Sisal is also known as pineapple hemp. Its shape is similar to that of pineapple, but it is much larger than pineapple. Sisal is a perennial tropical hard leaf fiber crop belonging to the agave family Agave. It is native to Mexico and is now widely cultivated in Africa, Latin America, Asia and more. Sisal is one of the world's largest and most extensive types of hard fibers. Its use is very wide, the following small series will come to you to introduce what sisal is, and the use of sisal and simple appreciation of sisal pictures.
Introduction of sisal
Sisal, also known as pineapple hemp, is a perennial plant belonging to the genus Agave, which belongs to the tropical hard leaf fiber crop. The stems of sisal are very thick and short, and the leaves are arranged in a rosette manner. Before the flowers bloom, sisal will grow 200-250 leaves. Its leaves are very straight, and the meat is thicker, it is sword-shaped. After being hoarfrost, the color will turn into dark blue green, and the length is generally 1.1.5m, the width of the middle is 10-15cm, and the surface is concave. The back is convex, the edges of the leaves are thorny, the color is reddish brown, and the length is 2-3 cm. Sisal is native to Mexico and is introduced and cultivated in South China and Southwest China.
Sisal growth habit
Sisal likes to grow in high-temperature and high-slope environment. The rainfall should be distributed very evenly, especially in the daytime, where the light, dry and high temperature are needed. At night, the foggy environment is the best, suitable for 27- Growing in an environment of 30 degrees Celsius, the maximum temperature should not exceed 40 degrees Celsius, the minimum temperature should not exceed 16 degrees Celsius, the annual average rainfall is 1200-1800mm, and the temperature difference between day and night should not exceed 7-10 degrees Celsius. The ability of sisal to adapt to the environment is very strong, relatively resistant to drought and drought, but it is afraid of cockroaches, strong growth ability, and a wide range of adaptation. It is suitable for planting in sandy soil with good drainage, looseness, low groundwater level and fertility. If it is often wet or poorly drained, it is not suitable for planting. Its cold tolerance is very low, often caused by cold. Physiological leaf spot disease is not conducive to the growth of sisal.
Use of sisal
The fiber in sisal has very good gloss, very strong elasticity, and its tensile force is also very strong. It also has light salt and alkali resistance and friction ability, and it is not stretchable even in a dry environment. Big features.
1. It was made into a cable by a naval ship, made into an inner layer of a tire on an airplane and a car, and a conveyor belt made of sisal was also used.
2. The rope core of the crane sling rope is also made of sisal fiber material.
3. After processing, sisal is mainly made into sisal yarn, sisal polishing wheel, sisal carpet, steel cord core, saponin, sisal wallpaper and so on.
4. The protective nets, tarpaulins, fishing nets and sacks used in large hydropower stations built in various regions of the country are made of sisal fiber.
5. The sisal residue of sisal is also widely used in crop fertilizers, agricultural by-products, livestock and poultry feed, etc., and sisal, pectin, alcohol and other products can be obtained from sisal sesame residue.
6. The use of sisal leaf juice can be refined into sisal saponin can be used to make the 53rd contraceptive.
7. The sisal head and relatively short fibers can be processed into fillers for insulating skin grafts and explosive products such as rayon, high-grade paper, brushes, and the like.
8. The flowers and stem juice of sisal can be brewed into wine and then made into various sugar foods.
The whole body of sisal is treasure. It not only has very good economic value, but also has good medicinal value and use value. It is a very precious plant and is planted in a large number in many areas.
