The inflorescence is pulled out from the leaves, shaped like a pine cone, and grows when bearing fruit; Bracts are green at the base, reddish at the upper part and triangular-ovate; Sepals are broadly ovoid, fleshy and reddish at the top; Petals are oval, pointed, about 2 cm long, purple in the upper part and white in the lower part. The flowering period is from summer to winter.
Pineapple is native to the dry tropical mountainous areas of Brazil, Argentina and Paraguay. Because of its good storage and transportation resistance, pineapple buds were quickly introduced into tropical and subtropical regions of the world in a short time.
Pineapple cultivation in China is mainly concentrated in Taiwan Province, Guangdong, Guangxi, Fujian, Hainan and other provinces, with a small amount of cultivation in Yunnan and southern Guizhou, which has a history of more than 400 years. The main pineapple producing areas in Taiwan Province Province are Tainan, Taichung and Kaohsiung. Guangdong province has a large pineapple planting area and a large output.
Extended data:
Pineapple is native to tropical high-temperature and arid areas in South America, with mild nature. It can grow at the annual average temperature of 24-27℃ (the most suitable growth range is 15-40℃, but it grows slowly below 15℃, and basically stops growing below 10℃, and 5℃ is the critical temperature of chilling injury.
Pineapple has extensive adaptability to soil. Sandy loam or mountain red soil with shallow roots and aerobic, loose, well-drained and rich in organic matter, with a pH value of 5~5.5, is better, while poor, sticky and poorly drained soil and high groundwater level are not conducive to pineapple growth.
Pineapple is short, and the direct impact of wind disaster is small. Winds below level 3 are also good for breathing. Strong typhoons and strong winds will also blow down plants, break fruit stalks and distort leaves, affecting normal growth and development; The cold wind and rain in winter will cause people to rot.
