Rubber fig is wild at an altitude of 800-1500 meters in Yunnan, China. bhutan, Sikkim, Nepal, Ne India (Assam), Myanmar, Malaysia, Indonesia and Yunnan, China. It is cultivated all over the world.
Rubber fig is a tree, 20-30 meters high, DBH 25-40 cm; The bark is grayish white, smooth; It is epiphytic when young, branchlets stout. Leaves are thickly leathery, oblong to elliptic, 8-30 cm long and 7-10 cm wide, apex acute, base broadly cuneate, entire, surface dark green, bright, abaxially light green, lateral veins numerous, inconspicuous, displayed parallel; Rubber fig petiole is stout, 2-5 cm long; Stipules are membranous, dark red, up to 10 cm long, with annular scars after exfoliation.
Rubber fig is in pairs in leaf axils of deciduous branches, ovate-long elliptic, 10 mm long, 5 -- 8 mm in diam., yellow-green, basal bracts hooded, deciduous with a ring trace at base; Male flowers, gall flowers, female flowers in the inner wall of figs; Male flowers are stipe, scattered on the inner wall, perianth 4, ovate, stamen 1, anther ovoid, not with filaments; Rubber fig has 4 gall perianths, ovary smooth, ovoid, style subterminal, curved; Female flowers are sessile.
The achene is ovoid with a small tumor on the surface, style long, persistent, stigma swollen, subcephalic. Flowering period is in winter.
Rubber fig is produced in Bhutan, Sikkim, Nepal, North-East India (Assam), Myanmar, Malaysia (northern), Indonesia (Sumatra, Java).Wild in Yunnan, China (Ruili, Yingjiang, Lianshan, Longchuan) at 800-1500 m.
Rubber fig likes a warm and wet growing environment, and it is highly adaptable to light. The suitable temperature for growth is 15-35℃, not less than 5℃ in winter. Rubber fig likes fertile and moist acid soil, more water resistance wet, bogey drought.
Rubber fig is propagated by seedlings or cuttings, layering. The Fruit ripens in October, for the hidden head fruit, after collecting compost, into the cloth bag, knead in water, rinse out the seeds. The 1000-seed weight was about 0.3 g, and the germination rate was about 100. In some years the seeds do not germinate.
Production in the use of asexual propagation, Rubber fig cuttings in the spring after a steady rise in temperature, pruning young trees within 5 years of the young twig, with terminal cutting, the old branch is not easy to survive. Cut more milk, cut the branches, inserted in water for a few hours, wash the incision, and then inserted into the wet sand bed. Keep the light sparsely, spray moisture, about 25 days to the roots, about 2 months to the basin, the year as a small pot for viewing.
The high pressure propagation was carried out on the young shoots of 1 or 2 years. Wash the cut milk or wrapped with grass ash, ring peeled wrapped mud about half a month, Rubber fig tree root cut off the pot.
All over the world (including northern China), Rubber fig is often planted in greenhouses or indoors. It can also be potted for viewing or planted in gardens.
Rubber fig belongs to the hard Rubber category. In the tropical valleys from Tengchong in Yunnan, China to the north of Myanmar, it was used in the field, and abandoned after the introduction of Brazilian trifoliate rubber trees from Malaysia.
