Planting method for pinellia ternata

Abstract

The invention discloses a planting method for pinellia ternate, and belongs to the technical field of cultivation techniques of traditional Chinese medicinal materials. The planting method includes a, selecting seeds; b, ditching on a field surface to complete soil preparation; c, seeding around spring equinox in the lunar calendar, bedding fabrics or cloth-shaped materials at the bottom and on two lateral surfaces of the filed surface, placing seed stems or germination-accelerated seed stems on screens of ditches at the intervals of 3-8cm, and covering the seed stems with mixed fat soil with 4-5cm thickness; d, managing the field; and e, during harvesting, drawing back the fabrics or the cloth-shaped materials which contact with the bottoms and two lateral surfaces of the ditches and turn out from the upper edges of the ditches from one side, raking earthnuts, substantial fibres and pinellia ternate tubers with soil into containers, screening, sorting out, classifying, processing and storing the tubers, the earthnuts and the fibres. The width of the fabrics or the cloth-shaped materials can meet the requirement that the fabrics and the cloth-shaped materials can contact with the bottoms and the lateral sides of the ditches and turn out 2-6cm respectively from the two upper edges of the ditches. The planting method has the advantages that growth of weeds around the pinellia ternata plants can be prevented, and the pinellia ternata is convenient to harvest; and especially, the earthnuts can be sorted out, so that yield and income can be increased.

Description

technical field [0001] The invention relates to a method for cultivating and planting medicinal plants, in particular to a method for planting pinellia, a Chinese medicinal material. Background technique [0002] Pinellia is Pinellia ternata (Thunb.) Berit., a plant of the Araceae family. It is used as medicine with dried tubers. It was first recorded in "Shen Nong's Materia Medica", and it is a commonly used traditional Chinese medicine that has been used blindly for more than 2,000 years. It has the effects of drying dampness and resolving phlegm, lowering adverse flow and relieving vomiting, dispelling lumps and resolving stagnation. The 2010 edition of "Chinese Pharmacopoeia" includes three forms of pinellia under the entry of medicinal materials, decoction pieces and processed products (French Pinellia, Jiang Pinellia, and Qing Pinellia). Anhui is one of the main pinellia production areas, including Yin Pinellia, Shu Pinellia, Ying Pinellia, and Jiao Pinellia. Among th...

Problems solved by technology

This method requires intertillage and weeding in the field management steps. Because the pinellia plants are short, the soil must be loosened and weeded frequently during the growth period to avoid grass shortages. Because the roots of Pinellia grow around the tubers, their roots are concentrated in the surface soil at a depth of about 10cm. Therefore, weeding should be done early, small, and in addition, and because Pinellia is planted in early spring with this method, and mulched with plastic film, at the same time as the seedlings emerge, small thistle, purslane, black lotus, foxtail, horsetail Tangcao, goosegrass, teff, Cyperus cyperus, amaranth, convolvulus, ashweed, plantain and other more than ten kinds of weeds were also unearthed, and the number is large, which often makes it difficult to emerge after the film is removed, affecting the The output of pinellia; this method adopts the traditional harvesting method in the harvesting step, and the harvesting efficiency is low; Pinellia also has extremely short underground stems, which can produce 1 to 2 roots and a large number of fibrous roots on the stems. The root tips of larger roots often rot, and the roots can also reproduce. The traditional harvesting method not only fails to harvest the tubers completely, but also makes it difficult to sort out the tubers and a large number of fibrous roots, which has a great impact on the harvest.
