Swordsman (academic name: agave sisalana perr. Ex engelm.) is also known as pineapple, a tequila plant that has grown over many years in the tropical hard-leaf fibs。
In mexico,1 originally produced, mainly in africa, latin america and asia, the world's largest and most extensive hard fibre. The fretilin is robust and is widely used in a variety of industries, including transport. Short hair. The leaves are in the form of a loaf, straight, white frost at first, and then they fall down into deep blue and green, dents on the surface, cones on the back, and no thorns in the leaves. Flowers are stylished by pellets of eggs, born on the basis of fragrances, filamental yellow and thong-shaped; and sub-houses with round shapes, most embryos, dysenteral lines, round shapes。
In 1963, the shane gol and the wang dong-taos had a great discovery. - one of tanzania's saman species is suitable for cultivation in china。
Form characteristics
Growing plants. Short hair. Before flowering, a sword normally produces about 200-250 leaves, straight leaves, flesh, sword shapes, initially frosted, then gradually fall down and turn deep blue green, usually 1-1. 5 metres long, up to 2 metres wide, up to 10-15 centimetres wide in the centre, dents on the surface, bumps on the back, no thorns on the edge of the leaf, one hard-stabbing, red brown, 2-3 centimetres long. The cones are thick in length and height of up to 6 metres; they are yellow and green and have a strong odour of 4; they have an infarction length of 5-10 mm; they have a pipe length of 1. 5-2. 5 cm, they have a fibrous egg-shaped pinhead of 1. 2-2 cm, they have a base width of 6-8 mm; they are born in fragrances of 6-8 cm, they are in fragrance, they are in fragrance, they are in vegetated yellow, they are 2. 5 cm, they are in typographical shape; and they are birch, about 3 cm long, lower, 3 room, embryos are majority, they are in plume form, they are 6-7 cm, they have a slightly larger column, and they are fractured. Zirconium fruit with a long circle of about 6 cm long and 2 - 2. 5 cm wide。
Growing habits
High slopes with high temperatures, wetness and even rainfall, especially high daytime temperatures, dryness, adequate sunlight, and the most ideal weather in the evenings. The suitable temperature is 27-30°c, the upper limit 40°c, the lower limit 16°c, the difference between day and night should not exceed 7-10°c, and the appropriate annual rainfall is 1,200 ~ 1800 mm. They are more resilient, infertile, drought-resistant and flood-prone, but they are growing with a high growth capacity and wide range of adaptations. They can be grown in sandy, sandy land that is loose, well drained, low and fertile in groundwater, and in poorly drained, often humid areas. Low resistance to cold and prone to physico-folic diseases。
Distribution
Born in mexico; in the south and south-west provinces of china。
Cultivation
Cultivation methods
Cultivation
1. Reproduction materials
And beads, sprouts, and runners. Plumbs shall be selected for normal flowering, robust, thorn-free, pest-free. It is also possible to use the strong sprouts of daejeon。
2. Reproduction methods
There are mainly two methods of drilling and cutting leaves。
The core method is the selection of seedlings of about 35-40 cm tall and 25-30 foliages in breeding nurseries, the extraction of the heart leaf by hand, the drilling of flat head into the axles, deep into the hard, several rotations, the destruction of growth points, and the emergence of breaths。
Leaching means drilling around 35-40 cm tall and 25-30 foliages of seedlings in breeding nurseries. After 20-30d, seven-eight foliages are removed from the lower lobe, with care not to remove the buds。
