Cultivation method for dwarf type curcuma alismatifolia

Abstract

The invention relates to a dwarf cultivation method for flowers, in particular to a cultivation method for dwarf type curcuma alismatifolia. The method specifically comprises the following steps of: screening robust curcuma alismatifolia seed balls; planting in the open field; when growing plantlets to 10-30 cm, irrigating roots of the plantlets by using paclobutrazol with final concentration range of 100-500 mg / L; and performing the conventional daily water and fertilizer, disease and pest management until the curcuma alismatifoliav blooms. After treatment by the technical scheme, the plant height becomes short by about 10 percent, the scape becomes short by about 20-30 percent, the stem diameter is increased by about 10 percent, and the scape diameter is increased by about 15 percent. Since the scape becomes short, the overall feeling of the plant is compact, stronger richness is achieved, the ornamental value is improved; meanwhile, since the scape diameter is increased, the lodging resistance capacity is enhanced; and the dwarf type curcuma alismatifolia is suitable to be used as a potted plant and a flower border material.

Description

technical field [0001] The invention relates to a dwarf cultivation method of flowers, in particular to a cultivation method of dwarf ginger lotus. Background technique [0002] Ginger lotus (Curcuma alismaifolia) is a perennial bulbous herbaceous flower of the genus Zingiberaceae. It is native to Chiang Mai, Thailand and other places, and is mainly used as a flower for Buddhism. It is named because the pink bracts resemble lotus flowers and belong to the ginger family. Ginger lotus is a spike inflorescence, the upper bracts are pink broad oval sterile bracts, the lower part is honeycomb green bracts, containing purple and white small flowers, the flowers are gentle and graceful like lotus. At the same time, because it is native to the tropics and its flowers look like tulips, it is also known as "tropical tulips". The flowering period is from June to October. Due to its unique flower shape, bright color and long flowering period, ginger lotus has become a very popular ne...

AI Technical Summary

Problems solved by technology

Although ginger lotus has the advantages of large flowers, it also has the disadvantages of relatively slender flower stems and easy lodging, and the plant shape is relatively divergent and the leaves are drooping. There are certain deficiencies in being directly used as potted flowers and flower border materials.

However, there is no report on the dwarfing treatment technology of ginger lotus at home and abroad, so the study of its dwarfing technology has great novelty and application value
