Problems solved by technology

After the angelica seedlings are harvested, place them for 10-15 days to make the seedlings lose part of their moisture and store after the stalks fall off. If the temperature drops slowly before storage, it is difficult for the seedlings to enter a dormant state, and some seedlings will heat up or continue to grow after storage. ; During the medium storage period, the external temperature is too low to cause chilling damage to the seedlings; the temperature changes greatly before the spring thaw, which is easy to cause the seedlings to pass the vernalization physiological stage, and the early bolting rate of the seedlings after transplanting increases, causing adverse effects on the production of Angelica sinensis , which is also the main reason for the early bolting of seedlings after transplanting;
[0006] (2) The phenomenon of rotten seedlings and inhibited growth of seedlings during storage is common
When the seedlings are stored, the seedlings are wrapped with pastoral soil. Harmful germs in the soil will cause the seedlings to rot. In order to reduce the rotten seedlings, farmers need a lot of raw waste soil or add fungicides to the seedling storage soil. The amount of fungicides is not good. It will have an inhibitory effect on seedlings, resulting in a decrease in the survival rate of seedlings transplanted in the next year, and it is difficult to guarantee the quality of seedlings;
[0007] (3) A large amount of raw waste soil is used for storage, which requires a large amount of labor
The traditional seedling storage method requires a large amount of raw waste soil to separate the seedlings from each other, so that a raw soil isolation zone is formed between the seedlings. It takes 3-5 tons of raw waste soil to store 1 ton of seedlings. The cost of soil extraction is time-consuming and will lead to severe damage to wasteland;
[0008] (4) Improper storage will lead to a sharp increase in the bolting rate of seedlings after transplanting

Embodiment 1

[0042] A method for storing angelica seedlings, comprising the steps of:

[0043] (1) Harvesting of seedlings: Select the three-year-old seeds of the excellent Angelica sinensis variety "Mingui No. 1" for seedling cultivation, and choose sunny days for excavation when the seedling age reaches 90 days. When the seedlings are excavated, the leaves and stems are twisted off, and 3-5cm petioles are reserved at the base of the seedlings, and then packed into woven bags and transported back to the processing workshop.

[0044] (2) Seedlings sweating and dehydration: place the recovered seedlings in a cool place at 3-5°C, and plant them in wet soil with a water content of 50% with an inclination of 30°. The planting time is 15 days. The reserved petioles wilt and fall off, the seedlings lose 20% of their moisture, and the seedlings enter the dormancy period.

[0045] (3) seedling selection: the seedlings that have entered dormancy in step 2 are selected, the residual petioles of the s...

Embodiment 2

[0054] A method for storing angelica seedlings, comprising the steps of:

[0055] (1) Harvesting of seedlings: Select the three-year-old seeds of the excellent Angelica sinensis variety "Mingui No. 1" for seedling cultivation, and choose sunny days for excavation when the seedling age reaches 90 days. When the seedlings are excavated, the leaves and stems are twisted off, and 3-5cm petioles are reserved at the base of the seedlings, and then packed into woven bags and transported back to the processing workshop.

[0056] (2) Seedlings sweating and dehydration: place the recovered seedlings in a cool place at 4-5°C, and place them in a wet soil with a water content of 60% with a 45° inclination. The time of artificial planting is 12 days. The reserved petioles wilted and fell off, the seedlings lost 16% of their moisture, and the seedlings entered the dormancy period.

[0057] (3) Seedling selection: the seedlings that have entered dormancy in step 2 are selected, the residual...

Embodiment 3

[0066] A method for storing angelica seedlings, comprising the steps of:

[0067] (1) Harvesting of seedlings: Select the three-year-old seeds of the excellent Angelica sinensis variety "Mingui No. 1" for seedling cultivation, and choose sunny days for excavation when the seedling age reaches 100 days. When the seedlings are excavated, the leaves and stems are twisted off, and 3-5cm petioles are reserved at the base of the seedlings, and then packed into woven bags and transported back to the processing workshop.

[0068] (2) Seedlings sweating and dehydration: place the recovered seedlings in a cool place at 4-5°C, and place them in a wet soil with a water content of 70% with an inclination of 45°. The time of artificial planting is 10 days. The reserved petioles wilt and fall off, the seedlings lose 15% of their moisture, and the seedlings enter the dormancy period.

Abstract

The invention discloses a storage method for Chinese angelica seedlings. The storage method includes the steps of 1) seedling harvesting, 2) seedling dehydration, 3) seedling selection, 4) seedling sterilization, 5) preparation of seedling storage media, 6) seedling packing, 7) seedling warehousing, 8) seedling storage, 9) seedling removal from a warehouse, and 10) inspection. The storage method has the advantages that the efficiency is improved, and the cost is saved; through seedling treatment, diseases of stored seedlings are reduced; the storage temperature of the seedlings is controlled,and the bolting rate in transplanting is reduced; the seedlings are uniform, and mechanical transplanting is facilitated.

Description

technical field [0001] The invention relates to the technical field of production of Chinese medicinal materials, in particular to a method for storing angelica seedlings. Background technique [0002] Angelica sinensis (Oliv.) Diels is an herbaceous plant belonging to the genus Angelica sinensis of the Umbelliferae family, and its dried roots are used as medicine. Angelica was first recorded in "Shen Nong's Materia Medica", and was listed as a middle grade. Angelica has the functions of nourishing blood, harmonizing blood, regulating menstruation and stopping bleeding, and moistening intestines. It is one of the commonly used traditional Chinese medicines and is called "the holy medicine of gynecology". Angelica cultivation has a history of more than 1,700 years. It is mainly cultivated in alpine and damp mountainous areas at an altitude of 2000-3000m. Minxian County is the most traditional and authentic and has the largest yield. Minxian County, Gansu is known as the "Hom...
