II. Planting techniques

Before soil preparation, after ploughing and harrowing, apply organic fertilizer as base fertilizer, before planting, add 1500tel 2500kg mature organic fertilizer plus appropriate amount of plant ash (per mu) into the planting ditch as base fertilizer, and fully mix well with the soil, then cover with 3 cm thick crushed mud, wait for maturity (to avoid rotting roots), turn it again, and open into a low bed 1.3mer 1.5 meters wide, and then horizontally dig a planting ditch 15 cm wide and 20 cm deep, with a spacing of about 25 cm.

two。 Seedling planting

Houttuynia cordata Thunb mainly uses underground stems for asexual reproduction. Houttuynia cordata Thunb has two kinds of white stem and red stem, and the red stem houttuynia cordata has a stronger flavor. It is generally suitable to dig up its sturdy underground stem as a seedling in winter and bury it under the loose soil to survive the winter. After sprouting in the following spring, it will be dug up and cut into small segments (each section has 2 Mel and 3 nodes), and then planted.

3. Planting management

Winter planting is planted in January and can be harvested in April, or the aboveground stems and leaves can be harvested first, and the aboveground stems and leaves can be harvested for the second time after topdressing as the root of spring planting. Planted before and after the Qingming Festival in spring. Put a seedling every 6mur8 cm, then cover it with crushed mud 7cm thick, and water it as appropriate. After planting, pay attention to moisturizing and drought prevention. In the case of adequate base fertilizer, there is generally no need to topdressing. When necessary, dung water can also be applied thinly in the prosperous period to promote yield increase and harvest. The key to daily management is to keep the soil moist and do not suffer from drought, otherwise, there will be many roots and poor quality. Pay attention to weeding in the early stage, and there is no need to weed after closing the line. Rare manure was applied once before the seedling height of 5 cm and before sealing. In addition, when the bud just appears, it should be removed as soon as possible, combined with a heart pick, in order to restrain its overgrowth. Houttuynia cordata Thunb diseases and insect pests are very few, and root rot is occasionally seen, which can be controlled by methyl thiophanate solution spray. When the plant height is more than 10 cm, the soil should be cultivated in time to make the underground stem long and white.
