Background

Lily is a multifunctional economic plant integrating ornamental, edible and medicinal functions. The lily can be further divided into three types of edible lily, medicinal lily and ornamental lily according to the main application value. In recent years, with the improvement of living standard of people, the pursuit of health food is gradually upgraded, and medicinal and edible lily is mixed together to form medicinal and edible lily. The medicinal and edible lily mainly comprises Lanzhou lily (Lilium davidi var unicolor cotton), Lilium crispum (medicinal lily) (L.lancifolium) and Lilium Brownii (L.brownnii), which belong to perennial bulb herbaceous plants of Lilium (Liliacea) and Lilium of Liliaceae, and are formed by cohesion of dozens of fleshy scales.

Lanzhou lily is mainly distributed in the cold and dry mountainous areas in northwest, the Lilium tigrinum is mainly distributed in the areas of Jiangsu Yixing, Chongqing Qianjiang, Zhejiang and Guizhou, and the Longya lily is mainly distributed in the areas of Hunan, Jiangxi and Hubei. The Lanzhou lily has high sugar content, less crude fiber and fine and smooth meat quality, is a vegetable with higher nutritional and health-care values, and also has the medicinal values of clearing heat and detoxicating, tonifying lung and nourishing yin, moistening lung and beautifying, relieving cough and reducing sputum, clearing heart and tranquilizing mind, stopping bleeding and relieving pain, stopping lacrimation, resisting cancer and the like. The lily bulb is rich in nutrient substances, is rich in protein, fat, polysaccharide, vitamins and the like, and the polysaccharide is one of main functional substances in the lily and has various effects of resisting tumors, improving immunity and the like. In addition, the health-care tea also contains various mineral elements, alkaloids, steroid saponins and other components, and has an important effect on human health care. Lanzhou lily is well known as a famous dish due to its sweet and fragrant taste, is a famous Chinese dish with unique flavor, is suitable for frying, stir-frying, steaming, frying, boiling, stewing and the like, and is a precious product in Chinese dishes.

Lanzhou lily has a history of over 130 years in Qinghai and Gansu planting, is mainly distributed in Gansu, Qinghai, Ningxia, Xinjiang and the like at present, has a production area of about 20 ten thousand mu, and is centrally distributed in Guanshan town, Qinghai Min and county, Ledu district and Ping-an district of Qiriheqing, Yuzhong county, Lin Ying county and Yongjing county with the maximum production area of Gansu.
