TL;DR: In this paper, a preparation method of polygonum multiflorum fiber used for spinning is described, which comprises the steps of: (1) sorting and cutting roots, and then soaking with water bath, and finally stripping a bast layer of the fiber by adopting a bast core separating method; and (2) carrying out pre-oxidation, washing, soda boiling, hydraulic power washing, oil feeding after dehydrating, removing oil water, fluffing and drying on the stripped bast of the polygonumm multiflorumm fiber rattan so as to obtain the poly
Abstract: The invention relates to a preparation method of polygonum multiflorum fiber used for spinning. The preparation method comprises the steps of: (1) taking polygonum multiflorum fiber rattan samples, sorting and cutting roots and then soaking with water bath, and finally stripping a bast layer of polygonum multiflorum fiber rattan by adopting a bast-core separating method; and (2) carrying out pre-oxidation, washing, soda boiling, hydraulic power washing, oil feeding after dehydrating, removing oil water, fluffing and drying on the stripped bast of the polygonum multiflorum fiber rattan so as to obtain the polygonum multiflorum fiber. According to the preparation method provided by the invention, the process is simple, the equipment requirement is low, the usage amount of chemical medicine is few and the production cost is low, and industrial popularization is facilitated, the polygonum multiflorum is utilized, so that waste material is changed into things of value, resource is saved, and the environment is protected; and the polygonum multiflorum fiber prepared by adopting the preparation method provided by the invention has good flexibility and spinning processability and can meet requirements of people to environment-friendly and ecological comfort pure fibers.

TL;DR: In this article, a planting method of polygonum multiflorum thund is described, which consists of selecting a planting land, preparing a soil, adjusting a soil pH, fertilizing a basal fertilizer, planting and managing according to the local environment, choosing a planting environment of no or little root weeds, and soil with stones, adequate water and a convenient drainage.
Abstract: The invention discloses a planting method of polygonum multiflorum thund. The method comprises selecting a planting land, preparing a soil, adjusting a soil pH, fertilizing a basal fertilizer, planting and managing; according to the local environment, choosing a planting environment of no or little root weeds, and soil with stones, adequate water and a convenient drainage; selecting a planting slope of the terrain in the 5 - 10 degrees; selecting high-quality red maple seedlings to plant in a furrow; selecting a tree height is 30 - 50cm, and red maple spacing is between 0.5 - 1m. The polygonum multiflorum thunb stems is planted in a furrow. The polygonum multiflorum thund stems and red maple seedlings are distributed by triangular. A pedunculatum is planted between every two plants in the furrow. The tree height is 30 - 50cm, and red maple spacing is 0.5 - 1m. The polygonum multiflorum thund stems and a barberry are interplanted, by taking 5 - 10cm height berberis seedlings, and polygonum multiflorum thund stems in a distance of 30cm, wherein a lemon balm and a yarrow are interplanted. The invention adopts a method of plant interplanting disinsection to reduce damage caused by the use of insecticides and pesticides to the environment and to avoid residues of pesticides on polygonum multiflorum thund.
