Lai Vung is the kingdom of pink tangerine with the largest area, quantity is also the nation’s top. Gardening for over 30 years, Mr. Bich sees that selling tangerine in Tet will usually have to compete with other fruits like watermelon, mango, custard... With the product of about 50 tons/ha, tangerine is easy for a bumper crop but also easy to drop in price, that’s what farmers is worry about. The old farmer have a simple thought: “Tree cannot talk, human have to do it themselves”. First year, he tried on 2.000 m², covered with agricultural films, combined with the impact when cultivating has made the buds and branches to grow accordingly. Buds, branches this year will bring fruit next year. He prolongs the watering time; make the tree to bloom slower, fruit bearing time is slower than other gardens. His neighbor gardeners laugh at him, think that if he reversed the growing progress of the tree, it will die eventually. He doesn’t say anything but works. He himself recognizes that the Mekong Delta, start from September, flood and continuous rain can kill trees easily. The manure used will also be swept away. He uses agricultural films to cover all of the tangerine’s foot. Although agricultural films are more expensive compare to other films but it can release steam, so the tree won’t be affected much by weather.
