Biological characteristics of rubber trees


Rubber tree is a long-term industrial plant, it can last up to sixty-seven years, but the extraction time is from 20 to 40 years. The older trees become exhausted, the productivity of the latex is reduced and exhausted. Longevity and high productivity are due to its well-grown flour.

Rubber tree body
The rubber tree is straight and rounded, up to a height of 2m to 3m, the scene. This branch of slang in the vocabulary is called ‘collar’. Later on, the pus on the body also from this ‘collar’ to the root. The root of the slang in the profession is called the ‘elephant’s leg’, because indeed it stretches out like the shape of the elephant’s foot (while the stem from the root to the ‘collar’ goes smoothly and The size of each elephant is so different.

Rubber tree roots

Normally, when the stem is high, the root of the mouse is long, so it can keep the stand for the tree when the rain is heavy wind.

In addition, the higher the plant, the more important it is to root the root, the root of which is to suck the mineral water in the deep soil, as much as possible to grow the plant, especially in the drought season.

Rubber tree has two types of roots:

Root: big, strong, 3 to 5m long, plug deep into the ground to absorb water, and help the tree stand firm.
Hibiscus: is a myriad of small roots that grow around the rooted, branched branch through the cross as a network of nourishing soil nutrients to support the plant. The roots are small, but many, above the foliage to reach where the roots grow to spread there. Therefore, when plowing to kill grass in the plot we should plow with a shallow about 10 inches to avoid breaking the roots.
Tree bark: Rubber bush is a source of latex because it contains a lot of latex, which is a major source of income for growers, so try to avoid damage to the trunk. The crust that is crushed, peeled or roughly humped will greatly affect the latex yield of the plant.

The tree trunk consists of the following three layers:

Dirty skin: This is the outer shell, dark brown, because it is dead cells, so it does not contain pus. However, the function of this dermal layer is important for the growth of the plant, as it protects the inner layers of the skin.
Sandy leather: The hard shell in the dirt, also known as the hard shell, contains pus but not much.
Silk skin: The innermost soft shell, a few inches thick, contains the most pus. The latex of the tree does not lie vertically in the trunk, which is tilted from right to left, forming an angle of 5 degrees from the vertical line, from the bottom up.
Leaf: Leafy leaves are double leaves, each consists of 3 leaflets. In the leaves also contains many latex, while the petiole is a bile duct, enough to attract bees and some other insects to attract honey. When young leaves are brownish in color; The leaves are light green and soft. In old age, the leaves are hard and dark green.

The function of the rubber leaves is to photosynthesize and convert the resins into plastics to feed the plants.

The latex meridians in the rubber leaves contribute to the increase in latex yield. Therefore, during the season of leaves change (Lunar New Year), we have to temporarily stop shaving. Wait until the leaves grow, so that the young leaves are stable, the new tree to pus and shave again.

Flowers: Rubber trees planted to the fourth year flowers. Yellow flowers, unicorn, grows into branches in axillary leaves. Male and female flowers grow on one branch and each branch usually has 12 clusters, on which females account for only one tenth of male flowers.

Although the flowers are common, but usually flowers ripen in front of the flowers after ripening, but that does not interfere with the fertilization of the flowers, because they are crossed. Male pollen from other branches, or other plants, will be pollinated by wind or insects.

The flowering season of the rubber tree usually comes after the Lunar New Year, when the tree has finished changing its new leaves.

Left: Rubber has 3 compartments in 3 separate chambers. Each such chamber contains a grain inside. When the old hard shell hard, ivory white, cracked walls to shoot bullets down around the root.

Seed: Depending on the seed that rubber seeds are oval or round. Very large, with a diameter of 1.5 to 2cm. Often when the pods are light brown, on which there are more dark brown color. The seed coat is smooth and very hard, and contains granules of embryos and seedlings.

Due to the hard seed coat, when sowing, we have to tap lightly on the cracked seeds to make the new seeds germinable. Rubber seeds in addition to breeding, also as food for cattle and fertilizer very well.

Rubber seeds if roasted at a temperature of 35 to 40 degrees C out of poison is cyanydric acid, then grinded to use as animal feed. It is best to eat less.
Rubber seed contains more than 30% of oil. This oil, which contains cyanydric acid, is a highly toxic reducing agent that can be used in humans and cattle. Latex is used to make paint, soaps. The seeds after the squeeze to make fertilizer.
In short, rubber trees are very useful for human life. The rubber wood, the previous day is considered wood, but if the removal of termites become valuable, such as furniture, paper pulp.
