The origami handmade pineapple folding method is as follows: First prepare a square piece of colored paper, fold it in half diagonally, and unfold it.
Then fold the four corners to the midpoint.
Continue to fold the left and right corners to the midpoint.
Then continue to fold the upper and lower corners, but fold them smaller.
Use double-sided tape to stick the four folded corners together, turn it over, and the pineapple body is ready.
Take another square piece of green paper and fold it in half diagonally.
Fold both sides to the center line, turn over, align both sides to the center line and continue folding.
Then fold the two corners toward the middle, and the leaves are folded.
Fold off two green leaves and glue the leaves to the body of the pineapple.
Use a pencil to draw grids and dots on the surface of the pineapple, and the pineapple is ready to be folded.
Pineapple (scientific name: ananas comosus) is one of the famous tropical fruits.
Pineapples are native to the Amazon River Basin in Brazil and Paraguay in South America and were introduced to China from Brazil in the 16th century.
It has now spread throughout the tropics.
The edible part is mainly composed of the fleshy enlarged inflorescence axis and the flowers arranged in a spiral shape on the periphery. The flowers are usually not strong, and the persistent perianth lobes form a cavity, which contains shrunken stamens and styles.
The fibers of the leaves are very tough and can be used to make fabrics, ropes, nets and paper.
Pineapple originates from Brazil and was introduced to China in the early 16th century. It was also introduced to Taiwan. "The fruit grows among leaves. The peel is like jackfruit and is yellow in color. The liquid is sweet and sour. Because the tip has green leaves like a phoenix tail, it is named pineapple."
The mainland is named after jackfruit.
Later, the people of Taiwan carried out cultivation and produced a new variety of golden pineapple (eyeless pineapple).
So pineapple and pineapple are different names for the same fruit, and pineapples in stores generally refer to the eyeless pineapple variety.
Pineapples have their own special growth habits.
Most pineapples have rosette-shaped leaves.
The base of the leaf cluster forms a leaf tube that can store water.
The water required for the growth and development of this type of pineapple is not stored in the mesophyll, but in the naturally formed grooves at the central growth points of the clusters of leaves (i.e. the unique rosette-shaped leaf tubes). In addition to regular watering during the growing season,
Keep the potting soil moist.
It is also necessary to water the leaf tube frequently so that sufficient water is stored in the leaf tube so that it can grow vigorously. This is a special habit of pineapple.
Another special habit of most ornamental pineapples is that they only bloom once in their life. After flowering, the mother plant lives for a while and then dies. At this time, one to several tiller (niè) buds sprout at the base of the stem or root of the mother plant.
Tiller buds are good material for propagating new plants.
Pineapple originally grew in semi-shaded tropical rainforests and is relatively shade-tolerant. Due to long-term artificial cultivation and domestication, its light requirements have increased. It grows well under sufficient light, and the fruit has high sugar content and good quality; under insufficient light, it grows slowly and the fruit contains acid.
High quantity, poor quality.
If the light is reduced by 20%, the yield will be reduced by 10%.
However, if the light is too strong and the temperature is high, the leaves will turn red and yellow, and the fruits will be easily burned.
Pineapple has a wide adaptability to soil. Since the root system is shallow and aerobic, sandy loam or mountain red soil that is loose, well-drained, rich in organic matter, and has a pH value of 5 to 5.5 is better. Soil that is lean, heavy, and poorly drained is better.
High groundwater levels are not conducive to pineapple growth.
