Detailed Explanation of Golden Yulan Vegetable Planting Techniques and Management Points

Golden Yulan vegetable, also known as European chicory, is a common vegetable found along rivers and ditches in Beijing, Xinjiang, Jiangxi and other places. Because its leaves can be prepared as lettuce and its roots can be used to make a coffee substitute, it has high value for promoting the activity of the human digestive organs. At present, some regions are experimenting with cultivation, so what are the Golden Yulan vegetable planting techniques?

Golden Yulan vegetable cultivation includes fleshy root cultivation, frozen storage and hydroponics. The detailed steps are as follows:

1. Fleshy root cultivation

1. Land selection and preparation

Choose a field with sufficient fertility, deep plow it and apply 3000 kg of organic fertilizer and 20 kg of calcium phosphate, then level it for later use.

2. Seed treatment

Select healthy, plump seeds, dry them and soak them in cool water, then remove them and drain the water for later use.

3. Sowing

(1) Sowing time: June to July

(2) Sowing method: Open shallow furrows in the field at a row spacing of 25 cm, cover with soil after sowing, cover with plastic film and water thoroughly.

(3) Management techniques after sowing: After emergence, cut open the plastic film. From 20 to 30 days after emergence, apply nitrogen fertilizer 1 to 2 times, loosen the soil and weed. During this period, observe the degree of dryness and wetness of the field and water appropriately. After 3 months, spray the leaves 1 to 2 times with 0.3% potassium dihydrogen phosphate to promote the growth of fleshy roots.

4. Digging roots and sun-drying

From October to late November, dig out the entire fleshy root, remove withered yellow old leaves, keep 1 cm of petiole at the leaf base, and sun-dry them in the sun.

2. Frozen storage

Stack the sun-dried fleshy roots in boxes and transport them directly to a cold storage at minus 18 degrees Celsius. After freezing for a period of time, raise the temperature to minus 7 degrees Celsius for long-term storage.

3. Hydroponic method

1. Thawing: Place the fleshy roots in a constant-temperature environment of 0 degrees Celsius to thaw for 2 days.

2. Cleaning: Remove the root tips of the fleshy roots and wash them clean, then place them in a culture tray with flowing water, with the water level at half the height of the fleshy roots. Then control the humidity of the growing environment at 92 to 95% and keep the temperature at 18 to 20 degrees Celsius for 7 days of growth. After lowering the temperature by 1 degree Celsius, continue growing for 7 days, then continue lowering the temperature by 1 degree Celsius and grow for another 7 days.

3. Hydroponics: Cut the base of the bud ball, peel off damaged outer leaves, and after packaging, store it in a 0 degrees Celsius environment to complete hydroponics.

Overall, the cultivation of Golden Yulan vegetable is relatively complicated and has relatively harsh requirements for growing conditions, so there are currently very few regions where it can be grown. However, if you want to try it, you can refer to the method above.
