Seedling growing method for polygonatum sibiricum seeds

Abstract

The invention provides a seedling growing method for polygonatum sibiricum seeds. The method comprises the following steps: selection, soaking, fine sand treatment, storage, germination acceleration,seeding and seedling-stage management. According to the method provided by the invention, the polygonatum sibiricum seeds are subjected to soaking and fermentation, cold storage on a culture medium and breeding in soil, then the hibernation period of the polygonatum sibiricum seeds can be greatly shortened, and the breeding process is thus shortened; the breeding process is simple, a large quantity of polygonatum sibiricum seedlings can be provided quickly, the tuber propagation of polygonatum sibiricum is reduced, the planting cost is lowered, artificial planting of polygonatum sibiricum is promoted, excavation of wild polygonatum sibiricum is reduced, and the income of the planters is increased; moreover, through the breeding method provided by the invention, the germination rate of theobtained polygonatum sibiricum seeds is relatively high, thus popularization is facilitated.

Description

technical field [0001] The invention relates to a method for growing seedlings of Polygonatum semen. Background technique [0002] Polygonatum (rhizoma polygonti), Liliaceae, a medicinal and edible plant of the genus Polygonatum. The ones with large lumps, plumpness, yellowish-white color, and transparent cross-section are the best, and the ones with bitter taste cannot be used as medicine. The "Shen Nong's Materia Medica" in the Han Dynasty, the "Compendium of Materia Medica" in the Ming Dynasty, and the "Qingyang County Chronicles" in the Qing Dynasty all have records of the efficacy of herbal diet. Polygonatum has the functions of invigorating qi and nourishing yin, invigorating the spleen, moistening the lungs, and benefiting the kidney. It is used to treat weakness of the spleen and stomach, fatigue and fatigue, dry mouth and lack of food, dry cough due to lung deficiency, insufficient essence and blood, internal heat and thirst, etc. It is also very effective for dia...

Problems solved by technology

In addition to the high investment threshold and high cost of traditional cultivation, such land is also extremely scarce. Not only is the cost rising rapidly, but in order to achieve large-scale cultivation, most areas have almost no land to choose from.

On the other hand, in non-staple grain-producing areas, especially in poor and backward areas, left-behind women and the elderly have become the main labor force engaged in planting, and the quality of labor and the intensity of suitable labor have deteriorated sharply, and it is difficult to adapt to traditional Huang Jing deep digging and Huang Jing. harvest

[0004] The development of traditional Polygonatum has always had the problems of high labor intensity, especially the difficulty of excavation, high production cost, and poor consistency of finished products; the conditions for land selection are harsh, the available land is scarce, and the corresponding high land cost is also an important factor restricting development; Labor prices are rising rapidly, land for staple food is increasingly in short supply, and the market is increasingly demanding on the consistency of the finished products of Polygonatum, how to achieve low-cost and low-labor-intensity production of Polygonatum becomes more and more important

[0005] Due to factors such as long breeding time for Polygonatum seeds, low reproduction rate, and difficult collection of seeds, the cost of artificial large-scale planting has greatly increased. However, in traditional artificial planting, asexual reproduction is mainly used, and rhizome propagation is used. After multiple generations of reproduction, it degenerates It is more serious and susceptible to viruses. In addition, a large amount of nutrients in the sealwort seeds will be consumed during the sand storage process, which is not conducive to the germination of the seeds when the seeds are sown. In addition, the lack of refined breeding management makes the germination rate of the seeds Only about 60%, therefore, the present invention proposes a kind of Polygonatum seed seedling raising method to solve the deficiencies in the prior art
