Propagation method of ginseng fruit

There are two propagation methods of ginseng fruit.

First, seed reproduction, that is, sexual reproduction.

The second is cutting propagation, that is, asexual reproduction. Generally, we only use the method of cutting propagation, which is a simple method commonly used in ginseng fruit. That is, take the stem branch of ginseng, cut it into cuttings (cuttings), insert it in the soil, let it take root and sprout under suitable environmental conditions, and grow into a robust plant independently. Among them, the seedling bed cutting method is the easiest, and now we basically use nutrition plate cutting to raise seedlings.

The main results are as follows: 1. The selection of cutting stems and branches: fresh and tender stems and branches with good genetic characters and high yield plants should be selected, without disease and defect, in order to produce new roots and new buds. The length of the cuttings should be 10ml / 14cm. The cut cuttings should be inserted into the soil in time, otherwise they should be placed in a dark place or covered with a wet cloth to prevent dehydration.

2. The choice of cutting time: although ginseng fruit can be cut all the year round, the survival rate is high in spring and autumn. Cuttings in the middle of the day should be carried out after 4 p.m., in order to improve the survival rate. The suitable temperature for cutting can be carried out in the range of 15 ℃ and 30 min.

3. Cutting method: before cutting, in order to improve the survival rate, the cuttings can be soaked with growth hormone. When cutting, you should first make a seedling bed or prepare a seedling tray. When making a seedling bed, choose loose and fertile soil, make a bed 1-1.2 meters wide, apply 3-5 kilograms of rotten farm manure per square meter, and then make the bed after sprinkling pesticides that can kill underground pests. Smooth and fine the border surface, and then cut the cuttings straight into the soil, and then cover the soil to press so that the cuttings are exposed to the ground about 4cm, with a row spacing of about 10cm. The distance between plants is about 6 cm. After cutting, timely watering, the amount of water can be determined according to the specific situation.

4. Management after cutting: in late spring to summer and autumn, shading should be done and small water should be sprayed to prevent hot sun exposure. Shading tools can be removed after the seedlings grow new roots. If cutting in winter or when the temperature is low, in order to prevent frost injury, it should be carried out in a solar greenhouse or plastic greenhouse, and a small arch shed should be used to cover plastic film and grass curtains. Generally, cuttings take root a week after cutting. after the seedlings take root, they can apply rotten organic fertilizer or biogas liquid to promote new roots and new buds. Under the condition of suitable external environment, planting or seedling transplanting can be carried out about 40-45 days after cutting.
