How does it look:
Bamboos are under shrubs to tall perennial, grasses;
Dwarf species are also cultivated for ornaments in pots and trays. Many species
gregariously flower and seed once and die soon after, vegetative state and incidence
of flowering vary from species to species.
How to grow:
Bamboos need warm temperature, though a range from -50
to 460C is suitable for successful growth and cultivation, and require
a rainfall of 75-500 cm or more.
Bamboos easily regenerate from seeds that germinate with the onset of monsoon.
In nursery they are planted both in pits (60cm x 30cm x 30cm) and contour trenches
at 3m x 3m, depending upon the slope. On slopes, it is recommended to stagger the
pits. In low-rainfall areas, they are planted in sunken pits for conservation of
moisture.

Though plantations are generally not given fertilizer, ammonium sulphate or calcium-ammonium
nitrate (200g) and superphosphate (200g per plant), if applied at the time of planting,
promotes development of roots; a similar dose is also recommended in the second
year in July. Combination of biofertilizer (Azotobacter) and inorganic fertilizer
yields significant height. About 3-5 weedings, and hoeing around plants, earthing
up, and mulching are done during the first three years of planting. Protection of
seedlings both in nursery and field from rats, hares and porcupines, goats and cattle
is essential; wild pigs eat the tender rhizomes. Constant cutting of the young plants
results in useless bushy growth. Many fungi and insects have been found attacking
various bamboos.
Uses:
-
Can be grown to stablise shifting sands, stream-banks, drainage channels, watersheds,
eroded riverbeds, on denuded wastelands, hill slopes, etc.; landslides can be controlled
by planting bamboos above and below hillside roads or steep embankments of roads.
Serves as a valuable windbreak. Extensive, shallow and fibrous root system also
improve fertility and texture of soil and conserves moisture. Recommended for agrisilviculture.
-
Timber :Easy availability, cheapness, strength, straightness, smoothness and lightness
combined with hardness, and facility and regularity with which they can be split
make bamboos the choice-timber, particularly for houses, huts,
etc. in the humid
tropics. Used in foundations, and for frames, floors, partition-walls, doors, windows,
ceiling and roof, ladders, buckets, vessels, gutters, water-conduits, etc.; can
be substituted for steel in concrete after a protective coating. Employed for various
types of boards, mats and veneers. Numerous articles of everyday use, such as textiles,
mats, screens, blinds, ropes, lashings and wickerwork are made from thin, tough
and pliable strips of immature culms. Bamboos from the basic raw material for paper
pulp and rayon.
-
Yields good firewood; charcoal from bamboo is reported to have more calorific value
than that from other woods; hence, used by goldsmiths. Recently, a liquid-fuel is
reported to have been prepared from the culms.
-
Young shoots are edible.
Where to sell:
-
Wood can be sold to furniture shops or to timber merchants for construction and
other purposes.
-
Wood can also be sold for firewood, especially to goldsmiths.
