Description

A kind of nutritive medium promoting sweet potato to grow and preparation method thereof

Technical field

The present invention relates to a kind of nutritive medium promoting sweet potato to grow and preparation method thereof, belong to agricultural plantation technology field.

Background technology

Ipomoea batatas, original name sweet potato, has another name called fennel taro, sweet storage, sweet potato, Zhu's potato, golden potato etc., belong to tubiform floret order, convolvulaceae annual herb plant, blade is generally width egg shape, long 4-13 centimetre, wide 3-13 centimetre, corolla pink, white, lavender or purple, mitriform or funnel-form, long 3-4 centimetre, capsule is avette or oblate, has pseudoseptum, is divided into Room 4.Ipomoea batatas rich in proteins, starch, pectin, Mierocrystalline cellulose, amino acid, VITAMIN and several mineral materials, have the reputation of " life prolonging food ".Sugar degree reaches 15%-20%.There is the effect such as anticancer, cardioprotection, prevention pulmonary emphysema, diabetes, fat-reducing.Be commonly called as pachyrhizus again.Ming Dynasty's LI Shi-Zhen Compendium of Material Medica note has " sweet potato qi-restoratives, spleen benefiting and stimulating the appetite, strong kidney yin ", and says the longevity of marine people's food.The traditional Chinese medical science is good medicine depending on Ipomoea batatas.

Moisture containing 60%-80% in Ipomoea batatas block root, the starch of 10%-30%, the sugar of about 5% and a small amount of protein, grease, Mierocrystalline cellulose, hemicellulose, pectin, ash grade, if be converted into 0.5Kg grain with 2.5Kg fresh sweet potatoes to calculate, in addition to fats, protein, carbohydrate equal size are all high than rice, flour for its nutritive ingredient, and in Ipomoea batatas, protein composition is more reasonable, essential amino acids content is high, and the Methionin content in Ipomoea batatas particularly comparing shortage in Cereals based food is higher.In addition contain abundant VITAMIN (E, B1, B2, C) in Ipomoea batatas, its starch is also easy to be absorbed by the body.

Annual herb, circular, the oval or fusiform piece of root of underground part tool, the shape of block root, color of the leather and yellowish pink because of kind or soil different and different.The flat sleeping or rising of stem, occasionally has winding, multi-branched, cylindrical or tool rib, green or purple, and by thin pubescence or without hair, stipes is raw adventive root easily.Blade shape, color are often different because kind is different, also sometimes have different leaf on same plant, full edge or 3-5(-7) split, avette or the wire lanceolar of sliver width egg shape, triangular shape, blade base is heart-shaped or be bordering on truncate, and top is gradually sharp, and two sides is dredged pubescence or is bordering on without hair, leaf look has dark green, yellowish green, purple green etc., and the color of top is one of feature of kind; Petiole is different in size, long 2.5-20 centimetre, by thin pubescence or without hair.Cyme armpit is raw, has 1-3-7 flower to be gathered into umbrella shape, the long 2-10.5 centimetre of peduncle, slightly sturdy, without hair or sometimes by thin pubescence; Bract is little, lanceolar, long 2-4 millimeter, top awns point or suddenly point, caducous; The long 2-10 millimeter of bennet; Sepal Long Circle or ellipse, Length discrepancy, the long 7-10 millimeter of outer sepal, the long 8-11 millimeter of interior sepal, top becomes awns pointed suddenly, without hair or thin raw echinid; Outside is without hair; Stamen and style built-in, filigree base portion is by hair; Ovary 2-4 room, by hair or sometimes without hair.Flowering habit is different with kind and growth conditions, and some kinds are easily bloomed, and some kinds can be bloomed when drought, and, sunshine high at temperature commonly blooms in short area, and temperature lower ground district is seldom bloomed.Seed 1-4 grain, usual 2, without hair.

Chinese invention, application number: 201310676150.X discloses a kind of macroelement, trace element and water composition, and described nutritive medium comprises: the nutritive medium of four water-calcium nitrate, saltpetre, primary ammonium phosphate, magnesium sulfate heptahydrate, ammonium nitrate, boric acid, copper sulfate, water glass, magnesium sulfate, cobalt chloride, nickelous chloride, potassium sulfate, Repone K, disodium ethylene diamine tetraacetate, iron vitriol, four water manganous sulfates, cupric sulfate pentahydrate, ammonium nitrate, calcium carbonate, potassiumiodide, sodium-chlor, ferric sulfate, plumbic acetate, Trisodium Citrate composition.But this nutritive medium is not establish for Ipomoea batatas plantation specially.Therefore develop a kind of nutritive medium tool promoting sweet potato to grow to be of great significance.
