The South American esculenta, also known as the American phoenix, and the Mexican sycamore, scientific name: Zamiapumila L, is a large-scale rare ornamental plant of the genus Cycas, which has been introduced from the Americas in recent years. Compared with the cycads, their leaves and plant shapes are more bold and bold. They are popular from south to north and have become one of the popular indoor foliage plants. So how does a flower lover identify, breed, and conserve cycads in South America?
The iron trees in South America are mostly single stems, stem height 15 cm to 30 cm, few branches, sometimes clustered, thick cylindrical, dark brown leaf markings on the cylinder, perennial stems and stems are always young and young Sprouted; leaf is a large even-numbered pinnate leaf, clustered at the tip of the stem, leaf length 60 cm -120 cm, hard leathery, petiole length 15 cm -20 cm, sparsely hard little thorns; pinnate lobe 7 pairs - Twelve pairs, ovate ellipsoidal, unequal on both sides, base 2/3 entire, upper densely blunt serrated, apically obtuse acuminate, margin recurved, midrib absent, 40 prominent parallel veins visible on the dorsal surface of the leaf; male and female Plants, male inflorescence pine globose, 10 cm to 15 cm in length, female inflorescences like palmate.
Saplings can be used for the propagation of S. mellifera. Seeding can be mature seeds, wash off the aril after seeding, covering the thickness of 2 cm -3 cm, in the 30 °C -33 °C high temperature can germinate faster germination; summer should be given the necessary shade and water spray, winter Add moderately cold, about 3 years to 4 years for indoor pot planting. The cutting and sucking buds can be carried out between April and May in the spring after the house is out of the house. When cutting, the cuttings should be as small as possible and the stems should be as little as possible. The incision should be smeared with clean grass ash or sulphur powder. After the osmotic juice from the incision is dried, It is planted in a humified soil basin filled with more coarse sand. After watering, it is placed in the semi-shady area to root the roots. The temperature is preferably kept at 27°C to 30°C. The incision will heal quickly, and will be pumped out. New root.
South American cycad is native to Mexico, and its uniquely thick growing environmental conditions make it a meaty stout fibrous root system. Therefore, it is more tolerant to drought, but it requires the cultivation matrix to be loose and fertile. It is best suited for the growth of potted plants; the wells at the drain hole of the flowerpot should be well covered with tiles, and a thick layer of rough sand should be laid to facilitate the filtration of stagnant water in the basin. . It is like sunshine, especially suitable for warm and humid and well-ventilated environment, for this winter room temperature should not be lower than 0 °C, otherwise it will affect the normal growth of plants; summer scorching sun, high temperatures, should be placed half shade, Avoid direct sunlight, while keeping the basin soil moist, often spray water on the leaves and stems to maintain a relatively moist environment, in order to maintain the leaves green, vibrant. In the rainy season, the pots must be placed obliquely to prevent the water in the pot from causing rot. After entering the fall, the amount of water should be controlled. After the frost falls, it should be moved into the room as soon as possible. During the whole growing season, a pancake fertilizer can be applied once a month. In areas where the water alkali is heavy, a small amount of ferrous sulfate can be added to the pouring water to increase the acidity of the water and prevent physiological yellowing of the leaves.
