Embodiment 1

[0015] Raw materials: 10kg of stevia leaf waste residue, 15kg of stems, quicklime, microbial composite strains (composed of nitrogen-fixing bacteria, phosphorus-solubilizing bacteria, potassium-solving bacteria, photosynthetic bacteria, actinomycetes, microorganisms producing agricultural antibiotics, yeast, bacillus, Bifidobacteria, lactic acid bacteria, Clostridium butyricum and other beneficial microorganisms, the number of beneficial viable bacteria is more than 2 billion / g), inorganic salts (sodium selenite 26.3g, germanium dioxide 4.3g, zinc sulfate heptahydrate 13.2g, borax 52.0g), urea 1kg, made into 30kg;

[0016] step:

[0017] 1) Take the leaf waste residue and stem stems extracted from Stevia rebaudiana and grind them separately, the particle size is 30-50 mesh, mix the powder of leaves and stems, and maintain the moisture content. Put the raw materials into a cooking tank, add water and cook for 2 hours at a temperature of 70°C, and the liquid enters the storage ...

[0021] Determination of total solids of stevia biological growth agent

[0022] 1) Suspension and supernatant adopt ISO 2173-78 "Refractometer method for the determination of soluble solids in fruits and vegetables and their products". Mix the sample thoroughly, squeeze out the filtrate with four layers of gauze, discard the first few drops, and collect the filtrate.

[0023] 2) Dip 2 to 3 drops of the test solution with a glass rod, drop it on the center of the prism surface of the refractometer, quickly close the prism, and let it stand for 1 min, so that the test solution is uniform without bubbles and fills the field of vision. Align the light source and observe the objective lens through the eyepiece. Adjust the indicator gauge to divide the field of view into light and dark parts, and then rotate the fine-tuning screw to make the boundary between light and dark clear, and make the dividing line just on the cross point of the objective lens. Read the percent or refracti...

Abstract

The invention discloses a method for preparing a stevia rebaudiana biological growth promoting agent and belongs to the field of agriculture and comprehensive utilization. In the preparation method, the stevia rebaudiana biological growth promoting agent is prepared by taking stevia rebaudiana waste residues and stevia rebaudiana stems obtained after stevia is extracted as raw materials and adding inorganic salt with trace elements and microbial composite strains for carrying out fermentation. The stevia rebaudiana biological growth promoting agent prepared by the method can be used as a fertilizer and a feed additive. When the stevia rebaudiana biological growth promoting agent is used as the fertilizer, the yield of crops and sweetness can be promoted and soil can be improved. When the stevia rebaudiana biological growth promoting agent is used as the feed additive, the quality and the yield of animal meat can be promoted and the antiviral ability of animals is improved. The stevia rebaudiana biological growth promoting agent has the characteristics of high efficiency, low cost, no toxicity, no residues, environmental protection and the like. The method for preparing the stevia rebaudiana biological growth promoting agent has high application value.

Description

technical field [0001] The invention relates to a preparation technology for preparing a biological growth agent by using stevioside-extracted stevia leaf waste residue as a raw material, belonging to the field of agriculture and comprehensive utilization. Background technique [0002] At present, Stevia rebaudiana is mainly used in industrial extraction of stevioside, and the leaf residue after extraction cannot be effectively utilized, resulting in waste of resources and environmental pollution. Studies have shown that the leaf residues from which stevioside has been extracted still contain more plant protein, fiber and trace elements, which can be converted into humus when buried in the soil, and part of the inorganic salts can be converted into organic salts to promote the absorption of plants; in addition, Because the waste residue has a sweet taste, it can be given to animals as a feed additive, which can enhance the palatability of the feed and increase the weight of ...
