Method for cultivating Lunar New Year Curcuma alismatifolia Gagnep

Abstract

The invention provides a method for cultivating Lunar New Year Curcuma alismatifolia Gagnep. The method comprises the following steps: (1) screening seed bulbs: screening robust seed bulbs from seed bulbs propagated last year; (2) accelerating germination of the seed bulbs: accelerating germination of the seed bulbs screened in the step (1) in an environment of 30-35 DEG C from September 20 to October 5 in lunar calendar, burying the seed bulbs in a substrate having moisture retaining capacity, and accelerating germination for 30-40 days till buds can be exposed out of soil; and (3) growing seedlings and blooming: transferring the seed bulbs germinating in the step (2) into the environment of 30-35 DEG C together with the substrate, and supplementing light according to different development stages, wherein light with the light intensity of 6,000-8,000lux is supplemented for 12 hours from germination to full expansion of a first true leaf; light with the light intensity of 8,000-10,000lux is supplemented for 14-16 hours from full expansion of the first true leaf to full expansion of a third true leaf; light with the light intensity of 10,000-12,000lux is supplemented for 16-20 hours from full expansion of the third true leaf to blooming; conventional water and fertilizer management is performed; a blooming stage can be entered 40-45 days later; and the leaf age is 5-6 leaves. Through adoption of the method, the blank of domestic use of the Curcuma alismatifolia Gagnep on Spring Festival is filled up.

Description

technical field [0001] The invention discloses a technical process for cultivating New Year's Eve ginger lotus, which belongs to the technical field of plant cultivation and breeding. Background technique [0002] Ginger lotus (Curcuma alismaifolia Gagnep) is an internationally popular flower species of the genus Curcuma Linnaeus. It is a perennial bulbous herbaceous flower. It is native to Chiang Mai, Thailand and other places. It is mainly used as a flower for Buddhism. Because the bracts resemble lotus and belong to Zingiberaceae, it is called ginger lotus. Ginger lotus is a spike inflorescence, the upper bracts are pink, red, white broad oval sterile bracts (the color of the bracts varies according to the variety), and the lower part is honeycomb green bracts, containing purple and white florets. There is a certain amount of planting in southern my country such as Guangdong, Fujian, Yunnan and Hangzhou, and the market prospect is extremely promising. [0003] Ginger lo...

Problems solved by technology

At the same time, in addition to the light time, the light intensity is also the key to the flowering of ginger lotus. According to the applicant's years of research experience, the light intensity of general greenhouses is too weak to meet the needs of ginger lotus.

In addition, since the ginger lotus itself is a tropical plant, heating in winter should be a necessary requirement for its growth, but under artificial control conditions, the optimal temperature still needs to be carefully explored and determined through trial and error.
