Method for planting Polygonatum sibiricum

Abstract

The invention provides a method for planting Polygonatum sibiricum. The method has the characteristic of comprising the following steps of: (1) selection and preparation of a field; (2) treatment of aPolygonatum sibiricum rhizome: tearing the rhizome according to 2-3 sections, scratching the surface, performing sterilization, and then immersing the sterilized rhizome in a nutrient solution for 3-6 hours, wherein the nutrient solution comprises the following components of: 0.8-1 g / L of manganese sulfate, 1-1.6 g / L of potassium dihydrogen phosphate, 0.3-0.6 mg / L of zinc sulfate, 0.3-0.4 mg / L ofnaphthalene acetic acid and 0.1-0.2 mg / L of 6-benzyl purine; (3) planting of the Polygonatum sibiricum rhizome: putting one single treated rhizome in a matrix in a mode that bud scars are put upwards, performing cultivation for 1-2 days, and then putting the cultivated rhizome together with the matrix in a high ridge, wherein the matrix comprises the following components: in parts by weight, 30-40 parts of humus soil, 10-20 parts of peat, 2-6 parts of expanded perlite and 5-10 parts of moss; (4) management of the field; (5) management of topdressing; and (6) management of weeding and pests and diseases. The planting method has a high germination rate and a high germination speed of Polygonatum sibiricum, and is suitable for large-scale planting production.

Description

Technical field [0001] The invention belongs to the technical field of Chinese herbal medicine planting, and specifically relates to a method for planting Polygonatum. Background technique [0002] Polygonatum is a lily family plant Polygonatum. It is a commonly used traditional Chinese medicine. It was mainly used as a medicine in the past. Its market demand is small and the source is mainly from wild mining. However, with the continuous deepening of the application of Polygonatum in recent years, the use of Polygonatum has greatly expanded Wide, in addition to medicinal use, it can also be processed into preserves, beverages, health care products and skin care products, and used as animal feed additives, and can be cultivated as vegetables and ornamental flowers. Polygonatum is wild in damp mountain shrubs and forest edge grasses. It is hardy, and its seedlings can survive the winter in the field, but it is not suitable to grow in dry areas. Its seeds take a long time to germin...

Problems solved by technology

[0003] The reproduction of Rhizoma Polygonatum mainly depends on seed propagation and branch propagation. The seed reproduction cycle is long and the germination rate is not high. Generally, it takes 2 years to germinate. However, the traditional branch propagation also has the status quo of low germination rate and slow growth.

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.
