Embodiment 1

[0025] Embodiment 1: the gathering and storage of seed

[0026] In the first ten days of September, the fully mature Taoerqi fruits at an altitude of 2,300 meters above Xinglong Mountain in Lanzhou City were harvested. After washing, they were stored in wet sand in an incubator. The incubator was kept at a temperature of 10°C for 12 hours and a temperature of 3°C for 12 hours a day. The sand used for storage is acidic coarse river sand with a water content of about 30%, that is, it is advisable to knead it into a ball without dripping water. Store until the beginning of spring in early February of the following year and take out the seeds to accelerate germination.

Embodiment 2

[0027] Embodiment 2: the germination of seed

[0028] After taking out the stored seeds, use 23% salt water to select seeds, remove the seeds floating in the upper part of the salt solution, and soak the remaining seeds in 0.5% potassium permanganate at room temperature for 2 hours for surface disinfection. After disinfection, use a concentration of Soak 80mg / L GA4+7 at room temperature for 48 hours, dry or wipe off the moisture on the surface of the seeds, and place them in an artificial climate box at 16°C with an air humidity of 95% to germinate. If it is below 1cm, it will be planted in the plug tray of the red light-transforming film greenhouse.

Embodiment 3

[0029] Example 3: Sowing in plug trays in greenhouses with red light conversion film

[0030] Cultivation of plug seedlings was carried out in a single-sided wall greenhouse at the Biological Garden Base (1700 meters above sea level) in Heping Town, Yuzhong County. After mid-February, under the condition of covering quilts or straw curtains at night, the minimum temperature in the greenhouse at night can be kept above 8°C. A 50-hole plastic hole tray was used to raise seedlings, filled with 1000 times liquid 50% carbendazim wettable powder sterilized mixed matrix (peat soil: perlite: vermiculite = 3:1:1), 1 hole per hole Seeds, 3cm deep, routinely managed after sowing until emergence. In about 30 days, more than 95% of the seeds broke through the soil and unfolded the cotyledons. The seedlings are strong and the cotyledons are dark green, and then the subsequent treatment is carried out.

[0031] Through the two steps of germination of seeds and sowing in plug trays in green...

Abstract

The invention discloses an imitative-ecological podophyllum hexandrum seedling raising method, belongs to the field of ecological planting of medicinal plants and aims at solving the problems of low seedling raising rate, slow seedling growth, long seedling raising period, high cost and incidence rate increase of root rot, damping off and other diseases at a seedling stage of an existing method. The method comprises the steps of seed harvesting and storage, seed germination accelerating, sowing in a greenhouse holed tray, young seedling growth promotion and prevention and control of the diseases at the seedling stage, early sowing, planting and transplantation of podophyllum hexandrum holed-tray seedlings and culture and harvesting of high-quality podophyllum hexandrum seedlings. By adopting the imitative-ecological podophyllum hexandrum seedling raising method, the most suitable environment and nutrition conditions are created at different growth and development stages, the physiological conditions of the seedlings are improved, the seedling raising rate of the method is improved, seedling raising time is shortened, high-quality strong seedlings are cultured, further the reviving rate in a next year is improved, growth and development of the seedlings are promoted, the incidence rate is reduced, the cost is reduced, and the productivity is improved through intensive measures to achieve the best seedling raising effect.

Description

technical field [0001] The invention belongs to the field of ecological planting of medicinal plants, and in particular relates to a method for cultivating high-quality seedlings of Taoerqi. Background technique [0002] peach seven ( Sinopodophyllum hexandrum Royle ) is the seventh genus of Berberidaceae, a national third-level protected plant, mainly distributed in Shaanxi, Gansu, Qinghai, Tibet, Sichuan, Yunnan, Ningxia and other provinces in China. In the distribution area, Taoerqi often appears in the valley forests, bushes, and rock crevices with secondary vegetation or complex terrain with good light transmission at an altitude of 1500-3400m, and rarely appears in virgin forests. It is also rarely found in open grasslands. Podophyllotoxin, the main medicinal ingredient in its roots and rhizomes, is the precursor for the synthesis of anticancer drugs GP7, VP-16, VM-26, NK611, etc. With the characteristics of fast onset of action, high cure rate, and good safety, it h...
