Pineapple originated in tropical South America and spread all over Europe at the beginning of18th century. Pineapple has been introduced and cultivated in China for 300 years. Pineapple likes sunshine, drought resistance, high temperature and high humidity, and it likes cool and ventilation in summer. Pineapple is propagated by seed, asexual and ramet.

Pineapple tastes sweet and delicious and is rich in vitamins. Pineapple can be not only canned, but also eaten as a dish. Fruit juice can be used to make sugar, wine or vinegar, and the residue can be used as fertilizer or livestock feed. Moreover, the leaves are solid and durable, and farmers call them "Polo hemp". In the past, farmers used it to weave cloth, which is cool and durable, and can also be used as raw materials for making knots and making paper.

Growth environment of pineapple

Strong shade tolerance, like diffuse light, avoid direct light, but high yield and high quality still need adequate illumination. Pineapple is widely used in soil, but it is not suitable for neutral or alkaline soil, sticky or unstructured silt, and requires PH5-6.

The place where the annual rainfall is more than 1000- 1500mm and the precipitation time distribution is relatively uniform (the monthly rainfall is 100mm) is more suitable for pineapple growth. The groundwater level of 30-50 cm is beneficial to root growth.
