Sisal fiber, also known as sisal, has the characteristics of long fiber, white color, tough texture, elasticity, strong pulling force and wear resistance. It can produce friction, acid and alkali resistance, corrosion resistance and slip resistance. A variety of quality, can be made into yarn, rope, polishing wheel, carpet, batt, sisal wallpaper, wire rope core, banknotes and handicrafts and other sisal products, and is widely used in fisheries, navigation, mining, transportation, oil and other industries

The leaves of sisal are rich in fiber, the fiber cells are long, the cell cavity is long and long, the wall is thick, and the fiber is long, the color is white, the texture is tough, elastic and strong. It can produce abrasion resistance and resistance. A wide range of products characterized by acid and alkali, corrosion resistance and slippage, and are widely used in fisheries, marine, industrial, mining, transportation, oil and other industries. It is resistant to friction and sea immersion and is used for rope making, netting, and weaving. Shortly chaotic fiber is used as floc pad and filler, and leaf juice is extracted from protease saponin. Sisal has the characteristics of warmth and drought tolerance, and is suitable for cultivation in tropical and subtropical areas. Sisal is native to Central America. The world's major producers of sisal are Brazil and Tanzania. China's sisal is mainly distributed in Leizhou Peninsula in Guangdong, parts of Guangxi and Hainan Island. Sisal is a characteristic crop in Zhanjiang City, and the industry formed is also a dominant industry. The sisal planting industry in Zhanjiang City began in the 1960s and was mainly produced and cultivated by the Zhanjiang Agricultural Reclamation Bureau (formerly the Guangdong Western Agricultural Reclamation Bureau). Because the fiber content of sisal is less than 5%, it must be processed first, and the fiber can be extracted to the market. Therefore, the sisal in the Zhanjiang area has paid attention to the processing of sisal from the beginning, and has been developing from the initial and intermediate processing to the deep processing of sisal products. Up to now, the research and development of sisal products has more than 10 series, hundreds of varieties, mainly including sisal fiber, sisal gauze, white brown rope, sisal carpet, polishing cloth, polishing wheel, sisal wallpaper, Steel cord core, etc.

Zhanjiang sisal fiber quality technical requirements (a) varieties. "East No. 1" sisal. (2) Site conditions. The soil in the protected area is basalt anvil red soil, the slope is less than 15°, the soil layer is more than 80cm deep, the organic matter content is more than 2%, the soil is loose and the drainage is good. (3) Cultivation management. 1. Seedling: Select “mother plant core propagation” or tissue culture and breeding seedlings, cultivated by planting nursery, seedling height 60cm to 70cm, plant weight 4kg or more. 2. Colonization: (1) Time: September to April of the following year. (2) Density: large row spacing 3.8m to 4m, small row spacing 1m to 1.2m, plant spacing 0.9m to 1m, planting more than 3750 per hectare. (3) Starting 畦: The flat 畦 is 20cm to 30cm high, the 畦 surface is 2m to 2.2m wide, and the 畦 surface is turtle-shaped. (4) Depth: The depth of the covering soil is not more than 2cm at the green and white junction. 3. Field management: (1) cultivating: Ma Tian is cultivated once a year, with a depth of 25cm to 35cm. (2) Fertilization: adopt nutritional nutrition formula and fertilize. (4) Harvesting. After the third year of planting, the cutting is carried out, and after harvesting once a year, it is generally harvested for 9 to 10 years. The leaves can be cut in all seasons; cutting is prohibited in rainy days, and leaves are cut from 55 to 60 after cutting leaves. (5) Fiber processing. Sisal leaf grading stacking → arranging → heading → uniform → using “Roby style” or “Krona type” scraping machine scraping → flushing → pressing water → wet lighting → drying → grading packing → acceptance Storage. (6) Quality characteristics. 1. Sensory characteristics: It is light green after processing, and gradually becomes milky white, the surface is smooth and shiny, the thickness is uniform and the toughness is strong. 2. Characteristic index: fiber length ≥ 85?, bundle fiber strength ≥ 830N, and impurity content ≤ 3.5%.
