PROBLEM TO BE SOLVED: To provide a method for cultivating mango by a heating installation, which can extend a harvesting and shipping period to a period between mid-September and February.SOLUTION: Fruit-bearing maternal branches are raised at night, an installation is heated in a closed state, and ventilation, etc. is performed in the daytime. A raising period is set to 50 to 200 days considering conditions such as temperature, humidity, nutrition, etc. suitable for growth of mango. During the period of time, raising of young shoots for raising the fruit-bearing maternal branches is adjusted once or thrice. During a rest period after then, the installation is kept in a water conservation state, and is heated, ventilated, or opened according to an ambient temperature. When the ambient temperature is 25°C or above, the installation is cooled so that it can be managed to be kept at 3-15°C at night and at 15-25°C in the daytime. A rest period after then is around two months, and after confirming the differentiation of flower buds, the rest period is completed according to a target harvesting time. Then, after a period of sprouting and flowering of the flower buds and a fruit growth period, the mango is harvested and shipped in a period from mid-September to February.SELECTED DRAWING: Figure 1 |
