Method for cultivating amomum villosum

Abstract

The invention discloses a method for cultivating amomum villosum, including the following steps: Amomum longiligulare T.L.Wu is taken as male parent, and amomum villosum farming cultivation type long fruit No. 2 is taken as female parent; the flower of female parent is protected by bagging in bud pregnant period, and manual emasculation is carried out in blooming period; pollen of male parent is scraped to be pollenized into stigma of the flower of treated female parent, and the flower of female parent is protected by bagging again; after hybridization of female parent, other undeveloped flowers of the inflorescence are removed; when hybridized flower forms a young fruit, a bag protector is removed, and management is reinforced until harvest, thus obtaining hybridized generation F1; seeding, continuous selfing, directional seed selection and cultivation are carried out on the hybridized generation F1 by taking disease resistance, stress resistance, late blooming and high natural maturing rate as seed selection aims, thus obtaining the required amomum villosum. The cultivation method of the invention has simple process and easy control, and amomum villosum new breed having the advantages of disease resistance, stress resistance, late blooming and high maturing rate can be obtained by optimal control on seed selection factors.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to the cultivation of medicinal plants, and in particular to a method for cultivating Cinnamomum chinensis. Background technique [0002] Amomum Villosum Lour is the mature fruit of Amomum Villosum Lour, a plant of the ginger family, and is one of the four major southern medicines in my country. The taste is pungent and warm, and returns to the three meridians of spleen, stomach and kidney. It has the effects of promoting qi and neutralizing, harmonizing the stomach and refreshing the spleen, astringent and antidiarrheal, regulating qi and preventing miscarriage, fragrant and damp, widening the chest and invigorating the stomach. Its medicinal value is very high . [0003] The main production area of ​​Yangchun sand is in Panlong Jinhuakeng, Panlong Town, in the eastern suburb of Yangchun City, Guangdong Province. The cultivation history has been as long as 600 years. Ov...

Problems solved by technology

[0006] Among the four Yangchunsha farm cultivation types, Changguo No. 1 has relatively large fruit. Although the quality is good, it is an early flowering type with poor pollen development. It often misses insect pollination and is not conducive to artificial pollination, so the pollination rate is not high. , affect the fruit setting rate, so Changguo 1 is often low-yielding, and the germplasm has poor disease resistance and stress resistance, and the plant seedlings are weak and unfavorable for reproduction, so they are gradually eliminated by nature or artificially; Yuanguo 1 is also an early flowering type, and its early The pollen development status at flowering time is similar to that of Changguo No. 1, so the pollen development is poor, which is unfavorable for pollination, and often misses the opportunity of insect pollination and artificial pollination. The fruit setting rate and yield are low, and the germplasm has poor disease resistance and stress resistance. Artificially eliminated; Yuanguo No. 2, the stigma is high and difficult to pollinate, the pollination situation is similar to Changguo No. 1, the fruit set rate and yield are also low, and it is gradually eliminated by nature or artificially; Changguo No. 2, the fruit grows up and is plump , flowering is relatively late, which is more conducive to the pollination of ribbon bees, so the pollination rate and fruit setting rate of Changguo 2 are the highest. The germplasm has strong disease resistance and stress resistance. It is the main cultivation type with the widest distribution in Yangchun Dao production area at present, but this variety still cannot completely solve the artificial pollination problem of Amomum planting in Yangchun Dao production area, and it is difficult to mobilize the enthusiasm of local farmers for planting

[0007] At present, the method of obtaining high-quality seeds by means of multi-stage selection, although the Changguo No. 2 plants with high seed setting rate, disease resistance, strong stress resistance, good quality and high yield are screened out, new varieties can be obtained by this method. The production operation cycle is long
