Method for seedling raising and cultivation of polygonatum kingianum on basis of seed breeding

Abstract

The invention discloses a method for seedling raising and cultivation of polygonatum kingianum on the basis of seed breeding. The method comprises the following steps that 1, berries of picked polygonatum kingianum are subjected to after-ripening for 20-25 days first, and pulp parts are removed to obtain seeds of polygonatum kingianum; 2, fertilization, ploughing, pest killing and sterilization are carried out on seedling raising land; 3, sowing is carried out; 4, soil is kept moist in a seedling period, and the shading rate is controlled to be 70-80%; 5, transplanting is carried out, whereinseedlings are transplanted in a planting area with the plant spacing of 25-35 cm and the row spacing of 30-45 cm, and the seedlings are watered once 3-5 days after transplanting; 6, management in a growing period is carried out, wherein the management includes water management, weeding, topdressing, control over the shading rate and top sealing to remove moss; 7, harvesting is carried out. The method achieves refined and standardized seedling raising of polygonatum kingianum, not only is the seedling raising time shortened, the survival rate of seedlings is increased, the quality of the seedlings is improved, but also the seedling rate is high, the incidence rate of diseases and pests is low, the growth speed is high, rhizomes of polygonatum kingianum after harvesting are thick and strong,the quality is good, and the yield is high.

Description

technical field [0001] The invention belongs to the technical field of planting Chinese herbal medicines, and in particular relates to a method for raising seedlings of Polygonatum yunnanensis based on seed breeding. Background technique [0002] Polygonatum, also known as Chicken Head Polygonatum, Yellow Chicken Vegetable, and Chicken Claw Ginseng, is a plant of the genus Polygonatum, which has the effects of nourishing the spleen, moistening the lungs, promoting body fluid, nourishing qi and nourishing yin, antibacterial, anti-aging, beautiful appearance, and strong energy. For diseases such as weak spleen and stomach, fatigue, dry mouth, lack of food, insufficient blood, and high blood pressure, external application of Polygonatum extract can treat athlete's foot. Polygonatum is mainly distributed and cultivated in North China, East China, South China, Central China and other provinces. Yunnan Polygonatum Polygonatum, also known as Sweet Polygonatum, is famous both at hom...

Problems solved by technology

At present, in the technology of artificially cultivating Polygonatum Diannian, seedling raising technology is the key to the current research. In the existing technology, the seedling raising technology of Polygonatum Diannian mainly includes two methods: seed propagation and rhizome propagation. The dormant period is longer, and the use of seeds for seedlings has the disadvantages of low germination rate and long seed propagation time, which greatly increases the cost of planting and is not conducive to the artificial large-scale planting of Polygonatum yunnanensis. Therefore, in the current artificial In cultivation, the propagation of seedlings mainly depends on rhizome propagation. Although the propagation period of this method is short, the propagation coefficient is low, the amount of rhizome is large, the cost of planting is also high, the disease resistance is not high, and the quality and output of the product cannot be achieved. Meet the expectation, it is not convenient for effective promotion of cultivation management
