Earthworms (Lumbricus rubellus) to nourish and maintain soil fertility. Earthworms will eat the organic material initially in the ground. Then this little creature down to the inside of the ground, the earthworms move organic material from upper layers to lower layers of soil. Earthworms when it moves to the bottom also makes pores that can improve soil aeration.
"Furthermore, earthworms also remove the dirt. Earthworm manure digestion that has passed through it, to contain certain hormones that do not have regular and good compost for plant growth," said Dr. Rahayu Widiastuti, Research Laboratory of Soil Biology, Bogor Agricultural University explained in beritabumi.or.id December 13, 2004.
That way, the earthworm is able to modify the environment and provide nutrients for other organisms. Earthworms can be referred to as ecosystem engineers.
Besides earthworms also include organisms that play a role in sustainable agriculture principled reduce chemical fertilizer that pollute the environment and groundwater pollution.
Earthworms are also known as decomposers. Hermaphrodite animals (double-sex) that play a role in the decomposition process by breaking down organic materials, trash and litter on the land on his life.
Reptile small animal that could be called Mr. Farmer or Farmer because his movement can menggemburkan hard ground. "As might be digging. On the hard ground, with its movement, can form pores. When the soil is very hard to eat later issued kascingnya," said Widiastuti.
Worms have extraordinary powers. Its strength can reach 40 times their weight. When earthworms weighing 50 kg it can propel the 2,000 kg weight. Indeed, the earthworm has a certain hormones that can make her body strong. Nutritious and for drug
In the world of health, earthworms are also used as a drug. Usually to cure typhus. Earthworms are dried and used as flour to be incorporated into the capsule. Prompts other users, so that his usefulness as a drug is more obvious, earthworms eaten fresh. For one recipe, 10 head of earthworms blender and then drink the liquid for three days.
Earthworms contain proteins with amino acids is more complete than the fish and meat. So the better nutritional value for food and cosmetic ingredients. In China the earthworm has been used as a cake mix. In Indonesia only for fodder. In China, the earthworm has been used as a cosmetic in the form of meal worms to smooth the skin. Classification
In biological classification, earthworms, including the Order of Oligo-chaeta, Class Chaetopoda, Philum annelids. In annelids Philum are 1,800 species of earthworms, which are grouped into five families scattered around the world. The largest number in North America, Europe and Western Asia, for the Family Lumbricidae with 220 species.
Earthworms have a long range from a few millimeters to 91 cm. But usually only a few centimeters in length.
Earthworm digestive system is very adaptive to the activities of eating and digging the soil pores. Worm swallows soil (including decomposition of organic residues in soil) or residues and crop residues on the soil surface.
Then cultivate strong muscles and removing the material is ingested through the digestive system that contains the form of enzymes and digestive juices mix with the material. It issued a digestive fluid amino acids, sugars and organic molecules from organic residues (including living protozoa, nematodes, bacteria, fungi and other microorganisms). The most kecill molecules absorbed through the intestinal worms membram land used for energy and cell synthesis.
Earthworms do not have a specific respiratory division. In the respiratory exchange takes place through the body surface.
Earthworms do not always reproduce the marriage itself through the system hermaphrodite (each individual to have male and female reproductive organs). Exchange of sperm occurs in the joint between two worms during mating.
Sperm and egg cells mature and liquid nutrients stored in the cocoon produced clitellum, a girdle conspicuous sepertii structure near the anterior end of body. The egg is fertilized by a sperm cell in a cocoon, then detached and settle in or on the ground. Eggs hatch after three weeks. Each cocoon produces two to twenty baby worms.
Earthworms are grouped in three plasma Epigeic, Endogeic and Anecic. Epigeic usually live above ground and eat dirt. Endogeic live below the ground surface is horizontal. Anecic living in deeper soil layers. |
