Andrographis paniculata enjoys a hot and humid climate. I like sunny and fertile soil. When seeds germinate and seedlings grow, the appropriate temperature is about 25-30 ℃. When the temperature drops to 15-20 ℃, they will grow slowly. When the temperature drops to about 8 ℃, they will no longer grow. When the temperature is below 0 ℃, the plants will all wither. Therefore, it is best to choose the soil with fertile, loose and good permeability for cultivation.
When the height of Andrographis paniculata is about 6cm and there are 3-4 leaves, it can be transplanted. Before transplanting, it is better to water the seedbed to facilitate the seedling with soil, and the survival rate will be very high. In the evening or cloudy days, transplanting should be carried out according to the plant spacing of about 25 cm. Water and irrigate immediately after planting. It's better to water once a day. But also for it a little loose soil, which is conducive to its growth
1. Maifanshi fertilizer method: sprinkle a layer of Maifanshi particles on the soil of the flowerpot, which can not only promote the growth of flowers, but also extend the flowering period.
2. The method of breaking eggshell fertilizer: crushing eggshell and burying it in the soil of flowerpot can make it grow luxuriantly, with colorful flowers and leaves.
3. Cooked soybeans: you can dig three small holes in the flowerpot, put three or five into two or three, and cover them.
4. Rice washing water: rice washing water is not only not harmful to flower roots, but also a mild compound fertilizer.
1. Bacterial wilt: it will have 1-2 pairs of true leaf periods. 50% carbendazim can be used to treat the soil, or 1000 times of liquid can be used to irrigate the disease area.
2. Cataplexy: if there are 2-3 pairs of true leaves, it is necessary to control the temperature, pay attention to ventilation, and strengthen the management of the seedbed.
3. Black stem disease: it usually occurs at the mature stage. Usually, we should pay attention to timely drainage of water, strengthen management, and avoid continuous cropping.
4. Epidemic diseases: 50% of carbendazim or 1000 times of liquid spray should be used in the epidemic stage.
In addition, we must also control cotton bollworm, mole cricket and virus diseases.
