Many fruit trees bear alum and salinity with high economic efficiency

After more than 4 years of research, Can Tho University scientists have succeeded in grafting up grapefruit roots, indigenous oranges, creating varieties suitable for heavy alum soil.

Biotechnology Professor Nguyen Bao Toan, Head of Can Tho University laboratory said:

'The Mekong Delta has many kinds of fruit trees growing around the house, the ditches suffer from alum, drought and salinity are very high but their fruits are of poor quality and economic efficiency is not high. We have studied transplanting of fruit trees to native plants that have created many new trees to adapt to the environment, for high economic efficiency '.

After more than 4 years of research, Can Tho University scientists have succeeded in grafting up grapefruit roots, indigenous oranges, creating varieties suitable for heavy alum soil.

Such a land in Long Phu commune (Long My, Hau Giang) now has many orchards of rootstock pomelo Nam Roi, oranges for delicious fruits.

Scientists at Can Tho University found ' bamboo ', oranges and mandarins growing in Chau Doc mountains with high drought tolerance, using it as a rootstock for oranges, tangerines and grapefruit. Currently, a large number of orange, tangerine and grapefruit trees have a rootstock that is grown on high drought-resistant hills.

From 2004 to now, scientists at Can Tho University have also discovered that the ' sarcophagus ' is saline tolerant to growth in Tra Vinh and Soc Trang. It is used as a rootstock for oranges, tangerines and grapefruit, which have created high economic efficiency in coastal saline areas of the Mekong Delta.
