PENGARUH RUANG TUMBUH TERHADAP RESPON PERTUMBUHAN DAN PERKEMBANGAN TANAMAN MERANTI MERAH (Shorea pauciflora King.) DAN NYAWAI (Ficus variegata Blum.)
Abstract: The results showed
that the arrangement of growing space T1, T2 and T1 + T2 combinations, each of
which can increase the high growth 143.7% (172.30 cm), 37.1% (96.9 cm) and
105.7 % (145.40 cm), stem diameter width of 110.0% (18.30 mm), 34.7% (11.0 mm)
and 123.3% (18.29 mm) and 142.6% canopy ( 181, 45 cm), 36.9% (102.4 cm) and
106.6% (154.55 cm) than the control (T0) to plant the meranti merah (Shorea
stenoptera Burk.). The space to grow this type of Meranti merah (Shorea
stenoptera King) Age 5 years have shown that treatment with a combination of
vertical and horizontal (T3) showed best in order to enhance the growth of stem
diameter, equal 118.2% (3.0 cm) than in the control (T0). The height of the
plants in T1 and T2, and T3 have shown increased 55.6% growth, respectively at
133.3% and 66.7% compared to control (T0). Bandwidth test vintage Meranti merah
(Shorea selanica Bl) cultivation of clippings from shoots in the treatment of
broad lines of 2 m, 3 m and 4 m is still the original data (0 months) show a consistent
altitude is 45.5 cm, 6 cm and 46, 47.7 cm. Growing requirements nyawai (Ficus
variegata Blum.) In KHDTK Kintap in some areas with B-type, red soil climate
yellow podzólicos (FA), the texture of sandy clay with drain if - so, solum
shallow soil (< 50 cm) of depth (> 1 m), the pH of 4 to 5.5 soil with an
elevation of 50 metres on the level of the sea - 433 meters of altitude in the
Valley and the slope (flat topography - tracks (> 45%) on the State of the
type of vegetation in the mix) rare density (natural vegetation). Tree species
associated with nyawai (Duabanga moluccana), Macaranga spp, Shorea spp, Trema
sp., and Anthocephalus cadamba. Related plant species are under cylindica
grass, vines, shrubs, narrow leaved (leaves ribbon), among others, ferns,
nettles and some types of grass.
