Embodiment 1

[0011] A bletilla striata seedling raising and standardized cultivation method, comprising the following steps:

[0012] (1) Select the land: Choose a cool, warm, humid environment, loose texture, good drainage, and fertile humus soil or sandy loam. Before planting, the selected area needs to be plowed and plowed deeply, at least 22cm deep.

[0013] (2) Apply base fertilizer: choose decomposed farmyard manure, and the amount of decomposed farmyard manure is about 0.8kg / m2.

[0014] (3) Digging furrows for whole soil: The height of the furrow is 0.25m, the width is 1.5m, and the holes are planted with a row spacing of 23cm and a plant spacing of 23cm.

[0015] (4) Seed selection and propagation: Seed selection should select seeds in uncracked fruit pods with an embryonic age of 5 months, and use basic medium to induce. The inoculated seeds were placed in a culture room with a temperature of 28°C for 1 week, and then moved to the greenhouse when the seeds germinated. The condi...

[0023] (2) Apply base fertilizer: choose decomposed farmyard manure, and the amount of decomposed farmyard manure is about 0.8kg / m2.

[0024] (3) Digging furrows for whole soil: The height of the furrow is 0.25m, the width is 1.5m, and the holes are planted with a row spacing of 35cm and a plant spacing of 24cm.

[0025] (4) Seed selection and propagation: Seed selection should select seeds in uncracked fruit pods with an embryonic age of 5 months, and use basic medium to induce. The inoculated seeds were placed in a culture room with a temperature of 28° C. for 2 weeks and then moved to the greenhouse when the seeds germinated. The con...

Abstract

The invention discloses a bletilla striata seedling-raising method and a standardized bletilla striata seedling cultivation method. According to the bletilla striata seedling-raising method and the standardized bletilla striata seedling cultivation method, seed selecting and breeding are mainly carried out by controlling sprouting times and substrate types according to biological characteristics of bletilla striata. The optimal sprouting time for seedling cultivation in the bletilla striata seedling-raising method is 30 days; and a substrate suitable for domestication and growth of the bletilla striata seedlings adopts a volume ratio as follows: 35-45% of mountain soil, 30-32% of humus, 22-24% of sawdust, and 12-14% of crushed melon seed shell. The standardized bletilla striata seedling cultivation method comprises the following steps: selecting land; applying a base fertilizer; preparing the land, and digging borders; selecting seeds, and carrying out breeding; carrying out field management; carrying out intercropping, and carrying out shielding and cold-proofing; and then, carrying out harvesting and processing. The bletilla striata seedling-raising method disclosed by the invention is capable of relatively well solving the problems of low survival rate, liable sprout tumbling and long domestication cycle; and thus, high-quality seedlings can be provided for subsequent large-scale planting. As a follow-up, the standardized bletilla striata seedling cultivation method has excellent preventing and treating effects on diseases, insects and pests; and thus, high yield, as well as high seedling quality and high bletilla striata quality, can be ensured.

Description

technical field [0001] The invention belongs to the technical field of cultivation and planting of traditional Chinese medicinal materials, and in particular relates to a bletilla striata seedling cultivation method and a standardized cultivation method. Background technique [0002] Bletilla striata belongs to Orchidaceae and belongs to the perennial herbaceous plant of terrestrial type. It is also known as Bletilla striata, Bletilla, Lianjicao, Baigen, etc. It is used as medicine with dried tubers. Hematemesis, chapped skin, sores and swelling. In recent years, with the large-scale use of decoction pieces of bletilla striata, the market demand for bletilla striata is increasing day by day. However, due to its special physiological characteristics, the growth and reproduction of Bletilla striata in the wild is far from meeting the market demand, and its exploitation is easy to destroy the wild environment, so the artificial planting technology of Bletilla striata has becom...
