Embodiment Construction

[0021] In order to make the content and advantages of the invention more clear, a kind of seedling raising technology that is easy to survive high-density cuttings of Polygonum multiflorum provided by the present invention will be described in detail with examples in combination with specific examples:

[0022] 1. Materials and methods

[0023] This experiment was carried out on January 12, 2017 at the base of Shenwu Pharmaceutical Company in Hubei Province, Shiyan City, Danjiangkou City, Dingjiaying Town, and Raozupu Village. The annual Polygonum multiflorum stems are provided by the company itself.

[0024] Prepare annual Polygonum multiflorum stems, pruning pliers, alcohol, pruning pliers, bamboo strips, transparent nylon film, pots, ropes, tap water, rooting powder, electronic balances, labels, and tillers. Among them, the bamboo sticks are made of the same year's bamboo, with a length of 175.3cm and a diameter of 1.1cm; the transparent nylon film is made of agricultural ...

Abstract

The invention discloses a seedling-raising method for increasing the high-density survival rate of stem-cutting polygonum multiflorum, which is a technology used for increasing the survival rate of stem-cutting polygonum multiflorum in unit area. The technology is characterized in that upper and lower cuts of cutting strips are cut into smooth and oblique-smooth states and located from the closest stem node about 2-3 cm and 1.5-2 cm respectively; tap water or a solution of a rooting powder is utilized for soaking the cutting strips to the height of 3-5 cm above the lower cuts for 15 min and respectively cutting the cutting strips according to the presence of fibrous roots on the lower cuts; and inserting the cutting strips until the node closest to the lower cuts to be inserted into a seedbed substrate, depth being 2.5-4 cm and row spacing being 2 cm. The rooting powder (with the concentration of 25g/7.5kg water) is invented by Yongj Zhongshan Fertilizer Industry Co., Ltd. (GB/T17419-2010, amino acid greater than or equal to 100g/L, Fe+Zn+B greater than or equal to 20g/L). The seedling-raising method for promoting the high-density survival rate of stem-cutting polygonum multiflorum has the following beneficial effects: before cutting, steps of soil selection and preparation and steps of watering, film covering, daily management after cutting are performed such that polygonum multiflorum stems are neatly cut into seedbeds in a highly-efficient manner; and a solid foundation is laid for large-area promotion and cultivation of polygonum multiflorum.

Description

technical field [0001] The invention relates to the technical field of practical cultivation of medicinal plants, in particular to a seedling raising technology for improving the high density and high survival rate of Polygonum multiflorum stem cuttings. Background technique [0002] He Shou Wu ( Polygonum multiflorum Thunb. ), Polygonaceae, Polygonum, alias Shouwu, Chishouwu, Goblin. Its roots and rhizomes have the effects of nourishing the liver and kidney, nourishing the heart and calming the nerves, respectively, and are precious medicinal materials in traditional Chinese herbal medicine in my country. Polygonum multiflorum is cold-resistant and can survive the winter in the field. It is not strict with the soil and avoids waterlogging. At present, the propagation methods of Polygonum multiflorum include seed propagation, division propagation, and cutting stem propagation. Seed propagation will lead to uneven offspring plants, large differences in yield and quality be...
