Dlium Duri bamboo (Bambusa blumeana)


Young reeds have a scattered white waxy coating and brown fur, eventually becoming shaggy and glossy green. The sections are 25-30 cm long and 5-10 cm in center line, 10-20 mm thick reed walls, sometimes almost solid at the base. The internode boundary protrudes with aerial roots.

The reed fronds fall out quickly, in the form of a wide triangle, 30 cm long, 22 cm wide, the lower part is short and narrow, more upward, gradually getting bigger and dull, like skin. The outer side is covered with hair, brown and easy to fall off.

The leaves of the reed are narrow lanceolate, 15 cm long, 1.5 cm wide, erect at the base and tip segments, flat on the middle segments, the edges curl inward, have hair that is scattered on the inside and bald on the outside.

The ears of the reed are small, broad ears that are sometimes wrinkled with hairs 5-15 mm long at the edges. The ligula is rigid, 3-5 mm high, highest in the middle and the outer side has stiff spongy hairs.



Leaf blade elongated lanceolate, 15-20 cm long, 1.5-2 cm wide, rounded base, narrow tapered tip, small midrib ears with a few straight hairs 1-3 mm long. Ligules are fragile, short and stringy.

Inflorescences in the form of grains on leafy branches or branches on leafless reeds with small groups of pseudospikelet on each internode and 1-5 cm apart. Spikelets are flat, up to 5 cm long, 2-3 empty glumas and 5-12 florets.

Duri bamboo grows to an elevation of 300 m, often in heavy and marginal soils, but not on salty soils, optimal pH 5-6.5. It grows well on hillsides, river banks and is more or less resistant to flooding.

The reed has a density of 500 kg/m3 at a moisture content of 15%. Without the preservation process, it can last 2-5 years under the roof, 1-3 years outdoors and 6 months of being submerged in sea water.

The thick reed is used as a building material, including for construction, support poles, parquet, parquet, furniture, kitchen utensils, toys, plaits and chopsticks. Reeds can also be processed into pulp which is good for making paper. The dry reed is used as firewood.

Shoots are eaten as a vegetable. Leaves and young twigs for animal feed. Bamboo clumps of thorns were also planted as anti-erosion, windbreaks, land boundary markers, living fences to protect gardens and as fences or fortifications in the past.
