Technology for planting codonopsis pilosula in barren soil in southern China

Abstract

The invention discloses a technology for planting codonopsis pilosula in barren soil in southern China. The technology comprises the following steps that land selection and preparation are conducted, specifically, wet sandy soil or sand soil with irrigation conditions or soil rich in humus or a downsun shady slope is selected as a seedling field; a reproduction method is determined, specifically, seed treatment, seedling and direct seeding as well as transplantation are conducted; field management is conducted, specifically, sun shades are removed, and thinning, tillage and weeding, topdressing, drainage and irrigation as well as propping are conducted; pest and disease damage and prevention and treatment thereof are determined, specifically, a cultivator should pay attention to prevention and treatment of root rot, the rust disease and downy mildew among the diseases as well as pay attention to prevention and treatment of grubs, cutworms, mole crickets, red spiders and aphids among insets damage; the seed reserving technology is conducted, specifically, two-year-old plants have more flowers and seeds and are high in yield, good in quality and suitable for seed reserving; harvesting and processing are conducted, specifically, harvesting is conducted when the aboveground parts of the plants are withered and become yellow in autumn; and storage is conducted, specifically, the aboveground parts are stored in ventilated dry places, and moth proofing, mildew proofing and bleeding proofing are achieved.

Description

technical field [0001] The invention relates to the field of planting medicinal materials, in particular to the technique of planting Codonopsis ginseng in poor lands with prescriptions. Background technique [0002] Codonopsis Codonopsis is a herbaceous vine, the whole plant has white latex and a special odor. It is born in mountainous forests and bushes. The flowering period is from July to September, and the fruiting period is from September to October. Contains steroids, triterpenoids, dandelion alcohol acetate, nicotinic acid, codonopsis acid, vanillic acid and other substances and glycosides such as syringin and tangshenoside, sugars such as syringaldehyde, inulin and fructose, and asparagus 17 kinds of amino acids such as amino acid and threonine, and 14 kinds of inorganic elements such as iron, zinc, copper and manganese.

AI Technical Summary

Problems solved by technology

Codonopsis pilosula has strong adaptability and likes mild and cool climates. Different growth periods have different requirements for water, temperature and sunlight. The suitable temperature for seed germination is 18-20 degrees. Seedlings like shade and adult plants like light. They can tolerate 33 The high temperature can also survive the winter safely at minus 30 degrees. The seedlings like to be humid, especially before emergence. Because the seeds are small, if the topsoil is dry, the seeds will not be able to absorb water and cannot emerge. If it dies, too much water is not conducive to its growth. In the rainy season during the adult plant period, the soil is poor or low-lying land, and it is easy to cause root rot, resulting in the death of the whole plant.
