Problems solved by technology

In recent years, there has been artificial cultivation in Lijiang City, Yunnan Province, mainly by excavating the underground bulbs of wild Lijiang Arrowhead mushrooms for planting. Since 95% of Lijiang Arrowhead bulbs have the characteristic of alternate growth, the bulb sowing yield is low
Seed is the best propagation material, but the seed dormancy period is long, it is d

Embodiment Construction

[0012] 1. Seed treatment

[0013] The local wild Iphigenia indica Kunth (Iphigenia indica Kunth) in Shigu, Lijiang is selected as the provenance. The wild Iphigenia indica Kunth here has strong stress resistance and high content of colchicine. Seeds are collected from four-year-old and above fine and healthy plants in the first year, and the thousand-grain weight is greater than 2.2g. In order to break the seed dormancy, remove the impurities from the seeds collected that year, wrap them in kraft paper and store them in a refrigerator at 2-5°C for 5-6 months, turning them once a week during the storage period. Because the seed shells of Arrowhead mushroom seeds in Lijiang are hard and have poor permeability, the seeds stored at low temperature are soaked in water with pH=6-7 for 18-24 hours to soften the seed shells. Lijiang Arrowhead Mushroom is a kind of light-loving and temperature-loving plant. It cannot germinate under dark and low temperature conditions. Therefore, it i...

Abstract

The present invention provides a seedling-cultivating method of Iphigenia indica Kunth seed. It is characterized by that said method includes the following steps: (1, storing the seed for 5-6 months at 2-5deg.C, soaking the seed for 18-24hr in whater whose pH value is 6-7, then under the condition of that temperature is 25-28deg.C, illumination is 2000-3000lx and illumination time is 10-12hr every day accelerating germination; (2), uniformly mixing the treated seed and humectous soil according to the volume ratio of 1:3, then scattering, after scattering covering with fine soil layer whose thickness is 1-2min, then covering with a layer of loose hair whose thickness is 2-3cm, promptly spraying water and building plastic hot house; and (3), retaining soil humidity for two months before cultivating seedling, making the soil humidity be 80-85% and making its temperature be 15-30deg.C. Said invention can make the emergence time be shortened to 40-50 days and the rate of emergence can be up to above 95%.

Description

technical field [0001] The invention relates to a seedling raising method of Lijiang Arrowhead mushroom seeds. Background technique [0002] Iphigenia indica Kunth is a small perennial herb of Liliaceae, distributed in Tibet, Sichuan, central and northwestern Yunnan. The bulb is used as medicine, mainly for the treatment of gout and tumor. Lijiang Arrowhead Mushroom is the main source of medicinal materials for extracting, separating and preparing colchicine and its analogues in China. With the continuous expansion of the market demand for colchicine, wild Arrowhead Mushrooms in Lijiang have been destructively excavated and are on the verge of extinction . In recent years, there has been artificial cultivation in Lijiang City, Yunnan Province, mainly by digging the underground bulbs of wild Lijiang Arrowhead mushrooms for planting. Since 95% of Lijiang Arrowhead bulbs have the characteristic of alternate growth, the bulb sowing yield is low. Seed is the best propagation m...
