Description
Technical field
The invention belongs to pig-breeding technical field, it is related to a kind of roughage containing sweet potato vine and its application.
Background technology
Sweet potato is not strange for us in daily life, either as crops, food or feed, but it is red
The aerial part of potato is but had ignored by us.The aerial part of sweet potato is referred to as sweet potato vine, includes leaf, stem and flower.Sweet potato
Stem is properly termed as climing or rattan again.The fertility of soil plants phase and planting density and also has a great impact to stem length, and the surface of stem has
Latex dust is distributed in skin portion in fine hair, can secrete the milk of white.When adopting ipomoea batatas seedling, if the milk of seedling is more, table
Ipomoea batatas seedling nutrition is illustrated compared with horn of plenty.The digua fig stem and leaf of Partial Species, sweet potato stem and leaf can be used as medicinal material.Sweet potato leaves are also known as pachyrhizus leaf, i.e.,
Leaf in sweet potato growth course on stem can harvest in the southern four seasons, common are chicken feet shape, five claw types, heart-shaped etc.,
Petiole color is viridescent, green, also there is purple.Sweet potato leaves are more known relative to sweet potato stem, and it is edible to can be used as food materials.
Sweet potato leaves have dispelling toxicity, detoxicating by related research discovery, reduction blood glucose, raising immunity, defaecation diuresis, slow down aging, prevent
The functions such as yctalopia.It is autumn after sweet potato maturation that we are generally edible, the tender leaf of ground seedling stem top part.Sweet potato vine is liked
Joyous illumination, in the case of illumination abundance, sweet potato leaves leaf color is deeper.Sweet potato vine is more drought-enduring, the environment of warm and moist is liked, to soil
It is of less demanding, preferably the good sandy loam of loose, fertile, drainage performance and sand mold soil.
Sweet potato is relatively common, and for a long time, wast rural area only digs sweet potato edible in the time of sweet potato harvesting
Or sell etc., and for sweet potato vine, people are then to lose sweet potato leaves in the ground together with rattan, or directly take away and feed house
Poultry.In recent years, as sweet potato leaves have gradually gone on the dining table of people, the nutritive value of sweet potato vine is also gradually sent out by people
