Tamarind is a specialty of Fujian, Guangdong, Guangxi, Sichuan, Yunnan, Hainan, Taiwan and other places.

Tamarind, also known as sour bean, tamarind, sour plum, etc., is a plant of the genus Tamarind in the Leguminosae family. It is mainly distributed in the Jinsha River, Nujiang River, Yuanjiang dry and hot valleys in Yunnan and Xishuangbanna, with an altitude of 50 to 1350 meters. The heat of rice is good.

The sour bean pods are fleshy and grey-brown, with thin and crisp outer skin. The flesh is reddish-brown when ripe and tastes sweet and sour, hence the name "tamarind". The pulp has two types: sour and sweet. The sweet ones are also called sweet corners by the common people. Tamarind is a plant that likes sunshine. Its biological habits like light and heat. It can adapt to arid and hot environments. It mainly grows in tropical and subtropical areas and can adapt to monsoon climate.

Cultivation technology

Tamarind is highly adaptable and can be planted on flat land, mountains, roadsides, and in front of and behind houses. It can grow normally in areas with poor sandy red loam or vertisol soil with a little management. However, large-area planting should be planned rationally, mountainous areas should be reclaimed at the same height, and areas with severe soil erosion should be no-till, and Yulinkeng large pond rainwater collection technology should be used.

Since sour beans are typical positive plants, plant growth, fruit development, and maturity are all directly related to light. However, the density is too high, which affects the ventilation and light transmission of the plants, and the growth and development of the inner fruit is poor. In addition, the degraded slopes do not have any watering conditions, and there is a serious lack of nutrients and water for plant growth, resulting in thin plants, premature tree aging, and reduced fruit quality, which will lead to a batch of fruit pods shriveling and reducing the harvest rate.
