Production method of eggs with high organic selenium content and low cholesterin content

The invention provides a production method of eggs with high organic selenium content and low cholesterin content, which relates to a production method of eggs. The method comprises the following steps: (1) preparing a Chinese herbal medicine mixture capable of enhancing the metabolism function of hens, selenium-enriched feedstuff A and selenium-enriched feedstuff B, feeding the selenium-enriched feedstuff A to laying hens of an age of 30 to 50 days until the age of the laying hens reaches 70 days, feeding the selenium-enriched feedstuff B to the laying hens, and stopping the feeding until the age of the laying hens is 120 days before the egg laying; and (2) preparing selenium-enriched feedstuff C, and continuously feeding selenium-enriched feedstuff C to the laying hens of the age of 120 days adaptively fed in the first step (after 15 to 20 days, the organic selenium content in the eggs is between 3.5 mg / kg and 8.36 mg / kg through detection, and the cholesterin content is between 150 mg / 100 g and 300 mg / 100 g). The invention can stably obtain the eggs with the effects that the organic selenium content in each egg is not lower than 200 mug, the egg with the cholesterin content between 150 mg / 100 g and 300 mg / 100 g, the egg contains more than 40 kinds of nutriments necessary to human bodies, the nutriments have balanced proportion and sufficient content, in addition, the health condition of the hens is good, and the yield is stable.

Durable super-hydrophobic coating and preparation method thereof

The invention relates to a durable super-hydrophobic coating and a preparation method thereof. The preparation method comprises the following steps: 1) hybrid paint preparation: under low-speed mechanical stirring condition, adding micro nano particles, hydrophobic resin and a curing agent in a volatile organic solvent successively, performing high speed stirring and then ultrasonic dispersion to obtain the hybrid paint; 2) coating semi-solidification: coating the surface of a base material with the hybrid paint and performing semi-solidification; and 3) complete solidification: immersing the semi-solidified coating in a mixed immersion solution of the curing agent and the volatile organic solvent, taking the coating out, and drying the coating to obtain the durable super-hydrophobic coating having good wear resistance. The preparation method has no special requirement for a substrate material and its shape, the coating is suitable for various common base material surfaces such as metal, glass, timber and concrete, the equipment is simple, operation is easy, the cost is low, large-area construction is realized, and the coating has large application value on super-hydrophobic fields of self-cleaning, anticorrosion, mildew resistance, ice and frost resistance, and oil-water separation.

New-generation full-element chelated-state food-grade liquid bacterial fertilizer and preparation method thereof

The invention discloses a new-generation full-element chelated-state food-grade liquid bacterial fertilizer and a preparation method thereof, relates to an organic fertilizer containing bacterial cultures or hyphae, and aims at providing a liquid bacterial fertilizer and a preparation method thereof. Multiple high-salt-resistant strains are reasonably matched and cooperate with multiple chelating solutions, and therefore after the bacterial fertilizer is applied, effective ingredients in the bacterial fertilizer can be efficiently utilized for a long term. The new-generation full-element chelated-state food-grade liquid bacterial fertilizer is prepared from 4-6 parts of composite microbial strains, 4-5 parts of molasses, 0.4-0.6 part of bran, 0.05-0.1 part of carbamide, 0.05-0.1 part of sodium chloride, 0.01-0.02 part of tea leaves, 7-9 parts of a composite sugar alcohol-trace element chelating solution, 20-26 parts of an ammonium polyphosphate-nitrogen-phosphorus-potassium chelating solution, 3-5 parts of an organic acid-medium and trace element chelating solution and 45-50 parts of water. After the liquid bacterial fertilizer is applied, form transformation of soil nutrients can be promoted, plant metabolism can be enhanced, and pathogenic bacteria can be resisted. The liquid bacterial fertilizer is applied to the field of agricultural planting.

High-nutrient microbial bacterium composite fertilizer and production method thereof

The invention discloses a high-nutrient microbial bacterium composite fertilizer and a production method thereof. The high-nutrient microbial bacterium composite fertilizer comprises the following components in parts by weight: 16-190 parts of double-wall layer composite microbial bacterium microcapsules (containing 3-5 parts of composite microbial bacteria), 150-450 parts of monoammonium phosphate, 0-400 parts of urea powder, 100-200 parts of potassium chloride, 200-350 parts of ammonium chloride, 20-100 parts of ammonium bicarbonate, 0-150 parts of ammonium sulfate and 0-50 parts of attapulgite. The production method comprises the following steps: adsorbing the microbial bacteria by adopting germ powder thereof, performing first wall layer embedding by adopting a chemical cross-linking method, performing second wall layer embedding by adopting a spray drying process, and finally coating on the surface of chemical fertilizer granules, and split charging. The composite fertilizer is sufficient in nutrient and high in viable count, so that the microbial bacteria can be slowly released, yield increase of crops is guaranteed, the incidence rate of insect pests is reduced, and soil hardening caused by application of chemical fertilizers is improved.
