Introduction and knowledge popularization of Sedum succulent perennial grass. Evergreen grass is a general term for Sedum plants. There are only more than 40 original species, and the flowering period is generally from June to August every year, sharing the introduction and knowledge popularization of Sedum succulent evergreen grass.
Introduction and knowledge popularization of Cruciferae succulents; 1 Introduction of succulents.
Evergreen grass, because the fleshy leaves are arranged in a rosette shape, our common "Guanyin lotus" is also one of the evergreen grasses. Long grass is a succulent plant with a high reputation. Its plant shape is dignified, the leaf color of the atmosphere is changeable, and the purple of the tip is very unique. It is an excellent foliage variety among succulents, suitable for small and medium-sized potted plants, exquisite, peculiar and interesting for decorating dining tables, windowsills and balconies, and can be used to make various combined potted plants. In European and American countries, it is also often used to arrange rock gardens in greenhouses or plant them in cracks in stone walls for appreciation.
Perennial grass is a high mountain succulent plant, which likes sunshine, cool and dry environment and is suitable for all kinds of acidic, neutral and alkaline soils. In addition to proper shading in summer to avoid exposure to the hot sun, there should be plenty of sunshine in other seasons, less water in winter, and it can withstand the low temperature of -20℃. Plants are hot in summer and cold in winter, and they are dormant. The climate in spring and autumn is relatively cool, which is the main growth period and needs sufficient sunshine. If the sunshine is insufficient, the plant shape will be loose and compact, which will affect its beauty and appreciation. Plants growing in sunny places have plump leaves, compact plant types, beautiful leaves and look very beautiful.
Characteristics of alpine succulents
Succulents growing on high mountains have the following characteristics because of strong sunlight and ultraviolet rays, which can be used for identification.
1) The plant is rosette-shaped, low and with small leaves.
2) Plants are usually covered with various shapes and types of hair, or covered with powder or wax.
3) The photosynthetic parts of plants are generally low in meat quality, and most of them have strange shapes, flowers in full bloom and bright colors.
Differences between Eupatorium adenophorum and other succulents
In the 20th century, many growers became interested in this plant and planted it in their own gardens, which became a very popular ornamental plant and gradually spread from Europe to various countries. After World War II, Japan found that perennial grasses were quite chaotic and commercialized, and almost no original varieties were found, so it introduced a large number of original seeds from the country of origin again, and restored a considerable number of varieties, which made the curling plants once again attract everyone's attention and regain their ornamental charm.
According to records, Sichuan, Yunnan and Taiwan Province provinces are also the distribution areas of perennial herbs, which are mixed with low Sedum plants in the humid and warm mountainous areas. Now many of these varieties have been unable to be verified, and some varieties have been merged into Sedum or Lycopodium.
In plant morphology, they are very similar to many genera, and the main difference lies in their flowers. Generally, their flowers are terminal and will bloom only after the plants are clustered. After flowering, the old plant dies, and young plants grow from the base of the old plant to form new plants. Some species with no branches and larger plants are now merged into the genus Nelumbo. The classification of Eupatorium adenophorum is also controversial because it is easy to hybridize under natural and artificial conditions. Early succulents were divided into Sempervivum and Jovisbarba, and now they are generally divided into two groups. In recent years, scholars have been sorting out early varieties, and the confirmation of species of European origin makes the classification more scientific.
Maintenance of long grass
Master the principle of "no watering, no watering, no watering thoroughly" to avoid long-term accumulation of water, so as not to cause root rot, but not too dry, otherwise the plant will not die, but grow slowly or completely stagnate, and the fleshy leaves will be dull and lack vitality. Apply decomposed dilute liquid fertilizer or low nitrogen, high phosphorus and potassium compound fertilizer every 20 days or so. In winter, the temperature shall not be lower than 5℃ at night and 15℃ during the day. Plants can continue to grow, and they can be watered normally and fertilized properly. If watering is controlled to make plants dormant, they can also withstand the low temperature of 0℃.
Perennial grass is not heat-tolerant. After May, with the increase of temperature, plant growth gradually stopped and entered the summer dormancy period. It can be maintained under a shade shed or other places without direct sunlight. Pay attention to good ventilation, stop fertilization, control watering, and prevent rain, especially for a long time, to avoid plant rot caused by sweltering heat, humidity and soil water accumulation.
Turn the pan every 1~2 years in spring or autumn. When turning the pot, trim the root, cut the dead root or the elder root. Pot soil should be loose and fertile, with good drainage and ventilation. You can use half humus or peat soil, coarse sand or vermiculite, and mix a small amount of calcareous materials such as bone powder. Because the soil is wet, the newly planted plants don't need to be watered too much, and they are kept in a semi-dry state, which is conducive to the recovery of the root system.
Introduction and knowledge popularization of Sedum perennial succulents II. In order to make perennial grass easy to burst, it is necessary to do a good job in lighting, temperature, fertilization and changing pots. When cultivating, it should be placed in a place with sufficient sunshine conditions, and the optimum growth temperature should be kept at 18-26 degrees. During the growing period, pancake fertilizer and water can be applied once every half month, and the pot can be changed once every 1-2 years.
Potting method of explosive perennial grass
First of all, light
If long grass wants to achieve the purpose of pot explosion, it is necessary to ensure sufficient lighting conditions. For example, in spring and autumn, it can be placed in a place with sufficient sunshine conditions, and in summer, it can be placed in a cool and ventilated place indoors to avoid exposure. It can be placed in a warm and bright place in winter to keep healthy growth.
Second, the temperature
In order to make long grass bloom, it is necessary to ensure a warm environment, and the most suitable growth temperature is 18-26 degrees. Therefore, in hot summer, it is necessary to move to a cool place indoors and spray water to achieve the purpose of cooling down. Put it in a sunny place in winter. If the temperature is too low, you can cover it with plastic film to keep warm.
Third, fertilization.
If the long grass is to explode, it is necessary to apply fertilizer reasonably. During the growing period, pancake fertilizer can be applied once every half month and liquid fertilizer can be applied once every month. Note that when applying fertilizer, you must not apply concentrated fertilizer or raw fertilizer to avoid serious fertilizer damage and burning roots.
Fourth, change the pot
If you want the long grass to explode, you must change the pot well. Pots should be changed every 1-2 years. Because it likes to grow in humus soil or peat soil with good drainage, it can be mixed with humus soil, garden soil and river sand as matrix. Loosen the soil every once in a while to keep the soil breathable.
