Bio-fertilizer with water retention function and processing technology thereof

Abstract

The invention discloses a bio-fertilizer with water retention function and a processing technology thereof. The bio-fertilizer comprises the following components: an organic fertilizer, microbial fermentation broth, a mixture of nitrogen, phosphorus and potassium elements, medium and trace elements, an organic chelating agent and macromolecular water absorption and water retention resin. The processing technology includes: preparing the macromolecular water absorption and water retention resin; preparing the organic fertilizer; mixing all the above raw materials evenly to obtain a dispersion liquid; and spraying the dispersion liquid on an adsorbent, stirring the substances evenly and performing natural air drying, thus obtaining the bio-fertilizer with water retention function. Accordingto the bio-fertilizer, beneficial microorganisms are wrapped in the network of the macromolecular water absorption and water retention resin, and the loose and porous adsorbent is embedded among the network of the macromolecular water absorption and water retention resin to enlarge the access channels of beneficial microorganisms, water and the like, thus creating an appropriate living environmentfor beneficial microorganisms. The experimental result shows that the bio-fertilizer is more beneficial to the growth and development of crops.

Description

technical field [0001] The invention relates to the technical field of microbial fertilizers, in particular to a biological fertilizer with water retention function and a processing technology thereof. Background technique [0002] Agriculture is the basic industry of our country and has always occupied an important position in the national economy. For more than 30 years, my country's grain production has achieved remarkable growth. However, while increasing food production, long-term excessive use of chemical fertilizers has also brought about problems such as environmental pollution, soil compaction, soil fertility decline, ecological deterioration, and decline in the quality of agricultural products. In addition, the excessive use of chemical fertilizers also reduces the utilization rate of chemical fertilizers, resulting in increased agricultural costs and reduced production efficiency. At present, the utilization rate of chemical fertilizers in my country is about 30%,...

AI Technical Summary

Problems solved by technology

Since the superabsorbent resin is a granular solid, which has a different specific gravity from the microbial agent, and the water-absorbent resin itself has high water absorption performance, it is difficult to mix the two directly, which is not conducive to the growth of microorganisms, and the superabsorbent resin is also difficult to play a role. affect the use of fertilizers
