Embodiment 1

[0036] (1) Hydroponic flowering:

[0037] Guangxi Curcuma kwangsiensis (Curcuma kwangsiensis var. In Zhongcun Farm, Panyu, Guangzhou City. The rhizomes of the parents are placed in the cultivation room, and the hydroponic culture is carried out for 20-25 days, and inflorescences grow on the rhizomes. The hydroponic conditions are: improved Hoagland nutrient solution, the height of the hydroponic liquid level is 1 / 3-2 / 3 of the rhizome, 30±1°C, relative humidity 70-80%, light intensity 3000Lux, light cycle 12 hours / days.

[0038] The composition of the improved Hoagland nutrient solution is: add 50mg of γ-aminobutyric acid and 20mg of glutathione to each liter of Hoagland nutrient solution, and mix well.

[0039] (2) Detasseling and stigma treatment

[0040] When the florets are open, cut off the anthers of the female parent with scissors to emasculate, and apply a stigma stimulating liquid on the stigma of the female parent with a brush.

[0041] The stigma stimulating sol...

Embodiment 2

[0046] (1) Hydroponic flowering:

[0047]Nanling Zezhu (Curcuma kwangsiensis var.nanglingensis) is used as the female parent, which is characterized by short and compact plant type and strong clustering, and Guangxi Curcuma kwangsiensis (Curcuma kwangsiensis) is used as the male parent, which is characterized by strong resistance and fruiting ability. In Zhongcun Farm, Panyu, Guangzhou City. The rhizomes of the parents are placed in the cultivation room, and the hydroponic culture is carried out for 20-25 days, and inflorescences grow on the rhizomes. The hydroponic conditions are: improved Hoagland nutrient solution, the height of the hydroponic liquid level is 1 / 3-2 / 3 of the rhizome, 30±1°C, relative humidity 70-80%, light intensity 3000Lux, light cycle 12 hours / days.

[0048] The composition of the improved Hoagland nutrient solution is: add 50mg of γ-aminobutyric acid and 25mg of glutathione to each liter of Hoagland nutrient solution, and mix well.

Embodiment 3

[0056] (1) Hydroponic flowering:

[0057] Curcuma kwangsiensis 'Manao' is used as the female parent, which is characterized by strong resistance and fruiting ability, and Curcuma kwangsiensis 'Manao' is used as the male parent, which is characterized by high yields of rhizomes and tubers, all planted in Guangzhou Zhongcun Farm in Panyu City. The rhizomes of the parents are placed in the cultivation room, and the hydroponic culture is carried out for 20-25 days, and inflorescences grow on the rhizomes. The hydroponic conditions are: improved Hoagland's nutrient solution, the height of the hydroponic liquid level is 1 / 3-2 / 3 of the rhizome, 30±1°C, relative humidity 70-80%, light intensity 3000Lux, light cycle 12 hours / day.

[0058] The composition of the improved Hoagland nutrient solution is: add 75mg of γ-aminobutyric acid and 20mg of glutathione to each liter of Hoagland nutrient solution, and mix well.

Abstract

The invention discloses a hybridizing method for curcuma kwangsiensis. The method comprises the steps of aquaculture blooming, detasseling and stigma treatment, and pollen treatment and pollination. According to the method, an aquaculture hybridizing method for the curcuma kwangsiensis is originated, land resources are saved, and the space utilization ratio is increased; the problem that field hybridizing is restricted to a blooming period is solved; and a prepared aquaculture nutrient solution can be used for shortening a fruit development period and increasing setting percentage, and a stigma stimulating solution can be used for prolonging pollination time of stigmas. The method provides a technical foundation for hybridized breeding of the curcuma kwangsiensis, has a significant significance in enriching germ plasm resources of the curcuma kwangsiensis and provides a reference significance in originating aquaculture hybridization technologies for other Ginger-family plants.

Description

Technical field: [0001] The invention belongs to the field of plant hybridization and breeding, and in particular relates to a hybridization method of curcuma zedoary in Guangxi. Background technique: [0002] Curcuma kwangsiensis is a perennial herb of the Zingiberaceae genus Curcuma longa. It is distributed in Guangxi, Guangdong, Yunnan and other places in my country. It is a multi-purpose plant resource integrating medicinal and ornamental values. The plant height is about 0.5m, with well-developed underground rhizomes, elliptic-lanceolate leaves, cylindrical spikes, dense bracts on the top, light green basal bracts, purple-red upper bracts, flowering period 4- September. The rhizome and expanded tuber of Zedoary zedoary in Guangxi can be used for medicinal purposes. Its rhizome is a kind of traditional Chinese medicine Zezhu, and it is one of the authentic medicinal materials in Guangxi. The effect of (Zeng Songjun et al., 2003). Guangxi Curcuma has high ornamental va...
