1. The growth habits and choice of planting land of Houttuynia cordata
Because Houttuynia has a warm and humid environment, it is not resistant to drought, but it can adapt to the cold environment, and it is afraid of strong direct sunlight. It can also be wintered at minus 15 °C. Therefore, the soil planted by Houttuynia cordata grows best with fertile sandy loam and humus loam, and is not suitable for cultivation in clay and alkaline soil.
2. Method of planting Houttuynia cordata
Houttuynia is best propagated by rhizome: in spring, the roots of the old seedlings are excavated, and the white and thick rhizome is cut into 10-12cm segments, each with 2 buds, planted at a row spacing of 20cm*20cm, and propagated. Covering soil 3-4cm, watering after a little suppression, can grow sprouts after one week. Spraying a new high-fat film on the surface of seedling plants can prevent the infection of pathogens, increase the photosynthesis intensity, and protect the growth of the seedlings.
3. Field management of Houttuynia cordata
Houttuynia should be carefully watered after planting, and the soil should be kept moist. After the emergence of Houttuynia cordata, it is necessary to diligently remove the weeds in the field. If the upper part of the fish hoe grass is closed, it is possible not to carry out weeding, so as not to damage the roots of Houttuynia cordata.
According to the habit of Houttuynia, Houttuynia is still very easy to grow and live. In the process of planting some agricultural techniques in accordance with the correct method, Houttuynia will generally produce high quality and good economic benefits.
