Wabu Fritillaria is an economic crop with high medicinal value. It is a cultivated product of Fritillaria sichuanensis. Carbuncle, pulmonary carbuncle embolism. The medicinal material Chuan Fritillaria is an important medicine for relieving cough and reducing phlegm. Intractable diseases in today's society have become the main problems affecting people's health. The advantages of traditional medicine are highlighted. The market demand for Chuan Fritillaria is increasing, and the market gap is increasing year by year.

Fritillary fritillary is mainly distributed in the eastern part of the Qinghai-Tibet Plateau, and the western Sichuan plateau is its main production area. The harsh climate and extremely backward agricultural production technology in this area are the main reasons why it is difficult to scale the fritillary fritillary artificially. Wabu Fritillaria is the variety with the lowest distribution altitude in Fritillaria sichuanensis, and the distribution area of wild resources has a certain basis for agricultural production. It is the most promising variety to establish a large-scale production base of Fritillaria sichuanensis.

The five-year-old Wabu Fritillaria is not only the key year for the seed cultivation of Fritillaria, but also the last year of yield formation. If Fritillaria cannot obtain a reasonable composition and ratio of micronutrient fertilizers in this year, it will lead to a decline in the production of medicinal materials 1. The proportion of effective components in medicinal materials such as alkaloids is reduced, thereby affecting its efficacy.

Wabu Fritillaria: Wabu Fritillaria (Fritillaria unibracteata Hsiao et K.C.Hsiavar.wabuensis (S.Y.Tang et S.C.Yue) Z.D.Liu, S.Wang et S.C.Chen) is one of the source species of the medicinal material Chuan Fritillaria, and is a precious traditional Chinese medicine The wood is generally excavated after the aboveground part is completely withered from late July to early August, and the fibrous roots and silt are removed, and dried in the sun. It has the functions of clearing heat and moistening lung, resolving phlegm and relieving cough, dispelling stagnation and eliminating carbuncle. It is widely used in dry cough due to lung heat, dry cough with little phlegm, overworked cough due to yin deficiency, bloody sputum, scrofula, mastitis, lung abscess and other diseases.

Wabu Fritillaria is a perennial herb that grows slowly. In the process of seed reproduction and growth, after germination, seeds develop and mature through seedlings, vegetative growth renewal, and reproductive growth renewal in sequence. In the first year of seed sowing, only one needle-shaped leaf (commonly known as "a needle") grows, and in the second year it develops into a wider cotyledon (commonly known as "chicken tongue"). These two years are the seedlings of Fritillaria stage, the bulbs grow slowly; in the third year, the aboveground part has 1-2 wide leaves (commonly known as "one leaf"), and in the fourth year, the stems begin to pump (commonly known as "tree son"), but generally do not bloom. In the past two years, the underground bulbs grow rapidly, which is the vegetative growth and renewal stage of Fritillaria; in the fifth year, flower stems and flowers (commonly known as "lantern flowers") begin to develop and bear fruit, and undergo reproductive growth and renewal. The bulbs of Fritillaria wabu have high quality, high content of medicinal ingredients, and low growth altitude, which provides the most economical and effective variety selection for artificial cultivation of Fritillaria sichuanensis medicinal materials.

The trace element fertilizer composition provided by the invention is composed of zinc fertilizer, boron fertilizer and molybdenum fertilizer in specific parts by weight. Among them, zinc plays an important role in photosynthetic processes such as participating in chlorophyll formation, preventing chlorophyll degradation and forming carbohydrates. Zinc can participate in the activation process of certain enzymes such as glutamate dehydrogenase and alcohol dehydrogenase. And the synthesis of tryptophan also needs zinc, and tryptophan is the precursor of synthetic auxin (IAA), and auxin also plays an important role in plant crop medicine. Zinc is also a component of many enzymes, including zinc in alcohol dehydrogenase, Cu-Zn superoxide dismutase, carbonic anhydrase and RNA polymerase. Molybdenum-containing protein has nitric acid reduction and nitrogen fixation, which can improve protein quality. Molybdenum can also promote photosynthesis and remove the poisonous effect caused by the accumulation of active aluminum in crops in the soil. Molybdenum also plays a role in the absorption of iron by plants and Transportation plays an irreplaceable important role. Boron participates in the metabolism of carbohydrates in crops, in the synthesis and utilization of auxin in the body, in the nodulation and nitrogen fixation of legumes, in the formation and elongation of plant flower organs, and in the formation of plant seeds.

In summary, the trace element composition provided by the present invention participates in crop protein synthesis, enzyme activation, nitric acid reduction and nitrogen fixation, participates in the synthesis and utilization of carbohydrates and auxin in crops, and removes active aluminum in crops through synergistic effects. Toxic effects in the fritillaria, etc., the three compositions act synergistically to jointly affect the accumulation of the bulb weight of the fritillaria wabu, affect the yield of the fritillaria wabu, and also affect the content of alkaloids in the fritillaria wabu. The composition provided by the present invention is used for the cultivation of five-year-old Fritillaria wabu, so that the bulb weight gain rate of the obtained Fritillaria wabu can reach 113.75%, and compared with the Fritillaria wabu that has not been applied with trace element fertilizers, the yield per unit area is increased The rate and the weight gain rate of a single bulb reached 95.45%, and the alkaloid content (calculated as sibetine) increased by 87.12%.

Wabu fritillary is mainly distributed in Maoxian, Beichuan, Songpan, and Heishui counties in the upper mountainous area of the Minjiang River in Sichuan. It mainly grows under shrubs and small trees at an altitude of 2500-3000m.

Wabu Fritillaria was used as Chuanbeimu, which was first recorded in "Compendium of Materia Medica Supplements". It was said that "it is as big as money, with thin white skin and yellow spots, sweet taste, and longan. It is the first among Chuanbei and rare." . Wabu Fritillaria has always been valued by the local medical institutes. It is believed that its effect of clearing away heat and nourishing the lungs, reducing phlegm and relieving cough is better than that of Dark Purple Fritillaria (F.unibracteata Hsiao et K.C.Hsia), but due to early development, there are not many wild resources , the wild Wabu Fritillaria is endangered.

Existing studies have shown that there are at least 7 kinds of alkaloids in Fritillaria wabu, and the polarity of each alkaloid is not much different, but the content is quite different.
