Embodiment 1

[0054] Example 1, using polyacrylic acid resin to prepare sodium polyacrylate type super absorbent and water-retaining microbial fertilizer inoculum.

[0055] Add 70kg deionized water and 7kgNaOH into a 200kg reactor, stir and dissolve under normal pressure, slowly add 18kg polyacrylic acid resin while stirring after cooling, then raise the temperature to 70°C±2°C, carry out hydrolysis and saponification reaction for 5 hours, and prepare into sodium polyacrylate hydrolysis saponification solution.

[0056] After cooling the sodium polyacrylate hydrolysis saponification solution to room temperature, add 30kg of mixed fermentation concentrate of Bacillus megaterium and Bacillus jelly-like (can use the concentrated mixed fermentation solution produced by Beijing Shuanglong Arms Technology Co., Ltd., the number of effective viable bacteria 4 billion pieces / ml), add 3kg montmorillonite powder (fineness≤200 mesh), 1kg zeolite powder (fineness≤200 mesh), 1.5kgOP-10 dispersant, fully ...

Embodiment 2

[0058] The polyisobutylene-maleic anhydride type superabsorbent and water-retaining microbial fertilizer bacterial agent is prepared by using polyisobutylene-maleic anhydride resin.

[0059] Add 60kg of deionized water and 4.2kg of NaOH into a 200kg reactor, stir and dissolve under normal pressure, slowly add 10kg of polyisobutylene-maleic anhydride resin while stirring after cooling, and then heat up to 80°C±2°C for hydrolysis and saponification reaction After 7 hours, polyisobutene-sodium maleate saponification solution was made.

[0060] After the polyisobutene-sodium maleate saponification solution is cooled to room temperature, add 35kg of Bacillus megaterium, Bacillus jelly-like, and Bacillus subtilis mixed fermentation broth (concentrated mixed fermentation broth produced by Beijing Shuanglong Arms Technology Co., Ltd. , the number of effective viable bacteria is 5 billion / ml), add 1kg peat powder (fineness ≤ 200 mesh), 3kg zeolite powder (fineness ≤ 200 mesh), 2kg OP-1...

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 [0001] The invention relates to a microbial fertilizer bacterial agent, in particular to a microbial fertilizer bacterial agent with high water absorption and water retention performance and a preparation method thereof. Background technique [0002] Microbial fertilizer is a relatively new research field of soil microbiology. Its research and development is of great significance to the sustainable development of green agriculture and ecological agriculture, and it has attracted more and more attention from people. [0003] Microbial fertilizers usually refer to a specific type of product containing active microbial bacteria. When used in agricultural production, crops can obtain a fertilizer effect. Substances that cannot be absorbed, such as ineffective nitrogen, phosphorus, potassium, etc., are decomposed and converted into effective nitrogen, phosphorus, potassium, etc. nutrients that can be directly absorbed by crops, and plant stimulating substances, an...
