The latest breeding method of Vitex mandshurica

Vitex trifoliata L. is the fruit of Vitex trifoliata L. and has high medicinal value. It is mainly distributed near the water and has a large planting area in the coastal provinces of China. Vitex fruit can be used by anyone except those with weak stomachs. It has the effects of pungent energy dispersing wind, slight cold and clearing heat. So how do we reproduce when we plant vitex? The following small series brings you the breeding method of Vitex trifoliata. Let's take a look together!

1. Cutting propagation

The time of cutting propagation of Vitex trifoliata is generally in spring and autumn, but it is usually appropriate in spring. First select 1-2 years old stout branches, cut them into about 25 cm cuttings, cuttings maintain about 3 nodes. When cutting ears, pay attention to one knife in place to ensure smooth cutting and promote incision healing. In the incision can also be daubed with appropriate rooting agent, improve the rooting rate. Then control the good plant spacing cuttage to the seedbed, reasonable watering fertilization, keep the soil moist. Spring cuttings can be transplanted in autumn of the same year through normal management.

2. Seed reproduction

Seed reproduction requires harvesting seeds in the autumn of each year, mixing them with wet sand and storing them in a cool, ventilated place. Sowing is generally carried out around Qingming Festival every year. First, seeds should be taken out from the fruit and soaked in warm water of about 38 degrees for about 24 hours. Then stir it with plant ash to improve germination rate. Then timely sowing, sowing method should be based on drilling, control the seeding rate, prevent planting too dense. Water and fertilizer management should be done well in seedling stage to improve seedling survival rate. Generally, when seedlings grow to about 35 cm, they are planted.

3, layering propagation

Laying propagation is also a common method of propagation used by Vitex trifoliata. Usually layering time is generally around May every year, and cutting propagation is the same, first need to choose 1-2 years of strong branches. If the branches are longer, then a branch can be layered many times, every 45 cm or so buried in the soil 16 cm. But before layering, girdling should be done to the layering position, girdling to the xylem of the branch, smearing rooting agent to promote rooting. After pressing into the soil, irrigate enough water to compact the soil and prevent air leakage. When adventitious roots grow, they can be cut to form independent plants and transplanted for planting.

4. Plant division propagation

Although it is not commonly used to plant Vitex, it is also a method of reproduction. The use of ramet propagation, then, generally in April to July each year around. First, we need to select a strong growth, no pests and diseases with the well-developed plant as the mother plant. Then dig out the whole plant and evenly distribute it into 3-4 plants according to the distribution of roots. Pay attention to digging and planting, otherwise it is easy to lose nutrients and lead to the death of the whole plant. Planting is generally carried out in spring and autumn, control the row spacing, apply sufficient base fertilizer, and then water and press the soil.

The above is a simple introduction to the propagation method of Vitex trifoliata. Vitex trifoliata in the production process is generally based on cuttage propagation, because of the high survival rate of cuttage propagation, simple operation, suitable for large-scale planting.
