Propagation method capable of improving emergence rate, strong seedling rate and quality of polygonatum sibiricum red

Abstract

The invention discloses a propagation method capable of improving the emergence rate, strong seedling rate and quality of polygonatum sibiricum red, aiming at overcoming the defects that the existing polygonatum sibiricum red propagation technique is low in germination rate, long in breeding time, low in efficiency, poor in benefit, declined in quality and the like. According to the propagation method, polygonatum sibiricum red seeds which are collected in September and October are sealed for 6-10 days at the room temperature; the polygonatum sibiricum red seeds, which are stored in a sealing way and have fully rotten shells, are put into sand and are enabled to sprout at the temperature of 3-7 DEG C. The propagation method can be used for the sexual propagation of polygonatum sibiricum red used for producing a traditional Chinese medicine, can use the polygonatum sibiricum red seed resource to carry out large-scale sexual propagation, can maintain the natural quality of the polygonatum sibiricum red, increases the germination rate to 80% or more, is short in breeding time and high in efficiency, can increase the yield by 3500 kilograms per mu, and obtains good benefit.

Description

technical field [0001] The invention relates to a breeding method of the traditional Chinese medicine Rhizoma Polygonatum, in particular to a breeding method for improving the seedling emergence rate and quality of Rhizoma Rhizoma Polygonatum. Background technique [0002] Polygonatum sibiricum Red. is the dried rhizome of Polygonatum sibiricum Red., which is a plant of Liliaceae, Polygonatum sibiricum or Polygonatum multiflora. It has medicinal, edible, ornamental and beauty value. Its rhizome is used as medicine. It is flat in nature and sweet in taste. It is used to treat weakness of the spleen and stomach, fatigue, lack of energy, dry mouth, lack of food, dry cough due to lung deficiency, insufficient essence and blood, internal heat and thirst, etc. It is very effective for diabetes. [0003] According to the difference of the original plant and the properties of medicinal materials, Polygonatum Polygonatum is divided into three types: Polygonatum Polygonatum, Rhizoma ...

Problems solved by technology

[0007] The deficiency of the existing sealwort breeding technology is that the germination rate is low and the breeding time is long. It takes 2 winter dormancy to grow a true leaf. It takes 5-7 years from sowing to harvesting, and the germination rate is only 20%. Left and right, the efficiency is low, and the benefit is poor. In particular, tubers are generally used for asexual reproduction in artificial cultivation. There are few successful sexual reproduction techniques with high germination rate, and seed propagation is hardly adopted. So, the waste of seed resources is not conducive to Large-scale production and long-term asexual reproduction have caused the degradation of Huangpin species, the quality has declined, and the output has decreased
