1、 Suitable temperature

Andrographis paniculata likes hot and humid climate. I like sunny and fertile soil. The suitable temperature for seed germination and seedling growth is about 25 ~ 30 ℃. When the temperature drops to 15 ~ 20 ℃, it will grow slowly; When the temperature drops to about 8 ℃, it will no longer grow. When the temperature is below 0 ℃, all the plants will wither. Therefore, it is best to choose sandy soil with fertile, loose and good permeability for cultivation

2、 Transplanting

When Andrographis paniculata grows to a height of about 6cm and grows 3-4 leaves, it can be transplanted. It is best to water the seedbed before transplantation, so as to facilitate the seedling with soil, and the survival rate will be very high. Also choose to transplant in the evening or cloudy days, according to the plant spacing of about 25 cm. Water immediately after planting. It is advisable to water once a day. Also loosen the soil slightly for it, which is conducive to its growth

3、 Fertilization

1. Maifan stone fertilizer method: a layer of Maifan stone particles can be sprinkled on the soil of the flower pot, which can not only promote the growth of flowers, but also prolong the flowering period

2. Broken eggshell fertilizer method: crush the eggshell and bury it in the soil of the flowerpot, which can make it grow luxuriant, colorful flowers and leaves

3. Cooked soybeans: you can dig three small holes in the flower pot, put three or five to two or three deep, and cover them

4. Rice washing water: rice washing water not only does not hurt flower roots, but also a mild compound fertilizer

4、 Pest control

1. Verticillium wilt: it will occur in 1-2 pairs of true leaves. 50% carbendazim can be used to treat the soil, or 1000 times of liquid can be used to irrigate the sick area

2. Sudden collapse disease: if 2-3 pairs of true leaves occur, be sure to control the temperature, pay attention to ventilation and strengthen the management of the seedbed

3. Black stem disease: it usually occurs in the adult stage. Usually, we should pay attention to the timely removal of ponding, strengthen management and avoid continuous cropping

4, Phytophthora: 50% of carbendazim or 1000 times of spray. p>

In addition, we must control cotton bollworm, mole cricket and virus diseases
