What Are the Signs of an Aloe Vera Allergy?

Aloe (scientific name: Aloe vera (Haw.) Berg): It is a monocotyledonous plant family, Afuaceae (also known as Heliopsis, sage family), perennial green grass of the genus Aloe. Also known as Aloe vera ^[1] , Aloe vera, Aloe vera ^[2] , Aloe vera, Aloe vera, Aloe vera, etc. ^{[3] The} leaves are clustered, large and thick, pedunculate or born at the top of the stem, the leaves are often lanceolate or the leaves are short and wide, and the edges are spiked. The inflorescence is umbrella-shaped, racemous, spike-like, conical, etc., with red, yellow or red spots, six petals and six pistils. The base of the perianth is more connected to form a tube.

Evergreen, succulent herb. Stems are shorter.

1. Soil: Aloe has good water permeability and high organic matter content.

Aloe vera is native to tropical arid regions of Africa and is distributed almost all over the world. Wild aloe is found in India and Malaysia, on the African continent and in the tropics. It is cultivated in Fujian, Taiwan, Guangdong, Guangxi, Sichuan, Yunnan, and other places in China, and there are also wild aloes. There are at least 300 wild aloe species, including about 250 on the African continent.

Aloe loves to be warm and afraid of cold. When the temperature drops to 15 , it will stop growing, and when it drops below 0 , it will start to die. Therefore, the northern area must be planted in a greenhouse or indoor pot. Aloe is a tropical and subtropical happy light plant. It requires sufficient sunlight and air to grow. At the same time, aloe is a succulent plant in the tropical desert. Aloe is suitable for growing in sandy soils with strong air permeability and good water permeability. The amount of fertilizer required is not large. It is mainly organic fertilizer supplemented with trace element fertilizer.

I. Land Preparation

The soil is preferably fertile, loose, and well-drained sandy loam soil. The soil should be properly applied with manure or compost, and raked finely. General acres should be 1500-2000kg of rotten organic fertilizer, then 0.8-1m wide, depending on the terrain.. Soil that is too wet and sticky should not be planted.

Second, seedling cultivation

The shoots are bred in spring (March-April), or autumn and winter (September-November), and the seedlings that are tillered around each plant of Aloe will be dug out and cut off the underground stem connected to the mother plant. Colonization. Bud propagation is to cut 5-10 cm long new shoots from the leaf axils of the mother plant and place them in a cool place, 4-5 hours in summer and 1-2 days in winter, wait for the incision to dry slightly, and cut them into a seedbed with a shade on. Twenty days after rooting, the roots can be planted in the nursery for 2-3 months.

Third, colonization

It can be planted in spring (March-April) or autumn (September-November). Use 10-20cm high seedlings or interspersed seedlings, the planting distance is 50cm × 50cm or 40cm × 50cm, 2 rows per seed , 1 plant per hole. When planting, stretch the roots and compact the soil. If the soil is dry, the roots should be fixed in shallow water, and small branches should be used for temporary shading.

Field management

(1) Draining and Draining Water must be sprinkled when the weather is hot in summer to keep the soil moist. However, it should not be too humid, and the accumulated water should be excluded to avoid rotten roots.

(2) Weeding and weeding should be carried out during the weeding and growth of loosening soil. In the rainy season, weeds should be removed from the garden and piled up for fertilizer. In the dry season, weeds should cover the rhizosphere. Combine weeding or cultivating soil while weeding.

(3) Fertilization In order to promote the growth of plants, timely fertilization should be applied, with rotten organic fertilizers combined with chemical fertilizers. Fertilizer is applied 3-4 times a year, each time applying 4000-5000kg of cooked organic fertilizer per mu, 6kg of urea, and 50kg of superphosphate. ^[9]

The earliest record about aloe can be found in

There are about 500-600 species of aloe genus ^[19] , with various forms. A series of phylogenetic studies since 2010 removed some species from the broad Aloe genus and divided them into 5 new subgenus ( Aristaloe , Gonialoe , Aoidendron , Aloidendron , Aloiampelos , Folding fan aloe genus Kumara ^[20-21] ).

In the broad aloe genus before splitting, there are not only tree species such as Bifido aloe and Pearlans that can reach more than ten meters, but also small species such as the Jade Palace and Liuliji Peacock with a diameter of less than 10 cm. Have. In terms of leaf order, the leaves of most broad aloe species are alternate and arranged in rosettes; but the leaves of species such as Kumara spp. And Aloe calcairophila are opposite. The leaf texture of different kinds of aloes is different. Some aloe leaves are covered with delicate hoarfrost (Aloe vera, A. falcata ), some are smooth and powder-free, or have a rough texture (beautiful aloe) A. bellatula ). The leaf surface of some species is also covered with prominent white markings (Zebra aloe, Somali aloe, etc.) or longitudinal stripes (Aloe karasbergensis, etc.).

Aloe species also have abundant flower colors, with light red and true red being the most common. There are also yellow ( Aloe maculata , Aloe conifera ^[22], etc.) and white ( A. albiflora, calcium aloe A.). calcairophila, etc.); the inflorescences of some species also show a gradual color effect, such as aloe prickly spine, the flowers that have opened in the lower part of the inflorescence are yellow, and the flowers that have not opened in the upper part are red; There may also be differences in length and density of flower arrangements. In addition, there are some aloes with very special shapes, such as A. richardsia e with bulbs, A. tomentosa with inflorescences and green flowers.

Here are some of the more common species in artificial cultivation:

Sea tiger orchid

Aquilegia, also known as emerald green, is a hybrid of Aloe vera (now classified as Aloe ^[23] ) and Aloesuccotrina. ^[24] Easy to branch.

Hibiscus ^[25]

Aloe vera

Aloe vera is the third most widely distributed species in the genus Aloe and is endemic to sub-Saharan Africa. It is distributed in South Africa, Malawi, Mozambique, Zimbabwe and other countries. Because of its shrub-like plant type, it is often planted as a fence around the livestock pen in its place of origin. Cutting propagation is easier. ^[26]

Aloe vera ^[27]

Cape Aloe

Aloe vera plants can reach 2-3 meters in height and are usually unbranched. Old leaves will not fall off after withering, but will accumulate on the stem. The leaf thorns of the young plants were more significant than the adult plants. Plants of origin grow on rocky slopes above 1000 meters above sea level. ^[28]

Cape Aloe ^[29]

Sleepless City Aloe

Aloe vera, also known as Aloe Vera ^[22] , is a common hybrid of indoor decorative greenery, aloe vera and Aloe perfoliata . ^[30] Appearance combines the bright green leaf color of Aloe arborescens and the plant shape of Aloe vera.
