NOVELTY - Soilless culture matrix comprises 70-80 kg of perlite, 8-10 kg of zeolite, 5-10 kg of vermiculite, 10-15 kg of plant ash, 20-30 kg of modified oil-tea shell, 8-15 kg of tobacco leftovers and culture medium including 5-10 kg of slow release nutrient fertilizer, where the slow release nutrient fertilizer comprises 0.5-1.5 kg of potassium dihydrogen phosphate, 0.2-0.5 kg of ammonium phosphate, 0.4-0.6 kg of urea, of copper sulfate, 0.01-0.03 kg of zinc sulfate, 0.01-0.03 kg of ferrous sulfate, 0.1-0.3 kg of boric acid, 0.005-0.01 kg of ammonium citrate, vitamin A, vitamin B12 and vitamin K.    USE - Soilless culture matrix.    ADVANTAGE - The soilless culture matrix can be effectively and economically prepared in eco-friendly manner with high air permeability and improved scattering property.    DETAILED DESCRIPTION - Soilless culture matrix comprises 70-80 kg of perlite, 8-10 kg of zeolite, 5-10 kg of vermiculite, 10-15 kg of plant ash, 20-30 kg of modified oil-tea shell, 8-15 kg of tobacco leftovers and culture medium including 5-10 kg of slow release nutrient fertilizer, where the slow release nutrient fertilizer comprises 0.5-1.5 kg of potassium dihydrogen phosphate, 0.2-0.5 kg of ammonium phosphate, 0.4-0.6 kg of urea, of copper sulfate, 0.01-0.03 kg of zinc sulfate, 0.01-0.03 kg of ferrous sulfate, 0.1-0.3 kg of boric acid, 0.005-0.01 kg of ammonium citrate, 0.01-0.03 kg of vitamin A, 0.01-0.02 kg of vitamin B12 and 0.001-0.003 kg of vitamin K, the slow release nutrient fertilizer is prepared by dissolving nutrient substance into the water, adding nutrient substance with 5-8 times of soil algae, 1 -2 wt.% of sodium carboxymethyl cellulose, 4-5 wt.% of light calcium carbonate, 1-3 wt.% of sodium lauryl sulfate, uniformly stirring the dissolved mixture, and granulating the stirred mixture and then spray drying, and the plant ash is prepared by weighing 1-2 pts. wt. of nanocalcium carbonate, 2-3 pts. wt. of polyoxyethylene octylphenol ether as emulsifying agent OP-10, 1-2 pts. wt. of lauryl sodium sulfate, 1-2 pts. wt. of acetyl triethyl citrate, 1-2 pts. wt. of calcium superphosphate, 1-3 pts. wt. of wintergreen, 8-9 pts. wt. of glutinous rice flour, 2-3 pts. wt. of sepiolite powder and balance amount of water, after adequately agitating the weighed mixture at rotating speed of 1000-1200 revolutions per minute for 1 hours and then granulating in a granulator with grain diameter of 4-5 mm. An INDEPENDENT CLAIM is included for preparing soilless culture matrix comprising adding modified oil-tea shell and tobacco leftovers into 10-15% of citric acid solution to soak for 3-4 hours, and then drying at 30-40 degrees C until the water content is 2-3 %, and uniformly mixing added materials, granulating the materials, then adding plant ash and slow-release nutrient fertilizer.
