Planting technique of Magnolia lanceolata

Magnolia, also known as European chicory, is Beijing, Xinjiang, Jiangxi and other riverside, ditch side common vegetables, because the leaves can be adjusted to make lettuce, root can be extracted substitute coffee, promote human digestive organs activities and has a higher value, at present some areas are trying to cultivate, that Magnolia planting technology what?

The planting of Magnolia chinensis includes fleshy root cultivation, frozen storage and hydroponics, and the detailed steps are as follows:

1. Succulent root cultivation

1. Land selection and preparation

Select a fertile field, deep tillage and apply 3000 kg organic fertilizer and 20 kg calcium phosphate, and finally level it for later use.

2. Seed treatment

Choose healthy, plump seeds, dry them, soak them in cold water, remove them and drain them for later use.

3. Sowing

(1)Sowing time: June ~ July

(2)Sowing method: in the field by 25 cm row spacing open shallow ditch, after sowing soil, plastic film irrigation water.

(3)After sowing management technology: after emergence, draw film, 20~30 days after emergence, topdressing nitrogen fertilizer 1~2 times, loosening weeding, during which observe the dry and wet degree of the field, appropriate watering. After 3 months, 0.3% potassium dihydrogen phosphate was sprayed on leaves for 1~2 times to promote the growth of fleshy roots.

4. Digging roots and drying

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

II. Frozen storage

The dried meat root code is placed in a box, directly transported to a cold storage at minus 18 degrees Celsius, frozen for a period of time, and then heated to minus 7 degrees Celsius for long-term storage.

3. Hydroponic method

1. Thawing: Place the fleshy roots in a constant temperature environment of zero degrees Celsius for thawing for 2 days.

2. Cleaning: Remove the root tips of the fleshy roots and clean them, put them into a culture dish with flowing water, and the water level is half of the fleshy roots. Then the growth environment humidity is controlled at 92 - 95%, and the temperature is maintained at 18 - 20 DEG C for 7 days. After cooling down by 1 degree Celsius, it continues to grow for 7 days, and then continues to grow after lowering the temperature by 1 degree Celsius for 7 days.

3. Hydroponic culture: cut the base of the bud ball, strip off the damaged outer leaves, pack and store in an environment of zero degrees Celsius to complete hydroponic culture.

Generally speaking, the planting of Magnolia is complicated and the growth conditions are relatively harsh, so there are few areas that can be planted at present. But if you want to try it, you can refer to the above method.
