Planting method of Corydalis

Light requirements: Corydalis does not require high light, and can grow normally in the dark. Soil requirements: it is better to choose the slightly acidic soil with the PH value of about 5.56.5. Growth temperature: the best growth temperature is 10-15 ℃. Timely watering: less water is usually needed, and more water is needed in the flowering period. Rational fertilization: nitrogen fertilizer is applied when the seedlings grow tender leaves, and potassium fertilizer and other trace elements can be applied in the later stage. Prevention and control of diseases and insect pests: controlling soil PH value can reduce the incidence.

1. Lighting requirements

1. The origin of Corydalis is in Europe, because the latitude is relatively high, the light is not very strong, and the sensitivity of Corydalis itself to light is not as high as that of tropical and subtropical flowers, so it will not affect its normal growth even in the dark.

2. Corydalis is actually more fond of sunshine. If you usually have more light, it will grow a lot of branches.

II. Soil requirements

The main results are as follows: 1. Corydalis is suitable to grow in acidic soil with PH value of about 5.5-6.5. it requires good soil drainage condition and more organic matter.

2. Before sowing, the ratio of peat and pearl salt at 1:1 can be used to mix, and the soil must be kept moist.

Third, growth temperature

1. Because Corydalis originated in the high latitudes of Europe, the temperature is relatively low, so Corydalis is more resistant to severe cold, and can even withstand mild frost. Corydalis growing in warm areas such as the south can safely survive a winter.

2. Corydalis is not suitable to be planted in the place where the temperature is too high, the best temperature is 10-15 ℃, and it can not grow normally when it is more than 30 ℃.

Fourth, timely watering

1. Because Corydalis generally grows in a cool environment, water emanates slowly, so it does not need to be watered too much.

2. In the flowering stage of Corydalis, the demand for water will increase, because the temperature begins to rise, water evaporates faster, and energy is needed during flowering, so the amount of water consumed will increase.

3. Especially after the Spring Festival, when the temperature rises to 12-20 ℃, it needs to be watered once a day in order to ensure the moisture needed for Corydalis to bloom.

V. rational fertilization

1. Corydalis is generally planted by sowing, and it can be fertilized after the seedlings grow tender leaves. 50-75% nitrogen fertilizer can be used, and then the concentration can be gradually increased to 100% according to its growth.

2. In the later stage, it is necessary to properly supplement potash fertilizer, spray trace element solution and supplement iron and magnesium.

VI. Prevention and control of diseases and insect pests

Corydalis should not be planted in places where there are pests. The pests of Corydalis include aphids, red spiders, thrips and other pests. Common diseases include leaf ring disease, downy mildew and so on. Controlling the PH value of the soil can also effectively reduce the incidence.
