A kind of oldenlandia diffusa Initial culture base and preparation method thereof
Technical field
The present invention relates to oldenlandia diffusa tissue cultivating and seedling technical field more particularly to a kind of oldenlandia diffusas to be just commissioned to train
Support base and preparation method thereof.
Background technology
Oldenlandia diffusa (Hedyotis diffusa Willd), which is that Rubiaceae is annual, hangs down loosely draft, high 15-50cm, root
It is elongated, branch, white flower.Stem is slightly rectangular or oblate cylindricality, Glabrous send out multi-branched from base portion, and in spring at florescence, kind is careful
Small yellowish-brown;It can receive for two seasons within 1 year, spring sowing August is received, and autumn planting is received November.It is grown in the area of 800 meters of height above sea level, is grown in water more
Field, ridge and moistening spaciously.It is mainly distributed on the areas such as domestic Fujian, Guangdong, Hong Kong, Guangxi, Hainan, Anhui, Yunnan;
Its bitter, light, cold in nature, primary efficacy is clearing heat and detoxicating, dispersing swelling and dissipating binds, promoting urination and removing dampness, the diseases such as venomous snake bite, and discovered in recent years is white
Flower HERBA HEDYOTIS DIFFUSAE has preferable effect, quantity larger cancer and hepatitis.
But oldenlandia diffusa is mostly wild, family's kind is seldom, and wild oldenlandia diffusa adulterant is more, there is corymbose hedyotis herb, fine flower
Auricled Hedyotis Herb, sealwort, sandwort, carpet weed, adulterant can be distinguished when fresh by tiny plant morphological characteristics, but dry product and seed are difficult
Distinguish the true and false.
And traditional Hedyotidis Diffusae breeding method is that oldenlandia grass seed is directly seeded into crop field, such sowing is deposited
In problems with:
(1) seed quality is lighter, and growing way can be influenced by sowing uneven, closeer place;
(2) big field weed is more, is mixed with adulterant kind and is easy to be doped into oldenlandia medicinal material or seed;
(3) crop field is by temperature, and the influence of humidity, germination rate and survival rate are relatively low.
