Embodiment 1

[0095] (1) Pretreatment of bulbs: collect the bulbs withered in the aboveground part of Zezhu in Guangxi in October of that year, cut off dead roots and old roots, clean them, screen and grade them, select bulbs with a diameter of 4-6 cm, and then soak them in 800 10 times the chlorothalonil solution for 10 minutes, take it out and dry it;

[0096] (2) Refrigeration: Place the pretreated Guangxi Zedoary bulbs in a culture tray, and cover the bulbs with sterilized and moist and loose sand. Then put the culture plate into a refrigerated room with 15°C and RH of 70% for 60 days. During the refrigerated period, spray water once every morning and evening to keep the RH in the refrigerated room at 70%.

[0097] (3) Acceleration: Take Guangxi Curcuma bulbs out of the cold room, and the bulbs are still covered with sand, put them in a greenhouse at 30°C and RH≥90% for 30 days, and spray water once a day in the morning and evening during the germination period to maintain RH ≥ 90% in ...

Embodiment 2

[0101] (1) Pretreatment of bulbs: collect the bulbs of Guangxi Zedoary Curcuma with withered aerial parts in October of that year, wash off the soil, cut off fibrous roots, screen and grade, select Guangxi Curcuma Curcuma bulbs with a diameter of 4-6cm, and then soak them Put it in 800 times chlorothalonil solution for 10 minutes, take it out and dry it;

[0102] (2) Refrigeration: Place the pretreated Guangxi Zedoary bulbs in a culture tray, cover the bulbs with sterilized and moist peat soil, the degree of wetness of the peat soil can be held into a ball by hand, loosen and then disperse It is advisable; then put the culture plate into a refrigerated room at 15°C and 80% RH for 50 days, and spray water once every morning and evening during the refrigerated period to keep the RH in the refrigerated room at 80%;

[0103] (3) Acceleration: Take the bulbs out of the refrigerator, and the bulbs are still covered with peat soil, put them in a greenhouse at 30°C and RH≥90% for 30 d...

Embodiment 3

[0107] (1) Pretreatment of bulbs: collect the bulbs withered in the aboveground part of Ezhu in Guangxi in November of that year, wash off the soil, cut off the fibrous roots, screen and grade, select bulbs with a diameter of 3 to 4 cm, and then soak them in 800 10 times the chlorothalonil solution for 10 minutes, take it out and dry it;

[0108] (2) Refrigeration: Put the pretreated Guangxi Zedoary bulb culture tray above, and cover the bulb with sterilized and moist perlite. The degree of wetness of the perlite should be held into a ball, loosen and disperse. ;Then put the culture plate into a refrigerated room with 15°C and RH of 90% for 40 days, and spray water once every morning and evening during the refrigerated period to keep the RH in the refrigerated room as 90%;

[0109] (3) Acceleration: Take the bulbs out of the cold room, the bulbs are still covered with perlite, put them in a greenhouse at 30°C and RH≥90% for 30 days, and spray water once a day in the morning an...

Abstract

The invention discloses a Guangxi zedoary aquiculturing and blooming method. The method comprises the following steps: (1), seedball pretreatment: collecting, screening, grading, cleaning and sterilizing Guangxi zedoary seedballs; (2), refrigeration: refrigerating the Guangxi zedoary seedballs in a refrigerator with the relative humidity (RD) 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 RD being larger than or equal to 90 percent at 25 DEG C to 30 DEG C for germination for 10 days to 30 days; (4), blossom bud culture: putting the germinated seedballs in a culture chamber with the temperature of 25-32 DEG C, the RD of 70 percent to 90 percent and the illumination intensity of 45 micromol m<-2> s<-1> for aquiculture until bud bodies swell, and mauve inflorescences occur in green bracts but are not exposed; and (5), aquiculture and blossom: putting the seedballs treated by the step (4) in natural conditions for aquiculture until bloom. The invention realizes the aquiculture and the blossom of Guangxi zedoary which is originally only suitable for planting and blooming in soil culture and pot culture modes so that the Guangxi zedoary becomes an aquiculture flower.

Description

technical field [0001] The invention relates to a method for plant hydroponics, in particular to a method for hydroponic flowering 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 growth of Curcuma in Guangxi requires sufficient sunlight and is not resistant to water and humidity. It likes loam rich in organic matter, loose and fertile, strong in water retention and fertility, and well drained. The soil is best in neutral to slightly acidic. 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. The flowering period of Curcuma in Guangxi under natura...
