Sisal is a single-cotyledon, early-growing, fleshy perennial herb native to tropical and subtropical regions of Central America with high temperature and low rainfall. It is a hard fiber with high economic value and is the most widely used in the world. Sisal production in China has developed rapidly in recent years and has become the first priority for farmers in southern China to become rich. 1. The cultivation technology of sisal is introduced as follows.

Planting and planting

 Sisal is commonly planted in Hilly and barren hills. Planting, in order to make full use of land and reasonable arrangements for the direction, according to the requirements of planting specifications, double-row planting general border 1.5 meters wide, 30 cm high, 3 meters from the border, 3.5 meters from the large row, 1 meter from the small row, 1 meter from the plant, each mu of 300 plants, from the border must open drainage color, to prevent waterlogging.

Two, apply sufficient base fertilizer

 The base fertilizer is mainly organic fertilizer, and 1500~3000 kg per mu. At the same time, 30 kg of phosphate fertilizer and 100 kg of lime were applied. The average length of the cave is 40 centimeters, 30 centimeters wide and 20 centimeters deep.

Three. Seedling selection

 Generally, seedlings without diseases and insect pests, tender and strong, non-destructive seedlings, seedling age more than one year, seedling height of about 60 cm, aging seedlings and susceptible seedlings can not be used as seedlings.

Four. Seedling treatment

 In planting, the seedlings should be classified according to size, the seedlings that do not meet the standards are eliminated, the seedlings to be cut off the old roots and leaves, cut the incision, and then planting. In case of planting in rainy days, it is necessary to disinfect 1% times of frost cream or 40% times of disease fruit 200 times to prevent disease.

Five. Planting time and method

 The planting time is usually 3-4 months. When planting, do not let the soil and fertilizer fall into the heart. Planting depth should not exceed the junction of MaoMu green and white.

Six, seedling management

 Sisal is a leaf fiber plant, should take the vegetative growth as the cultivation goal, therefore in the cultivation process should actively build sisal growth environment, cultivate huge root system, promote sisal stem and leaf thickening.

1. When sisal is just planted, because sisal leaves are few and can not be covered by the ground, it often leads to species of weeds clump, if not weeded in time, it is bound to affect the growth of sisal. Therefore, in order to weed the newly planted sisal in time, chemical herbicides can be used for weeding, but the herbicides can not be sprayed directly on the sisal to avoid the occurrence of pesticide damage.

2. fertilizer. The proportion of P and K fertilizer can be increased by applying organic fertilizer and a small amount of N fertilizer in order to promote the rapid growth and thicken the head of sisal. In general, sisal can be applied to nitrogen, phosphorus, potassium and dung water in 7~8 months. After the next year, 1500-3000 kg of high quality organic fertilizer, 15 kg of urea, 40 kg of phosphate, 40 kg of potassium, 100 kg of lime and 1 kg of borax were applied per mu. When applying fertilizer, the first-year-old sisal hemp was dug between two plants, the second-year-old sisal hemp was dug 40-45 cm at the side of two plants, the third-year-old sisal hemp was dug and applied at the side of another plant, then dug at the side of another plant in the row, and then moved another acupoint between the rows. In general, organic fertilizer and chemical fertilizer should be applied separately. Organic fertilizer should be applied once a year from March to April. Combining with weeding in winter and spring, organic fertilizer should be applied in combination with border cultivation. After covering soil, border surface should be higher than about 10 cm above the ground to prevent water and fertilizer volatilization. After growing for a period of time, sisal must be ploughed and loosened, because the root of sisal is composed of thick roots and various kinds of branched roots which grow out of the stem base and are concentrated in 30-40 cm deep soil. Therefore, in order to make its roots easy to grow and absorb nutrients, it is necessary to loosen the soil, prevent soil consolidation, and promote the growth of sisal, at least once a year in the middle tillage to loosen the soil, and before fertilization.

Seven. Field management

1. Qing Yuan. At the end of each December after the end of leaf cutting, immediately carry out a clear garden management, weeds and weeds in the garden to clean up.

2. cultivate and loosen soil. The soil of Macheng is easy to harden, so sisal can not absorb water and fertilizer. Therefore, after the end of the work of cutting the leaves and processing the fiber, the soil should be tilled and loosened in time, and after a period of weathering, fertilization and hemp residue should be combined to return to the field for soil cultivation.

3. sesame residues return to the fields. After sisal processing, the remaining hemp residue should be returned to the hemp field for organic fertilizer, open holes and apply, at the same time, 80-100 kg lime per mu, covering soil after application.

4. timely fertilization. Generally, 1500-2000 kg of organic fertilizer, 30 kg of urea, 30 kg of phosphorus, 40 kg of potassium, 100 kg of lime and 1 kg of borax are applied per mu annually.

Eight, reasonable leaf cutting

 After planting for more than 2 years, the effective leaves of the whole plant reach 100, and the first leaf cutting can be carried out with the leaf length above 90 cm, once a year, from September to December every year. The blade cutting intensity should be based on the maximum impeller of hemp stem. When cutting leaves, the blades with big head or below of hemp stem should be cut completely, and the blades above the big head should be kept completely. In leaf cutting, the hemp knife should be sharp, each leaf should be cut off once, the cutting edge should be smooth, hemp head should be complete, the petiole should not rupture, leaving the petiole 3 cm long, 25 kg per fold, for loading and unloading.
