What is the difference between Lu Binghua and Lu Binghua?

I. planting method of Digitalis

1. Soil: Digitalis is suitable to grow on moist and well-drained soil.

3. Illumination: Rehmannia glutinosa is also resistant to semi-shade, which can be planted in sunny places or semi-shady places where there is enough scattered light. In the flowering season, light can be increased appropriately, taking into account the quality and quantity of flowers. The length of sunshine will not affect flowering.

4. Temperature: the temperature adaptation range of Digitalis growth is 12 ℃-19 ℃, but the ideal night temperature in the final stage is 12 ℃-16 ℃. When plants are planted under the condition of a certain protective cold bed, they can grow high-quality plants and spikes of flowers.

5, fertilization: sex like fertilizer, the growth period of about 20 days to apply full-effect organic liquid fertilizer, nitrogen, phosphorus and potassium compound fertilizer or 0.2% potassium dihydrogen phosphate solution.

6. insect diseases: Fusarium wilt, mosaic disease and aphids often occur in Rehmannia glutinosa. When causing the main disease, remove the diseased plant in time and disinfect it with lime. When insect pests occur, it can be sprayed with 2000 times of omethoate EC, which can also reduce the incidence of mosaic disease.
