2, China's pineapple cultivation is mainly concentrated in Taiwan, Guangdong, Guangxi, Fujian, Hainan and other provinces, Yunnan, southern Guizhou also has a small amount of cultivation, has a history of more than 400 years. The main production area of pineapple in Taiwan is around Tainan, Taichung and Kaohsiung. Pineapple cultivation area in Guangdong Province is larger, with more production, and the production area is concentrated in Shantou, Zhanjiang, Jiangmen and other areas and the suburbs of Guangzhou. The main production areas in Guangxi are Nanning, Wuming, Yongning, Ningming, Bobai and other counties and cities.
3, pineapple suitable for the growth of the environmental zone: temperature: pineapple originated in South America tropical high temperature and arid areas, like warmth, in the annual average of 24-27 (the most suitable for the growth of 15-40 ℃ range are able to grow, 15 ℃ below the growth of slow, 10 ℃ below the basic stop growing, 5 ℃ is the critical temperature of the cold damage.
4, planting depth is generally not more than 1/5 of the bud length is appropriate. After insertion, put in the shade, keep the potting soil dry. In the temperature of 22 ~ 24 ℃ about 1 month after the root. Root growth temperature for 29-31 ℃, below 5 ℃ or higher than 43 ℃ that is, stop growing; root growth began in March, and with the increase in temperature and rapid growth. late May to July growth peaked in October and tend to slow down, December to the following year, February near the surface of the root system due to cold and drought and death. Warm spring leaves began to draw, May-July leaf color green, faster growth, winter basically stopped drawing, leaf color reddish-yellow, such as cold damage to the leaf tissue dehydration and green, will dry up.
5, moisture: drought-tolerant, but growth and development still need a certain amount of water, in the annual rainfall of 500-2800mm can grow in the region, and to 1000-1500mm and the distribution of uniform for the most suitable, China's producing areas of the annual rainfall is more than 1,000mm, but also more concentrated in the growth of April-August, to meet the requirements of the water. Soil water shortage pineapple plant has its own regulation function, reduce transpiration intensity, slow down the respiration, saving water stored in the leaf, in order to maintain life activities; severe water shortage, the leaf is reddish-yellow, must be irrigated in a timely manner, in order to prevent drying out; too much rain, soil humidity, will make the root system rot, the emergence of plant heart rot or withering. Therefore, heavy rain or heavy rain must be timely drainage.
6, light: pineapple original growth in the semi-shaded tropical rainforest, more shade-tolerant, due to long-term artificial cultivation and domestication of light requirements increase, sufficient light under good growth, high fruit sugar content, good quality; light is not enough slow growth, high fruit acid content, poor quality. Light reduces 20%, yield drops 10%. But too much light, coupled with high temperatures, the leaves become reddish-yellow, the fruit is also easy to burn.
7, soil: pineapple on the soil adaptability is wider, because the root system is shallow and good gas, it is loose, well-drained, rich in organic matter, pH 5 ~ 5.5 sandy loam or mountain red soil is better, barren, sticky, heavy, poorly drained soils as well as a high water table are not conducive to the growth of pineapple.
8, wind: pineapple dwarf, wind damage direct impact is relatively small, the wind is also conducive to respiration below level 3. Strong typhoons, gales will also blow down the plant, blow broken fruit stalks, twisted leaves, affecting the normal growth and development; cold winds and cold rains in winter will cause heart rot.
