Propagation method of Panax notoginseng

[propagation method] Cuttage propagation is commonly used. The long stem segment of lOcm was selected in spring and autumn, and one or two leaves were inserted into the mixed medium of peat and sand. Put the countable branches in a pot and water them for the first time. Cover them with plastic film and place them in bright light, then spray fog on the leaves once or twice a day according to the dry and wet conditions. it is easy to rot if it is too wet, and it will take root for 3 weeks. Can also use water culture method, to ensure that the water temperature is higher than the air temperature, a few weeks later can take root.

[cultivation management] adequate light is required throughout the year, but to avoid direct sunlight in summer, it is appropriate to choose the south window of the bedroom.

The strong light will scorch the leaves, which will turn white at first and blacken soon. In a state of dehydration and dryness. On the contrary, the purple villi on its surface will fade when the light is not enough, and the leaves will become dim. The cultivated soil is generally mixed with garden soil, peat soil and rotten leaf soil. In the growing period to master the principle of watering rather wet than dry, once the soil is dry, the leaves will wilt and droop, at this time the need to immediately watering or spraying, in order to promote its recovery of firm growth. Do not spray water directly on the leaf surface, otherwise there will be color spots. The villi on the leaf surface accumulate water for a long time, and the leaves are easy to deteriorate and rot. Keep a moderate amount of water in winter, otherwise the branches will become soft and curved. Maintain a relative humidity of 50% to 60%. The growth period can be fertilized once a week, nitrogen fertilizer should not be too much, so as not to cause excessive growth, and leaf color desalination, multi-rotation phosphorus and potash fertilizer. Rotating fertilizer should pay attention to the first is that the fertilizer does not touch the leaves, and the other is to control the basin soil to dry properly after fertilization, so that the plant leaves are stout and strong, and the purple is thicker. When the flowers bloom in spring and summer, the flowers give off a strange smell, and the whole inflorescence can be cut off. Change the basin once a year. Due to the rapid growth of plants, attention should be paid to pruning and renewal, which can be integrated into spherical or cliff type, slope type and so on to add beauty. When overwintering, you can wrap the plant in paper, tie it up and cover it with a plastic bag and tie it to the mouth of the basin. Just put it indoors. The plant is perishable when exposed to cold.
