Embodiment 1

[0015] Embodiment 1. According to the mass ratio, 100 parts of acrylamide superabsorbent resin, 0.1 part of 10% glycerol aqueous solution, 10 parts of 20% fulvic acid salt solution, and 1 part of EM solution with a concentration of 1% were added to the In the mixer, the next raw material is added after each feeding is stirred evenly; then the mixed system is placed in an airflow drying box, the temperature is raised to control the temperature at 60°C, and dried for 2 hours; then crushed and sieved to obtain highly active biological nutrition Water retaining agent products.

Embodiment 2

[0016] Example 2: Graft 100 parts of starch-grafted acrylic acid superabsorbent resin according to mass ratio, 0.5 parts of 5% methylenebisacrylamide solution, 20 parts of 10% fulvic acid salt solution, and 2% EM solution 5 Parts are added to the mixer in turn, and the next raw material is added after each addition is stirred evenly; then the mixed system is placed in an airflow drying oven, and the temperature is raised to control the temperature at 55 ° C, and dried for 1 hour; then crushed and sieved, that is Obtain highly active bio-nutrient water retaining agent products.

Embodiment 3

[0017] Example 3: Graft 100 parts of cellulose to acrylic acid superabsorbent resin in mass ratio, 2 parts of 1% methylenebisacrylamide solution, 50 parts of 15% fulvic acid salt solution, and 10% EM solution Add 0.1 parts into the mixer in turn, and add the next raw material after each addition and stir evenly; then put the mixed system in a drying oven, raise the temperature and control the temperature to 50°C, and dry for 1.5 hours; then pulverize and sieve, that is Obtain highly active bio-nutrient water retaining agent products.

Abstract

The invention provides a high activity bio-nutritive water retention agent, which adopts super absorbent resin as host crystal, uses 1-10% glycerin solution as surface cross linker, simultaneously compounds 10-20% humate / fulvic acid salt solution and 10% high activity biological bacteria (like EM bacterium fluid) to prepare high activity water retention agent. The invention has relatively high biological activity, and is applied to agriculture and forest industry, and improves production, strengthens effect, protects environment and greatly improves soil-improving ability. The invention adopts compounding biological agents with high activity under acidity condition, which is beneficial for survival and propagation of strains. The invention does not kill strains when dries at low temperature, and is beneficial for dormancy and storage of strains.

Description

technical field [0001] The invention belongs to the technical field of water and soil conservation, and relates to a high-activity biological nutrient water-retaining agent and a preparation method thereof, which are mainly used in dry farming, water-saving agriculture and forestry soil improvement, water and soil conservation, desertification (rocky desertification) control, seed treatment and the like. Background technique [0002] Water-retaining agent is a functional polymer material, which can not only fully absorb irrigation water or natural rainfall when applied to the soil, effectively prevent the leakage and loss of water in the soil, improve water use efficiency, but also promote the formation of soil aggregates. Formation, improve soil void structure, prevent soil erosion. Therefore, water-retaining agents are widely used in agriculture, forestry and other water-saving fields.
