How to plant andrographis paniculata

Andrographis paniculata is a well-known medicinal material, which belongs to annual herbs and is widely cultivated in the south of China. Andrographis paniculata is not only a kind of medicine, but also can be fried as a vegetable. It has the effect of heat-clearing and detoxification, anti-inflammation and pain relief. It has the value of food and medicine, so its planting area must be not small, and now there are new farmers. So how to grow andrographis paniculata? Let's take a look at it with the editor.

1. Land selection and preparation

Andrographis paniculata is a wet crop, it can adapt to high temperature and is also very suitable for growing in high temperature environment. Planting andrographis paniculata needs sufficient sunshine and nutrition. After germination and emergence of andrographis paniculata, the temperature should be controlled at 28 degrees. If the temperature is below 20 degrees, it will slow down the growth rate of the seedlings, and when the temperature is below 8 degrees, the plants will stop growing. Therefore, we should choose the planting land on the acid soil with sufficient fertility, loose soil, good permeability and strong thermal insulation. After selecting the soil, we should prepare the soil in time, and the depth of soil preparation should not be lower than 30cm. When preparing the soil, we need to pick out all the weeds in the soil, apply enough base fertilizer after ploughing, and then do a good job of soil disinfection.

2. Sowing seeds at the right time

Choose good seeds with no disease, good genes and no crack wounds, sow time to avoid cloudy and rainy weather as far as possible, and sow the number according to the planting area. Do a good seed treatment before sowing, wash the seeds, and then mix them in firewood ash, because firewood ash can promote seed germination and improve growth rate. After mixing, the seeds are sown on the soil, and then covered with a layer of soil about 1cm. The main purpose of spraying with double rose agent is to reduce the incidence of quenching disease and blight disease, and then do a good job of soil water and fertilizer conservation.

3. Field management

After sowing, when the seedlings grow to a certain extent, they should be transplanted in time to maintain a reasonable planting density. After transplanting, the seedlings should be watered in time to promote the root growth of the seedlings, and then the intertillage should be carried out about 2-3 weeks, and the intertillage should be carried out with topdressing. More nitrogen fertilizer should be applied when topdressing, and fully mature farm manure can be used. Management is very important in summer, which is a critical period for the growth of andrographis paniculata, when we need to increase the frequency of topdressing and watering. To promote the growth of the plant, when the plant grows tall, it is necessary to cultivate the soil in time to prevent lodging.

4. Pest control

The main diseases of andrographis paniculata are standing blight and sudden fall, which usually occur when the seedlings grow about two leaves. After the disease, watering should be controlled to prevent the soil from being too wet, and then carbendazim and other agents should be used for prevention and control. Pay attention to the ventilation of the garden, control the surrounding environment, especially the temperature, too low temperature will hinder the growth of the plant, strengthen the permeability of the countryside, pull out the diseased plant in time, and do a good job of pruning and pruning. Reduce the conditions of the disease and reduce the incidence.

So much for the introduction of the planting method of andrographis paniculata. Andrographis paniculata is a medicinal plant with high economic value. Regular consumption of andrographis paniculata can effectively enhance the resistance of the human body. Although the current planting area is not very extensive, but with the improvement of awareness, the expansion of market demand, planting personnel will be more and more, so andrographis paniculata still has a certain planting prospect. However, we should consider all aspects carefully before planting, so that the bamboo basket will not be in vain.
