Embodiment Construction

[0014] The present invention will be described in further detail below by the Tibetan medicine Taoerqi winter seedling raising process done in Gannan Tibetan Autonomous Prefecture, Gansu Province.

[0015] A kind of winter seedling raising method of Tibetan medicine Taoerqi is completed according to the following steps:

[0016] (A) Selection of seeds 1) On September 2, the fully mature Taoerqi fruit grown in the forest land of Bola Township, Xiahe County, Gansu Province was collected; 2) The seeds were peeled off from the fruit, the surface mucus was washed with running water, and then dried under light.

[0017] (B) Sowing time and environment The sowing time is November 15th, and the daily average temperature of the experimental base of the Agricultural Science Institute of Gannan Tibetan Autonomous Prefecture, Gansu Province is 0.5°C (or -2°C, -1°C, 1°C, 2°C, 3°C or 4°C ), the altitude is 2863m, the annual precipitation is 600-800mm, the soil environment is sunny and r...

Abstract

Provided is a winter seedling culture technology for the Tibetan herb podophyllum hexandrum Royle. The technology includes the concrete steps of firstly, selecting seeds; secondly, determining the sowing period and the sowing environment; thirdly, soaking the complete and dry seeds with good maturity in a 5 mol / L gibberellin water solution for 24-36 h, sowing the seeds in seedling culture pots with rich humus soil, and then placing the seedling culture pots with the seeds in soil neatly, wherein two seeds are sown in each pot, and the sowing depth ranges from 3 cm to 4 cm; fourthly, performing field management on seedlings; fifthly, transplanting the seedlings, wherein the seedling culture pots are sheared to be broken after the overground parts of the podophyllum hexandrum Royle turn yellow and wither in late autumn, and podophyllum hexandrum Royle roots with soil are cultivated in soil good in light transmittance and rich in humus in a place with the altitude ranging from 2200 m to 3400 m and the annual precipitation ranging from 500 mm to 800 mm. By means of the technology, the germination rate of the seeds is larger than 96%, the germination potential is larger than 85%, the seedlings grow healthily and strongly, the root number reaches 2 or 3 in the transplanting process, and the root length reaches 18 cm.

Description

technical field [0001] The invention belongs to the technical field of raising seedlings of Tibetan medicine Taoerqi, in particular to a method for growing seedlings of Tibetan medicine Taoerqi in winter. Background technique [0002] peach seven ( Podophyllum hexandrum Royle) for Berberidaceae ( Berberidaceae ) Peach seven genus ( Sinopodophyllum ) herbaceous perennials. Mainly distributed in my country's Gansu, Qinghai, Shaanxi, Yunnan, Sichuan and Tibet. It usually grows in flat valleys at an altitude of 1500-4300m and under forests, forest edges or grass shrubs with good light transmission; it is suitable for cold and humid climates, low temperature and rainy summers, and dry and cold winters and springs. Studies have shown that the podophyllotoxin content in the rhizome of Taoerqi is the highest, reaching 2 to 10%. Modern medical research shows that podophyllotoxin is a successfully commercialized natural lignan, and its derivatives have been widely used in the t...
