Binh Thuan is known as the "capital" of dragon fruit. The area of dragon fruit cultivation in the whole province of Binh Thuan is about 26,550 hectares, with an output of 325,000 tons/year.
Since the two highways: Phan Thiet - Dau Giay and Vinh Hao - Phan Thiet passing through Binh Thuan, many people traveling on these two highways at night, when gardeners turn on lights to stimulate dragon fruit flowering, will be able to admire the brightly lit dragon fruit gardens along the highway.
However, many people wonder why some dragon fruit gardens are brightly lit with yellow lights, while others are lit with pink lights? Is pink lighting necessary for red-fleshed dragon fruit?
Lighting the dragon fruit tree at night is to promote the dragon fruit tree to flower. Because dragon fruit is a sun-loving plant and sunlight is limited each day. Therefore, lighting the dragon fruit tree at night increases the heat, making the dragon fruit tree grow well and flower.
According to gardeners, choosing the color of the lamp is the choice of the gardener. It depends on experience and calculation of cost, economy and efficiency of the lamp. It is known that the pink lamp is a 5W LED lamp, and the yellow lamp is a 9W LED lamp.
According to the Farmers' Association of Binh Thuan province, after a period of coordination to implement a pilot model of using specialized 5W LED lights to stimulate dragon fruit flowering in the area, the results showed that 5W LED lights (red light) save electricity costs and reduce total production costs compared to 9W LED bulbs (yellow light).
Therefore, the color of the lights is the choice of the garden owner to achieve economic efficiency, fruit yield and reduce production costs.
Due to the high value of the light bulbs and wires used to light dragon fruit in gardens, there has recently been a case of theft of electric wires and light bulbs used to light dragon fruit. Therefore, garden owners often increase their garden supervision. In addition, there is a service of renting light bulbs and wires used to light dragon fruit to help gardeners reduce investment costs.
