What are the anti-season fruits in summer?

Anti-seasonal fruits in summer: pineapple, jujube, cantaloupe, strawberry, etc.

Out-of-season fruit refers to the variety cultivated by high-tech means in greenhouse. The growth of out-of-season fruits does not rely on the use of hormones, but mainly changes the growth environment through greenhouse facilities, raises the room temperature, and advances the mature season of plants. If out-of-season fruits and vegetables are planted according to national quality standards, they can be technically guaranteed, and the quality is not much different from that of fruits produced in normal seasons. Special attention should be paid to the use of ripening agents or other hormone drugs to ripen and keep fresh anti-season fruits.
