Problems solved by technology

[0004] As sealwort is listed as one of the dual-purpose varieties of medicine and food, it is widely developed in food and health products, and its demand is increasing year by year. Wild resources can no longer meet market demand.
And the propagation of Rhizoma Polygonatum mainly relies on seed propagation and division propagation, and the seedling loss of division propagation is large, and germination rate is not high, and growth is slow, and general seed propagation production cycle is long, and germination rate is low, and general germination needs 2 years
At present, although domestic and foreign scholars have carried out relevant research on the reproduction methods of Polygonatum, they mainly focus on the tissue culture of Polygonatum, and it is limited to the experimental stage, and there is still a long way to go for production.

Embodiment 1

[0029] A method for growing seedlings of Polygonatum semen, comprising the following steps:

[0030] 1) In October, collect the Polygonatum fruit with blackened surface and mature landing, and store it at 0-20°C and humidity 75-85% until March next year;

[0031] 2) Take out the Polygonatum fruit, remove the pulp, take out the seeds, soak in 0.5% carbendazim solution for 1 hour, then take out the seeds and drain until the surface is dry. This step is completed in an environment without direct sunlight;

[0032] 3) Arrange the sand bed in the greenhouse, spread fine sand with a thickness of 8cm, and then spray gibberellin with a concentration of 0.5‰ at a spray density of 100ml / m 2 , and then sprayed with a concentration of 0.5‰ of naphthalene acetic acid, and the spray density was 100ml / m 2 ;

[0033] 4) Spread the seeds at a density of 8000 grains / m 2 , then spread fine sand with a thickness of 3cm, cover with a layer of straw, and water with a watering density of 800ml / m ...

Abstract

The invention discloses a seedling raising method for rhizoma polygonati seeds. The seedling raising method comprises the following steps: firstly, collecting rhizoma polygonati fruits in October; secondly, taking out the rhizoma polygonati fruits, removing fruit flesh and taking out seeds; thirdly, tidying sand beds in a greenhouse; fourthly, sowing the seeds; fifthly, sieving the germinated seeds by using a sieve with 10 meshes and continuously sowing the germinated seeds according to the fourth step; sixthly, tidying a seedbed in the greenhouse; seventhly, sieving rhizoma polygonati seedlings by using a griddle with 5 meshes in March to April of next year.

Description

technical field [0001] The invention relates to a method for raising seedlings, in particular to a method for raising seedlings of Polygonatum seeds. Background technique [0002] Polygonatum sibiricum belongs to the genus Polygonatum sibiricum in Liliaceae, and it is mainly distributed in Hebei, Shanxi, Shaanxi, Inner Mongolia and other places in my country. Under normal conditions, its wild resources are mainly distributed in forests, shrubs or hillside shade, at an altitude of 800-2800 meters. [0003] In "Flora of China", there are 31 species of Polygonatum genus recorded in my country, with a wide geographical distribution, but only three species of Polygonatum, Polygonatum multiflora and Polygonatum yunnanensis are included in the 2015 Pharmacopoeia. Polygonatum rhizome is used as medicine, mainly containing niacin, quinones, starch and polysaccharides and other components. Polygonatum is flat in nature and sweet in taste, and mainly has the functions of invigorating...
