508 results about "Micronutrient" patented technology

Micronutrients are essential elements required by organisms in small quantities throughout life to orchestrate a range of physiological functions to maintain health. Micronutrient requirements differ between organisms; for example, humans and other animals require numerous vitamins and dietary minerals, whereas plants require specific minerals. For human nutrition, micronutrient requirements are in amounts generally less than 100 milligrams per day, whereas macronutrients are required in gram quantities daily.

Cold pressing and physical refining process of camellia oil

The invention relates to a cold pressing and physical refining process of camellia oil. The cold pressing and physical refining process of the camellia oil is characterized by comprising the following steps of: (1) selecting ripe camellia seeds and drying the ripe camellia seeds by microwave vacuum until the water content is 3-6%; and conveying the dried camellia seeds into a huller to be hulled;(2) carrying out cold pressing on the hulled camellia seeds to squeeze the camellia oil, wherein the temperature of a barrel is in a range of 100-150 DEG C and an oil output temperature is in a rangeof 80-120 DEG C; (3) removing solid impurities in the squeezed camellia oil through a plate and frame filter press; (4) winterizing the camellia oil filtered by the plate and frame filter press at a temperature in a range from below 5 DEG C to 5 DEG C; (5) carrying out molecular distillation on the winterized camellia oil to remove free fatty acid, oil peroxide products, moisture and other low-boiling-point substances from the camellia oil; and (6) taking a mixture of carclazyte, active carbon and aluminum oxide as a filtering medium to filter; and removing impurities and pigments of the camellia oil treated by the molecular distillation to obtain the finished product. The cold pressing and physical refining process of the camellia oil has the advantages of environmental friendliness, high oil yield, and high retention ratio of micronutrients in finished oil.

Polymorphic nitrogenous fertilizer and preparation method thereof

The invention discloses polymorphic nitrogenous fertilizer and a preparation method thereof. The polymorphic nitrogenous fertilizer comprises, by weight, 13-18 parts of urea, 63-65 parts of ammonium sulfate, 13-15 parts of ammonium chloride, 3-4 parts of animal hairs and feathers, 14-16 parts of modified attapulgite, 0.6-0.8 part of zinc sulphate monohydrate, 0.2-0.4 part of micronutrients fertilizer, 3-8 parts of ferrous sulfate, 0.3-0.5 part of nitrogen-fixing bacteria, 2-4 parts of modified nanocarbon, 1-3 parts of fructus cnidii, 5-7 parts of pomegranate tree roots and 9-11 parts of willow leaves. The feathers and the like are hydrolyzed by acid to form amino acid, secondary and trace elements are chelated, carboxymethyl cellulose increases a chelation structure of the secondary and trace elements so as to facilitate effective utilization of the secondary and trace elements, and invalid release of the secondary and trace elements is reduced. The polymorphic nitrogenous fertilizer is suitable for crops of wheat, rice, corn, soybean, rape and the like, can urge the wheat and the rice to turn green rapidly, be much in shooting and longing resistant and enhance chill-proof, drought-resistant and disease and insect resistant capacity, and enables cotton and linen crops to enhance tension and strength of fiber and improve output and quality remarkably.
