Eucalyptus saligna

Viable seeds / kg (approx.): 210,000

Minimum purchase: 25 g




Description



E. saligna is native to
Australia, but it has been successfully introduced to many tropical sites. It
can reach 40 to 55 m in height and 1.2 to 2 m in diameter (DBH). The trunk is usually straight and of good form, and it sheds its branches readily to leave a clean stem.



Uses



The wood is resistant,
hard and heavy, with high natural durability and easy to work. It is reddish,
rough texture, straight grain and difficult to dry, with a tendency to crack
after drying. It is used for heavy construction, structural timber, veneers, plywood,
particle board, fiber, transmission poles, fence posts, firewood and high
quality coal.



Environmental conditions



This species occurs
naturally from sea level to 1,100 masl, although it has been planted
successfully up to 2,300 masl, with mean annual rainfall of 900 to 4400 mm and mean
annual temperatures of 15 to 26 ° C.



Soils



It requires deep soils,
well drained, humid, of medium high fertility. It does not thrive in compacted
and flooded soils without adequate preparation, or where there are strong
winds.



Seeds and nursery



It does not require pre-germination treatments. Due to the small size of
the seeds, germinators should be used, with a loose substrate such as river sand,
well washed and disinfected, in which the seed is placed superficially.
Germination occurs in a period of 5-12 days, reaching conditions for transplanting
1-2 weeks after germination. The root is usually very long, so it must be
pruned to about 3 cm in length. When transplanting, be sure to make a hole deep
enough in the substrate to avoid curving up of the roots. Shade should be
provided for the first 2-3 weeks after transplanting, for instance using shade
clothing (saran) 50%. The plants will be ready
for field planting after 3 - 4 months or when they have a height of 15 to 20
cm. A couple of weeks before planting out in the field it is recommended
to reduce watering to stimulate the lignification of the stems.



Growth



E. saligna is a very fast growing species, even in adverse soil conditions. In
different sites in Central America, increments of 3.9 - 4.3 m / year in height
and 3.6 to 4.1 cm / year in diameter have been obtained. The estimated rotation
is 15 - 25 years for the production of wood for sawing, and 6-10 years for the
production of firewood, poles and pulp. For
sawmill production, initial spacing should be at least 3 x 3 m. For production
of firewood, posts or tutors, high densities (up to 5000 trees / ha or more)
are used, generally with spacing arrangements from 1 x 1 m to 2.5 x 3 m.
The species sprouts well once cut, so that shoot management can be used as a
method for renewal of plantations.
