Description
[technical field]
The present invention relates to Chinese medicine planting technology fields, and in particular to a kind of this method for promoting Hawthorn Seeds germination.
[background technique]
Hawthorn is rosaceae hawthorn deciduous tree, is stone fruit, caryoplasm is hard, and pulp is thin, and taste is slightly sour puckery.Fruit can give birth to
Preserved fruit fruitcake is eaten or made, can be used as medicine after drying, is the distinctive dual-purpose of drug and fruit tree species of China, there is reducing blood lipid, blood pressure, heart tonifying, resist
The effects of cardiac arrhythmia, while being also the good medicine of spleen benefiting and stimulating the appetite, relieving dyspepsia, phlegm reduction of blood circulation promoting, hernia, blood stasis full to chest diaphragm spleen,
The diseases such as amenorrhoea have good curative effect.Flavone compound Vitexin in hawthorn is a kind of stronger drug of antitumaous effect, mentions
Object is taken to have certain effect the internal growth of cancer cells of inhibition, proliferation and infiltration metastasis.
Currently, the main modes of reproduction of hawthorn has vegetative propagation and sexual propagation, vegetative propagation often with cutting propagation and is transferred
The method for connecing breeding.Propagation by grafiting is can to make stock using the seedling or axillary seedling of seminal propagation, is connect using bud or scion grafting
Or be abutted against, master is connected in bud.Vegetative propagation still be unable to do without the young plant that seminal propagation obtains.However Hawthorn Seeds belong to strong property
Seed, Germination period is long, and germination is difficult, the reason is that impermeability, the physiological dormancy phenomenon of embryo and the natural inhibitors matter of kind shell
