What are the propagation methods for kudzu root? A detailed explanation

Kudzu root can be eaten raw, made into kudzu powder, and also used as medicine. It is a crop with extremely high economic value and is grown in most parts of our country. In addition to the sowing propagation method, there are several other propagation methods. Let's take a look together below.

1. Seed propagation

Every year in September-October, when the pods mature, harvest the pods, dry them in the sun, thresh them, remove impurities, and keep the seeds stored for later use. In the spring of the following year, when the temperature rises, choose a suitable time to prepare for sowing. First choose a sandy loam field with deep soil and good drainage, apply base fertilizer while preparing the land, and then sow. Sowing can be done in holes or in rows. When sowing, pay attention to the sowing density, and thin the seedlings in time after they emerge. Combine with cultivating and weeding, and when the seedlings grow to a certain extent, transplant them at the appropriate time.

2. Cutting propagation

For cutting propagation, select robust kudzu vines that have grown for 1-2 years from the mother plant, cut them into sections with every 2-3 stem nodes, and insert them into loose, moist soil or fine sand. Using their regenerative ability, they can take root after about one month, and soon form new plants. Because cuttings are in short supply, this method is not suitable for propagating seedlings in large quantities, and its disease resistance is relatively weak. It is very easy for a large number of viruses to accumulate, causing the variety of kudzu root to degenerate and reducing yield and quality.

3. Root head propagation

Root head propagation, as the name suggests, uses the underground rhizome of kudzu root for propagation. When digging and harvesting in winter, cut off about 10 cm of the root head from the robust root system and plant it directly into the production field. After the spring of the following year, new seedlings can grow. When the seedlings grow to a certain extent, transplant them to the planting field in time.

4. Layering propagation

Layering propagation is somewhat similar to cutting propagation. It is generally carried out in summer. When the plants grow luxuriantly in summer, select robust, disease-free kudzu vines. At every 1-2 nodes, loosen the soil below the node, pile soil over the node, and press the node into the soil. The stem nodes buried in the soil can be cut with a knife in several places. Water during drought to help them take root as much as possible. After rooting, apply dilute fertilizer water in time and remove weeds. After the following spring when shoots emerge, cut them off to become individual plants, then lift the seedlings and transplant them.
