Method for interplanting polygonatum kingianum

Abstract

The invention discloses a Polygonatum interplanting cultivation method. The land is flattened into a plurality of planting units arranged in parallel, and three parallel ridges are formed on each planting unit. The length direction of each ridge is east-west direction; the three ridges are respectively For the first Polygonatum planting ridge, the second bean planting ridge, and the third medicinal material planting ridge; on the first Polygonatum planting ridge, select a small section of tuber with two nodes and one terminal bud, and carry out hole sowing at a plant spacing and row spacing of 20cm, and cover with soil 3 ‑5 cm, water after a little suppression, and then water once every 3‑5 days; plant bean plants on the second bean planting ridge according to the season; plant angelica or Gastrodia elata on the third medicinal material planting ridge Above, field management: during the flowering period of Polygonatum, spray selenium-enriched nutrients evenly on the leaves with a sprayer in the morning and evening in fine weather; in mid-March of the year before the harvest of Polygonatum, apply selenium fertilizer to the soil, and the aboveground part will wither in autumn or harvest in the next spring dig. The method not only reduces the risk of market fluctuations, but also improves the yield and quality of Polygonatum.

Description

technical field [0001] The invention relates to the technical field of medicinal material cultivation, in particular to a method for interplanting Polygonatum interplanting. Background technique [0002] Polygonatum Polygonatum belongs to Liliaceae Polygonatum, the main species are Polygonatum Polygonatum, Polygonatum Dianensis and Polygonatum Polyflora, which are mainly published in central and western mountainous areas and hills in my country. According to the shape, it is commonly known as rhubarb essence, chicken head polygonatum, turmeric essence, etc. It is better to have large pieces, plump, yellowish white, and transparent cross-section, and those with bitter taste should not be used as medicine. Polygonatum is used for both medicine and food, and has always been a valuable Chinese herbal medicine. The main components of its contents are Polygonatum polysaccharides, steroidal saponins, anthraquinones, alkaloids, cardiac glycosides, lignans, multivitamins, trace elem...

AI Technical Summary

Problems solved by technology

However, the planting cycle of Polygonatum is relatively long, and it can only be harvested in the third year of planting. The market of medicinal materials fluctuates greatly, which leads to an increase in the risk of expected income of Polygonatum. The existing planting technology of Polygonatum is not perfect, and the ability to resist market fluctuations is poor, and the field management technology is not standardized. , resulting in a decline in the yield and quality of Polygonatum
