The leaves of copper coin grass are round and very cute, like the ancient copper coin, which means round and round, good luck, and the name is stained with the word "copper" and "money", which means natural and extraordinary: the family has copper money and rolling financial resources, so it is considered to be a symbol of wealth. So, do you know how to cultivate Pennisetum? Let's have a look
Hydroponic culture method of Herba Lysimachiae
1. The requirements for water quality of Herba Coptidis are not very strict. It can be cultured as long as tap water. Generally, when cultivating Herba Coptidis in summer, change the water every 3-4 days, and the water level is half of the bottle. In winter, the water is usually changed once a week. In winter, the transpiration of leaves is less, and 1 / 3 of the pots can be changed each time.
2. The requirement of light is also relatively strict. It has to accept more than four hours of sunlight every day, so that the copper coin can grow exuberant and green. Pennisetum is a sun loving plant, which can grow rapidly even without releasing fertilizer under sufficient sunlight. If the light is insufficient or kept in a dark room for a long time, the leaves of Pennisetum are easy to turn yellow and wither.
3. There is nothing particular about the fertilization of water cultured copperhead. If goldfish are cultured at home, you can directly replace the water for goldfish and pour it into the basin of copperhead.
4. The growth temperature of Pennisetum is better to be 16-24 ℃. If the temperature is too high or too low, it will inhibit its growth, and bacteria are more likely to sprout in high-temperature water.
5. The growth rate of Pennisetum is relatively fast. It can spread all over the water basin in a month. Therefore, when breeding it, we must properly prune and separate the Pennisetum, and transplant the too dense Pennisetum into other water basins, so as not to block the light of young leaves and affect the normal plant generation and metabolism.
Soil culture and breeding method of Pennisetum
1. First, check whether the vase for breeding Pennisetum has a drain hole. If so, plug the drain hole with something, or seal the drain hole with wax oil of candle.
2. When the pot for cultivating Herba Coptidis is finished, roll the soil into the flowerpot without large particles, and lay a thin layer, about 5cm thick. It is best to use ordinary garden soil, add some river sand, and add a small amount of organic fertilizer as the base fertilizer.
3. When the soil is paved, pour water over the soil. For another two days, let the rice and the flooded soil turn into shape, and then plant copper coin grass. If you sow the seeds of Pennisetum, you can directly sow the seeds of Pennisetum. If you plant by cutting, you can directly insert the roots of Pennisetum.
4. When everything is ready, put the Pennisetum in a warm and sunny place. After half a month, a pot of green Pennisetum will grow.
Breeding precautions of Pennisetum
(1) Copper coin grass, which likes sunshine and water, can be cultivated in water, soil and half water and half soil. Its leaves are round, very cute and very easy to raise. In short, you can do whatever you want. It doesn't compete for fertilizer, but it likes light and water. As long as there is enough light and water, it will be vibrant.
(2) Like warm and high temperature, 80% sunshine is appropriate. Insufficient light or excessive shading will lead to excessive growth of stems and yellowing and decay of leaves. It is necessary to use media with good water retention and often moisturize. Amphibious Pennisetum is common in aquatic ponds, wetlands and other spaces. Water pans and aquariums are also suitable.
(3) The leaf yellowing of Herba Coptidis sometimes occurs, which is mainly caused by the following reasons, which should be avoided as far as possible. First, the basin soil is too wet or dry for a long time, and it is not poured immediately when it is dry. Second, the root system has been frostbitten in winter. Third, the spring rush out of the room, copper coin grass can not adapt to the sudden climate. Fourth, it is placed in an environment with poor ventilation conditions for a long time. Fifth, the leaf surface is not washed by water for a long time, which accumulates dust and hinders photosynthesis.
(4) Generally, a large number of pruning is not required. When the leaves are too dense, the withered bottom leaves, outer old leaves and diseased leaves need to be removed in time to improve the lighting and ventilation conditions. In spring, when the pot is full of roots, change the pot and shape it by ramets. If the plant grows too high, it should be trimmed and pressed down to promote the germination of new branches at the base of stems and leaves.
(5) Copper coin grass does not need a large basin, but can also be planted in a larger bowl, and Narcissus basin can also be used. When planting, you can plant flat. Cover the rhizome so that you can't see it. Don't go too deep. Then put it in the half shade for a week. See the sun again when the new leaves grow.
(6) If it is found that new leaves generally turn yellow, compound fertilizer dominated by nitrogen fertilizer can be sprayed on the leaf surface. When there is water moss in the root system or water, it should be cleaned and changed immediately, otherwise it will be unfavorable to plant growth and affect the ornamental. Usually, pay more attention to whether the water in the container is sufficient to avoid drying out.
