Pineapple also contains oxalic acid, which will affect the body's absorption of calcium and iron. Soaking in salt water can neutralize its acidity and reduce the harm to the body.
Growth environment of pineapple
Pineapple has its own special growth habits. Most pineapples have rosette leaves. The base of the leaf cluster forms a leaf tube that can store water. The water needed for the growth and development of this kind of pineapple is not stored in the mesophyll, but in the groove naturally formed at the central growth point of the clustered leaves (that is, the unique rosette-shaped leaf tube). In the growing season, it is necessary to water frequently to keep the basin soil moist.
It is a special habit of pineapple to water the leaf tube frequently so that there is enough water in the leaf tube to make it grow sturdily. Pineapple has a wide adaptability to soil. Because of shallow roots, loose sandy loam or mountain red soil with good drainage and rich organic matter is better. Poor, sticky and poorly drained soil and high groundwater level are not conducive to pineapple growth.
Pineapple was originally grown in semi-shaded tropical rain forest, which was more shade-tolerant. Due to long-term artificial cultivation and domestication, the requirement for light increased. Good growth, high sugar content and good quality under sufficient light. Insufficient light leads to slow growth, high acid content and poor quality of fruit.
