NOVELTY - A cucumber soilless cultivation method involves preparing cultivation tank. Matrix is prepared by using biogas: mushroom residue: perlite at ratio of 1: 1: 1 per m3 matrix organic ecotype special fertilizer, 1kg urea, 1kg cake fertilizer, 3kg chicken manure, 1kg phosphoric acid and water, fully fermented maturity. Sowing process is performed. Colonization process is performed. Field management is performed followed by controlling pest to complete elimination of indoor pest source, supplementing chlorfluazuron, and pesticides to control pollution, harvesting after harvest for times a day.    USE - Method for soilless cultivation of cucumber.    ADVANTAGE - The method enables soilless cultivation of cucumber in simple and cost effective manner.    DETAILED DESCRIPTION - A cucumber soilless cultivation method involves preparing cultivation tank made with polystyrene plates, width of 60-80cm, depth of 15-25cm, tank bottom edge of the film and the soil laid isolated from soil pests infection. Matrix is prepared by using biogas: mushroom residue: perlite at ratio of 1: 1: 1 per m3 matrix organic ecotype special fertilizer, 1kg urea, 1kg cake fertilizer, 3kg chicken manure, 1kg phosphoric acid and water, fully fermented maturity. Species is selected by selecting whole fruits female line type resistance to low light, high yield, disease-resistant varieties of early maturing and crops arrangements July nursery, greenhouse planting in late August. Sowing process is performed by soaking cucumber seeds in water for 2-3 hours, removing loose seeds, dry out, placing in 4% formalin 100 times for 30min, rinsing with water after use, at 30 degrees C for 12-16 hours, sterilizing matrix mixing, transfer to a plate, the back pressure hole, placing in germination chamber for germination, plug moving to the bench in the greenhouse nursery, foliar application for once every 7days nutrient solution. Colonization process is performed began when two leaves, use pest-free, consistent with the size of the robust seedlings, planting double row dislocation, peer spacing 50cm, base of the plant site from the same groove side 10cm, slightly higher than the seedlings lump matrix. Field management is performed by controlling seedling daytime temperature at 18-25 degrees C, at night of 15-18 degrees C, controlling daytime temperature at 25-28 degrees C, night temperature of 15-18 degrees C, seedling per m2 per day, irrigating, top dressing fertilizer before flowering topdressing chicken manure, composting 20g beans cypress, months before harvest stop dressing, sprinkle fertilizer evenly 5cm in the outer surface of the substrate from the roots, combined with foliar spraying fertilizer supplement, spraying potassium dihydrogen phosphate, single pole pruning, fruit set on the main vine, removing all flower buds and lateral branches, leaving each section wide two melons, timely removal of lateral branches, old leaves, diseased leaves, followed by controlling pest to complete elimination of indoor pest source, indoor hanging yellow sticky trap and kill whiteflies and aphids, supplementing chlorfluazuron, and pesticides to control pollution, harvesting early removal of root melon, turning light green to dark green cucumbers, harvesting after the harvest for times a day.
