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.

Embodiment 1

[0026] Divide the different growth periods of ginger root into 4 stages, that is, stage 1 from the beginning of germination to budding of the bulb, stage 2 from budding to the full expansion of the first true leaf; and stage 2 from the first true leaf to the third true leaf Stage 3 is when the true leaves are fully expanded; stage 4 is from the 3rd true leaf to flowering. Among them, stage 1 is all dark treatment. The rest of the embodiments are consistent with this division.

[0027] Step 1. Preservation, screening and processing of bulbs: Store the bulbs propagated in the previous year at 12°C. Then select strong bulbs for processing, requiring large cue bulbs (Chiang Mai flour, Dutch red bulbs with a diameter of more than 1.5cm, and Dutch red bulbs with a diameter of more than 1cm), more seed bulbs, and more than 50% with a final concentration of 0.2%. Soak the fungazine wettable powder solution for 30 minutes and dry it in air; soak it with 2000 times 15% mite cleaning c...

Embodiment 2

[0031] Step 1. Same as Step 1 in Example 1.

[0032] Step 2. Same as Step 2 of Example 1.

[0033] Step 3. Seedling cultivation and flowering: transfer the germinated bulbs together with the substrate to an environment at 32°C, and supplement light according to different developmental stages, that is, at stage 2, light at 8000lux for 12 hours; at stage 3, 14 hours The light intensity of 10000lux is supplemented; at stage 4, the light intensity of 12000lux is supplemented for 18 hours, and the conventional water and fertilizer management is carried out. Chiangmai powder began to bloom 43 days after budding, with an average age of 5 leaves; Red Guanyin began to bloom 43 days after budding, with an average age of 5 leaves; Holland Red began to bloom 42 days after budding, with an average age of leaves 5.5 tablets.

Embodiment 3

[0035] Step 1. Same as Step 1 in Example 1.

[0036] Step 2. The germination time is September 20th of the lunar calendar, and all the other are with step 2 of embodiment 1.

[0037] Step 3. Seedling cultivation and flowering: transfer the germinated bulbs together with the substrate to an environment at 35°C, and supplement light according to different development stages, that is, at stage 2, 12 hours of light intensity of 8000lux; at stage 3, 16 hours The light intensity of 10000lux is supplemented; at stage 4, the light intensity of 12000lux is supplemented for 20 hours, and the conventional water and fertilizer management is carried out. Chiangmai powder began to bloom 43 days after budding, with an average age of 6 leaves; Red Guanyin began to bloom 39 days after budding, with an average age of 5 leaves; Holland Red began to bloom 43 days after budding, with an average age of leaves 6 slices.

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...
