More and more medicine farmers pay attention to its planting. The efficient planting method is introduced as follows.

According to the characteristics of strong root growth, many fibrous roots and luxuriant stems and leaves, Houttuynia cordata Thunb grows underground for 2/3 of the time, grows roots on the ground for 1/3 of the time, and grows long stems and leaves under the strong sunlight. Short-term vegetables are planted on the soil covered by Houttuynia cordata Thunb. Growing short-term vegetables not only does not affect the growth of Houttuynia cordata, but can promote the growth of Houttuynia cordata, because when applying sufficient fertilizer and water to the above vegetables, Houttuynia cordata is absorbed at the bottom, so it can make the fish fishy: the root length is thicker and more.

The cultivation of Houttuynia cordata Thunb is cultivated in sandy loam with loose fertilizer, convenient drainage and irrigation, leeward and sunny soil or soil rich in organic matter. Before and after the Beginning of Summer, after deeply ploughing and loosening the soil, the border was widened by 1.5m~1.6m, the height of the border was 30cm, the width of the ditch bottom was 20cm, and the miscellaneous fertilizer 3000kg~4000kg of farm soil was applied as base fertilizer per mu. According to the row spacing of 14 × 20cm, the seed root of Houttuynia cordata was put into the ditch, and then covered with soil, flat was better. Then grow short-term vegetables on the covered soil, usually half a month or January, because short-term vegetables need enough fertilizer and water. About a month later, Houttuynia cordata Thunb gradually grew and 3cm should no longer grow vegetables. At this time, it is the midsummer season, when Houttuynia cordata Thunb grows stems, leaves and roots, and its growth period is about four months.

Between the seasons of Cold Dew and Frosts Descent, the stem of Houttuynia cordata was cut off flat, dried and used medicinally or edible. Then cover the cut Houttuynia cordata with about 3cm~5cm soil, and then plant short-term vegetables on the covered soil. Around February of the following year, Houttuynia cordata Thunb sprouted and grew out of the ground. At this time, use a shovel or hoe to shovel the new buds of Houttuynia cordata from the old root of Houttuynia cordata, about 10cm, to sell at a high price. The soil cover is still restored after the shovel, and short-term vegetables are planted on the soil after the cover is reduced.
