Embodiment 1

[0028] 1. Field selection and arrangement

[0029] Choose a field with an annual average temperature above 14°C and a convenient water source to build a plastic greenhouse, plow the land in the greenhouse until the upper part is virtual and the lower part is solid, and it is flat to no rubbish. Tiling a substrate with a thickness of 8 cm, the substrate is a mixture of sterilized river sand, plant ash, potassium permanganate, and diamine compound fertilizer in a volume ratio of 200:40:1:4.

[0030] 2. Treatment of white and corm

[0031] Select the white bulbs with a growth period of 1 to 2 years, full and round bulbs and well-developed roots as the bulbs, keep the root length of the bulbs at 3 to 5 cm, and separate them along the connecting parts according to the growth line of the bulbs. Soak a single small corm in 0.1% potassium permanganate aqueous solution for 1 hour, then rinse with tap water, at 1.0×10 -6 mol / L naphthaleneacetic acid aqueous solution for 4 hours, take ...

Abstract

The invention discloses a Bletilla striata germination accelerating method. The method comprises the steps of cutting a Bletilla striata corm into single cormlets along a growth line connecting part, soaking with a potassium permanganate aqueous solution and a naphthylacetic acid aqueous solution sequentially, lightly pressing the treated single cormlets into a substrate upwards along the bud scar, controlling the temperature and the relative humidity of a plastic greenhouse and carrying out field and budding management to promote growth of Bletilla striata buds, cutting the Bletilla striata corm according to interval of 1-2 buds everyday when 4-5 buds grow at the top end of the Bletilla striata corm, and then planting. The method is simple and easy, has low cost, solves the problem of low budding coefficient when the Bletilla striata corm is used as a seed, can promote the Bletilla striata corm to generate more buds, improves the budding coefficient of the Bletilla striata, effectively relieves the phenomenon of Bletilla striata provenance shortage, is suitable for Bletilla striata buds in a wide planting region, can meet large-area and large-scale germination accelerating requirements and has double meanings in production and economics.

Description

technical field [0001] The invention belongs to the technical field of artificial planting of medicinal plants, and in particular relates to a method for accelerating germination of the endangered medicinal plant Baiji. Background technique [0002] Bletilla striata (Bletilla striata) is a perennial herbaceous plant belonging to the family Orchidaceae. It is a national second-class endangered plant. It is also known as Bletilla striata and Purple Orchid. It is mainly distributed in Guizhou, Hubei, and southern Shaanxi in the south of the Qinling Mountains in my country. Generally, it grows under the evergreen broad-leaved forest at an altitude of 100-3200 meters, in the grass on the roadside or in the crevices of rocks. [0003] There are four species of plants in the genus Baiji included in "Flora of China", namely Huabaiji, Xiaobaiji, Baiji and Huanghuabaji, all of which can be used as medicine, and my country is the main production area. White and dried tubers are used f...
