature the soil and fertilize the soil. By applying the organic fertilizer, a plurality of organic colloids are increased, and a plurality of organic matters are decomposed and converted into the organic colloids by virtue of the action of microorganisms, so that the adsorption surface of the soil can be greatly increased, a plurality of adhesive substances are generated, soil particles are cemented to form a stable granular structure, and the water-retaining, fertilizer-retaining and air-permeable performances of the soil are improved.

The microbial fertilizer is a microbial living product which leads crops to obtain a specific fertilizer effect through microbial life activities and products thereof, and at present, the microbial fertilizer has irreplaceable effects on the aspects of fertilizing soil fertility, improving the utilization rate of chemical fertilizers, inhibiting the crops from absorbing nitrate nitrogen, heavy metals and pesticides, purifying and repairing soil, reducing crop diseases, promoting the decomposition and utilization of crop straws and municipal waste, protecting the environment, improving the quality of crop products, improving food safety and the like.

Chinese patent with application number CN 201510600232.5 discloses a microorganism controlled-release fertilizer, which comprises the following raw materials by weight percent: 9-30% of chitin, 0.3-6% of bacillus subtilis preparation, 6-15% of alginic acid, 10-15% of nitrogen fertilizer, 8-10% of phosphate fertilizer, 10-15% of potassium fertilizer and the balance of epoxy resin to 100%; wherein the total number of effective live bacteria of the bacillus subtilis preparation is more than or equal to 2 hundred million spores/g. The chitin, the bacillus subtilis and the alginic acid have good synergistic effect and controlled release function, can meet the nutrient requirement of crops in the whole growth period by one-time application, greatly reduces the fertilization operation cost and has good safety. However, the microbial controlled release fertilizer in the patent contains a large amount of chemical fertilizer, soil hardening is still easily caused under the condition of long-term use, and although the epoxy resin is beneficial to slow release, the epoxy resin also has a certain harm effect on soil.
