High-yielding cultivation method for rhizoma pinelliae

Abstract

The invention discloses a high-yielding cultivation method for rhizoma pinelliae. The method comprises the steps: selecting intermontane gentle-slope-region small flat land, which is high in altitude and not high in sunshine intensity and is loose, fertile and moist, as a planting base, carrying out sterilization on seed stems prior to sowing so as to lower the occurrence of root rot, adopting tuber spring sowing so as to increase the germination percentage and survival rate of the rhizoma pinelliae, carrying out scientific field management and timely topdressing, carrying out first-time topdressing after seedling emergence, then, carrying out topdressing repeatedly according to conditions of seedlings, carrying out irrigation and drainage earth-up so as to keep soil moist, crushing soil at edges of furrows during earth-up, uniformly spreading crushed soil to furrow faces, and leveling the soil by hands so as to prevent water accumulation; and carrying out timely bud picking, carrying out rational fertilizer application and carrying out disease and insect pest control. The high-yielding cultivation method has the beneficial effects that the seed stems are sterilized prior to sowing so as to lower the occurrence of root rot; the tuber spring sowing is adopted, and the seed stems are strictly selected, so that the germination percentage and survival rate of the rhizoma pinelliae are increased; and scientific field management, rational fertilizer application and disease and insect pest control are carried out, so that the occurrence of diseases and insect pests of the rhizoma pinelliae is lowered, and the yield is increased.

Description

technical field [0001] The invention relates to the technical field of planting Chinese medicinal materials, in particular to a cultivation method of pinellia. Background technique [0002] Pinellia is a perennial herbaceous plant of Araceae. The tubers are used for medicinal purposes. Spicy in the mouth, warm in nature. It has the functions of invigorating the spleen and harmonizing the stomach, drying dampness and resolving phlegm, reducing adverse flow and relieving vomiting, dispelling lumps and resolving stagnation. Mainly produced in Sichuan, Hubei, Guizhou, Zhejiang, Shandong Heze, Jiangsu, Shanxi Xinjiang and other provinces. Pinellia pinellia is the main raw material for the production of various Chinese medicine decoction pieces, preparations and decoctions for relieving cough and reducing phlegm.

Problems solved by technology

Pinellia products on the market have always been mainly provided by the wild. Due to the reclamation and utilization of barren hills and idle land in the past few years, and the extensive application of chemical fertilizers, pesticides and herbicides to the fields by farmers, the wild environment of pinellia has been severely damaged, especially in recent years. The wild resources are gradually reduced due to continuous and unrestrained mining by farmers in the place of origin. At present, the cultivation of pinellia in various parts of my country has not yet formed a scale, resulting in a serious shortage of marketed products.
