Embodiment 1

[0094](1) Collect the withered bulbs of the above-ground part of Ezhu in Guangxi in October of that year, cut off the dead roots and old roots, clean them, screen and grade them, select bulbs with a diameter of 4-6cm, and then soak them in 800 times chlorothalonil In the solution for 10 minutes, take it out to dry and store;

[0095] (2) Put the Guangxi Zedoary seed bulbs in the culture tray, and cover the bulbs with sterilized, moist and loose sand. Refrigerate in a refrigerator at 15°C and RH of 70% for 60 days. During the refrigeration period, spray water once a day in the morning and evening to keep the RH in the refrigerator at 70%;

[0096] (3) Take the Guangxi Zedoary bulbs out of the cold room, the bulbs are still covered with sand, and put them in a greenhouse at 30°C and RH≥90% for germination for 30 days. During the germination period, spray water once a day in the morning and evening to keep the temperature in the greenhouse RH≥90%;

[0097] (4) Place the bulbs a...

Abstract

The invention discloses a Guangxi zedoary florescence control method which comprises the following steps: (1), seedball treatment: collecting, screening, grading, cleaning, sterilizing and then airing Guangxi zedoary seedballs; (2), refrigeration: refrigerating the Guangxi zedoary seedballs in a refrigerator with the relative humidity of 70 percent to 95 percent at 13 DEG C to 20 DEG C for 30 days to 60 days; (3), germination: taking the seedballs out of the refrigerator and putting the seedballs into a greenhouse with the relative humidity larger than or equal to 90 percent at 25 DEG C to 30 DEG C for germination for 10 days to 30 days; and (4), flower culture: putting the germinated seedballs in a culture chamber for culture until bud bodies swell, and placing seedballs capable of forming blossom buds in natural conditions for culture when mauve inflorescences occur in green bracts but are not exposed. The method enables Guangxi zedoary which originally blooms between April and June and between July to September to bloom and fully bloom during the Spring Festival, thereby achieving the aim of controlling the florescence of the Guangxi zedoary and providing a high-grade new-year flower for the Spring Festival.

Description

technical field [0001] The invention relates to a method for regulating the flowering period of plants, in particular to a method for regulating the flowering period of Zedoary zedoary in Guangxi. Background technique [0002] Curcuma kwangsiensis (Curcuma kwangsiensis) is a perennial herb of the genus Curcuma in the family Zingberaceae, also known as Curcuma and Curcuma. It is a subtropical bulbous flower that is cultivated or wild in South China. The plant height of Curcuma zedoary in Guangxi is 0.5-1.1m. Spikes are extracted from the rhizome in spring or from the leaf sheath in autumn. Flower resources also meet the new flower plants defined by the International Horticultural Society. However, most of the current researches on Curcuma in Guangxi are its medicinal value, and there are few studies on it as an ornamental flower. There is only a report that South China Botanical Garden has screened Curcuma curcuma from Guangxi Curcuma. [0003] Since Guangxi Curcuma mainly ...
