Abstract

The invention discloses a preparation method for algal oligosaccharide-containing carbon-based organic fertilizer for rowan crops. The preparation method comprises the following steps: treating algae,namely, cleaning fresh or dried marine alga plants and soaking the cleaned marine alga plants for 12 hours; preparing an alga liquid, namely, grinding the soaked algae into slurry and then filteringto remove large solid; performing enzymolysis on the alga liquid, namely, placing the alga liquid into an enzymolysis tank, adding bacilli, regulating the pH value to be neutral, and performing enzymolysis; performing centrifugal purification, namely, treating the alga liquid into a centrifugal machine for treating after the enzymolysis is completed, performing centrifugal treatment for 5,000 to 6,500 rpm, performing centrifugal treatment for 5 to 8 minutes, and then, concentrating a supernatant by a film evaporation technology to prepare an algal fertilizer liquid. According to the preparation method, charcoal and the alga liquid which is purified from the algae are added into the organic fertilizer to prepare the algal oligosaccharide-containing carbon-based organic fertilizer; oligosaccharide can serve as a regulator for plant growth and regulate the organic fertilizer and the soil so as to promote the absorption of the rowan crops to the organic fertilizer; therefore, good growth of the rowan crops is ensured.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizer preparation, in particular to a method for preparing a carbon-based organic fertilizer containing seaweed oligosaccharides for rowan crops. Background technique [0002] Organic fertilizers are carbon-containing materials that are mainly derived from plants and (or) animals and applied to the soil to provide plant nutrition as their main function. It is processed from biomass, animal and plant waste, and plant residues to eliminate toxic and harmful substances, and is rich in a large number of beneficial substances, including: a variety of organic acids, peptides, and rich nutrients including nitrogen, phosphorus, and potassium. nutritional elements. It can not only provide comprehensive nutrition for crops, but also has long fertilizer effect, can increase and renew soil organic matter, promote microbial reproduction, improve soil physical and chemical properties and biological activi...
