Dragon fruit is native to Central and South America, is a set of edible ornamental as one of the tropical fruits, the 20th century 90's introduced to Taiwan, in recent years, has been introduced to Guangxi, Guangdong, Fujian, Guizhou, Yunnan, Hainan and other provinces and regions. We all know that dragon fruit belongs to the tropical fruits, but as the weather gradually become hot, now outside of Guangxi, Guangdong also began to plant a large number of dragon fruit, dragon fruit belongs to the more indebted to the plant, that is to say, its branches inserted as long as there is soil in the place will be able to survive.

The average annual temperature of dragon fruit planting area should not be less than 18 ℃, the average temperature in January should not be less than 8 ℃, long time less than 4 ℃ dragon fruit is prone to cold damage. In the North China dragon fruit greenhouse greenhouse, no heating and warming facilities, construction should be in accordance with the norms. To choose the material with good light ventilation, and keep the top clean and free of dirt.

Because dragon fruit has a high economic value as well as planting prospects, this southern tropical sun-loving crop began in China, Beijing, Shandong, Hebei, Liaoning, etc., the colder north, the use of greenhouse greenhouse warming technology for cultivation and planting, the northern planting of dragon fruit ordinary greenhouses can meet. As long as you can ensure that ordinary greenhouses in the winter, the temperature is not lower than 5 ℃, generally can be over.

The north can not only plant dragon fruit, and can be planted well, just a lower yield, can reach about 50% of the output of the South. To save labor and effort than planting seasonal vegetables, planted in Hebei Province, only ordinary greenhouse greenhouses, do not need to provide a heat source.

Because of the impact of the difference in temperature between the north and south, southern fruits to grow and fruit in the north must choose both cold and heat resistant fruits only. Orange is born in Huainan is orange, orange is born in Huabei is Hovenia, so it is not recommended that the introduction of southern fruits in the north. Now developed science and technology, the use of greenhouses and other facilities for protected planting, as long as the control of temperature, humidity and light and other necessary conditions for plant growth, whether it is anti-seasonal planting, or "anti-local" planting, can be realized.
