Description
Technical field
The present invention relates to a kind of seedling breeding method of traditional Chinese medicine, specifically Yunnan Paris polyphylla Paris polyphylla var.yunnanensis (Fr.) Hand.Mazz. seed high efficiency seedling cultivating method.
Background technology
The seed development of Yunnan Paris polyphylla is incomplete, and the seed of fresh harvest does not have complete embryo, belongs to stupid col type seed.Under field conditions (factors), the seed germination of Yunnan Paris polyphylla needs through 2 winters, and about 18 ~ 22 months, emergence rate was also lower, and planting percent is just lower, less than 1%.In order to shorten the sprout time of Yunnan Paris polyphylla seed, a lot of scientific research institutions have carried out and have broken seed dormant research, and hormone and intermittent warming are the methods comparatively commonly used.These methods suitably shorten the sprout time of Yunnan Paris polyphylla seed, to raising emergence rate and can increase planting percent, not significant contribution.
After the Paris polyphylla seed sprouting of Yunnan, the transplanting survival rate of annual seedling is less than 10%, and the transplanting survival rate of biennial seedling is less than 50%, and the survival rate of 3 years raw seedling can reach more than 85%.Therefore, after Yunnan Paris polyphylla seed comes up, need 3 years foster, just can become commercial seedling and sell.Due to the restriction of resources and environment, it is low that few people study Yunnan Paris polyphylla seeding ratio, the reason of seedling difference.
Summary of the invention
The object of the invention is to the defect overcoming prior art, provide a kind of and improve the emergence rate of Yunnan Paris polyphylla seed and the Yunnan Paris polyphylla seed seedling-raising method of planting percent.
A method for Yunnan Paris polyphylla seed seedling-raising, said method comprising the steps of:
