Sweet potato, commonly known as sweet potato, belongs to the genus Ipomoea of Convolvulaceae. Also known as Ganchu, Sweet Potato, Bamboo Tree, Sweet Potato, Fanru, Dried Sweet Potato, Jade Pillow Potato, Sweet Potato, Sweet Potato, Sweet Potato, Goose, Sweet Potato.
Sweet potato, panicum miliaceum, has round, oval or spindle-shaped roots in the underground part. The shape, skin color and flesh color of roots vary with varieties or soils. Stems procumbent or ascending, occasionally twining, multi-branched, cylindrical or angular, green or purple, sparsely pilose or hairless, and stems are prone to adventitious roots.
The shape and color of leaves often vary from variety to variety, and sometimes the shape of leaves is different on the same plant. Usually broadly ovoid, 4 to13cm long, 3 to13cm wide, all leaves or 3 to 7 lobed leaves, broadly ovoid, triangular oval or linear-lanceolate, heart-shaped or nearly flat at the base, tapering at the top, pubescent or nearly glabrous at both sides, leaves. Petioles vary in length, 2.5 to 20 cm long, sparse or glabrous.
Cymes axillary, 1 ~ 3 ~ 7 flowers cymose, peduncle 2 ~ 10.5 cm long, slightly stout, hairless or sometimes puberulent; Bracts are small, lanceolate, 2-4 mm long, with awns or acute tips, caducous; Pedicel length 2 to 10 mm; Sepals are oblong or oval, unequal in length, the outer sepals are 7 to 10 mm long, the inner sepals are 8 to 1 1 mm long, and the top suddenly becomes pointed, with no hair or sparse cilia; Corolla pink, white, lavender or purple, bell-shaped or funnel-shaped, 3 to 4 cm long, glabrous outside; Stamens and styles are embedded, and filaments are hairy at the base; Ovary 2-4-loculed, hairy or sometimes glabrous.
Flowering habits vary with varieties and growth conditions. Some varieties are easy to bloom, others will bloom when the climate is dry, which is common in areas with high temperature and short sunshine, and rarely blooms in areas with low temperature. The capsule is ovoid or oblate, with a false diaphragm and divided into 4 cells. Seeds 1 to 4, usually 2, glabrous. Because sweet potatoes are cross-pollinated, self-pollination often does not bear fruit, so sometimes they only bloom and do not bear fruit.
Sweet potato is a natural nourishing food with comprehensive nutrition, which contains protein, fat, polysaccharide, phosphorus, calcium, potassium, carotene, vitamin A, vitamin C, vitamin E, vitamin B 1, vitamin B2 and 8 kinds of amino acids.
High-quality feed: Sweet potatoes are high-quality feed for fattening pigs, which can be eaten alone or mixed with other grains, such as corn, green seeds, or grass and leaves. Leaves and vines can be eaten raw, dried and crushed, scalded with chaff and cooked. Eating corn 1 cooked potato chips alone or in combination 0 months before the pig is shaped (the bones are elongated) or slaughtered has a particularly good fattening effect, just like using a "fattening agent", which can generally gain 0.5 to 0.8 kilograms of meat every day. This is the successful experience of fattening pigs in Chenggu County, Shaanxi Province.
Widely used: potato chips are suitable for processing a variety of products, not only making soy sauce, candied fruit, caramel and calcium gluconate, but also brewing liquor and extracting alcohol. Calcium citrate can be produced from potato residue after starch extraction. Its starch is an important raw material for producing plasticizer and advanced water-absorbent resin.
Extraction of starch: Its starch can be eaten in a wide range. It can be mixed with all kinds of meat to make meatballs, steamed with flour, or made into cakes and stirred cold noodles alone.
