Houttuynia cordata has become a food on the table of the people because of its unique taste and refreshing taste. The following is a description of the planting techniques for potted Houttuynia cordata.
Potted houttuynia
Planting method: The method of breeding Houttuynia cordata can be carried out by using ramets, cuttings and roots.
(1) The ramets are propagated from late March to April, and the mother plants are excavated and transplanted on the seedbed of the sand to grow seedlings or directly transplanted.
(2) Cutting and breeding can be carried out in spring and summer, cutting out the disease-free insects and strong branches for cuttings, cut into 12--15 cm, inserted in pots, row spacing 16cm × 10cm or 14cm × 10cm. After pouring, watering, shading, rooting and transplanting seedlings.
(3) Rhizome propagation can be carried out from February to March. The roots with no lesions, white and stout are selected, and cut into small segments with more than 2 axillary buds. Seedlings or colonization are carried out in shallow pots in pots.
Daily maintenance points
(1) Temperature and humidity: Houttuynia is afraid of frost, is not resistant to drought and watery, and is resistant to negative. The temperature in the early stage of Houttuynia cordata is 15-20 °C, and the suitable temperature in the mature stage of the underground stem is 20-25 °C. Winter and early spring should pay attention to antifreeze and heat preservation. In summer and early autumn, attention should be paid to sunshade and moisturizing. It is required that the relative humidity of the soil is about 80%, and the relative humidity of the air is between 50% and 80%, in order to grow normally.
(2) Watering and fertilization: After planting, when the seedlings encounter drought, they should be watered in the morning and evening to moisten the soil. Seedlings survive until the closure of the line, cultivating weeding and topdressing 2--3 times, the fertilizer is mainly nitrogen fertilizer. Each time weeding combined with topdressing, 20~30 grams of urea can be applied per square meter, first diluted and then concentrated. After each harvest, the application of nitrogen fertilizer is mainly to promote the germination of the plant; after harvesting in the autumn, the application of phosphorus and potassium fertilizer is the main, and the soil is used for the wintering, which lays a foundation for the germination in the coming year. Water should be watered in a timely manner during the dry season, and should be drained in time during the rainy season.
(3) Weeding and topping of loose soil: If weeds are found to be removed in time, we can carry out shallow cultivating loose soil in time, or combine with loose soil for fertilization. Topping is carried out to suppress its growth and height, and it also promotes the occurrence of side branches.
Houttuynia
Houttuynia is planted, and when the seedling grows to a height of 8 to 10 cm, it can start to pick up its tender stems and leaves. It can be harvested for ten days and a half, and can be dried or collected without eating. The processing and processing of the underground stems for seeding can also be used with the harvest, and the whole plant can be used for medicinal purposes.
