Culture methods of Rabdosia angustifolia

Tongqian grass is a perennial herb of the coriander genus of Umbelliferae, with round leaves and exuberant vitality. the survival rate of soil culture or hydroponic culture is very high, and the underground rhizome grows rapidly, and each section can grow new roots and leaves. To summer and autumn, small yellow-green flowers can be produced, and the roots and leaves can be eaten as vegetables, with the effect of heat-clearing and dehumidification, diuresis and detoxification. Let's take a look at the breeding method of Codonopsis.

Propagation method of Rabdosia angustifolia

Rabdosia angustifolia is mainly propagated by split-plant method or cutting method, which is mostly carried out from March to May every year. It is easy to cultivate, keep the cultivated soil moist, and root in about 1-2 weeks. The sowing method can also be used to raise seedlings. The mixed matrix composed of rotten leaves, river mud and garden soil can be used to cultivate soil, and the proportion of them is 0.5 by volume.

Soil selection of Artemisia angustifolia

Artemisia angustifolia is not strict on soil, whether it is yellow loam, red loam or black loam, even in barren soil. But its drought resistance is not strong, so it is most suitable to grow in meticulous, sour, humid and low fertility loam. It is suitable for cultivation in the soil with loose fertility, large water absorption and good water retention, but also in moist river bank, swamp, grassland or fresh water with low hardness. The mixed proportion of rotten leaves, river mud and garden soil is 5:2:2.

Copper coin grass light requirements

Codonopsis lanceolata is shade-tolerant, preferably in half-day sunshine or shade, avoid strong direct sunlight, the more shady the environment is, the more likely it is to cause plant leaf rot. Rabdosia angustifolia does not win glory, but if you let it receive 4 hours of scattered light every day, or give it 8 hours of artificial light, it will make it grow better.

Temperature requirement of Rabdosia angustifolia

Rabdosia angustifolia likes warm and humid environment, but it is not cold-resistant. It grows well in the temperature of 10-25 ℃. When the temperature rises above 32 ℃ in summer, it will stop growing, and the temperature in winter should not be lower than 5 ℃.

Fertilization method of Rabdosia angustifolia

Rabdosia angustifolia has a high demand for fertilizer, and in the vigorous growth stage, it is topdressing every 2 to 3 weeks. If planted in pots or containers, a small amount of fertilizer is needed, such as quick-acting Fei Huabao No. 2, which can maintain fertilizer effect in water for a long time and ensure that the water quality is slightly acidic or neutral.

Watering method of Rabdosia angustifolia

Codonopsis lanceolata likes to grow in a humid environment. Because of its many leaves and large transpiration, it is necessary to spray water to the plants in summer to maintain high air humidity, and the leaves should be kept clean to facilitate photosynthesis. Winter basin soil to dry is appropriate, watering to follow the principle of wet rather than dry, avoid stagnant water, otherwise it is easy to rot the root. The tap water in the north should be kept in the sun for 1 or 2 days. Watering every 2 to 3 times during the growing period to keep the basin soil moist. The water is changed once in 7-10 days in spring and summer, and once every half month in autumn and winter. If aquaculture must change the water once a week and add a special nutrient solution for foliage plants. If you use soil culture, you must retain water for a long time. Water should be watered once every morning, the water should not be too sufficient, and the degree of water flow from the bottom hole should be taken as the degree to ensure that the basin soil is drenched.

Prevention and control of diseases and insect pests of Rabdosia angustifolia

There are very few diseases and insect pests in Tongqian grass. Strong growth adaptability, no need for deliberate nursing. After growing for a period of time, the copper grass will fill the whole container. Often spray water on the leaves to clean the leaves to keep them green and shiny. Attention should be paid to ventilation and ventilation after dense growth, otherwise the plant is prone to yellowing.

Notes on Codonopsis pilosula

1. Tongqian grass likes warm and high temperature, 80% sunshine is suitable, insufficient light or excessive shading will lead to excessive growth of stems, yellowing and decay of leaves, need to use a medium with good water retention, and often keep moist. Amphibious copper grass is often found in aquatic ponds, wetlands and other spaces, and aquariums and aquariums are also suitable.

2. Rabdosia angustifolia generally does not need a lot of pruning, and when the leaves are too dense, the withered bottom leaves and outer old leaves and diseased leaves should be removed in time to improve lighting and ventilation conditions. In spring, when the basin is full of roots, change the basin and reshape the ramet. If the growth of the plant is too high, it should be pruned and pressed to promote the germination of new branches at the base of the stem and leaf.

3. Tongqian grass likes sunlight and water, and can be cultivated in water, soil, and half-water and half-soil. The leaves are round, very lovely, and very easy to raise. In short, you can do whatever you want. It does not compete for fat, but it likes light and water. As long as there is enough light and water, it is full of life.

4. Copper grass does not need a large basin, it can also be planted in a relatively large bowl, and daffodils can also be planted. When planting can be flat planting, to cover the rhizome so that it is better not to see, do not be too deep. Then leave it in the semi-shade for a week and wait for the new leaves to grow and see the sun again.

5. The yellowing of leaves sometimes occurs in Rabdosia angustifolia, which is mainly caused by the following reasons, which should be avoided as far as possible. First, the basin soil has been too wet or too dry for a long time and has not been watered as soon as it is dry. Second, the root system has been frostbitten in winter. Third, the spring is eager to go out of the room, copper grass temporarily unable to adapt to the abrupt climate. Fourth, it is placed in the environment of poor ventilation for a long time. Fifth, the leaf surface is not cleaned with water for a long time, which accumulates dust and hinders photosynthesis.

6. If it is found that the new leaves are generally yellowing, compound fertilizer based on nitrogen fertilizer can be sprayed on the leaves. Wash and change water immediately when water moss appears in the root system or water, otherwise it is disadvantageous to the growth of the plant and affects the ornamental. Usually, we should pay more attention to whether the water in the container is sufficient or not, so as to avoid exhaustion.
