Alias: soap aloe, mosaic aloe
Family: Liliaceae
Species: Tropical plants with perennial fleshy pulp, leafy lanceolate, flowers yellowish or with red spots.
distributed:
It can be cultivated in open areas in parts of South China, Southwest, and East China, and other areas need greenhouse cultivation. Sandy loam with good drainage is required.
Origin:
Grass aloe is native to the tropical and subtropical deserts of Africa. The main climate in this region is high temperature, dryness, and low precipitation.
Growth habits:
Hi, warm, heat-resistant, cold-resistant, hi light, drought-resistant, impatient yin, avoid water and other habits.
The minimum temperature for growth is generally between 10°C and 12°C. Below 10°C, the growth basically stops. Between 0°C and 5°C, although no freezing injury occurs, the damage caused by cold damage on the aloe plants is also very obvious. In particular, the low temperature and cold damage that lasts for several days can make some of the leaves of Aloe vera grow weak and easy to infect various diseases. Soft rot occurred, and even the roots rotted, causing widespread death of aloe vera plants. When the temperature is lower than 0°C, lyophilization occurs inside cells of Aloe vera, completely destroying the protoplasm and cell structure of Aloe, causing damage, resulting in freezing injury and wilting of the affected parts.
The optimum temperature for grass aloe growth is 25°C-35°C, which is the best temperature for photosynthesis of aloe. Aloe vera has strong resistance to high temperature and adaptability. It occurs at a high temperature of 42°C in the high-temperature dry-hot valley of Yuanjiang, Yunnan, China, but aloe vera grows well there.
The grass and aloe are hi light. When the light is sufficient, the aloe plant grows vigorously, the leaves are hypertrophied, and the leaf color is dark green; when the light is insufficient, the plant performance is weak, the leaves are thin, the leaf meat is not fat, and the leaf color is light. However, too much light and too strong light will make Aloe Vera half dormant or stop growing, especially when the seedling leaves will become purple or dry wrinkles. Therefore, proper shading of newly planted aloe seedlings in production can shorten the slow seedling period and is beneficial to the growth of aloe seedling plants. At the same time, different wavelengths of light have different effects on the growth of aloe. Red light and orange light are beneficial to the synthesis of carbohydrates. Blue light is beneficial to the synthesis of proteins. Short-wave light, blue-violet light and ultraviolet light can inhibit stem growth. It is beneficial to the synthesis of vitamins. In the process of assimilation, Aloe vera absorbs red light and orange light, followed by yellow light, and blue-violet light has a lower efficiency. Therefore, aloe vera grown under scattered light produces slender metamorphosis.
Grass aloe vera has great patience and resistance to drought. For example, aloe vera is put up in a cool place. It does not supply water at all. Within six months, it is replanted in the ground to restore the normal supply of water. It can regenerate. leaf. However, maintaining a suitable water supply is still an indispensable basic condition for the normal growth and development of aloe. Different stages of growth, Aloe Vera's water requirements are not exactly the same. At the seedling stage, the Aloe leaf has less leaf area, less transpiration and less water, but the root system is relatively weak and has a shallow distribution in the soil. It is very sensitive to water changes and it is very important to keep the soil moist. In the adult planting stage, the water requirement for the aloe grows. When the root system is widely distributed, the ability to absorb water also increases. However, whether in the seedling stage or the adult stage of aloe, excessive soil moisture and even water accumulation are very unfavorable for the growth of aloe. Because too much water in the soil, will inevitably cause the lack of soil air, lightly make the root system of aloe damaged, while the weight of the whole aloe plant death.
Therefore, aloe vera, which grows in a rainy, wet season or when the drainage is poor, is prone to leaf atrophy, root rot, and even death. For aloe vera, the damage caused by too much water is far more than the damage caused by water shortages, ie drought. Therefore, there is a saying that aloe vera is not afraid of being wet, which is closely related to the origin of aloe vera in arid regions.
The leaf juice of Aloe barbadensis Aloe Vera is very creamy like soapy water; the leaves are thin and have a lot of patterns and spots. Saponin and aloe vera were not included in the pharmacopoeia, but they proved to be effective in treating rheumatism with topical application. Fresh leaf juice also has certain skin care effects.
The morphological feature of Saponaria aloe is that stem height is about 30cm, and the leaves are larger than wood aloe. The cold resistance is strong, and there are well-developed vinegrass stems underground, which can be used for breeding new plants.
There are many varieties of aloe-aloe, such as aloe vera, which is widely used for ornamental purposes. There are white streaks on the leaves, and the texture is clear. The leaves are wider and have higher ornamental value.
