Hydroponics
Hydroponic definition -> hydro = water, ponos = power, hydroponics = empower water.Do not be written and pronounced as HYDROPHONIC, because phonos = voice, so that it becomes the sound of water. Pain to hear it!
Definition = miscellaneous! Soilless culture, cultivation in the greenhouse, organic cultivation, the important results are superior in quality and quantity, water saving, energy saving, versatility / agility is high, environmentally friendly, no contamination by E. coli bacteria, and produce products that are healthy, hygienic, aromatic, with protein and vitamins in abundance, and look attractive and appetizing to consume.
Admittedly require large capitalization, high managerial skills, advanced network marketing, and human resources that are reliable! Do it!
SOME SYSTEM hydroponic cultivation.
1 Using the media, for example:
a) Soil.
b) Sand. It has been abandoned, because it is expensive, difficult to obtain, expensive transportation, high distribution costs in the garden, heavy, dense, small air cavities, dense compact root growth difficult.
c) Topsoil, Compost.
d) Cocopeat, coir peat powder.
e). Husk charcoal.
2 Using the medium of water.
a) NFT - Nutrient Film Technic - Hydroponic Gutter ramps.
NFT system, made in Belgium, imported ready-to-wear, in Indonesia belonging to the late Ir Sunarto in Jln Semboja, Margonda, Depok, year 1983, I made a local version using household rain gutters. Gutters with the flatness of tangency 5%, the nutrient solution to flow with thickness 3-4 mm, making it rich in dissolved oxygen, because ripples swirling in direct contact with air. NFT systems are very popular!b) DFT - Deep Flow Technic - Hydroponics Gutters Flat.
The depth of water is maintained at a depth of no more than 8 cm, so that the load is not too heavy for the gutters. Water enters at one end and exit through the hole at a height of 8 cm at the other end. Aeration in this system is less than perfect, so it is difficult to achieve high production.Between Styrofoam mounted at a height of 10 cm, with the water surface at a height of 8 cm, no air cavity 2 cm thick, for aeration.
c). Floating Raft Technic - Floating Raft Hydroponics.
Pool with a depth of 40 cm, filled with nutrient solution as thick as 30 cm, 3 cm thick styrofoam diapungi, given the decades of the planting hole, planting vegetable seedlings child leaves, the roots dangling into the nutrient solution. With the added air blower into the reservoir, to increase levels of dissolved oxygen. Management of installation is very easy.3 Using the medium of water and soil / mud.
a) Tidal Hydroponics - Ebb and Flood.
Usually used in the production of ornamental plants in pots. Pots were placed in tubs and pots feet high nutrient solution digenang by 4-8 cm, for a few minutes, then a solution of the gravity flow out again, done once every few days. Pot contains media, usually mixed soil organic material. Height of soaking solution should be limited, to prevent the media floats and destroy crops.b) Hydroponic immersion.
Rice fields is an immersion hydroponic system, with water flowing slowly, driven by the water flow at the inlet of 1 liter / hectare / sec, a large amount. (Excluded: Rainfed rice fields, which receive water supply from rain, and the water retained in the soil as long as possible.)4 Using air as a medium
Aeroponics. Children seedlings were planted into the planting hole, which was made on a piece of styrofoam, freely swinging roots down. Covered by fog droplets nutrient solution, through sprinklers are driven by a high pressure pump, continuously without stopping, roots bathed in fine grains, the dissolved-oxygen content is very high, which is very supportive of the process of respiration. The solution is not the root collected and fed back to the tank / reservoir nutrient solution, for re-circulation. First Day of aeroponic system will be widely applied to transform and produce parent seed potatoes, and hence we must begin to focus on the technique of aeroponics. Successful experiments have also been done on aeroponic production of cut flowers of Chrysanthemum / Chrysanthemum and Lily. Age of the plant can be reduced from 12 weeks to 8 weeks. The number of flowers that bloom simultaneously can be increased from two to three florets. The brightness of colors and scents can also be improved a bit.anorganic salts to mix FERTILIZER hydroponics.
anorganic salt used in making the selected hydroponic fertilizer containing macro nutrients, which is essential, absolutely necessary in large quantities, to form the body of the plant, in order to high production quantity and quality. It is also necessary micro nutrients which is also essential, indispensable though in small amounts, and mostly act as enzymes.
Rows of elements are added regarded as "beneficial elements", elements favorable. Na can be a substitute for K, K-poor soils, with symptoms of drooping palm leaf midrib. Farmers fertilize with NaCl salt, so that the next midrib upright. Si, silicate, strengthen plant tissue, so it can not attack the fungus disease. Cl, chlorine, to be feared and avoided, as it can interfere with the household-water plant tissue, formation of giant cells, filled with water, the consistency of cell damage, leading to bland products without taste.
Nutrients that after entering into the plant body, constantly changing shape, into proteins, fats, etc., and do not be mistaken them roaming loose as individual elements. Usually the elements collected in vacuoles inside the cell, waiting processed by ribosomes which are also located in the cell, in order to be proteins, tissue / tissue, organ / organs, etc.
