Method for increasing carum carvi in surface layers of soil in high-cold regions in cold seasons by means of stratification

Abstract

The invention relates to a method for increasing caraway seeds by layering the surface layers of cold-season soil in alpine regions. The method comprises the following steps: (1) collecting seeds: harvesting mature caraway seeds and storing them indoors after air-drying; (2) alpine meadow soil Stratification treatment: from mid-October to late October, bury the caraway seeds obtained in the step (1) in the topsoil of the alpine region or the topsoil with a similar climate to a depth of 1 cm, and retrieve it at the end of March next year; The caraway seeds obtained in the step (2) are directly used for sowing, or stored after being dried. The invention can effectively break the dormancy of caraway seeds, and the germination rate can reach more than 92%, and the germination is rapid and uniform. After topsoil accumulation in cool season, it is suitable for sowing in spring or early summer, which is conducive to the artificial establishment of caraway seeds.

Description

technical field [0001] The invention relates to a method for cultivating caraway seeds, in particular to a method for increasing caraway seeds by stratifying the surface layers of soil in cold seasons in alpine regions. Background technique [0002] Caraway ( Carum carvi L), also known as Tibetan fennel, is a perennial herbaceous plant of the genus Caraway in the Umbelliferae family, distributed in West Asia, Europe, Northeast my country, North China, Northwest China, Sichuan, Tibet and other places. Caraway has been used in Europe since ancient times as an aromatic carminative and spice. In my country, caraway is not only used as a seasoning, but also one of the commonly used Tibetan medicines. Caraway seed is warm in nature, slightly pungent in taste, and has the effects of regulating qi, relieving pain and detoxifying. Caraway seeds contain essential oils (3%~6%), which are widely used as food additives, flavoring agents and cosmetic essences. [0003] Since Tibetan f...

Problems solved by technology

[0005] However, at present, caraway seeds in my country are still in a wild state, and the seeds have a long dormancy period and a low germination rate.

After 6 and 18 months of dry storage at room temperature, the germination rates of caraway seeds were 18.0% and 61.3%, and the germination duration required 45 days and 30 days. On days 10 and 6, the germination is irregular, which limits the cultivation or planting of caraway seeds
