The invention relates to the technical field of biology, and discloses a moringa extract as well as a preparation method of the moringa extract and a moringa feed additive. According to the preparation method, water is added into moringa leaves, the pH value and the temperature are reduced, then, biological enzymes are adopted for enzymolysis, next, heating digestion is adopted to obtain water extraction liquid, ethanol precipitation is carried out after water extraction liquid concentration, obtained precipitates are the moringa extract, the biological enzymes are protease, cellulose and pectinase, and the protease is papain, pepsase, trypsin or serrapeptass. The enzymolysis effects of the specific protease, cellulose and pectinase is utilized for hydrolyzing large blocks of complicated-molecular-structure ingredients of the moringa leaves per se into smaller water-soluble high-bioavailability small molecular active substances, and then, high-yield and high-quality moringa extracts are obtained through a water extraction and ethanol precipitation method.

The invention discloses a method for preparing a germanium-enriched phellinus igniarius fermentation product. The method comprises the following steps: inoculating activated phellinus igniarius into a liquid seed culture medium with a moringa oleifera extract and cultivating to obtain a phellinus igniarius liquid strain; firstly, inoculating the phellinus igniarius liquid strain into a solid culture medium with hemp fimble leaf zymolyte, sugar beet pulp, germanium-enriched yeast and tea seed cake and cultivating to obtain germanium-enriched phellinus igniarius solid culture I; and inoculating the phellinus igniarius liquid strain into the liquid culture medium with germanium-enriched phellinus igniarius culture I, germanium-enriched yeast and gorgonian zymolyte and cultivating to obtain the germanium-enriched phellinus igniarius liquid fermentation product. An exogenous additive beneficial to organic germanium and germanium polysaccharide metabolism is added at the stages of solid fermentation and liquid fermentation; as an exogenous additive, the culture product of phellinus igniarius at the solid fermentation stage is added to the liquid fermentation stage to be recycled; through co-cultivation of the solid fermentation stage and the liquid fermentation stage, the content and the activity of the organic germanium and phellinus igniarius germanium polysaccharide in the final phellinus igniarius fermentation product are greatly increased.

The invention discloses a water purifying agent for a pond. The water purifying agent is mainly prepared from the following raw materials: potassium sulphate, acrylamide, calcium aluminate powder, activated carbon, moringa oleifera extractives, lignin, ferric sulfate, nanometer titania, modified kieselguhr and chitosan. The water purifying agent for the pond, disclosed by the invention, can effectively increase the dissolved oxygen in water, improve water quality and absorb and degrade organic matters in water; the water purifying agent is high in antibacterial efficiency; and the water purifying agent has the advantages of high safety, no toxicity or pollution and high stability. The pond water, treated with the water purifying agent for the pond, can meet the requirements of agricultural irrigation for crops.
