Division propagation method of Bletilla striata

Abstract

The invention relates to a division propagation method of Bletilla striata, characterized by comprising the steps of I, selecting a planting land, to be specific, selecting a planting land with blacksandy soil and humus soil; II, cultivating, to be specific, thoroughly clearing surface weeds, applying quick lime 100 kg / mu during plowing, and performing fine tilling; III, propagating, to be specific, digging out seed bearers of Bletilla striata, using a blade to divide buds, and coating the buds with plant ash for planting; IV, digging ditches 20-25 cm in spacing and 5-6 cm in depth, and placing divisions according to the spacing of 10-12 cm; V, after planting, spraying acetochlor, sealing, and clearing weeds after seedlings of Bletilla striata emerge evenly; VI, spraying once, monopotassium phosphate or diluted human-livestock manure in the early stage of planting; VII, paying attention to observation and to irrigation or drainage, keeping constant moisture, and avoiding flooding; VIII, preventing pest damage from cutworm and wireworm, and stopping application of pesticides two months before harvesting.

Description

technical field [0001] The invention relates to a planting technique, in particular to the planting technique 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 flow...

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.
