Narra (Pterocarpus indicus) is mainly distributed in China, Taiwan, Guangdong and Yunnan (southern). It is also found in India, Philippines, Indonesia and Myanmar.
In sloping forests or cultivated in gardens. Narra trees have strong adaptability to the environment, not demanding soil, gravel soil, coastal sand soil, and even containing a certain amount of salt soil can grow well. Its root system developed, with nodules, can nitrogen fixation; Narra likes strong light, and has fast growth and strong regeneration.
1. Soil: Narra tree (Pterocarpus indicus) does not have high requirements for soil. It can grow normally in sandy soil or gravel soil, and it has strong adaptability to the environment.
2. Light: It likes sunshine. In the environment of sunlight will grow faster, and can not let it grow in a dark place for a long time, which will affect its normal growth.
3. Watering: Water the right amount to the Narra tree, not too much watering, generally 2-3 days watering once, watering to be watered, the soil to be in a moist state can be. Don't leave waterlogging for a long time.
Sowing propagation: Sowing propagation roots will be more developed, the ability to resist the wind will be strong, branches and leaves will be more lush.
2. Cuttage propagation: The robust branches are cut and inserted into the seedbed. The cutting operation is very convenient, but the wind resistance is very weak.
In Narra (Pterocarpus indicus) seedlings, it will appear nevus or anthrax, will harm the leaves and branches, etc.. I is found that it is suffering from disease after the timely removal of sick branches and leaves, and burned, and then sprayed with agents, so as not to cause secondary infection.
Narra canopy extension, dark green, beautiful, is an excellent Garden greening tree species.
Narra wood is hard and dense with red hearthwood, making it an excellent wood for construction, Musical Instruments and furniture.
Resin and wood are used for medicinal purposes.
