Efficient Bletilla striata seed propagation technology

Abstract

The invention discloses an efficient Bletilla striata seed propagation technology. The efficient Bletilla striata seed propagation technology mainly includes the steps of firstly, preparing tools which include an ultraviolet sterilizing box, a seed soaking jar, a cultivation jar, filter cloth, a ceramic plate, fine sand and a spoon, and sterilizing the tools for standby; secondly, taking an iodinetincture with the concentration being 1.2%, sterilizing Bletilla striata seeds in the iodine tincture for 2-3 minutes, fishing out, cleaning with cold boiled water, and naturally drying; thirdly, sterilizing the dried Bletilla striata seeds with ultraviolet for 10-12 minutes, and taking out; fourthly, adding cleaning water into the seed soaking jar, adding 2% of sucrose, 0.9% of NaCl and 20% of potato juice, performing high-temperature sterilizing, and cooling to 28-30 DEG C; fifthly, wrapping the sterilized Bletilla striata seeds with the filter cloth, soaking the filter cloth containing theBletilla striata seeds into the seed soaking jar for 1-2 hours, and then placing the soaked filter cloth containing the Bletilla striata seeds into the cultivation jar to perform germination acceleration for 3-4 days at 30-33 DEG C; sixthly, flatly laying the sand after high-temperature sterilization on a floor in a sterile room, spreading the Bletilla striata seeds after the germination acceleration on the sand, spreading a layer of sand 0.5cm in thickness on the surfaces of the seeds, slightly compacting, and spraying a 0.5% urea sterilizing solution until water content is 30%.

Description

technical field [0001] The invention relates to a breeding technology, in particular to the breeding technology of the traditional Chinese medicine bletilla striata, and belongs to the field of agricultural technology. Background technique [0002] Bletilla striata, (scientific name: Bletilla striata) is also known as Lianjicao, Gangen, Baigi, Ruolan, Zhulan, Zilan, Zihui, Baili, Ground Screw, Baijiwa, Baigen, and Chowjiaoqi. Perennial herbaceous bulbous plants (root tubers), plant height 18-60 cm. Mainly distributed in China, Japan and northern Myanmar. The main flowering period is in spring, but depending on the climate of various places, it may bloom from late winter to early summer. Bletilla striata has a wide range of medicinal value and garden value. Mainly used for astringent hemostasis, detumescence and granulation promoting. The flowers have purple, white, blue, yellow and pink colors, and can be potted indoors for viewing, or decorated in a relatively shaded fl...

AI Technical Summary

Problems solved by technology

Before the new leaves germinate in spring or after the aboveground part withers in autumn and winter, dig up the old plants and divide the pseudobulbs for division. Each plant can be divided into 3-5 plants with terminal buds. Traditional cultivation mainly relies on division. However, the propagation cycle of ramets is long, the propagation efficiency is low, and the consumption of seeds is large, so it is difficult to meet the needs of mass cultivation.
