A kind of cultivation method of alum root 'matcha' seedling

Abstract

The invention discloses a sweetleaf root 'matcha' seedling culture method which includes the steps: digging sweetleaf root 'matcha' stem base tissues in spring and summer, performing bacteria-free treatment, and inoculating the tissues on a multiple-shoot inducement culture medium for multiple-shoot inducement culture to obtain multiple shoots 30 days later; dividing the multiple shoots and placing the multiple shoots into a proliferation culture medium for proliferation culture with the cycle of 30 days; acquiring a certain number of multiple shoots by proliferation culture, dividing the multiple shoots into single bud seedlings, culturing the bud seedlings in a rooting culture medium for rooting induction, and forming a complete plant 25-30 days later; hardening the seedlings with a bottle cap in an environment with scattered light for 3-7 days, and then hardening the seedlings in an uncapped manner for 1-2 days; taking out test-tube seedlings after hardening, washing a root culturemedium and transplanting the seedlings into a seedling culture plug. Compared with the prior art, the sweetleaf root 'matcha' seedling culture method has the advantages that sweetleaf root 'matcha' seedlings are reproduced by a tissue culture technology, operation is simple, reproductive rate is high, the problem of too low speed of division propagation can be solved, and mass production of the sweetleaf root 'matcha' seedlings with consistent characters is realized.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and relates to a tissue culture method of a perennial color-leaved herb, in particular to a method for cultivating alum root 'Matcha' seedlings. Background technique [0002] Alumroot is a perennial herbaceous flower with colorful leaves native to Central America. In recent years, alum root has been introduced to China, and has gradually attracted attention due to its beautiful flowers and leaves, bright and rich colors. Alum root can be used as materials such as edging, clump planting, ground cover, potted plant, etc., and it continues to heat up in the flower market. Alum root is also introduced and planted in a small amount in southern regions such as Shanghai. The colorful leaf plant does not lose its leaves in winter in warm southern regions such as Shanghai. It can be used as a ground cover to supplement the lack of winter landscape color; it can also be used as a potted plant to...

AI Technical Summary

Problems solved by technology

[0003] There are many varieties of alum root, and some varieties can be sown and propagated, but the seeds germinate slowly, the emergence of seedlings is irregular or the consistency of seedlings is poor; the propagation cycle of ramets is long and the reproduction coefficient is low. Although the market demand is large, the supply of seedlings is limited, which hinders new varieties Promoted application of

'Matcha' is an alum root variety with green leaves and red flowers. It has grown well in southern regions such as Shanghai after planting observations, but the seedling breeding technology of this variety has not been reported so far.
