Agave Sisalana Seed

Sisal, also known as pineapple hemp, is a perennial tropical hard leaf fiber crop with stubby stems. [8] Leaves rosette arranged, straight, fleshy, sword-shaped, first frosted, then gradually shedding to a dark blue-green color; Panicles stout, yellow-green, with a strong odor; Capsule oblong.

Its origin in Mexico, is now mainly planted in Africa, Latin America, Asia and other places, is the world's largest amount, the most extensive range of a hard fiber.

Sisal fiber texture is tough, wear-resistant, salt-alkali resistance, corrosion resistance, widely used in transportation, fishery, petroleum, metallurgy and other industries, has important economic value. The world sisal import and export trade is growing, and China's current production of sisal fiber can not meet the domestic needs, and with the continuous increase of sisal fiber use, China is increasing the import volume of sisal fiber every year. At the same time, sisal has important medicinal value, cooling blood to stop bleeding; Detumescence and detoxification effect. It is mainly used for the treatment of tabes hemoptysis, epistaxis, hematochezia, dysentery, carbuncles, swollen poison, hemorrhoids and other symptoms.

Morphological characteristics

Leaf and stem

A perennial plant. The stem is stout and short. Leaves in a rosette arrangement, before flowering, a sisal plant usually produces about 200-250 leaves, straight, fleshy, sword shaped, initially frosted, then gradually shed and dark blue-green, usually 1-1.5 m long, up to 2 m long, 10-15 cm wide in the middle, concave surface, convex back, leaf margin without thorns or occasionally spiny, tip with a hard tip, spiny reddish-brown, 2-3 cm long.

Flowers

Panicles stout, up to 6 m tall; Yellow-green, with a strong smell; Pedicels 5-10 mm long; Perianth tube 1.5-2.5 cm long, perianth lobes ovate-lanceolate, 1.2-2 cm long, base 6-8 mm wide; Stamens 6, pedicled at base of perianth lobes, filaments yellow, 6-8 cm long, anthers 2.5 cm long, T-shaped; Ovary oblong, ca. 3 cm long, inferior, 3-locular, ovule numerous, style linear, 6-7 cm long, stigma slightly enlarged, 3-lobed. The capsule is rounded, about 6 cm long and 2-2.5 cm wide.

Fruit

The capsule is rounded, about 6 cm long and 2-2.5 cm wide.

Distribution range

Originally from Mexico; Introduction and cultivation in provinces and regions of South China and Southwest China.

Growth habit

High slope environment with high temperature and humidity and uniform rainfall, especially high temperature, dry and full sunshine during the day, and foggy and dewy climate at night are ideal. The temperature suitable 

for growth is 27~30℃, the upper limit temperature is 40℃, the lower limit temperature is 16℃, the temperature difference between day and night should not exceed 7~10℃, and the appropriate annual rainfall is 1200~1800mm. 

Its strong adaptability, poor tolerance, drought tolerance, fear of waterlogging, but strong growth, a wide range of adaptation, suitable for planting in loose, good drainage, low groundwater level and fertile sandy loam soil, 

poor drainage, often wet place is not suitable for planting. Low cold resistance, easy to occur physiological leaf spot.

Mode of reproduction

Seedling breeding

1. Breeding materials

There are bead buds, sucking buds and walking stems. Bead buds should be selected as normal flowering, robust, no thorns, no pests and diseases. Can also use the field strong suction bud.

2. Breeding methods

There are two main methods: core drilling method and core stripping method.

Core drilling method refers to the selection of hemp seedlings about 35~40cm high and 25~30 leaves in the breeding nursery, the heart leaves are pulled out by hand, and the flat head drill is inserted into the shaft, deep to 

the hard part, rotating several times to destroy the growth point and promote the initiation of axillary buds.

Core stripping method refers to the selection of hemp seedlings with a height of about 35~40cm and 25~30 leaves in the breeding nursery for core drilling, after 20~30d, strip the lower leaves 7~8 pieces, and pay attention to 

not stripping the bud point.

3. Choice of nursery land

Choose fertile soil, loose soil, good drainage, full sunshine, close to the water source of the land as nursery nursery, generally not suitable for continuous cropping.

4. Establishment and management of breeding nurseries

Select 25~30cm high, hemp head stem held more than 8cm, tender and strong, no pests and diseases as the mother plant: base fertilizer to organic fertilizer. With phosphorus, potassium, lime and other applications; Seedling 

bed row spacing 0.5m×0.5m or 0.5m×0.4m; Keep the seedbeds free of weeds and fertilize them once a month. After picking seedlings once, topdressing (decomposed dilute manure water plus urea) once; General seedling height 

20~25cm when picking seedlings. When picking seedlings, do not damage the mother plant and young seedlings, and leave 1cm at the base of the seedlings to facilitate continued emergence.

Planting procedure

1. Prepare the seeds

Prepare sisal seeds in advance, to choose high-quality and full sisal seeds, the freshness of the seeds is high, and the survival rate of such seeds is higher. The sisal plant is sifted through, removing bad and incomplete seeds and leaving good seeds for sowing.

2. Raise seedlings

Sisal like high temperature and humid environment, in the case of suitable climate can grow seedlings in the open, if the climate is not suitable, you need to grow seedlings in the greenhouse, the specific we can according to the local situation.

3. Colonization

After the completion of seedlings can be planted, at this time sisal seedling height above 50 cm, leaves 20-25 pieces, the spacing of colonization should be appropriate, the subsequent growth process to cut off dead branches and leaves, flowers in time to cut off the peduncle.

4. Management

Sisal daily management should pay attention to proper soil cultivation, fertilization, in order to promote the growth of plants. Sisal's own growth is relatively neat, do not need too much pruning, each time after the collection of leaves to strengthen maintenance, so that the plant quickly return to growth.

5. Pests and diseases

The most common diseases of sisal are spot disease and leaf spot disease. In addition to daily management, we should often check the condition of the plants. When the disease occurs, 70% methyltopsin wettable powder 1000 times liquid spray the plants. Sisal pests can be sprayed with 40% Dimethoate emulsifiable oil 1000 times liquid to kill.
