The planting method of Rabdosia mandshurica

1, humidity management: like the dry air environment, overcast and rainy days are too long, easy to be infected by bacteria. For fear of rain, keep the leaves dry at night. The optimum air relative humidity is 40-60%.

2. Temperature management: like cool climate, avoid extreme heat, frost and cold resistance. The requirement of winter temperature is not very strict, as long as it can survive the winter safely without frost, it dies when the temperature is above 30 ℃ in late spring and early summer, and the most suitable growth temperature is 15-25 ℃.

3. Light management: in late autumn, winter and early spring, because the temperature is not very high, it is necessary to give it direct sunlight to facilitate its photosynthesis and the formation of flower buds, flowering and fruiting. If you encounter hot weather in summer, you need to shield it from about 50% of the sun.

4. Fertilizer and water management: Artemisia mandshurica has more requirements for fertilizer and water, but it is afraid of random fertilization, concentrated fertilizer and partial application of nitrogen, phosphorus and potash fertilizer. It is required to follow the two fertilization principles of "frequent application of light fertilizer, less and more times, complete nutrition" and "dry and wet, dry and dry." watering will water thoroughly ", and after fertilization, leaves and flowers should be kept dry at night.

Matters needing attention in maintenance of Artemisia mandshurica

① has a long taproot and is not resistant to transplanting. Before sowing, apply some rotten bean cake as base fertilizer and sow the seeds directly in the basin.

The root of ② flower rhombus is fleshy, afraid of waterlogging, and it is easy to blacken and rot around the root neck in rainy season, so open-field cultivation in summer should pay attention to timely drainage; pot watering should be appropriate.

③ should not be watered too much during the peak growing season and before flowering, and the mature thin cake fertilizer should be applied once a month to make the plant grow well.

The harm of whitefly is more during the growth of ④, so we should pay attention to the control and the combination of control.

After the pericarp of ⑤ turns yellow, it should be harvested in time in the early morning, otherwise the seeds will be scattered easily. When drying the capsule, pay attention to cover the glass on the container, because after drying, the peel burst very violently, the seeds will pop out of the container, which is not conducive to seed harvest.
