Propagation methods of Vitex mandshurica

Vitex mandshurica is the fruit of Vitex mandshurica plant, which has high medicinal value. It is mainly distributed in the waterfront and has a large planting area in China's coastal provinces. Bauhinia can be used except for those with weak stomach and weak body. It has the effects of Xinneng dispelling wind, slightly cold and clearing heat. So how do we breed when we plant bauhinia? The following editor brings you the breeding method of Vitex chinensis. Let's have a look!

1. Cuttage propagation

The time of cutting propagation of Vitex mandshurica is usually in spring and autumn, but it is usually suitable in spring. First of all, choose 1-2-year-old stout branches, cut them into cuttings of about 25 cm, and keep the cuttings with about 3 nodes. When cutting cuttings, we should pay attention to a knife in place to ensure that the cut is smooth and promote the healing of the incision. An appropriate amount of rooting agent can also be applied at the cut to improve the rooting rate. Then control the row spacing cutting into the seedling bed, reasonable watering and fertilization to keep the soil moist. Spring cuttings can be transplanted in autumn of the same year through normal management.

2. Seed propagation

Seed reproduction needs to be harvested every autumn, mixed with wet sand and stored in a cool and ventilated place. Generally, before and after Ching Ming Festival is sowed every year, the seeds need to be taken out of the fruit and soaked in warm water of about 38 degrees for about 24 hours. Then mix with plant ash to improve the germination rate. When sowing at the right time, the sowing method should be mainly strip sowing, and the sowing amount should be controlled to prevent planting from being too dense. In the seedling stage, we should do a good job in water and fertilizer management to improve the survival rate of seedlings. It is generally planted when the seedlings grow to about 35 centimeters.

3. Striping propagation

Striping propagation is also a commonly used method of propagation of bauhinia. Usually the time of striping is about May every year, and like cutting propagation, we first need to choose 1-2-year-old sturdy branches. If the branch is longer, then a branch can be pressed several times, burying it into the soil every 45 cm or so. However, it is necessary to do ring peeling work on the pressing part before pressing, peeling to the xylem of the branches, smearing rooting agents to promote rooting. After pressing into the soil, pour enough water to tighten the soil to prevent air leakage. When adventitious roots are grown, they can be cut to form independent plants and transplant.

4. Ramet propagation

Although planting bauhinia is not commonly used for ramet propagation, it is also a method of reproduction. If ramet propagation is used, it is usually carried out around April to July every year. First of all, we should choose a plant with strong growth, no disease and insect pests and developed with the group as the mother plant. Then the whole plant was dug up and evenly distributed into 3-4 plants according to the distribution of the roots. Pay attention to digging and planting, otherwise it is easy to lose nutrition and lead to the death of the whole plant. Planting is generally carried out in spring and autumn, controlling the row spacing, applying sufficient base fertilizer, and then watering and pressing the soil.

This is a brief introduction to the breeding methods of Vitex mandshurica. In the process of production, Vitex mandshurica is mainly propagated by cutting, because of its high survival rate and simple operation, it is suitable for large-scale planting. That's all for today's introduction, this article is for reference only. I hope I can help you all.
