Propagation is by seed Outdoor wood It grows well in almost any soil environmental factors that are suitable for planting soil. Like relatively fertile soil with organic matter , moisture. Like moderate humidity , light Alatus like lace-up area of shade trees. The sunlight (sun faintly) After long lace (1 year after alatus) requires full sun a day. Should gradually shade out the planting, maintenance , site selection and preparation and planting. Before seed germination, the seeds and cut the wings off before the material used for planting trees normally used sandy ground roasted and topped with a fungicide to prevent the mold damage seedlings to germinate new stacked wood grain. Cut wings out to the end of the root surface facing up (at the junction of the seeds with wings), the seeds to sink into the sand to the roots at the surface of the sand and sprinkle the top with the Louis coconut thin. watered every morning - cold enough moisture to germinate the seed sown, after 4-5 days, and then move the seed that grew into the bag, nursery next to the appropriate spacing and planting. Should be done during the rainy season from June spacing should be used. 4x4 m spacing, the survival rate is very high and the planting hole should thrive measures 30x30x30 cm hole should have an incoherent soil or organic fertilizers. The hole when planting should be holes to the surface, do not let water and pathogens of plants found in the Dipterocarpaceae including germs, Princess Mary, who's to blame, including: - the distance of the seeds and fungi that cause seed. deteriorated faster (There are about 50 species) stages of the seedling damping-off disease, including soil. Insect pests, including insects, seed drill drill seed weevil include leaf-eating insects, including a wild silk worms, worms, slugs, beetles dwarf golden shell boring insects, including stem-boring weevil insect shell drill with a drill stem length mirror. Growth rate Alatus wood is a slow-growth wood, aged about 14 years, with the growth of the average circumference of 82.84 cm has a volume of 3.83 kg / ha (7 t / ha) of storage in the wood. the enamel can be resistant to infestation and mold as well. Making it last a long time (over 10 years), the privatization because the wood is reddish-brown or gray-brown. This coarse, medium grain, sawing wood shavings decorated with ease. It defines the sawing beams made up siding slat roof joist floors, ceilings and furniture made of the use of the wood. Used in the construction of dwellings used for small boats dredge material used to make the ceiling joist is for Railway sleepers, etc. The use of the ecosystem. Temperature control in the air, the wind shadow moisture. Prevention of soil erosion, etc. The use of the Landscape Architecture. Growing road sides So beautiful The use of nutrition There are no direct benefits But that is beneficial to the growth of fungi, cork Riesa in tropical rain forest, which is called the mushroom tires, used as food. Taking advantage of the properties of a natural herbal King has a preamble on the year 2504 was concerned with the situation of rubber in over 40 years ago that "wood alatus in Thailand has been disconnected. Go up and made a number of products every year. It is to be feared that unless the maintenance and operation of the plant alatus up. The amount of rubber, it will diminish over time. It should not have to carry out research on the planting of rubber in order to put that knowledge to use in practice " alatus (Dipterocarpus alatus Roxb.) as a medicine timber of Asia. The large size Originated in Southeast Asia may have a height of 50 meters and a diameter at breast to 7 meters in Thailand in general. This is confirmed by the village, district, with the word "tire" in the country such as Tha Yang Yang Yang and Yang. The Wooden Virtually all parts can benefit both directly and indirectly.
