Abstract
The invention discloses a microbe fertilizer microbial inoculum with high water absorbing and retaining properties and a production method thereof. The microbial inoculum is prepared from the following raw materials in percentage by weight: 10-70 percent of macromoleclar polymer saponified fluid, 10-60 percent of microbial fermenting bacterial liquid, 1.0-10 percent of mineral powder, 0.2-5.0 percent of OP-10 dispersing agent and cross-linking agent the addition of which is 0.2-10 percent of the weight of the macromoleclar polymer saponified fluid. The macromoleclar polymer saponified fluid is formed by carrying out partial neutralization reaction on a macromoleclar polymer and sodium hydroxide and the neutralization degree is 50-90 percent. In the invention, by adopting a normal-temperature cross-linking process, since the reaction is carried out at normal temperature, the activity of microbial strains cannot be influenced; and meanwhile, the microbial inoculum is coated in a low-density network of resin with high water-absorbing property, the resin with high water-absorbing property is uniformly mixed with the microbial strains, the separation and delamination phenomena cannot generate, the survival rate of the strains can be ensured and the service performance of fertilizer can be improved.
Description
Technical field
The present invention relates to a kind of microbe fertilizer microbial inoculum, particularly a kind of microbe fertilizer microbial inoculum and preparation method thereof with high water absorbing and retaining performance.
Background technology
Microbial fertilizer is a newer research field of soil microbiology, and its researchdevelopment has crucial meaning for the Sustainable development green agriculture and the ecological agriculture, and is subjected to people day by day and pays close attention at large.
Microbial fertilizer typically refers to the particular product that a class contains the living microorganism bacterium, be applied in the agriculture production, crop can obtain fertilizer effect, in the production process of this effect, the living microorganism bacterium that contains in the goods can be with the nitrogen of nonabsorbable material of some crop such as invalid attitude in the soil, phosphorus, element decomposition and inversion such as potassium become the effective nitrogen that can directly be absorbed by crop, phosphorus, nutritive substances such as potassium, and in its metabolic process, produce plant stimulatory material matter, antibiotics etc., thereby improve the crop alimentary situation, reduce disease and pest, impel the healthy and strong growth of crop, reach the purpose of volume increase.In microbial fertilizer, have only these useful microbial bacterias to be under vigorous breeding, the metabolic situation, the conversion of material and the formation of useful metabolite just can be carried out, therefore, beneficial microorganism number of viable and vigorous vital movement are the basis and the prerequisite of its validity in the microbial fertilizer.The vital movement of microbial bacteria also is subjected to the influence of factors such as edatope factor such as moisture content, temperature, oxygen, pH value and redox potential except that the needs energy and nutriment.
Water is indispensable material in the microbial nutrition, and it is not only a kind of nutritive substance, or the main chemical constitution of microorganism cells.Water is the good solvent of nutritive substance and meta-bolites, and nutritive substance and meta-bolites are all by dissolving be dispersed in the cell of coming in and going out in the water.Water is the medium that various biochemical reactions are carried out in the cell, and participate in many biochemical reactions, so the microorganism optimum is lived in a humid environment, in exsiccant soil, microorganism can only be kept survival under dormant state, this also is that microbial fertilizer is in the not good enough reason of arid area validity.
If we in manufacturing the process of microbial fertilizer, can select good bacterial classification, and the environment that they provide nutritious, moisture content is abundant can be, the validity of microbial fertilizer will be improved undoubtedly widely.
