The latest cultivation method of Houttuynia cordata

Houttuynia cordata is produced in the provinces south of the Yangtze River Basin in China. As early as the end of 1980s, Gaoping Town, Guanghan City, Sichuan Province was introduced into field scale planting. Now it has driven the planting area of nearly ten thousand mu in surrounding towns and towns, forming the largest planting base of Houttuynia cordata in China at present. Let's take a look at the planting method of Houttuynia cordata together!

The propagation method of houttuynia cordata

The propagation method of houttuynia cordata is divided into plants, cuttings and rhizomes. The ramets are propagated from late March to April, and the mother plants are dug out and transplanted on the seedbed of sandy soil for seedling or direct transplantation. Cutting propagation can be in spring and summer, cut no disease and insect healthy branches as cuttings, cut into 12-15 cm, inserted in flower pots, row spacing 16 cm ×10 cm or 14 cm ×10 cm. Watering after planting, shading, transplanting seedlings after rooting. Rhizome propagation can be carried out in February to March, white and thick rhizomes without disease spots are selected, cut into small segments with more than 2 axillary buds, and seedlings are cultivated or planted in shallow grooves in flower pots. Winter and early spring should pay attention to anti-freezing insulation, summer and early autumn should pay attention to shading moisture.

The planting method of houttuynia cordata

Planting houttuynia cordata should be selected under natural shade (half shade and half sun) and loose and fertile pot soil. It can be planted all year round, but it can be harvested in winter, spring and early summer. Generally, the best time for sowing is around the beginning of spring. Furrows 8-10 cm deep, 13-15 cm wide and row spacing 20-25 cm in the same direction in pots. placing houttuynia seed roots in the grooves, arranging two rows in parallel in each groove, spacing between seed stem segments is 5- 8cm, continuously placing, and connecting head to tail. Seed stems should be placed evenly, then covered with soil, and kept warm and moist after planting. If planted in the hot summer season, there must be 3 nodes to ensure that the middle node can germinate and take root.

If planted before winter, it should also be covered with plastic film or newspaper to facilitate normal growth and development in winter and early spring and obtain high yield.

Daily management of Houttuynia cordata

After planting, seedlings in case of drought, should be watered sooner or later, moist soil. Seedlings survive to the row before closure, intertillage weeding and topdressing 2-3 times, fertilizer mainly nitrogen. 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, nitrogen fertilizer was mainly applied to promote plant germination.

After harvest in autumn, phosphorus and potassium fertilizer should be applied mainly, and soil cultivation should be carried out for winter, laying a good foundation for germination in the coming year. Drought season should be timely irrigation water, rainy season should be timely drainage, avoid pot in a long time ponding.

Weeds should be removed in time, shallow tillage and loosening should be carried out in due time, and appropriate amount of decomposed organic fertilizer should be applied between plants and rows in combination with loosening. For plants with overgrown stems and leaves on the ground, they should be picked to inhibit growth and promote lateral branches.

Harvest and storage of Houttuynia cordata

After planting, tender stems and leaves can be picked when the seedling height is 8-10 cm, and then harvested every 10-20 days. The tender stems and leaves can be picked fresh or dried for marketing. After planting for half a year, the underground stem can be timely dug according to market needs, cleaned and removed impurities, and listed fresh or used for submerged processing.

Underground stems reserved for seed can be picked as needed. Houttuynia cordata herb can be used for medicine, can be harvested at any time, washed and dried for storage or marketing.
