Problems solved by technology

[0004] However, because there are relatively few varieties of Fritillaria fritillata, narrow-leaf varieties, broad-leaf varieties (also known as Yubei) and multi-seeded varieties are mainly used in current production. During the production process in recent years, it has been found that the variety degradation phenomenon is relatively serious. It is mainly manifested in the characteristics of unstable growth potential, commodity quality, and decreased disease resistance, which have seriously affected the healthy development of the fritillaria industry.

Embodiment 1 to Embodiment 6

[0019] In 2010, a group of 200 bulbs was irradiated at a dose rate of 2Gy / Min, and the radiation doses were 0, 10, 20, 30, 40, and 60Gy, and the irradiated bulbs (M 0 Generation) According to the conventional planting method of Fritillaria fritillaria, 12 seeds per row, with a spacing of 5 cm between seeds and a row spacing of 15-20 cm, were planted in the experimental base of Zhangshui Town, Yinzhou District, the main production area of ​​Fritillaria fritillaria, and the emergence rate, plant height and absolute The results are shown in Table 1.

[0021]

[0022] As can be seen from Table 1, different radiation doses will adversely affect the emergence rate, growth and yield (bulb size and reproduction coefficient, etc.) of Fritillaria fritillaria bulbs. According to the comprehensive performance of the irradiated offspring, it is advisable to choose 20Gy treatment.

Abstract

The invention relates to a cultivation method of high-yield heat-resisting fritillaria thunbergii germplasms. The cultivation method is characterized by comprising the steps of a) selecting the fritillaria thunbergii bulbs just beginning dormant and controlling each bulb in the range of 22-33g, b) performing irradiation treatment by use of 137Cs by the dosage of 10-20Gy per 180-220 bulbs and at the dosage rate of 2Gy / Min, and c) planting the fritillaria thunbergii bulbs previously treated by irradiation by use of a conventional method and screening out the high-yield heat-resisting fritillaria thunbergii by the sprout tumble stage and the yield of the bulbs as assessment indexes. Compared with a traditional hybridization technique, the radiation induced mutation technique adopted in the cultivation method of the high-yield heat-resisting fritillaria thunbergii germplasm is capable of shortening the breeding period of new species of the fritillaria thunbergii, and the obtained new germplasms of the fritillaria thunbergii are capable of effectively delaying the sprout tumble stage, and are far higher than conventional species in propagation coefficient and absolute yield, and the difference is remarkable.

Description

technical field [0001] The invention relates to the field of new germplasm cultivation, in particular to a method for cultivating the high-yield and heat-resistant new germplasm of the medicinal plant Fritillaria japonicus. Background technique [0002] Fritillaria thunbergii Mi (Fritillaria thunbergii Mi, also known as elephant shellfish and pearl shellfish, belongs to Liliaceae). Fritillaria is a perennial herb. The main ingredients are Zhebeisu, Fritillaria B, Fritillaria Xin, Beimufen, Fritillaria, and Zhebeimu II, etc. The dried bulbs are used as medicine. Fritillaria fritillaria, as a rare Chinese herbal medicine, has high medicinal value. According to the "Compendium of Materia Medica", Fritillaria is slightly cold in nature and sweet and bitter in taste. It is mainly used to treat typhoid fever, cough and qi, soothe the five internal organs, benefit the bone marrow, eliminate phlegm, moisten the heart and lungs, reduce inflammation and swelling, and treat carbuncle...
