1、 On the breeding method of Corydalis
1. Illumination
Corydalis was not particularly exposed to light in Europe at the beginning of its growth, so Corydalis formed a characteristic that is not so sensitive to light. But Corydalis still likes sunshine very much. Usually, if you give more light, corydalis will grow branches. It doesn't affect its growth in the dark p>
2. Soil
If the soil is acidic sandy soil with pH between 5.5 and 6.5, it needs good drainage and more organic matter. Peat and Pearl salt can be mixed 1:1 when sowing. Keep the soil moist p>
3. Temperature
The origin of Corydalis determines its tolerance to severe cold, and even mild frost. Corydalis in warm areas such as the South can survive a winter. Corydalis can't be raised in a place with too high temperature. The best temperature is 10 ℃ to 15 ℃. If it exceeds 30 ℃, it can't grow normally p>
4. Fertilization
After the Corydalis seedlings grow young leaves, 50 to 75 ppm nitrogen fertilizer can be used, and then gradually increase the concentration to 100 ppm. Potassium fertilizer should also be supplemented appropriately, and the ratio of the two is 1:1.5. Trace element solution should also be sprayed to supplement Fe and Mg elements p>
5. Pest control
Corydalis may be destroyed by aphids, red spiders, thrips and other pests. We should pay attention to the cleanness of the cultivation environment and not plant in places with pests. Common diseases include leaf ring disease, downy mildew and so on. Controlling soil pH value can also reduce the probability of Corydalis disease p>
2、 Precautions for breeding Corydalis
In the process of Corydalis breeding, if it encounters high temperature weather, it should be cooled in time, and the plants should be placed in a ventilated place to prevent Corydalis wilting. Corydalis can't pour too much water, because Corydalis grows in a cool environment and emits less water, so it doesn't need too much water. Note that it is difficult to have the best growth environment for Corydalis stored indoors and outdoors. Corydalis has relatively little demand for fertilizer. At least it won't burn fertilizer very much. The flowers raised at home should be watered with fertilizer. After watering, pour a little water on Corydalis, and Corydalis will grow healthily and produce small flowers with wonderful colors p>
