Epiaedium pubescens seedling raising method

Abstract

An Epiaedium pubescens seedling raising method comprises the steps of seed selection, preparation of a sowing environment, sowing, covering of upper ground cloth, opening of the ground cloth, transplanting and the like. The selected seeds are high in quality, perforated first-layer ground cloth and seedling-raising hole trays inhibit growth of weeds, water accumulation of the seedling-raising hole trays can be prevented, the labor cost is reduced, sufficient soil nutrients can be kept for a long time, water resources can be saved through spray irrigation, damage to plants is reduced, the shading rate is controlled within the range suitable for growth of Epiaedium pubescens seedling raising method through shading nets, top matrix covering in holes can supplement fertility in the seedling raising period and is good in air permeability, the seedling raising hole trays are covered with the second layer of ground cloth with better water permeability, and the heat preservation effect is enhanced. By means of the seedling raising method, sprouting can be conducted five months earlier, so that the Epiaedium pubescens meets the transplanting requirement in advance, the Epiaedium pubescens is matched with the optimal growth time, harvesting is conducted one year earlier, and the earning effect is fast.

Description

technical field [0001] The invention relates to the planting of Chinese medicinal materials, in particular to a seedling raising method of Epimedium pilosa. Background technique [0002] Epimedium pilosa is a perennial herb of the genus Epimedium Berberidaceae, and it is one of the most widely used and oldest Chinese herbal medicines in China. Sichuan is one of the provinces with the largest planting area of ​​Epimedium pilosa. The climate in this area is mild and humid, with many mountains, high soil humidity, and a large area of ​​slightly acidic black sandy loam, which is suitable for large-scale planting. [0003] At present, due to the rapid increase in the demand for Epimedium pilosa, the wild Epimedium pilosa medicinal materials have been plundered and excavated, which has greatly reduced the wild Epimedium pilosa resources, so it is necessary to artificially plant Epimedium pilosa . The planting of Epimedium pilosa has strict requirements on air temperature, water ...

AI Technical Summary

Problems solved by technology

[0004] Seedling cultivation is the most important step in the cultivation of Epimedium pilosa. The growth time of Epimedium pilosa is from March to October. However, the original technology can only germinate in March of the second year of seedling cultivation. The obtained seedlings It can be transplanted only 10-12 months after germination, so it needs to wait until the third year to grow and harvest. The benefits are too slow, and the time and labor costs are too high.
