Cultivation methods and precautions of Silybum marianum

Soil: Sandy loam soil is suitable for raising golden safflower. The soil layer is loose and has good drainage performance, which is helpful for the growth of the plant. Moisture: You will need a lot of water during the growing season, so wait until the soil layer is dry and start watering, but you should also control the amount of water properly. Temperature: During the breeding period, the temperature should be controlled well, the daytime temperature should be about 25 ℃ -28 ℃, and the night temperature should be about 15 ℃ -18 ℃. Illumination: Do not like strong direct light, suitable for growth in semi-shade environment, astigmatism irradiation is also possible.

1. Soil

Milk thistle does not have a strict soil requirement, preferring flat, well-drained, moderately fertile land.If the soil fertility is too large, it will seriously affect the growth of seedlings, which is not conducive to seed bearing, and the general sandy land is not suitable for planting milk thistle.

2. Fertilization

In the growth process of milk thistle, attention should be paid to seed fertilizer and fertilization, first turn the land deeply, and then turn the soil layer.Fertilization should be carried out according to the barren degree of soil, and 18-20 kg of phosphorus and potassium can be applied to each mu of barren land.

3. Temperature

Milk thistle is very cold-resistant, usually if the temperature is relatively low, its leaves will become dark.When the temperature rises, the leaves will return to normal.Generally, the ideal growth temperature of Silybum marianum is about 15 ~ 20 , at which the fruiting rate is the highest.

4. Watering

Milk thistle is very afraid of drought in the early stage, especially in spring, so it should be watered in time and properly.However, do not pour too much water, to the latter part of the appropriate amount of watering, slightly wet state is better.
