Iphigenia indica kunth et benth seed grow seedling method

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...

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 difficult to break the dormancy under natural conditions, and the seed shell is hard and poor in permeability. In addition, Lijiang Arrowhead Mushroom is also a light-loving and warm-loving plant. Very strict requirements

The emergence time of seeds under natural conditions is as long as 2-3 months, and the emergence rate is less than 20%, which increases the production cost
